The invention discloses a vehicle body rear portion anti-collision method and device.The vehicle body rear portion anti-collision method comprises the steps that surrounding information of a vehicle is obtained, whether rear portion collision will occur or not is judged through the surrounding information, current rear portion collision risk information of the vehicle is obtained, and whether the current rear portion collision risk information reaches a preset risk or not is judged; when the current rear collision risk information reaches the preset risk, the tail door popping operation and the anti-collision beam extending operation are sequentially executed, after the tail door pops up, the anti-collision beam extends out of the trunk, the extending anti-collision beam can resist rear collision outside the trunk, the invasion amount of the rear collision into a passenger compartment is reduced, the passenger compartment is protected, and the safety of the passenger compartment is improved. The vehicle body can be protected by arranging the anti-collision beam, and the maintenance cost of the vehicle body can be reduced.
本申请公开了车身后部防碰撞方法及装置,车身后部防碰撞方法通过获取车辆的周边信息,通过周边信息判断是否会发生后部碰撞,获取车辆的当前后部碰撞风险信息,判断当前后部碰撞风险信息是否达到预设风险,当当前后部碰撞风险信息达到预设风险时,依次执行尾门弹出操作和防撞梁伸出操作,尾门弹出后防撞梁伸出到后备箱外,伸出的防撞梁能够在后备箱外抵挡后部碰撞,减少后部碰撞侵入乘员舱的侵入量,对乘员舱进行保护,防撞梁的设置还能对车身进行保护,能够减少车身维修成本。
