The present invention relates to a collision point calculation method between a host vehicle and one or more target vehicles, and a method for emergency brake assisted deceleration using collision point calculation. The collision point calculation method defines one or more primary collision risk areas of the vehicle; determining predictions of motion of the host vehicle and the target vehicle; and calculating the collision time from the first vehicle intersection point, the second vehicle intersection point and the target vehicle intersection point to the intersection point. Then, the method applies a main risk collision point condition to establish: if a first collision time for the first vehicle intersection point to reach the intersection point is less than a third collision time for the target intersection point to reach the intersection point and a second collision time for the second vehicle intersection point to reach the intersection point is greater than the third collision time for the target intersection point to reach the intersection point; the collision point is located in one of the areas of the vehicle. All collision points that satisfy the primary collision point condition are sent to the actuation unit.

    本发明涉及一种本车辆与一个或多个目标车辆之间的碰撞点计算方法、以及一种使用碰撞点计算进行紧急制动辅助减速的方法。该碰撞点计算方法定义本车辆的一个或多个主要碰撞风险区域;确定本车辆与目标车辆的运动的预测;计算第一本车辆交点、第二本车辆交点和目标车辆交点到交汇点的碰撞时间。然后,该方法应用主要风险碰撞点条件,从而确立:如果第一本车辆交点到达交汇点的第一碰撞时间小于目标交点到达交汇点的第三碰撞时间并且第二本车辆交点到达交汇点的第二碰撞时间大于目标交点到达交汇点的第三碰撞时间,则该碰撞点位于本车辆的区域之一内。将满足主要碰撞点条件的所有碰撞点发送到致动单元。
