The invention provides a safety protection method, device and equipment after automobile collision and a readable storage medium, and the method comprises the steps: receiving a collision signal sent by a sensor of a target motor after the target motor is collided; according to the collision signal, the target motor is actively controlled until the target motor is in an active stable control state, whether the counter electromotive force of the target motor is smaller than or equal to a preset threshold value or not is determined, and active control comprises the steps that three-phase short circuit of the target motor is controlled, a battery relay is controlled to be switched off, and active discharging is conducted after inverter short circuit is controlled; and when determining that the back electromotive force of the target motor is less than or equal to the preset threshold, controlling the target motor to enter a follow current protection mode. By means of the method, the effect of reasonable safety protection after automobile collision can be achieved.
本申请提供一种汽车碰撞后安全防护的方法、装置、设备和可读存储介质,该方法包括,在目标电机发生碰撞后,接收目标电机的传感器发送的碰撞信号;根据碰撞信号,对目标电机进行主动控制,直到目标电机处于主动稳定控制状态下,确定目标电机的反电动势是否小于等于预设阈值,其中,主动控制包括:控制目标电机三相短路、控制电池继电器断开和控制逆变器短路后主动放电;在确定目标电机的反电动势小于等于预设阈值时,控制目标电机进入续流防护模式。通过该方法可以达到在汽车碰撞后实现合理的安全防护的效果。
