Technical Field

The present technology relates to a vehicle having a variable overall length and a method for varying the overall length of the vehicle.

Background

Two-wheeled vehicles (e.g., scooters and motorcycles) are often convenient vehicles. This is particularly true for urban environments where the distance traveled is typically short and the average speed is low.

It is often desirable to be able to transport goods (e.g., a driver's shopping, work packages) or other passengers. Some vehicles are configured to provide a cargo space to transport a plurality of passengers. For example, the vehicle may be constructed in a more slender manner to provide additional space between the seat and the rear wheel. Some bicycles have a cargo area between the front wheel and the handlebar. There are also full-sized tricycles (commonly referred to as tricycles) having a cargo space between two front wheels or two rear wheels depending on the wheel configuration of the tricycle.

However, in such vehicles with additional built-in cargo space, overall mobility is often reduced. By having a longer wheelbase or three wheels rather than two, cornering is often adversely affected due to the larger wheelbase or longer vehicle length.

There is a need for a vehicle that can carry cargo without at least some of the aforementioned inconveniences.

Detailed Description

The present technology will be described herein with respect to a two-wheeled straddle seat electric vehicle 100. As shown, the vehicle 100 is embodied as an electric scooter 100, although at least some aspects of the present technique may also be practiced in different two-wheeled vehicles, such as motorcycles. It is also contemplated that at least some aspects of the present technology may also be practiced with straddle-type seating vehicles having three wheels, including vehicles having two front wheels and one rear wheel and vehicles having one front wheel and two rear wheels.

A vehicle 100 according to the present technique will now be described in detail with reference to fig. 1 to 6. The vehicle 100 has a front end 102 and a rear end 104 defined in line with the forward direction of travel of the vehicle 100. As will be described herein, the vehicle 100 has a selectively variable overall length. Accordingly, the size of the storage space 101 defined in the vehicle 100 between the front end 102 and the rear end 104 (see fig. 3 and 4) may be selectively increased or decreased longitudinally (i.e., in the forward driving direction) as desired or desired by an operator of the vehicle 100.

The vehicle 100 is formed of two connected subsections, referred to herein as modules. Specifically, the vehicle 100 is formed from a front module 110 and a rear module 150. The front module 110 includes a front end 102 and is disposed forward of a rear module 150 that includes a rear end 104. The modules 110, 150 are selectively movably coupled together by two extension assemblies 190, described in more detail below.

The front module 110 has a front frame portion 112, and various components of the vehicle 100 are supported on the front frame portion 112. The front module 110 includes a front wheel 114 mounted to the front frame portion 112 by a front suspension assembly 116. The front wheel 114 includes a rim and a tire attached thereto. In the present embodiment, the front suspension assembly 116 is a front fork suspension 116 that supports the front wheel 114. Depending on the embodiment, different types of suspension assemblies may be used as the front suspension assembly 116 to support the front wheels 114.

The front module 110 also includes a straddle seat 118 mounted to the front frame portion 112 and generally laterally aligned with the front and rear wheels 114, 154. In the illustrated embodiment, the straddle seat 118 is intended to accommodate a single adult sized rider, i.e., driver. It is contemplated that the vehicle 100 may also be provided with one or more passenger seats disposed behind the driver seat 118, depending on the embodiment, connected to either the front module 110 or the rear module 150. It is also contemplated that the straddle seat 118 may include a passenger seat portion for accommodating a passenger on the seat 118 with the driver.

The battery 140 is disposed below the straddle seat 118, is part of the front module 110, and is supported by and connected to the front frame portion 112. The battery 140 provides power to a motor assembly 170 that drives the vehicle 100. Vehicle 100 includes electrical cord 141 (fig. 3) that electrically and operatively connects battery 140 to motor assembly 170. Since the motor assembly 170 is disposed on the rear module 150, the wires 141 extend from the front module 110 to the rear module 150. Further details regarding the motor assembly 170 and the connection of the battery 140 to the motor assembly 170 are set forth below.

In other embodiments, it can be seen (and as will be described further below) that the battery 140 can be connected to a rear frame portion 152 of the rear module 150. In some embodiments, the battery 140 may be disposed only partially under the seat 118. It is also contemplated that the battery 140 may be disposed on the vehicle 100 at a location other than under the seat 118.

The front module 110 includes a steering assembly 130 disposed forward of the seat 118 for steering the vehicle 100. The steering assembly 130 includes a steering column 131 connected to the front suspension assembly 116. The top end of the steering column 131 is connected to a handlebar 132. The driver uses handlebar 132 to steer vehicle 100 by turning front wheel 114 via steering column 131. A twist grip throttle 133 (see FIGS. 4 and 5) is operatively connected to the right side of handlebar 132 for controlling vehicle speed. It is contemplated that the twist-grip throttle 133 may be replaced by a throttle lever or some other type of throttle input device.

The front module 110 also includes a front fender assembly 125. The front fender assembly 125 is connected to the front suspension assembly 116 and extends over a portion of the top side of the front wheel 114. It is contemplated that the front fender assembly 125 may be omitted.

The front module 110 also includes a front brake assembly 120 operatively connected to the front wheel 114. The front brake assembly 120 is a disc brake assembly mounted on the main axle of the front wheel 114. Other types of brake assemblies are also contemplated. Each brake assembly 120 includes a rotor 122 mounted on the hub and a fixed caliper 124 spanning the rotor 122. Brake pads (not shown) are mounted to the caliper 124 so as to be disposed between the rotor 122 and the caliper 124 on both sides of the rotor 122. Front brake assembly 120 also includes hydraulic lines (not shown) for actuating calipers 124 to brake front wheels 114. In some embodiments, front brake assembly 120 may include a solenoid for electronically controlling the actuation of caliper 124 to brake front wheel 114.

The front module 110 includes a brake sensor 128 (shown schematically) for detecting braking of the front wheels 114. In the illustration, the brake sensor 128 forms a portion of the front brake assembly 120. A brake sensor 128 is included for sensing when the front brake assembly 120 has been actuated and when the front wheel 114 has been rotationally locked by the brake assembly 120. The use of brake sensor 128 will be further described below. It is contemplated that in alternative embodiments, brake sensor 128 may be a front wheel speed sensor, and in particular may be operable to detect when the front wheel speed is zero.

The handlebar 132 includes two brake levers 134 (see fig. 4 and 5) for controlling braking of the vehicle 100. The left brake lever 134 is operatively connected to the front brake assembly 120. The right brake lever 134 is connected to a rear brake assembly 166, and the rear brake assembly 166 is operatively connected to the rear wheel 154. The rear brake assembly 166 is similar to the front brake assembly 120, but may be embodied in a variety of forms and will not be described in further detail herein. In some embodiments, the front and rear brake assemblies 120, 166 are part of a vehicle stability system that also includes hydraulic pumps, manifolds, and valves fluidly connected to the brake assemblies 120, 166. In such embodiments, the brake sensor 128 may be a hydraulic pressure sensor 128 located in the hydraulic manifold at a location remote from the brake assemblies 120, 166.

It is also contemplated that the brake lever 134 could be replaced by a different control mechanism to control the brake assemblies 120, 166. For example, in some embodiments of the vehicle 100, a brake pedal may be included that is connected to the front frame portion 112. It is also contemplated that the brake assemblies 120, 166 may be controlled by the same mechanism, such as only one brake lever 134. It is further contemplated that one of the two brake levers 134 may be used to control the regenerative braking function of the motor assembly 170, while the other brake lever 134 controls the brake assemblies 120, 160. It is also contemplated that a single brake lever 134 may be used to control both the regenerative braking function and the brake assemblies 120, 160.

In this embodiment, the right brake lever 134 controls the rear brake assembly 166 via a "control-by-wire" arrangement, while the left brake lever 134 is mechanically connected to the front brake assembly 120, including via a hydraulic fluid pump (not shown) and hydraulic lines. This is just one non-limiting example of a brake control device. In different embodiments, the control of the front and rear brake assemblies 120, 166 by the brake lever 134 can be implemented in different ways.

Depending on the particular implementation, the front module 110 may include more or fewer components of the vehicle 100.

The rear module 150 will now be described in more detail. Similar to the front module 110, the rear module 150 may include more or fewer components of the vehicle 100.

The rear module 150 includes a rear frame portion 152, with various components of the vehicle 100 supported on the rear frame portion 152. The rear module 150 includes a rear wheel 154 mounted to a rear frame portion 152 by a rear suspension assembly 156. The rear wheel 154 includes a rim and a tire attached thereto.

In this embodiment, the rear suspension assembly 156 includes a swing arm assembly 160. In some cases, the rear suspension assembly 156 may be implemented in different ways. The swing arm assembly 160 includes a swing arm 162 and a shock absorber 164. Swing arm 162 is pivotally mounted at its front to rear frame portion 152. Shock absorbers 164 are connected between swing arms 162 and rear frame portion 152.

The rear wheel 154 is rotatably mounted to a rear end of a swing arm 162, and the swing arm 162 extends to the left of the rear wheel 154. The rear module 150 also includes the motor assembly 170 briefly mentioned above. Rear wheels 154 are operatively connected to motor assembly 170 for selectively driving rear wheels 154 to propel vehicle 100 via rear wheels 154. In some embodiments, motor assembly 170 may alternatively be connected to front wheels 114 to form an all-wheel or front-wheel drive vehicle.

The rear module 150 also includes a rear fender assembly 165. A rear fender 165 extends rearward from the swing arm 162 and then extends to the rear of the rear wheel 154. It is contemplated that the rear fender assembly 165 may be omitted.

The motor assembly 170 is supported by the swing arm 162 as shown in fig. 4 and 5. However, it is contemplated that in some embodiments, motor assembly 170 may be supported by rear frame portion 152.

The motor assembly 170 includes a motor (not separately shown) and an inverter (not separately shown, also referred to as a motor controller, an adjustable speed drive, or a variable speed drive) for controlling the current from the battery 140 to the motor. The motor assembly 170 is communicatively connected to a twist-grip throttle 133 on the handle 132 for receiving signals therefrom to control the speed at which the motor assembly 170 drives the rear wheels 154.

The vehicle 100 includes a speed sensor 172 for sensing the speed of the vehicle 100 and for sending a signal related to the speed of the vehicle 100 and/or indicating that the vehicle 100 is stationary, as will be discussed in more detail below. In the present embodiment, the speed sensor 172 is part of the motor assembly 170, although it is contemplated that the speed sensor 172 may be arranged or implemented differently. For example, the speed sensor 172 may be directly connected to the front wheels 114 and/or the rear wheels 154.

As described above, the vehicle 100 includes two extension assemblies 190 to selectively movably connect the rear module 150 to the front module 110. Specifically, a right extension assembly 190 is connected between the right side of the front frame portion 112 and the right side of the rear frame portion 152, and a left extension assembly 190 is connected between the left side of the front frame portion 112 and the left side of the rear frame portion 152.

In some embodiments, it is contemplated that the vehicle 100 may include only one extension assembly 190 on the right side, the left side, or along the bottom side of the frame portions 112, 152. It is also contemplated that the vehicle 100 may include more than two extension assemblies 190, depending on the specific details of the vehicle implementation. The extension assembly 190 is a selectively extendable and retractable mechanism that provides and supports selective changes in the overall length of the vehicle 100.

In this embodiment, the vehicle 100 is selectively variable between three different overall lengths, characterized by three extended positions of the extension assembly 190: contracted, partially extended, or extended. In the collapsed position, as shown in FIG. 1, the storage space 101 is fully collapsed, the extension assembly 190 is fully collapsed, and the vehicle 100 has its minimum overall length. In the extended position, as shown in FIG. 3, the storage space 101 is fully deployed, the extension assembly 190 is fully extended, and the vehicle 100 is disposed at its maximum overall length. In the partially extended position, as shown in fig. 2, storage space 101 and extension assembly 190 are partially extended and the overall length of vehicle 100 is between the minimum overall length of vehicle 100 and the maximum overall length of vehicle 100. In some embodiments, the vehicle 100 may have more or fewer extended positions, including in some cases only being selectively disposable between a minimum overall length and a maximum overall length. In other embodiments, the vehicle 100 may be controllably set to any overall length between the minimum and maximum overall lengths.

While the extension assembly 190 does not control the relative positioning of the front and rear modules 110, 150 (control of relative positioning will be described below), the extension assembly 190 is an extendable/retractable mechanism that provides rigidity and support between the front and rear modules 110, 150, helping to maintain the structural integrity of the vehicle 100 to accommodate different extended positions of the front and rear modules 110, 150.

In this embodiment, the vehicle 100 also includes an extendable support bar 135 that is pivotally connected between the front module 110 and the rear module 150 to help maintain the rigidity of the vehicle 100 when the vehicle 100 is in a partially extended and extended position. It is contemplated that the vehicle 100 may include additional or non-extendable support bars 135, depending on the particular implementation. In some embodiments, it is also contemplated that the vehicle 100 may include a foldable or retractable floor portion between the front module 110 and the rear module 150.

Each extension assembly 190 includes a front 192 connected to the front module 110 and a rear 194 connected to the rear module 150. In the present embodiment, the front 192 and the rear 194 are secured to the front module 110 and the rear module 150, but it is contemplated that the extension assembly 190 may be connected to the front module 110 and the rear module 150 in a different manner.

Each extension assembly 190 also includes an intermediate portion 196 integrally connected to the rear portion 194 and slidably connected to the front portion 192. Specifically, the intermediate portion 196 is a telescoping member 196, the telescoping member 196 being received within the front portion 192 as the rear portion 194 translates forward toward the front portion 192. It is contemplated that the extension assembly 190 may include additional telescoping portions. It is also contemplated that the extension assembly 190 may utilize different mechanisms to allow expansion and contraction. For example, in some embodiments, the extension assembly 190 may include a non-telescoping member, such as a flexing or folding member.

As schematically shown in fig. 3, the left extension assembly 190 defines a passage 197 therethrough for routing wiring (control lines, cables, wires, etc.) from the front module 110 to the rear module 150. By passing the wiring through the extension assembly 190, the passage 197 helps to protect the wiring from operational interference (blocked by obstacles, etc.) and improves the aesthetics of the vehicle 100 (hiding the wiring from view). In this embodiment, wires 141 connecting battery 140 to motor assembly 170 extend from front module 110 to rear module 150 through channels 197. In some embodiments, the rope 141 is a spring coiled rope such that the length of the rope 141 may increase as the overall length of the vehicle 100 increases.

The left extension assembly 190 includes an extension sensor 198 for sensing the extended position of the extension assembly 190. In some embodiments, the extension sensor 198 may additionally or alternatively sense the position of the front module 110 relative to the rear module 150.

The left extension assembly also includes an extension lock 199 to selectively lock the extension assembly 190 in the extended position. The extension lock 199 helps prevent the extension and/or retraction of the extension assembly 190 when not needed and thus limits the change in the overall length of the vehicle 100, such as when the vehicle 100 is traveling or maneuvering. Since the extension assemblies 190 and the front and rear modules 110, 150 are relatively rigid, locking one of the extension assemblies 190 is sufficient to lock the overall length of the vehicle 100. In some embodiments, the extension lock 199 may automatically lock the extension assembly 190 whenever the vehicle 100 is moving.

While the extension sensor 198 and the extension lock 199 are part of the left extension assembly 190 in this embodiment, this is merely one non-limiting example. In some embodiments, the sensor 198 and lock 199 may be present in the right extension assembly 190 in place of, or in addition to, the sensor 198 and lock 199 of the left extension assembly 190. It is also contemplated that the extension sensor 198 may be present in one extension assembly 190 and the extension lock 199 may be included in another extension assembly 190.

To control the selective overall length of the vehicle 100 and to selectively increase or decrease the storage space 101 defined in the vehicle 100, the vehicle 100 includes a vehicle control unit 180 (shown schematically) disposed in the front module 110. According to an embodiment, the vehicle control unit 180 may alternatively be provided in the rear module 150.

The vehicle control unit 180 is a computer-implemented device capable of receiving and transmitting electronic signals and instructions. Although in the present embodiment, the vehicle control unit 180 is a separate device, it is contemplated that the vehicle control unit 180 may be implemented as part of another computing system in the vehicle 100. For example, the vehicle control unit 180 may be implemented by a motor control unit that manages the motor assembly 170.

Vehicle control unit 180 controls selective changes in the overall length of vehicle 100 by communicating with components of vehicle 100, including motor assembly 170, for changing the overall length of vehicle 100 (described in detail below). As schematically shown in FIG. 6, the vehicle control unit 180 is communicatively connected to various components associated with selectively changing the overall length of the vehicle 100, including the motor assembly 170, the front brake assembly 120, the brake sensor 128, the speed sensor 172, the extension sensor 198, and the extension lock 199. In embodiments including hydraulic pumps fluidly connected to the brake assemblies 120, 166, the vehicle control unit 180 may be communicatively connected to the front brake assembly 120 through hydraulic pumps, manifolds, and valves.

The vehicle 100 includes a control line 181 that communicatively connects a vehicle control unit 180 to the motor assembly 170. As described below with reference to another embodiment, in some cases, the vehicle control unit 180 and the motor assembly 170 may be wirelessly connected or otherwise connected. Since the vehicle control unit 180 is disposed in the front module 110 and the electric motor assembly 170 is disposed on the rear module 150, the control wires 181 extend from the vehicle control unit 180 to the electric motor assembly 170 through one of the extension assemblies 190. Specifically, the control line 181 extends from the vehicle control unit 180 to the motor assembly 170 via a passage 197 in the left extension assembly 190. As noted above, it is contemplated that the right extension assembly 190 may alternatively or additionally define a channel therein. In such a case, control line 181 may instead extend through right extension assembly 190. In some embodiments, the control wire 181 may be a spring coil to accommodate selective variation in the distance between the vehicle control unit 180 and the motor assembly 170.

As described above, the vehicle control unit 180 is communicatively connected to the front brake assembly 120 and is adapted to actuate the front brake assembly 120 to rotationally lock the front wheels 114. As described in more detail below, in some cases, the vehicle control unit 180 actuates the front brake assembly 120 and thereby rotationally locks the front wheels 114. Vehicle control unit 180 is also communicatively connected to brake sensor 128 to receive one or more signals from brake sensor 128 indicating that front wheels 114 are (or are not) rotationally locked by front brake assembly 120. As will be described below, in some embodiments, the vehicle control unit 180 then controls the selective change in the overall length of the vehicle 100 as a function of the signal received from the brake sensor 128.

Extension sensor 198 is also communicatively connected to vehicle control unit 180. Depending on the particular implementation, the extension sensor 198 provides an indication to the vehicle control unit 180 of the extended position of the extension assembly 190 and/or the position of the front module 110 relative to the rear module 150.

The speed sensor 172 is also communicatively connected with the vehicle control unit 180. Depending on the particular implementation, the speed sensor 172 provides one or more signals to the vehicle control unit 180 indicative of the speed of the vehicle 100 and/or indicative of the vehicle 100 being stationary.

To receive an indication from the operator of a desired extended position of the vehicle 100, the vehicle 100 includes a mode selector 185 communicatively connected with the vehicle control unit 180. The mode selector 185 allows the operator to select between one of three extended positions: contracted, partially extended, or extended. In embodiments where the vehicle 100 has more or fewer extended positions, it is contemplated that the mode selector 185 may be configured to select from different extended positions accordingly.

In the present embodiment, the mode selector 185 is provided on the handlebar 132 in the front module 110 and connected to the handlebar 132. Thus, the mode selector 185 is provided at a place easily reached by the operator so as to selectively change the overall length of the vehicle 100. However, in some embodiments, the mode selector 185 may be disposed elsewhere on the vehicle 100. In some embodiments, for example, the mode selector 185 may be placed near the seat 118. The mode selector 185 may also be connected to the rear module 150 as will be described with reference to another embodiment herein.

The mode selector 185 is arranged and configured to receive an indication from the operator that the operator wishes to change the overall length of the vehicle 100, which is then communicated to the vehicle control unit 180 to instruct the vehicle 100 to retract or extend the rear module 150 relative to the front module 110. In this embodiment, the mode selector 185 is an option on a multifunction meter formed by an interactive screen device. It is contemplated that the mode selector 185 can be implemented in a variety of forms, including but not limited to: switches, dials, buttons, and a plurality of buttons.

Since the seat 118, the steering assembly 130, the battery 140, and the mode selector 185 are all connected to the front module 110, selectively increasing the overall length of the vehicle 100 creates a storage space 101 within the vehicle 100 between the seat 118 and the rear wheels 154. Referring additionally to fig. 7, a method 200 for selectively changing the overall length of the vehicle 100 will now be described.

In the present embodiment, the method 200 is performed by the vehicle control unit 180. It is contemplated that method 200 may be performed by a different computer-implemented device of vehicle 100, such as a control unit associated with motor assembly 170.

The method 200 begins at step 210 by receiving an indication from the mode selector 185 to change the overall length of the vehicle 100. According to this embodiment, the operator toggles the switches of the mode selector 185 to select their preferred extended position, but the details of this step will vary for different embodiments of the mechanism of the mode selector 185.

The method 200 continues at step 220 with determining that the front wheel 114 is rotationally locked. According to the current embodiment of method 200, determining that front wheel 114 is rotationally locked includes determining that front brake assembly 120 has been actuated to brake front wheel 114 based on a signal received from brake sensor 128.

In some embodiments or iterations of the method 200, determining that the front wheel 114 is rotationally locked may include actuating the front brake assembly 120 to rotationally lock the front wheel 114. Upon receiving an indication to change the overall length of the vehicle, in some cases, the vehicle control unit 180 may send a signal to the front brake assembly 120 to cause the assembly 120 to actuate to brake the front wheels 114. In this embodiment, the vehicle control unit 180 sends a signal to the front brake assembly 120 by sending a control signal to the brake fluid pump to actuate the front brake assembly 120 via the hydraulic lines. In some embodiments, it is contemplated that vehicle control unit 180 may be communicatively connected to an electromagnetic coil for electronically controlling the actuation of caliper 124 to brake front wheel 114.

In other embodiments, it is contemplated that determining that front wheel 114 is rotationally locked may further include detecting, by brake sensor 128, that front wheel 114 is not rotationally locked, and then subsequently actuating front brake assembly 120 to rotationally lock front wheel 114.

In some embodiments, the front wheels 114 may be rotationally locked by means other than the front brake assembly 120. For example, in some cases, the front wheel 114 may be locked by a locking pin received through a rim of the front wheel 114 and the front frame portion 114 or a bracket disposed around the front wheel 114. In some embodiments, automatic application of the front brake assembly 120 is not possible, for example, when the front brake assembly 120 can only be actuated by the brake lever 134. In either case of manually braking the front wheels 114 or rotationally locking the front wheels 114 by means other than the front brake assembly 120, after determining that the front wheels 114 are not rotationally locked, the method 200 may include providing an indication or instruction to the driver to rotationally lock the front wheels 114 before the method 200 may continue. Such instructions or commands to brake or rotationally lock front wheel 114 may include, but are not limited to, displaying a message or other visual indication to the driver, activating a sound, and/or causing a vibration of handlebar 132.

Once it is determined at step 220 that the front wheels 114 are locked, the method 200 then terminates at step 230, causing the motor assembly 170 to drive the rear wheels 154 such that the rear module 150 translates relative to the front module 110.

At step 230, when the indication received at step 210 corresponds to a request to increase the overall length of the vehicle 100, the vehicle control unit 180 causes the motor assembly 170 to back-drive the rear wheels 154 such that the rear module 150 translates rearward relative to the front module 110. By holding the front module 110 stationary, by braking the front wheels 114 by the front brake assembly 120 while back driving the rear module 150, the extension assembly 190 is extended and the overall length of the vehicle 100 is increased, i.e., the space between the front module 110 and the rear module 150 is increased. When the partially extended or extended position is reached (depending on the indication received at step 210), the extension sensor 198 senses that the desired position has been reached and sends a corresponding signal to the vehicle control unit 180. Based on the signal from the extension sensor 198, the vehicle control unit 180 then causes the motor assembly 170 to stop driving the rear wheels 154. In some cases, the vehicle control unit 180 then causes the extension lock 199 to lock the extension assembly 190 and causes the front brake assembly 120 to release the front wheel 114.

At step 230, when the indication received at step 210 corresponds to a request to reduce the overall length of the vehicle 100, the vehicle control unit 180 causes the motor assembly 170 to drive the rear wheels 154 forward such that the rear module 150 translates forward relative to and toward the front module 110. By holding the front module 110 stationary while driving the rear module 150 forward by braking the front wheels 114 by the front brake assemblies 120, the extension assembly 190 is caused to retract and the overall length of the vehicle 100 is reduced, i.e., the space 101 between the front module 110 and the rear module 150 is reduced. When the retracted or partially extended position is reached (depending on the indication received at step 210), the extension sensor 198 senses that the desired position has been reached and sends a corresponding signal to the vehicle control unit 180. Based on the signal from the extension sensor 198, the vehicle control unit 180 then causes the motor assembly 170 to stop driving the rear wheels 154. In some cases, the vehicle control unit 180 then causes the extension lock 199 to lock the extension assembly 190 and causes the front brake assembly 120 to release the front wheel 114.

In some embodiments or iterations, the method 200 may further include unlocking the left extension assembly 190 by a signal sent from the vehicle control unit 180 to the extension lock 199 prior to causing the motor assembly 170 to drive the rear wheels 154. In some cases, the left extension assembly 190 may be manually unlocked by an operator prior to the motor assembly 170 driving the rear wheels 154, rather than being automatically performed during the method 200. When unlocked, left extension assembly 190 can then be selectively extended and/or selectively retracted. When the selected position is reached, the extension assembly 190 is then locked, as described above. In embodiments having two extension assemblies including the extension lock 199, the vehicle control unit 180 may unlock the two extension assemblies 190. In some cases, the operator may alternatively manually unlock one or both extension assemblies 190. In such embodiments, the method 200 may further include providing an indication to the operator that one or both of the extension assemblies 190 need to be unlocked before the method 200 may continue.

In some embodiments, method 200 further includes determining that vehicle 100 is stationary prior to causing motor assembly 170 to drive rear wheels 154. In some such cases, the vehicle control unit 180 may receive a signal from the speed sensor 172 indicating that the vehicle 100 has zero speed in order to confirm that the vehicle 100 is not moving.

In some embodiments and/or iterations, method 200 may continue after causing motor assembly 170 to drive rear wheels 154, causing brake assembly 120 to release front wheels 114 to rotationally unlock front wheels 114. The vehicle 100 may then be driven or operated as usual by releasing the front wheels 114. In some embodiments, the operator can manually release the front wheel 114 via the brake lever 134 or the mode selector 185. In some embodiments, the vehicle control unit 180 may automatically cause the brake assembly 120 to release the front wheels 114 when movement of the rear module 150 is complete.

In some embodiments and/or iterations, method 200 may include receiving an indication from brake sensor 128 that front wheels 114 are no longer rotationally locked while rear wheels 154 are being driven to change the overall length of vehicle 100. In this case, the method may further include causing the motor assembly 170 to stop driving the rear wheels 154. In some embodiments, method 200 may further include providing an indication to the operator that front wheels 114 are unlocked and awaiting further action by the operator, and then continuing method 200 to resume causing motor assembly 170 to drive rear wheels 154.

In some embodiments and/or iterations, the method 200 may continue after causing the motor assembly 170 to drive the rear wheels 154, automatically causing the extension lock 199 to lock the left extension assembly 190. As described above, when the extension lock 199 has locked the extension assembly 190, the extension assembly 190 has a fixed length and resists changes in the overall length of the vehicle. In some embodiments and/or iterations, the extension lock 199 may be manually locked by an operator, rather than controlled during the method 200.

In embodiments where the vehicle 100 is a front wheel drive vehicle, it is contemplated that the method 200 may be adapted such that the vehicle control unit 180 determines that the rear wheels 154 are rotationally locked and then the vehicle control unit 180 causes the front wheels 114 to be driven such that the front module 110 translates relative to the rear module 150.

It is contemplated that method 200 may include additional or different steps for performing additional functions and/or performing the above-described steps.

FIG. 8 illustrates another embodiment of a vehicle 300 in accordance with the present technology. Elements of the vehicle 300 that are similar to elements of the vehicle 100 retain the same reference numerals and will generally not be described again.

The vehicle 300 includes a battery 340 connected to and supported by the rear frame portion 152. Therefore, the problem of transmitting power from the front module 110 to the rear module 150 is no longer present, because both the battery 340 and the motor assembly 170 are disposed in the rear module 150.

The position of the battery 340 when the vehicle 300 is in the retracted position is shown by outline 340'. The battery 340 is disposed at least partially under the seat 118 in at least one extended position, particularly a retracted position, of the front module 110 relative to the rear module 150.

Another embodiment of a vehicle 400 in accordance with the present technique is shown in fig. 9 and 10. Elements of the vehicle 400 that are similar to elements of the vehicle 100 retain the same reference numerals and will generally not be described again.

Similar to the vehicle 100 described above, the vehicle 400 includes a front module 410 and a rear module 450, the rear module 450 being selectively movably connected to the front module 410 such that a storage space 401 may be selectively defined in the vehicle 400.

In the vehicle 400, a seat 418 for the driver and a steering assembly 430 for steering the vehicle 400 are part of the rear module 450. Thus, as shown in fig. 10, the storage space 401 is formed in front of the seat 418, the steering assembly 430, and the mode selector 185 connected to the steering assembly 430. The storage space 401 is formed specifically between the seat 418 and the front wheel 114. The steering assembly 430 is operatively connected to the front wheels 114 and the front suspension assembly 116 by the extension assembly 190. Specifically, the steering assembly 430 controls steering of the front wheels 114 via a "by-wire" system, which is routed through a passage 197 of the left extension assembly 190. In various embodiments, different steering control systems may be utilized to control steering between the steering assembly 430 and the front wheels 114 on the rear module 450, including but not limited to a set of extendable mechanical linkages.

In this embodiment, the vehicle control unit 180 communicates with the motor assembly 170 through a wireless connection, as shown by the dashed line connection in fig. 10. It is contemplated that in some embodiments, the vehicle control unit 180 and the motor assembly 170 may have a hard-wired connection.
