The invention discloses a forward and backward emergency collision control method, which comprises the following steps of: S1, judging whether a dangerous collision target exists or not, and continuing detection if no collision danger exists; if the collision risk exists, a backward sensing module is started; s2, whether a rear-end collision risk exists or not is judged, and if the rear-end collision risk does not exist, braking and pressure maintaining operation is conducted according to the forward collision risk level; s3, when it is judged that the emergency braking system is in the braking process, the pressure maintaining state is restrained, and the deceleration value is adjusted in a self-adaptive mode; and S4, when the braking pressure maintaining judgment module judges that the automobile is braked and stopped and is in the pressure maintaining state, a pressure maintaining releasing instruction is requested to the ESC execution control module, torque is requested to the EMS execution control module, and the rear-end collision risk is reduced. The invention further discloses a forward and backward emergency collision control system. Rear rear-end collision possibly caused after emergency braking can be reduced, secondary damage is avoided, and the method can be widely applied to an L2-level automobile intelligent driving assistance system.

    本发明公开了一种前后向紧急碰撞控制方法,步骤如下:S1、判断是否有危险碰撞的目标,如果没有碰撞危险,继续探测;如果有碰撞风险,启动后向感知模块;S2、判断是否存在追尾风险,如果没有追尾风险,按照前向碰撞风险等级进行制动和保压操作;S3、判断紧急制动系统处于制动过程中时,抑制保压状态,自适应调整减速度值的大小;S4、当制动保压判断模块判断自车已经刹停并处于保压状态时,向ESC执行控制模块请求释放保压指令,并向EMS执行控制模块请求扭矩,减小追尾风险。本发明还公开了一种前后向紧急碰撞控制系统。本发明能够减少紧急制动后可能引起的后方追尾,避免二次伤害,可以广泛应用于L2级别汽车智能驾驶辅助系统上。
