The invention discloses an automatic emergency collision avoidance method based on forward and backward environment perception, which comprises the following steps: acquiring target object motion information and own vehicle motion information based on vehicle-mounted forward and backward environment perception sensors, the target object motion information comprising forward vehicle motion information and backward vehicle motion information; and obtaining a braking type according to the target object motion information and the vehicle motion information, calculating forward active collision avoidance braking parameters, and executing braking according to the forward active collision avoidance braking parameters. The invention further discloses an automatic emergency collision avoidance system based on forward and backward environmental perception. In the collision avoidance judgment process of a forward vehicle or other traffic participants, the influence of backward traffic environment factors is considered, and under the condition that the safety of a driver is guaranteed, full-force braking can be achieved to guarantee the safety of a front traffic participant.
本发明公开了一种基于前后向环境感知的自动紧急避撞方法,包括:基于车载前向及后向环境感知传感器获取目标对象运动信息和自车运动信息,所述目标对象运动信息包括前向车辆运行信息和后向车辆运动信息;根据目标对象运动信息和自车运动信息获得制动类型,并计算前向主动避撞制动参数,以前向主动避撞制动参数执行制动。本发明还公开了一种基于前后向环境感知的自动紧急避撞系统。本发明在对前向车辆或者其他交通参与者进行避撞判断过程中,考虑了后向的交通环境因素的影响,能在保证驾驶员安全的情况下,可以全力刹车保证前方交通参与对象的安全。
