The invention relates to a method for determining whether an automatic collision avoidance steering should be performed. The method includes obtaining a predicted vehicle trajectory, the predicted vehicle trajectory including a predicted lateral acceleration and a predicted lateral acceleration rate of change of the vehicle along the predicted vehicle trajectory; obtaining a first threshold value of reachable transverse acceleration and a second threshold value of reachable transverse acceleration change rate of the vehicle; determining whether the predicted vehicle trajectory is reachable by comparing the predicted lateral acceleration to a first threshold and comparing the predicted lateral acceleration rate of change to a second threshold; in response to reachable, communicating to a control system of the vehicle that an automatic collision avoidance steering should be performed; in response to the unreachable: determining a lateral offset of the vehicle; responsive to the lateral offset being less than or equal to a third threshold, communicating that an automatic collision avoidance steering should be performed; in response to the lateral offset being greater than a third threshold, an automatic collision avoidance steering should not be performed is communicated.
本发明涉及用于确定自动碰撞避免转向操纵是否应被执行的方法。方法包括:获得预测的车辆轨迹,预测的车辆轨迹包括车辆的沿着预测的车辆轨迹的预测的横向加速度和预测的横向加速度变化率;获得车辆的可达到的横向加速度的第一阈值和可达到的横向加速度变化率的第二阈值;通过将预测的横向加速度与第一阈值进行比较以及将预测的横向加速度变化率与第二阈值进行比较来确定预测的车辆轨迹是否可达到;响应于可达到,向车辆的控制系统传达自动碰撞避免转向操纵应被执行;响应于不可达到:确定车辆的横向偏移;响应于横向偏移小于或等于第三阈值,传达自动碰撞避免转向操纵应被执行;响应于横向偏移大于第三阈值,传达自动碰撞避免转向操纵不应被执行。
