The invention discloses a vehicle door safety unlocking method after vehicle collision and a vehicle-mounted intelligent terminal. The vehicle door safety unlocking method after the vehicle collision comprises the steps that after the vehicle is collided, if a vehicle-mounted intelligent terminal receives a vehicle door locking signal, whether a low-voltage power supply battery of the vehicle supplies power normally or not is judged; if the low-voltage power supply battery of the vehicle cannot supply power normally, a standby battery of the vehicle-mounted intelligent terminal is controlled to be started, and whether the vehicle is in a safe state or not is judged according to the speed of the vehicle; and if the vehicle is in the safe state, power is supplied to a door lock motor of at least one vehicle door through a standby battery of the vehicle-mounted intelligent terminal so as to unlock the at least one vehicle door. According to the vehicle door safety unlocking method after the vehicle collision, after the vehicle collision occurs, passengers can still open the vehicle door under the condition that the vehicle is in a safe state, so that the safety of the passengers is better protected.

    本发明公开了一种车辆碰撞后的车门安全解锁方法以及车载智能终端。其中,车辆碰撞后的车门安全解锁方法包括:当车辆发生碰撞后,如果车载智能终端接收到车门闭锁信号,则判断车辆的低压供电电池是否正常供电;如果车辆的低压供电电池无法正常供电,则控制车载智能终端的备用电池启动,并根据车辆的车速判断车辆是否处于安全状态;如果车辆处于安全状态,则通过车载智能终端的备用电池给至少一个车门的门锁电机供电,以使至少一个车门解锁。该车辆碰撞后的车门安全解锁方法,可实现在车辆发生碰撞后,乘客依然可以在车辆处于安全状态的情况下打开车门,从而更好地保护乘客安全。
