The invention discloses a vehicle roll control method, which comprises the following steps: setting an allowable maximum steering angle theta m when the vehicle does not roll, and not executing roll when the steering angles of lane change, obstacle avoidance and the like are slightly adjusted by detecting the steering angle of the vehicle, so as to ensure the driving smoothness and riding comfortof the vehicle; setting an allowable maximum lateral force Pm, and measuring the instantaneous lateral force of the vehicle to counteract the rollover force of the vehicle caused by topographic changeor side slope driving so as to guarantee the driving stability and safety of the vehicle; by retaining part of the lateral force, the cross-slope driving experience of the driver and passengers is retained.
本申请公开了车辆侧倾控制方法,包括:设置一个不侧倾时许用最大转向角θ,通过检测车辆转向角,进行变道、避障等转向角小量调整时不执行侧倾,以便保障车辆的驾驭平顺性和乘坐舒适性;设置一个许用最大侧向力P,通过测量车辆瞬时侧向力,抵消由于地形变化、或侧坡行驶引起车辆侧翻力,以保障车辆行驶稳定性与安全性;通过保留部分的侧向力,以便保留驾乘者的横坡行驶体验感。
