摘　　要：针对高速行驶的车辆处于大转角、避障等紧急工况下容易出现侧翻的问题,本文中提出了采用差动制动与主动横向稳定杆联合对车辆进行侧翻控制策略。为提高对车辆侧翻的控制效果,一方面通过全轮差动制动来提高车辆的横摆稳定性,防止车辆由于失稳产生绊倒性侧翻,并减小车辆的侧倾;另一方面,考虑到处于紧急工况下车辆的非线性与时变性,采用主动横向稳定杆并设计了2阶滑模超螺旋控制器来动态跟踪车辆的理想侧倾角,实现驾驶员对车辆侧倾姿态的准确判断,防止驾驶员产生误操作,进一步提高了车辆的防侧翻能力。最后,通过硬件在环试验对提出的主动横向稳定杆与差动制动联合控制策略的有效性进行了验证。In view of the problem that the high-speed driving vehicle is prone to rollover in sharp turning or obstacle avoidance maneuver,a rollover control strategy with the combination of differential braking and active anti-roll bar is put forward.For enhancing rollover control effect,on one hand,all-wheel differential braking is adopted to enhance the yaw stability of vehicle,prevent the vehicle from tripping rollover due to instability,and reduce the probability of vehicle rollover;on the other hand,taking into account the nonlinearity and time variability of vehicle under emergency conditions,an active anti-roll bar is applied and a second-order sliding mode super-twisting controller is designed to dynamically track the ideal roll angle of the vehicle for achieving accurate judgment of the inclination of vehicle rollover,preventing the mal-operation of driver and further enhancing the anti-rollover capability of vehicle.Finally,a hardware-in-loop test is conducted to validate the effectiveness of the combined control strategy with active anti-roll bar and differential braking.
