Detailed Description

The following discussion is directed to various embodiments of the disclosure. Although one or more of these embodiments may be preferred, the embodiments disclosed should not be interpreted, or otherwise used, as limiting the scope of the disclosure, including the claims. In addition, one skilled in the art will understand that the following description has broad application, and the discussion of any embodiment is meant only to be exemplary of that embodiment, and not intended to intimate that the scope of the disclosure, including the claims, is limited to that embodiment.

Vehicles, such as automobiles, trucks, sport utility vehicles, cross-over vehicles, minivans, boats, airplanes, all-terrain vehicles, recreational vehicles, or other suitable vehicles, typically include a steering system, such as an electric power steering system (e.g., which includes a steer-by-wire system or other electric power steering system) or other suitable steering system. The steering system may include a steering wheel that is not mechanically connected to the wheels, but controls the steering of the wheels using various motors and electrical signals based on input signals received from the steering wheel.

There is an increasing demand for vehicles (e.g., trucks, sport utility vehicles, etc.) having a high center of gravity. For example, operators are migrating to relatively tall ride vehicles (riding vehicles) to help improve the view of road and/or traffic conditions. However, such vehicles may be difficult to access, particularly for operators of such vehicles having mobility issues (e.g., elderly operators, operators having mobility-affecting conditions, etc.).

Typically, the operator of such a vehicle may use the steering wheel of the vehicle as a means of assisting in entering and/or exiting the vehicle. In a vehicle that includes a steering wheel mechanically connected to a steering system, a column lock may engage the steering wheel and hold the steering wheel stationary without the vehicle traveling. This resistance to movement allows the operator to enter or exit the vehicle using the steering wheel. However, in a steering system including a steer-by-wire system, such a column lock is not present to keep the steering wheel stationary. The challenge of entering and/or exiting the vehicle may prevent such operators from purchasing a high center of gravity vehicle with a steer-by-wire system.

Accordingly, there may be a need for systems and methods configured to provide entry and/or exit vehicle lift assistance, such as those described herein. In some embodiments, the systems and methods described herein may be configured to maintain the position of the steering wheel actuator as a means of entering and/or exiting the device using the steering wheel. The systems and methods described herein may be configured to provide entry assistance to an operator after a certain period of time.

In some embodiments, the systems and methods described herein may be configured to provide a counter-torque (e.g., using a steering wheel actuator or other suitable component of the steering system) that resists movement of the steering wheel in the direction of the torque applied by the operator in response to the operator applying a torque on the steering wheel (e.g., which applies a torque on the steering system).

In some embodiments, the systems and methods described herein may be configured to increase the counter torque in response to determining that the operator has applied torque on the steering wheel for a predetermined period of time (e.g., indicating that the operator has difficulty entering the vehicle), which may assist (e.g., or lift) the operator in entering the vehicle. It should be appreciated that the systems and methods described herein may be applied to any suitable application, including vehicles having relatively high ingress and/or egress locations (e.g., medium to heavy vehicles), vehicles having relatively low ingress and/or egress locations, or other suitable applications.

In some embodiments, the systems and methods described herein may be configured to provide greater reactive torque in response to a controller of the vehicle waking up, which may be detected over a suitable vehicle network (e.g., via door opening), such as the network described herein or other suitable network. The systems and methods described herein may be inactive during vehicle shutdown (e.g., departure from a vehicle).

In some embodiments, the systems and methods may determine whether the vehicle key is within a predetermined distance from the vehicle. The systems and methods described herein may be configured to provide entry assistance based on determining that a vehicle key is within a predetermined distance of the vehicle.

FIG. 1 generally illustrates a vehicle 10 according to the principles of the present disclosure. Vehicle 10 may include any suitable vehicle, such as a car, truck, sport utility vehicle, minivan, cross-over vehicle, any other passenger vehicle, any suitable commercial vehicle, or any other suitable vehicle. Although the vehicle 10 is illustrated as a passenger car having wheels and being used on a road, the principles of the present disclosure may be applied to other vehicles, such as airplanes, boats, trains, drones, or other suitable vehicles.

The vehicle 10 includes a vehicle body 12 and a hood 14. The passenger compartment 18 is at least partially defined by the vehicle body 12. Another portion of the vehicle body 12 defines an engine compartment 20. The hood 14 is movably attached to a portion of the vehicle body 12 such that the hood 14 provides access to the engine compartment 20 when the hood 14 is in a first or open position and the hood 14 covers the engine compartment 20 when the hood 14 is in a second or closed position. In some embodiments, the engine compartment 20 may be disposed at the rear of the vehicle 10 (as compared to what is generally shown).

The passenger compartment 18 may be disposed rearward of the engine compartment 20, but in embodiments where the engine compartment 20 is disposed in a rearward portion of the vehicle 10, the passenger compartment 18 may be disposed forward of the engine compartment 20. The vehicle 10 may include any suitable propulsion system, including an internal combustion engine, one or more electric motors (e.g., an electric vehicle), one or more fuel cells, a hybrid (e.g., a hybrid vehicle) propulsion system including a combination of an internal combustion engine, one or more electric motors, and/or any other suitable propulsion system.

In some embodiments, the vehicle 10 may include a gasoline engine or a gasoline-fueled engine, such as a spark-ignition engine. In some embodiments, the vehicle 10 may include a diesel fuel engine, such as a compression ignition engine. The engine compartment 20 houses and/or encloses at least some components of the propulsion system of the vehicle 10. Additionally or alternatively, propulsion control devices, such as an accelerator actuator (e.g., an accelerator pedal), a brake actuator (e.g., a brake pedal), a steering wheel (e.g., a steering wheel), and other such components, are disposed in the passenger compartment 18 of the vehicle 10. The propulsion control devices may be actuated or controlled by a driver of the vehicle 10 and may be directly correspondingly connected to corresponding components of the propulsion system, such as a throttle, a brake, an axle, a vehicle transmission, etc. In some embodiments, the propulsion control device may communicate signals to a vehicle computer (e.g., drive-by-wire), which in turn may control corresponding propulsion components of the propulsion system. As such, in some embodiments, the vehicle 10 may be an autonomous vehicle.

In some embodiments, the vehicle 10 includes a transmission in communication with the crankshaft via a flywheel or clutch or fluid coupling. In some embodiments, the transmission comprises a manual transmission. In some embodiments, the transmission comprises an automatic transmission. In the case of an internal combustion engine or hybrid vehicle, the vehicle 10 may include one or more pistons that operate in conjunction with a crankshaft to generate a force that is transmitted through a transmission to one or more axles, which turns the wheels 22. When the vehicle 10 includes one or more electric motors, the vehicle battery and/or fuel cell provides energy to the electric motors to rotate the wheels 22.

The vehicle 10 may include an automatic vehicle propulsion system, such as cruise control, adaptive cruise control, automatic brake control, other automatic vehicle propulsion systems, or a combination thereof. The vehicle 10 may be an automotive or semi-automotive vehicle, or other suitable type of vehicle.

The vehicle 10 may include a steering system, such as an Electric Power Steering (EPS) system. The EPS system may be configured to provide steering assistance to an operator of the corresponding vehicle. For example, an EPS system may be configured to apply an assist torque to an electric motor that is connected to a steering mechanism (such as a steering wheel). When the operator interacts with the steering wheel, the amount of force or torque exerted on the steering wheel by the operator is assisted by the electric motor (e.g., reducing the amount of force or torque required by the operator to perform a corresponding steering maneuver).

Typically, an EPS system communicates with one or more sensors configured to measure various aspects of the vehicle. The EPS system may communicate with one or more sensors using a vehicle communication system, such as a communication bus. The EPS system may communicate with one or more sensors using a vehicle communication system to receive various measurements from the one or more sensors. The EPS system may include a controller configured to determine an assist torque based on various measurements. The controller may then provide an assist torque to the electric motor to provide steering assistance to an operator of the vehicle.

In some embodiments, the steering system may include an electromagnetic torque superposition (MTO) system. An MTO system may include one or more gears and one or more integrated electromagnetic actuators. The MTO system may include pressure sensor hardware and a controller. The MTO may be configured to control increased and/or decreased torque applied to the steering system.

In some embodiments, the vehicle 10 may include an ethernet component 24, a Controller Area Network (CAN) bus 26, a media oriented system transfer component (MOST)28, a FlexRay component 30 (e.g., a brake-by-wire system, etc.), and a local interconnect network component (LIN) 32. The vehicle 10 may use the CAN bus 26, the MOST 28, the FlexRay component 30, the LIN 32, other suitable network or communication system, or a combination thereof to communicate various information from sensors, e.g., within or outside the vehicle, to various processors or controllers, e.g., within or outside the vehicle. The vehicle 10 may include additional features or fewer features than those generally shown and/or disclosed herein.

Fig. 2 generally illustrates a block diagram of an entry or exit assistance system 100 in accordance with the principles of the present disclosure. The system 100 may include a controller 102. The controller 102 may include a processor 104 and a memory 106. The processor 104 may include any suitable processor, such as those described herein. Additionally or alternatively, controller 102 may include any suitable number of processors in addition to processor 104 or in addition to processor 104. The memory 106 may comprise a single disk or multiple disks (e.g., hard drives), and includes a storage management module that manages one or more partitions within the memory 106. In some embodiments, the memory 106 may include flash memory, semiconductor (solid state) memory, or the like. The memory 106 may include Random Access Memory (RAM), Read Only Memory (ROM), or a combination thereof. The memory 106 may include instructions that, when executed by the processor 104, cause the processor 104 to provide at least entry and/or exit assistance to an operator of the vehicle 10.

In some embodiments, the system 100 includes a steering wheel actuator 108. Steering wheel actuator 108 may include any suitable actuator, and may include one or more actuators. The steering wheel actuator 108 may be configured to apply a torque to the steering wheel of the vehicle 10. The steering wheel actuator 108 may include or be in communication with one or more sensors configured to sense an amount of torque applied to the steering wheel of the vehicle 10 by an operator and/or to sense an amount of torque applied by the steering wheel actuator 108.

In some embodiments, the controller 102 may receive an incoming signal. The entry signal may include a voice command, proximity detection of an ignition key or key fob (key fob) associated with the vehicle 10, a door open signal, a wake-up signal associated with the CAN bus 26, any other suitable signal, or a combination thereof. The controller 102 may receive the entry signal from any suitable sensor of the vehicle 10. The entry signal may indicate that an operator of the vehicle 10 is attempting to enter the vehicle 10 on a side of the vehicle 10 corresponding to a steering wheel of the vehicle 10. The controller 102 may analyze the entry signal and may determine that an operator is attempting to enter the vehicle 10 based on the entry signal using any suitable technique.

The controller 102 may determine whether the entry signal indicates that an operator is attempting to enter or exit the vehicle 10 based on the entry signal. For example, the entry signal may indicate that the doors are open, but that the vehicle 10 has been previously fired open, thereby indicating that the operator is leaving the vehicle 10. If the controller 102 determines that the entry signal indicates that the operator is attempting to exit the vehicle 10, the controller 102 may selectively control the steering wheel actuator 108 to maintain the position of the steering wheel of the vehicle 10. It should be understood that the controller 102 may receive one or more ignition signals (e.g., from a sensor associated with ignition of the vehicle 10, from a controller or processor associated with ignition of the vehicle 10, or other suitable source). It should also be understood that the controller 102 may receive other suitable signals, information, and/or measurements that, individually or in combination, indicate that an operator is entering or exiting the vehicle 10.

Conversely, if the controller 102 determines that the entry signal indicates that the operator is attempting to enter the vehicle 10, the controller 102 identifies a steering wheel torque value corresponding to the torque applied to the steering wheel of the vehicle 10. The steering wheel torque value may correspond to an amount of torque applied to the steering wheel by an operator while the operator is attempting to enter the vehicle 10 (e.g., by pulling the steering wheel to assist in entering the vehicle 10). Controller 102 may determine a counter torque value corresponding to the steering wheel torque value. For example, the controller 102 may identify a torque value that is opposite the steering wheel torque value (e.g., to oppose the steering wheel torque value).

Controller 102 may apply torque to the steering wheel based on the reactive torque value. For example, the controller 102 may selectively instruct the steering wheel actuator 108 to generate a torque corresponding to the reactive torque value. Steering wheel actuator 108 may apply a torque to the steering wheel of vehicle 10. The torque corresponding to the reaction torque value may oppose the steering wheel torque value, which may maintain the position of the steering wheel when the operator attempts to enter the vehicle 10.

Controller 102 may monitor the steering wheel torque value for a period of time. For example, the controller 102 may wait a predetermined period of time. After the predetermined period of time expires, the controller 102 may receive a steering wheel torque value. The controller 102 determines whether to apply a steering wheel torque value (which may include, for example, a steering wheel torque value or a torque value substantially similar to the steering wheel torque value) to the steering wheel after expiration of the predetermined period of time. If controller 102 determines that the steering wheel torque value is to be applied to the steering wheel after the predetermined period of time has expired, controller 102 may adjust the reactive torque value. For example, the controller 102 may increase the reactive torque value. Controller 102 may increase the reaction torque value by any suitable amount. For example, the controller 102 may determine a percentage of the steering wheel torque value applied to the steering wheel. Controller 102 may increase the counter torque value by a percentage (e.g., controller 102 may increase the absolute value of the counter torque value by a greater amount for larger values of steering wheel torque than for smaller values of steering wheel torque). Alternatively, the controller 102 may decrease the reactive torque value. The controller 102 may selectively instruct the steering wheel actuator 108 to apply torque to the steering wheel based on the adjusted reactive torque value, which may overcome the steering wheel torque value and assist (e.g., by pulling away from the operator) the operator in entering the vehicle.

In some embodiments, controller 102 may determine that the steering wheel torque value has increased. For example, controller 102 may monitor a steering wheel torque value. If controller 102 determines that the steering wheel torque value has increased (e.g., at any time during the predetermined period or after its expiration), controller 102 may selectively adjust the counter torque value. For example, controller 102 may increase the reaction torque value to be equal to or greater than the steering wheel torque value. Controller 102 may then selectively control steering wheel actuator 108 based on the adjusted reactive torque value.

In some embodiments, the controller 102 may determine whether the steering wheel torque value is no longer applied to the steering wheel of the vehicle 10. For example, the controller 102 may receive a steering wheel torque value indicating that the operator has released his steering wheel. Controller 102 may selectively control steering wheel actuator 108 to maintain the position of the steering wheel of vehicle 10 in any suitable position.

In some embodiments, the controller 102 may detect a first torque value corresponding to a first torque applied to the steering wheel in response to an entry signal indicating that the operator door is open. The controller 102 may determine a second torque value corresponding to the first torque value. The absolute value of the second torque value may be equal to the absolute value of the first torque value. The second torque value may be applied in the opposite direction of the first torque value.

The controller 102 may apply a second torque corresponding to the second torque value to the steering wheel. The controller 102 may determine whether to selectively adjust the second torque value based on at least one of measurements associated with seat sensors of the vehicle 10 and a predetermined period of time. The seat sensor may comprise any suitable seat sensor. The seat sensor may be disposed in an operator seat of the vehicle 10. The seat sensor may be configured to measure a force acting on the operator seat. The force may indicate whether the operator is in the operator's seat. For example, if the force is greater than the seat sensor threshold, the force may indicate that the operator is on the operator seat. Alternatively, if the force is less than the seat sensor threshold, the force may indicate that the operator is not present or partially not present on the operator seat.

In some embodiments, the controller 102 may determine to selectively adjust the second torque value in response to the force measured by the seat sensor being less than the seat sensor threshold and a period of time associated with the first torque being applied to the steering wheel being greater than a predetermined period of time (e.g., indicating that the operator is not in the operator seat and is still applying the first torque or substantially the first torque to the steering wheel). For example, the controller 102 may increase the second torque value such that when it is applied to the steering wheel actuator 108, the steering wheel moves in a direction opposite the first torque to assist the operator in entering the vehicle 10. The controller 102 may apply a second torque corresponding to the second torque value to the steering wheel actuator 108.

Additionally or alternatively, the controller 102 may determine to selectively adjust the second torque value in response to the force measured by the seat sensor being greater than a seat sensor threshold and a period of time associated with the first torque being applied to the steering wheel being less than a predetermined period of time (e.g., indicating that the operator is in the operator's seat and is no longer applying torque to the steering wheel). For example, the controller 102 may decrease the second torque value such that the steering wheel is held in place when it is applied to the steering wheel actuator 108. The controller 102 may apply a second torque corresponding to the second torque value to the steering wheel actuator 108.

Additionally or alternatively, the controller 102 may determine to selectively adjust the second torque value in response to the force measured by the seat sensor being greater than a seat sensor threshold and a period of time associated with the first torque being applied to the steering wheel being greater than a predetermined period of time (e.g., indicating that the operator is in the operator's seat and is applying torque to the steering wheel). For example, the controller 102 may decrease the second torque value such that the steering wheel is held in place when it is applied to the steering wheel actuator 108. The controller 102 may apply a second torque corresponding to the second torque value to the steering wheel actuator 108.

In some embodiments, the controller 102 may receive an ignition signal, as described. The controller 102 may detect a third torque value corresponding to a third torque applied to the steering wheel in response to the ignition signal indicating that the ignition state has changed from the on position to the off position and in response to the entry signal indicating that the operator door is open (e.g., indicating that the operator is leaving the vehicle 10). The controller 102 may determine a fourth torque value corresponding to the third torque value. The controller 102 may apply a fourth torque to the steering wheel actuator 108 that corresponds to the fourth torque value (e.g., in a direction opposite the third torque value such that the steering wheel is held in place while the operator attempts to exit the vehicle 10).

In some embodiments, the controller 102 may not determine to selectively adjust the fourth torque value in response to the force measured by the seat sensor being greater than the seat sensor threshold and a period of time associated with the third torque being applied to the steering wheel being greater than a predetermined period of time (e.g., indicating that the operator is in the operator's seat and applying the third torque to the steering wheel, which may indicate that the operator is difficult to exit the vehicle 10). The controller 102 may not adjust the fourth torque value to prevent the operator from accidentally or undesirably moving out of the operator's seat.

In some embodiments, the controller 102 may determine to selectively adjust the fourth torque value in response to the force measured by the seat sensor being greater than the seat sensor threshold and a period of time associated with the third torque being applied to the steering wheel being greater than a predetermined period of time (e.g., indicating that the operator is in the operator's seat and applying the third torque to the steering wheel, which may indicate that the operator is having difficulty exiting the vehicle 10). The controller 102 may adjust the fourth torque value such that, when applied to the steering wheel actuator 108, the steering wheel moves in a direction suitable to assist the operator in moving away from the vehicle 10 (e.g., in the same direction as the third torque value). The controller 102 may adjust the fourth torque value in a manner similar to that described with respect to the second torque value. The controller 102 may apply an adjusted torque value corresponding to the adjusted fourth torque value to the steering wheel actuator 108. In some embodiments, the controller 102 may indicate to the operator that the steering wheel will assist the operator in moving away from the vehicle 10 before applying the adjusted torque value corresponding to the adjusted fourth torque value to the steering wheel actuator 108. For example, the controller 102 may cause actuation of the steering wheel using the steering wheel actuator 108 in a mode that indicates that the steering wheel will assist the operator. Additionally or alternatively, the controller 102 may cause an audible indication, a visual indication, other tactile or haptic indication, other suitable indication, or a combination thereof.

Additionally or alternatively, the controller 102 may determine to selectively adjust the fourth torque value in response to the force measured by the seat sensor being less than the seat sensor threshold and a period of time associated with the third torque being applied to the steering wheel being greater than a predetermined period of time (e.g., indicating that the operator is not in the operator's seat and the third torque is being applied to the steering wheel, which may indicate that the operator has left the vehicle 10). For example, the controller 102 may decrease the fourth torque value such that the steering wheel is held in place when it is applied to the steering wheel actuator 108. The controller 102 may apply a fourth torque corresponding to the fourth torque value to the steering wheel actuator 108.

In some embodiments, the system 100 and/or the controller 102 may perform the methods described herein. However, the methods described herein as being performed by the system 100 and/or the controller 102 are not meant to be limiting, and thus any type of software executing on the controller is capable of performing the methods described herein without departing from the scope of the present disclosure. For example, a controller (e.g., a processor executing software within a computing device) may perform the methods described herein.

Fig. 3 is a block diagram generally illustrating a lift assistance method 200 in accordance with the principles of the present disclosure. At 202, at least one door of the vehicle 10 is opened. The method 200 may include waking up in response to at least one door opening.

At 204, the method 200 may enable the enter and/or exit functionality. For example, the controller 102 may begin monitoring and/or setting the status and/or values of various flags. The controller 102 may monitor or set the door open wake state flag. For example, the controller 102 may set the door open wake state flag to true. The door open wake state flag may be set to true by the controller 102 or other suitable controller in response to at least one door being open. The controller 102 may set a flag enabled from the sleep state to true in response to enabling the enter and/or exit functionality. The controller 102 may monitor the ignition status value and the seat occupancy value. Additionally or alternatively, the controller 102 may monitor the amount of torque applied to the steering wheel using sensors associated with the steering wheel actuator 108. The controller 102 may determine whether the amount of torque is greater than a threshold calibrated amount of torque.

At 206, method 200 may receive a large steering wheel torque value. For example, the controller 102 may determine that the amount of torque applied to the steering wheel is greater than a threshold calibrated amount of torque (e.g., this may be referred to as a large steering wheel torque). As described, the controller 102 may apply various amounts of torque to the steering wheel actuator 108 to assist the operator in entering the vehicle 10. The seat occupancy value may be set to "ON" in response to an operator being ON the operator seat. As described, the controller 102 may apply a torque to the steering wheel actuator 108 to hold the steering wheel in place.

At 208, the method 200 may include detecting that the ignition status value is set to "on," which indicates that the operator has initiated ignition. The controller 102 may resume normal operation (e.g., interrupt the enter and/or exit functions) in response to the ignition status value being set to "on".

Fig. 4 is a flow chart generally illustrating a lift assistance method 300 in accordance with the principles of the present disclosure. At 302, the method 300 receives an incoming signal. For example, the controller 102 receives an incoming signal.

At 304, method 300 identifies a steering wheel torque value. For example, the controller 102 identifies a steering wheel torque value applied to the steering wheel by the operator. Controller 102 may receive the steering wheel torque value from a sensor associated with steering wheel torque actuator 108 or any suitable sensor or source.

At 306, the method 300 determines whether the entry signal indicates that an operator is attempting to enter the vehicle. For example, the controller 102 determines whether the entry signal indicates that an operator is attempting to enter the vehicle 10 on a side of the vehicle 10 associated with the steering wheel. If the controller 102 determines that the entry signal does not indicate that an operator is attempting to enter the vehicle 10, the method 300 continues at 316. If the controller 102 determines that the entry signal indicates that an operator is attempting to enter the vehicle 10, the method 300 continues at 308.

At 308, method 300 determines a reactive torque value. For example, the controller 102 determines a reaction torque value corresponding to the amount of torque that will be opposite the steering wheel torque value.

At 310, method 300 applies a torque to the steering wheel corresponding to the counter-torque value. For example, the controller 102 applies a torque corresponding to the reaction torque value to the steering wheel using the steering wheel actuator 108. The torque corresponding to the counter-torque value, when applied by the steering wheel actuator 108, may oppose the steering wheel torque value, which may hold the steering wheel in place.

At 312, method 300 determines whether torque applied to the steering wheel has been applied to the steering wheel for a predetermined period of time. For example, the controller 102 determines whether a torque corresponding to the steering wheel torque value has been applied to the steering wheel for a predetermined period of time. If the controller 102 determines that a torque corresponding to the steering wheel torque has been applied to the steering wheel for at least the predetermined period of time, the method 300 continues at 314. If the controller 102 determines that a torque corresponding to the steering wheel torque value has not been applied to the steering wheel for at least the predetermined period of time, the method 300 continues at 316.

At 314, method 300 adjusts the reactive torque value and applies torque to the steering wheel based on the adjusted reactive torque value. For example, the controller 102 may increase (e.g., or decrease) the counter-torque value. Controller 102 may selectively control steering wheel actuator 108 to apply a torque corresponding to the adjusted reactive torque value to the steering wheel of vehicle 10. The method 300 continues at 312.

At 316, method 300 applies the steering wheel position holding torque. For example, the controller 102 may selectively control the steering wheel actuator 108 such that the steering wheel actuator 108 applies a torque to the steering wheel to maintain the steering wheel position in place.

Fig. 5 is a flow diagram generally illustrating an alternative lift assistance method 400 in accordance with the principles of the present disclosure. At 402, the method 400 receives an incoming signal. For example, the controller 102 may receive an entry signal in response to an operator door opening.

At 404, method 400 detects a first torque value corresponding to a first torque applied to the steering wheel. For example, the controller 102 may use a sensor associated with the steering wheel actuator 108 to detect a first torque value corresponding to a first torque applied to the steering wheel.

At 406, the method 400 determines a second torque value corresponding to the first torque value. For example, the controller 102 may determine a second torque value corresponding to the first torque value.

At 408, method 400 applies a second torque to the steering wheel corresponding to the second torque value. For example, the controller 102 may apply a second torque corresponding to the second torque value to the steering wheel using the steering wheel actuator 108.

At 410, the method 400 receives at least one measurement associated with a seat sensor. For example, the controller 102 may receive at least one measurement associated with a seat sensor.

At 412, method 400 determines whether to selectively adjust the second torque value based on at least one of a measurement associated with the seat sensor and a period of time associated with the first torque being applied to the steering wheel. For example, the controller 102 may determine whether to selectively adjust the second torque value based on at least one of a measurement associated with a seat sensor and a period of time associated with the first torque being applied to the steering wheel.

At 414, method 400 applies an adjusted torque corresponding to the adjusted second torque value to the steering wheel in response to determining to selectively adjust the second torque value. For example, controller 102 may apply an adjusted torque corresponding to the adjusted second torque value to the steering wheel using steering wheel actuator 108 in response to determining to selectively adjust the second torque value.
