Uphill control method, device, vehicle controller and vehicle

Abstract

The invention discloses an uphill control method, device, vehicle controller and vehicle, wherein the method includes: obtaining the current slope of the vehicle; when the current slope is greater than a preset slope value, controlling the EPB system of the vehicle to pull When the current slope is less than or equal to the preset slope value, the motor controller controls the vehicle to park, and detects the vehicle's parking time, and when the parking time is greater than the preset time, the EPB system of the vehicle is controlled to pull rise. The control method of the embodiment of the present invention can provide an uphill assistance function for a vehicle without ESP, improve the safety and reliability of the vehicle, ensure the consistency of the full slope function, and improve the user's driving experience.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an uphill control method, device, vehicle controller and vehicle. Background technique [0002] With more and more private cars and more and more congested roads, the number of starts and stops during driving will become more and more frequent. In particular, when the vehicle stops on a slope for a short time, if the handbrake is pulled manually every time, it will not only reduce the user experience, but also reduce the service life of the brake pads. When the pedal is switched to stepping on the accelerator pedal, the vehicle is prone to slipping backwards, which poses a safety hazard. [0003] In the related technology, the uphill assist function will control the vehicle to park to keep the stationary state, so that the driver can easily start the car and operate the pedals calmly. Park Brake (Electronic Parking Brake System), and for vehicles without ESP, it is mainly r...

AI Technical Summary

Problems solved by technology

[0004] It should be noted that for vehicles without ESP, there are mainly two ways to realize the above functions: one is that the full slope is realized by the cooperation of VCU and MCU, but as the slope of the road increases, the parking effect of the vehicle will become worse, and even Complete loss will cause damage to the MCU and affect the service life; the other is when the slope is low, it is realized by the VCU and MCU, and when the slope is high, it is realized by the EPB, but it will cause inconsistent functional status, and the MCU realizes when parking , often can only be parked for a few minutes or even a few seconds. When the EPB is parked, it can be parked for a long time. Once the user does not notice the slope change, it is prone to danger and poses a safety hazard.
