Embodiment 1

[0038] see figure 1 , the anti-slope method of the electric vehicle according to the embodiment of the present invention, the method comprises the steps:

[0039] S01: When it is detected that the electric vehicle is in a rolling state, the rolling direction of the electric vehicle is obtained, and the rolling distance of the electric vehicle is obtained in real time;

[0040] S02: Determine the rotation direction of the motor of the electric vehicle according to the rolling direction;

[0041] S03: Determine the duty cycle of the motor according to the sliding distance;

[0042] S04: Generate a rotation control command according to the duty cycle and the rotation direction, and send the control command to the drive module, so that the drive module controls the motor to rotate.

[0043] In the embodiment of the present invention, when it is detected that the electric vehicle is in a rolling state. For example, when the electric vehicle stops in the process of going uphill, ...

Embodiment 2

[0058] Furthermore, when the accelerator value of the electric vehicle is zero, the mechanical brake does not work, and the motor rotor position detection sensor detects a signal change, the electric vehicle enters a rolling state.

[0059] In this embodiment, when the accelerator value of the electric vehicle is zero, the mechanical brake does not work, and the motor rotor position detection sensor detects a signal change, the electric vehicle enters a rolling state. That is to say, when the above three conditions are satisfied, the electric vehicle will enter the rolling state. When only one of the above three is satisfied, or only two of them are satisfied, the electric vehicle will not enter the rolling state.

[0060] If the electric vehicle accelerator value is not zero, it means that the electric vehicle has power, which means that the electric vehicle is driving, so the electric vehicle does not need to enter the rolling state. When the throttle value of the electric ...

Embodiment 3

[0066] see figure 2 , further, including steps in step S01:

[0067] S011: obtain the signal change detected by the motor rotor position detection sensor in real time;

[0068] S012: Determine the rolling distance and rolling direction of the electric vehicle according to the signal change.

[0069] In this embodiment, the position detection sensor can determine the rolling distance and rolling direction of the electric vehicle according to the detected signal changes, and the structure is simple and easy to implement.

[0070] Among them, different types of position detection sensors have different types of detected signals. For details, reference may be made to the working principle of the position detection sensor in the first embodiment. I won't go into details here.

Abstract

The present invention is applicable to the technical field of electric vehicles, and provides an electric vehicle anti-slope method and device, an electric vehicle and a computer-readable storage medium. The electric vehicle anti-slope method includes: , obtain the rolling direction of the electric vehicle, and obtain the rolling distance of the electric vehicle in real time; determine the rotation direction of the motor of the electric vehicle according to the rolling direction; determine the duty cycle of the motor according to the rolling distance; according to the duty cycle and the direction of rotation Generate a rotation control instruction, and send the control instruction to the drive module, so that the drive module can control the rotation of the motor. In the embodiment of the present invention, the electric vehicle will continue to work according to the control command, so as to prevent the electric vehicle from slipping again. The occurrence of hidden dangers makes electric vehicles safer.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a method and device for preventing slopes of an electric vehicle, an electric vehicle and a computer-readable storage medium. Background technique [0002] With the popularization of new energy and motor control technology, electric vehicles have been widely used in many fields, such as electric motorcycles, riding lawn mowers, floor washing robots, etc. However, when the electric vehicle is going uphill or downhill, when it needs to stay on the slope, due to inertia and its own gravity, the electric vehicle will automatically move down, that is, the phenomenon of slippage occurs, which will lead to Electric vehicles cannot be parked on the slope, and secondly, there will be certain safety hazards. For example, if there are other vehicles or pedestrians under the ramp, the electric vehicle may collide with the vehicles or pedestrians under the ramp, thereby ...
