Parking control method and device, computer equipment and storage medium

Abstract

The invention relates to a parking control method and device, computer equipment and a storage medium. The method comprises the steps that the brake opening degree and the accelerator opening degree of a vehicle are obtained, and whether the vehicle is in a slope sliding prevention state or not is determined according to the brake opening degree and the accelerator opening degree; if the vehicle is in the anti-slope-sliding state, anti-slope-sliding torque is obtained, and the output torque of a driving motor of the vehicle is controlled to be gradually increased to the anti-slope-sliding torque; the duration of the vehicle in the slope sliding prevention state is obtained, and whether the vehicle is in the required parking state or not is determined according to the brake opening degree, the accelerator opening degree and the duration; if the vehicle is in the required parking state, the pressure of a parking air chamber of the vehicle is obtained, and connection and disconnection of a pressure reducing valve of an electronic hand brake system of the vehicle are controlled according to the anti-slope-sliding torque and the pressure of the parking air chamber; and if the pressure of the parking air chamber is lower than the parking pressure threshold value, the output torque of a driving motor of the vehicle is controlled to be gradually reduced to 0 from the anti-slope-sliding torque. By the adoption of the method, the beneficial effects of preventing slope sliding during slope parking and improving slope parking stability can be achieved.

Description

technical field [0001] The present application relates to the technical field of vehicle control, in particular to a parking 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 a 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 method to avoi...

AI Technical Summary

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 parking control method has the problem of unstable parking on slopes
