The invention discloses a VCU (Vehicle Control Unit)-dominated anti-slip control method, which comprises the following steps that: a VCU (Vehicle Control Unit) decides to send a braking torque request control strategy to an EHB (Electronic Hydraulic Brake System) and carries out a PI (Proportional Integral) closed-loop control strategy; the control strategy that the whole vehicle control unit (VCU) decides to send the braking torque request to the electronic hydraulic braking system (EHB) specifically comprises the following steps that S10, when the vehicle is started, the whole vehicle control unit (VCU) can judge the high-pressure state of the whole vehicle at the moment. According to the method, the vehicle state after the vehicle enters the anti-slip control is recognized, and when the actual anti-slip effect cannot meet the anti-slip requirement of the vehicle, the vehicle control unit (VCU) interacts with the electronic hydraulic braking system (EHB) and coordinates timely intervention of the braking system, so that the robustness of the anti-backward-slip function of the vehicle under the extreme working condition is improved, and the anti-slip requirement of the vehicle is met. The driving safety is improved, and more safety guarantee is provided for users in Yunnan, Guichuan and Chongqing areas.

    本发明公开了一种VCU主导的防溜坡控制方法,包括整车控制单元(VCU)决策向电子液压制动系统(EHB)发出制动力矩请求控制策略和整车控制单元(VCU)进行PI闭环控制策略,所述整车控制单元(VCU)决策向电子液压制动系统(EHB)发出制动力矩请求控制策略具体包括以下步骤:步骤S10,车辆起步时,整车控制单元(VCU)会判断此时整车的高压状态。本发明通过识别车辆进入防溜坡控制后的车辆状态,当防溜坡实际效果无法满足车辆防溜需求时,整车控制单元(VCU)通过和电子液压制动系统(EHB)进行交互,通过协调制动系统适时介入,以提升车辆在极端工况下的防后溜功能鲁棒性,提高驾驶安全性,为云贵川渝地区的用户用车提供更多的安全保障。
