Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Fig. 1 is a flowchart of a control method for an electric vehicle according to an embodiment of the present invention, where the present embodiment is applicable to a case where the electric vehicle is controlled to enter a push mode, and the method may be executed by the electric vehicle, where the electric vehicle includes a control module, a speed regulation module, a mode switching module, and an execution module, and the control method for the electric vehicle specifically includes the following steps:

s100: controlling the electric vehicle to be in a starting state;

the starting state refers to that the whole electric vehicle is electrified, namely the whole electric vehicle is in the starting state after being electrified.

S200: the control module judges whether the type of the trigger signal received by the mode switching module is a first type of trigger signal, a set voltage signal is output by a rotating signal output end of the speed regulating module, and the electric vehicle is in a runaway protection mode; if yes, executing S300; if not, executing S100. And in the runaway protection mode, the operation signal input by the speed regulation module is invalid by the user.

The control module may be a controller, and the mode switching module may be a module for controlling speed gear or power gear adjustment of the electric vehicle, and may be, for example, a button, and may be a touch screen. The speed regulating module is used for regulating the speed, and can comprise a rotating handle, and the speed is regulated according to the rotating angle of the rotating handle. The execution module may be a motor.

Optionally, the first type of trigger signal is a long press. For example, when the mode switching module is a touch button, the first type of trigger signal may be a long press, and the user presses the mode switching module for a long time, so that the mode switching module receives the first type of trigger signal. When the speed regulating module comprises a rotating handle, each rotating angle of the rotating handle corresponds to a voltage value, the speed regulating module outputs the corresponding voltage value according to the rotating angle, and the voltage value corresponding to the rotating handle can be set when the voltage signal is rotated to the maximum angle. Under the protection mode of the runaway, the operation signal input by the speed regulation module is invalid, so that the situation that a user mistakenly operates the speed regulation module to cause the motor of the electric vehicle to rotate, the vehicle is out of control and a safety accident is caused can be prevented. For example, when the electric vehicle is in a pause state, the user mistakenly operates the speed regulation module, so that the execution module drives the electric vehicle to accelerate, and the vehicle suddenly loses control and accelerates. After the electric vehicle enters the galloping protection mode, the operation signal input by the speed regulation module is invalid, and even if a user mistakenly operates the speed regulation module, the execution module cannot drive the electric vehicle to suddenly accelerate, so that the safety of the user is protected.

S300: the control module controls the execution module to drive the electric vehicle to enter a pushing mode; in the pushing mode, the electric vehicle accelerates to a set speed at a set acceleration.

The control module receives a trigger signal of which the type received by the switching module is the first type, the rotating signal output end of the speed regulating module outputs a set voltage signal, and the electric vehicle is in an galloping protection mode, the control module controls the execution module to drive the electric vehicle to enter a pushing mode. For example, when the point touch button is continuously pressed by external force, the rotating handle rotates to the maximum angle, and the electric vehicle is in the vehicle protection mode, the control module controls the execution module to drive the electric vehicle to enter the pushing mode. In the push mode, the electric vehicle accelerates to a set speed at a set acceleration, illustratively, the set speed can be 5km/h, and in the push mode, the speed of the electric vehicle is low, so that safety accidents caused by overlarge speed are avoided. And in the pushing mode, the control module controls the current of the electric vehicle to be the maximum value in the allowable range, so that the electric vehicle still has larger driving force at low speed, and the electric vehicle has a better function of assisting pushing.

The embodiment provides an electric vehicle and a control method thereof, wherein the electric vehicle comprises a control module, a speed regulation module, a mode switching module and an execution module. According to the control method of the electric vehicle, on the basis of the existing devices of the electric vehicle, when the type of the trigger signal received by the mode switching module is the first type of trigger signal, the rotation signal output end of the speed regulating module outputs the set voltage signal, and the electric vehicle is in the runaway protection mode, the control module controls the electric vehicle to enter the push mode, namely controls the electric vehicle to accelerate to the set speed at the set acceleration, so that the electric vehicle can still have larger driving force at low speed even in a road section where the electric vehicle cannot be ridden, and the function of assisting a user to push is achieved. The pushing mode is realized on the premise that the electric vehicle is in the runaway protection mode, runaway caused by misoperation of the speed regulation module can be avoided, and safety of a user is guaranteed. The control method of the electric vehicle is completely realized by depending on the existing speed regulating module, mode switching module and control module of the electric vehicle, and other devices are not required to be additionally arranged, so that the cost of the electric vehicle is lower, and the control method is easy to realize.

Fig. 2 is a schematic structural diagram of another electric vehicle according to an embodiment of the present invention, and referring to fig. 2, on the basis of the above embodiment, optionally, the electric vehicle further includes a brake module, an input end of the brake module is electrically connected to a sixth end of the control module, and an output end of the brake module is electrically connected to a seventh end of the control module; the sixth end of the control module outputs a fixed level signal;

the control method of the electric vehicle specifically comprises the following steps:

s100: controlling the electric vehicle to be in a starting state;

s101: the control module controls the electric vehicle to enter a runaway protection mode when the signal output by the output end of the brake module is opposite to the level signal output by the sixth end of the control module and the wheel movement signals output by the wheel movement output end of the execution module within a first set time or longer are all smaller than a set threshold value.

The level signal output by the sixth end of the control module is a fixed signal, which may be a high level or a low level, and this embodiment is not limited in this embodiment. Optionally, the braking module may include a left braking cable and a right braking cable, and when a user pinches at least one of the left braking cable and the right braking cable, a signal output by the output end of the braking module is the same as a level signal output by the sixth end of the control module; when a user does not pinch the left brake cable and the right brake cable, the signal output by the output end of the brake module is opposite to the level signal output by the sixth end of the control module.

The rotation signal can be a voltage signal, when the execution module is a motor, different rotating speeds of the motor correspond to different voltage values, and the larger the rotating speed is, the larger the voltage value is. The wheel movement signal being smaller than the set threshold value may indicate that the rotation speed of the electric vehicle is smaller than the set speed threshold value. The first set time may be 3 s. And controlling the electric vehicle to enter an overtaking protection mode when the rotating speed of the electric vehicle is less than the set speed threshold value within 3s or more than 3s after the brake module does not receive the brake signal. The speed threshold value can be set according to the age of the user, the riding habit of the user and the like. When a user pinches at least one of the left brake cable and the right brake cable and the rotating speed of the motor is smaller than a set speed threshold value, the electric vehicle is controlled to enter a runaway protection mode.

S200: the control module judges whether the type of the trigger signal received by the mode switching module is a first type of trigger signal, a set voltage signal is output by a rotating signal output end of the speed regulating module, and the electric vehicle is in a runaway protection mode; if yes, executing S300; if not, executing S100.

S301: the control module controls the electric vehicle to enter a riding mode within a first set time from the moment when the received signal output by the output end of the brake module and the received signal output by the sixth end of the control module are changed from the same signal to different signals;

and in the riding mode, the control module controls the execution module to adjust the speed of the electric vehicle according to a signal output by the rotation signal output end of the speed adjusting module.

The threshold value is set to be a voltage value, and a user can set the threshold value according to requirements.
