Abstract

本发明公开一种对接路面冗余制动的防抱死控制方法、系统、车辆及介质。方法包括:首先根据两个前轮的滑移率、不稳定时间、轮减速度、车速等信息识别是否处于对接路面。当识别为高附着路面至低附着路面的对接路面时,车辆防抱死系统进入减压状态,持续减压直至车辆离开高附着路面至低附着路面的对接路面,保证车轮从高附着路面驶入低附着路面时,能够快速减压,防止车轮抱死。当识别为低附着路面至高附着路面的对接路面时,车辆防抱死系统进入增压状态,并按照较大的加强梯度快速增压,直至车辆任一前轮满足不稳定条件,从而保证车轮从低附着路面驶入高附着路面时,能够快速恢复至较高的制动压力,提高制动减速度。

The invention discloses an anti-lock control method, an anti-lock control system, a vehicle and a medium for redundant braking of a butt joint road surface. The method comprises the steps of firstly identifying whether the two front wheels are on a butt joint road surface or not according to the information such as the slip rate, the unstable time, the wheel deceleration, the vehicle speed and the like of the two front wheels. When the road surface is identified as the butt joint road surface from the high adhesion road surface to the low adhesion road surface, the anti-lock braking system of the vehicle enters a decompression state, and the vehicle is continuously decompressed until the vehicle leaves the butt joint road surface from the high adhesion road surface to the low adhesion road surface, so that the vehicle wheels can be rapidly decompressed and prevented from locking when the vehicle wheels drive into the low adhesion road surface from the high adhesion road surface. When the road surface is identified as a butt joint road surface from a low adhesion road surface to a high adhesion road surface, the anti-lock braking system of the vehicle enters a pressurizing state and rapidly pressurizes according to a larger reinforcing gradient until any front wheel of the vehicle meets an unstable condition, so that the wheels can be ensured to rapidly recover to higher braking pressure and improve braking deceleration when the wheels drive into the high adhesion road surface from the low adhesion road surface.
