The invention relates to the technical field of safety air bag control, and provides a safety air bag control method and device. The method comprises the following steps: determining an actual vehicle distance between a reference vehicle and a target vehicle through a radar system of the target vehicle; when the target vehicle speed of the target vehicle is larger than the reference vehicle speed of the reference vehicle, based on the braking acceleration of the target vehicle, the target vehicle speed and the reference vehicle speed, the theoretical vehicle distance variation between the reference vehicle and the target vehicle in the process that the target vehicle is reduced to the reference vehicle speed from the target vehicle speed is determined; and when the theoretical vehicle distance variable quantity is larger than the actual vehicle distance, an air bag controller of the target vehicle is started in advance, so that an air bag is detonated when the started air bag controller receives the detonation signal. According to the method, the air bag controller is started in advance when it is predicted that even if the target vehicle slows down, the reference vehicle is rear-ended, and the air bag can be immediately detonated once the detonation signal is received, so that the time delay of detonation of the air bag during collision is shortened, and more effective safety protection is provided for a user.
本申请涉及安全气囊控制技术领域,提供了一种安全气囊控制方法及装置。该方法包括:通过目标车辆的雷达系统,确定参考车辆与目标车辆之间的实际车距;当目标车辆的目标车速大于参考车辆的参考车速,基于目标车辆的制动加速度、目标车速和参考车速,确定目标车辆从目标车速降至参考车速的过程中参考车辆与目标车辆之间的理论车距变化量;当理论车距变化量大于实际车距,预先启动目标车辆的气囊控制器,以使启动后的气囊控制器在收到点爆信号时点爆气囊。本申请在预测出即使目标车辆降速也会追尾参考车辆时预先启动气囊控制器,一旦收到点爆信号则能够立刻点爆气囊,缩短了碰撞发生时气囊点爆的延时,为用户提供了更有效的安全保护。
