Problems solved by technology

If the car slides downhill, it will cause the engine to stall, shake when starting, and the ride comfort will be poor. If it is serious, it will cause traffic accidents such as collision with the rear car
Some experienced drivers usually use the clutch semi-linkage control method to avoid the vehicle's slippery slope, but this method has high requirements for the driver's operation, and the driver needs to judge the different slopes and vehicle loads. Can't completely avoid car slippery slope
In addition, the slippery slope is likely to cause the driver's panic, leading to more unpredictable safety hazards
[0003]The current slope stabilization control method has the problems of parking on a slope and starting on a slope.

Embodiment Construction

[0051] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0052] In one embodiment, such as figure 1 As shown, a slope stabilization control method is provided. In this embodiment, the method is applied to an engine control unit for illustration. It can be understood that this method can also be applied to an electronic handbrake system, and can also be applied to The vehicle control system of the electronic handbrake system is implemented through the interaction between the engine control unit and the electronic handbrake system. In this embodiment, the method includes the following steps:

[0053] Step 102, obtaining the dura...

Abstract

The invention relates to a slope stabilizing control method and device, computer equipment and a storage medium. The method comprises the steps that the slope stabilizing duration of a vehicle in a slope stabilizing state is obtained, the slope stabilizing torque of the vehicle in the slope stabilizing state is obtained, and the accelerator opening degree of the vehicle is obtained; if the slope stabilizing duration exceeds the preset duration and the accelerator opening degree of the vehicle is smaller than the accelerator opening degree threshold value, an electronic hand brake of the vehicle is controlled to be started, and the slope stabilizing torque of the vehicle is controlled to be gradually reduced to 0; the accelerator opening degree of the vehicle is continuously obtained, and if the accelerator opening degree of the vehicle is not smaller than the accelerator opening degree threshold value, the total output torque of the vehicle is obtained; and if the total output torque of the vehicle is larger than the slope stabilizing torque, an electronic hand brake of the vehicle is controlled to be closed. By the adoption of the method, the purposes of preventing slope sliding during slope parking and improving slope starting stability can be achieved.

Description

technical field [0001] The present application relates to the technical field of vehicle control, in particular to a slope stabilization control method, device, computer equipment and storage medium. Background technique [0002] With the development of automobile technology, the requirements for the safety and reliability of automobiles are getting higher and higher. Parking brake technology is a braking technology that can prevent the car from slipping due to temporary or long-term parking on a certain slope. The car of the manual air pressure braking system used on the automobile of the related art usually has the phenomenon of sliding when starting on a slope. caused by power interruption. If the car slides downhill, it will cause the engine to stall, shake when starting, and the ride comfort will be poor, and if it is serious, it will cause traffic accidents such as collision with the rear car. Some experienced drivers usually use the clutch semi-linkage control meth...
