Standing slope control method and device

Abstract

The invention relates to the technical field of vehicles, and provides a method and device for controlling a standing slope. The slope control method of the present invention includes: judging whether the motor speed direction of the vehicle is consistent with the demand direction corresponding to the current gear position, if not, starting the timing; after starting the timing, judging whether the motor speed is greater than or equal to the preset Slope threshold, if it is, then it is determined that the vehicle has a slope; and according to the first time and the motor speed between starting the timing to determine that the vehicle occurs, the braking torque required for the motor to realize the slope is determined, and according to the first The time and the braking torque set the electrical angle of the motor's descent so that the electric motor is able to stop the vehicle when the electrical angle of the electrical motor of the descent is reached. The solution of the present invention can simply and reliably realize the anti-slope function when the vehicle has no ESP or the ESP has no uphill assist function, and ensures that the slope distance is small and the slope process is stable.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method and device for controlling a standing slope. Background technique [0002] When the vehicle goes uphill, if the accelerator is not stepped on, the vehicle will slide downhill. In this regard, some models in the prior art realize the "anti-slope function" by adopting the uphill assistance function of ESP (Electronic Stability Program, vehicle body electronic stability system). [0003] However, due to the consideration of various factors such as vehicle cost, application and model, there are still many types of electric vehicles that are not equipped with ESP or equipped with ESP that has no uphill assist function, which is easy to cause slippery slopes when advancing on a slope. And a traffic accident occurs. In addition, even for electric vehicles with the uphill assist function of ESP, the implementation process of the existing "anti-slope function" is relatively co...
