【摘要】 针对汽车在转弯制动时出现的制动距离过长和侧向路径偏离状况,提出了利用两侧轮胎制动力差产生的横摆力矩控制汽车侧向路径偏离的控制策略,设计了模糊控制器.仿真研究表明,利用所提出的横摆力矩模糊控制策略能减少汽车在弯道路段制动时的侧向路径偏离距离,使汽车在制动时能保持预期轨迹,提高了汽车的制动安全性和稳定性.更多还原

【Abstract】 According to the variation of side slip angle and vertical load of wheel combined with the characteristic curved surface,the control strategy of finding wheel optional slip ratio under braking condition was proposed.To the situation of long braking distance and braking wandering on a crooked road,the yaw moment control strategy about lane restoring was proposed and the fuzzy controller was designed,and the simulation research on the wandering condition after braking on crooked road was carried out.The results showed the yaw moment fuzzy control strategy could reduce the braking distance on crooked road,keep automobile driving on the correct lane and improve braking safety and stability of automobile.更多还原
