摘要
在车辆上增加侧防翻控制能够有效地增强汽车的主动安全性能。运用AR模型测量车辆的行驶参数,在车身姿态参数测量基础上短期地对参数做出预测。以预测结果为依据设定汽车侧翻安全区间以控制汽车。在线控转向(steer-by-wire)控制器中建立控制策略,改变传动比让SBW系统提前反应,从而防止车辆侧翻,避免危险行驶状态。仿真结果显示侧翻控制能较好地保持汽车操纵稳定性,而又不影响汽车安全行驶。该控制能有效地抑制汽车侧翻及提高车辆的主动安全性能。
Roll control in vehicle is an important way to reduce traffic accidents and improve the performance of automotive active safety. The vehicle＇ s running parameters with AR model is measured and maken a short-term forecast based on vehicle attitude. Setting the rollover safety interval to control the vehicle on predicting outcomes. The control strategies change the transmission ratio that allows steering system to respond in advance. This makes vehicles avoid rollover and dangerous running status. The fectively and has no influence in vehicle＇s normal driving. performance availably. result shows the control maintains the steering stability ef- At the same time, it improves the vehicle＇s active safety
