The invention discloses a motion control safety monitoring and correcting strategy for a vehicle. The strategy at least comprises the following steps of calculating the pre-tracing curvature of a front road; obtaining the transverse acceleration corresponding to the pre-tracing curvature at different longitudinal speeds, and comparing the transverse acceleration with the safe acceleration in real time to obtain the maximum transverse acceleration; and calculating the maximum steering wheel turning angle corresponding to different longitudinal speeds and the maximum transverse acceleration in real time. According to the motion control safety monitoring and correcting strategy, the turning angle threshold value of the steering wheel can be calculated and determined in real time according to the road condition and the vehicle condition, it is guaranteed that the steering wheel does not exceed the turning angle threshold value in the rotating process, and the vehicle is in a comfortable and safe state all the time.

    本申请公开了一种用于车辆的运动控制安全监测和校正策略,包括至少如下步骤:计算前方道路的预描曲率;获取不同纵向速度下预描曲率所对应的横向加速度并与安全加速度进行实时比较以得到最大横向加速度;实时计算不同纵向速度、最大横向加速度所对应的最大方向盘转角。根据本申请的运动控制安全监测和校正策略,可以根据道路情况和车辆情况实时计算并确定方向盘的转角阈值,保证方向盘在转动过程中不会超出转角阈值,车辆始终处于舒适且安全的状态。
