Abstract

The invention relates to an electric automobile sliding prevention control method, a device, a system and a storage medium. The state of an electric automobile is monitored and comprises an accelerator signal, a speed signal, a brake signal and a gear signal of the electric automobile. Whether a sliding prevention signal is generated by triggering or not is judged according to the state. A motor of the electric automobile is controlled to work in a speed control mode if the sliding prevention signal is generated, the speed is preset to be 0, the pulse number of backward sliding of the electricautomobile within unit time serves as closed loop feedback, a closed loop preset value is 0, the difference value of the closed loop feedback value and the closed loop preset value is proportionallyadjusted and then overlaid on speed loop output, sliding prevention adjusting time is greatly shortened, and backward sliding distance is shortened.

Description

technical field [0001] The present invention relates to the technical field of electric vehicles, in particular to a slope-prevention control method, device, system and storage medium for an electric vehicle. Background technique [0002] At present, the problems of air pollution and resource depletion are becoming more and more prominent. Electric vehicles have the advantages of low noise, simple operation, energy saving and environmental protection, and become a new trend in the future automobile industry. When the car body is parked on a half slope, due to the weight of the car body, if the driver does not pull the handbrake in time, the car will accelerate and slide down under the action of gravity, which is an extremely unsafe factor. Based on the above background, most electric vehicle controllers provide the function of restraining the vehicle from rolling over half a slope. One of them is called creep function. When the accelerator of the car is not stepped on, the ...
