Embodiment

[0040] This embodiment provides a slope prevention control method for hill start. This embodiment provides the operation steps of the method as described in the flow chart, but more or fewer operation steps may be included based on routine or non-creative work. The sequence of steps enumerated in the embodiments is only one of the execution sequences of many steps, and does not represent the only execution sequence. refer to figure 1 , the slope start prevention slope control method of the present embodiment includes the following steps:

[0041] S1. When the gradient of the ramp where the vehicle is located is less than the preset gradient, obtain the braking information of the brake pedal, and judge whether the brake pedal has reached the timing to start releasing according to the braking information;

[0042] Specifically, according to the opening degree of the brake pedal, the timing when the brake pedal is switched from the pressed state to the released state is taken as...

Abstract

The invention discloses an anti-slide control method, device, equipment and storage medium for starting on a slope, and relates to the technical field of vehicle control. The present invention recognizes the timing when the brake pedal is released, and during the unloading of the braking force, the driving force starts to output. Compared with the prior art, the present invention is more intelligent, and the driving force is output in advance before the vehicle slips backwards, so that the sum of the output driving force and the braking force maintains a balance with the slope resistance, which can effectively prevent the vehicle from falling behind the slope. Slip occurs; moreover, the control method of the present invention does not need to keep outputting a certain driving force during braking, which can effectively avoid energy waste and avoid the possibility of overheating of the power source. The anti-slipping device for starting on a slope according to the present invention is based on the independent development platform of the VCU, and can be realized by setting a calculation module in the application layer software, without adding additional components, and the development cost is relatively low.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, in particular to a method, device, equipment and storage medium for controlling a slope start and anti-slip slope. Background technique [0002] With the development of electronic technology, electronic control systems have been applied to various fields of vehicles. At present, vehicles are generally equipped with many auxiliary driving functions, such as HHC (Hill-start Hold Control, hill-start assist control), HDC (Hill Descent Control, slope descent control), AVH (Automatic Vehicle Hold, automatic parking control) and other functions make vehicle driving more convenient and safer. Among them, the HHC hill start assist control function, the principle is that after the driver releases the brake pedal, the system continues to maintain the brake pressure generated by depressing the brake pedal for a certain period of time, giving the driver time to leave the brake and step on the ...
