Embodiment 1

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

[0039] S01: When the electric vehicle is detected to be in a rolling state, obtain the rolling direction of the electric vehicle and obtain the rolling distance of the electric vehicle 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 for the drive module to control the rotation of the motor.

[0043] In the embodiment of the present invention, when it is detected that the electric vehicle is in a slipping state. For example, when an electric vehicle stops while going uphill, the electric vehicle appears to ret...

Embodiment 2

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

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

[0060] The throttle value of the electric vehicle is not zero, which 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 state of rolling. When the throttle ...

Embodiment 3

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

[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 has a simple structure and is easy to implement.

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

Abstract

The invention is applicable to the technical field of electric vehicles, and provides an anti-slip method and a device for an electric vehicle, the electric vehicle and a computer readable storage medium. The anti-slip method for the electric vehicle comprises the steps that when it is detected that the electric vehicle is in a slip state, the slip direction of the electric vehicle is obtained, and the slip distance of the electric vehicle is obtained in real time; the rotating direction of a motor of the electric vehicle is determined according to the sliding direction; the duty ratio of themotor is determined according to the vehicle sliding distance; and a rotation control instruction is generated according to the duty ratio and the rotation direction, and the control instruction is sent to the driving module so that the driving module can control the motor to rotate. In the method of the invention, the electric vehicle can continuously work according to the control instruction, sothat the phenomenon that the electric vehicle slides again is prevented, that is, the position of the electric vehicle can be kept unchanged, potential safety hazards caused by sliding of the electric vehicle can be prevented, and the electric vehicle is safer.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a slope prevention method and device for electric vehicles, 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, and washing robots. 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 downward, that is, the phenomenon of sliding downhill, which will lead to Electric vehicles cannot park on slopes, and secondly, there will be certain safety hazards. For example, if there are other vehicles or pedestrians below the ramp, electric vehicles may crash into vehicles or pedestrians below the ramp, causing safety accidents. [000...
