The invention relates to the technical field of automobile early warning, in particular to an automobile rear-end collision monitoring and damage preventing method and system, an automobile and a storage medium. The method is applied to an automobile rear-end collision monitoring and damage preventing system, the system comprises an automobile machine processor, and the method comprises the steps that the acceleration and the accelerator state of an automobile are monitored in real time, when the acceleration and the accelerator state do not correspond to each other and fall into a rear-end collision state threshold value, it is confirmed that the automobile enters a rear-end collision state, and an emergency damage preventing mechanism is started; in the emergency anti-damage mechanism, whether an automobile gearbox is in a parking gear or not is monitored, and a parking gear gearbox locking mechanism is released; and the brake is controlled to perform full-force braking until the rear-end collision state is stopped. The existing acceleration sensor in the automobile is utilized, whether the rear-end collision condition occurs or not is accurately judged according to the automobile acceleration and the accelerator state, the whole automobile is braked emergently before a driver after the rear-end collision occurs, the fixed hook of the P gear is unlocked as soon as possible, permanent damage to the gearbox is prevented, the implementation cost is low, and the reliability is high.

    本发明涉及汽车预警的技术领域,尤其涉及一种汽车追尾监控防损坏方法、系统、汽车及存储介质。方法应用于汽车追尾监控防损坏系统,系统包括有车机处理器,方法包括:实时监控汽车的加速度和油门状态,当加速度和油门状态不对应并落入追尾状态阈值时,确认进入被追尾状态,启动应急防损坏机制;应急防损坏机制内,监控汽车变速箱是否位于停车挡并解除停车挡变速箱锁止机构;控制制动器全力制动,直至被追尾状态停止。本发明利用汽车中现有的加速度传感器,通过汽车加速度和油门状态来精准判断是否有追尾状况发生,并在追尾发生后先于驾驶员进行全车紧急制动,并尽快解开P档的固定挂钩,防止发生变速箱的永久性损坏,其实施成本低,可靠性高。
