The invention relates to a functional safety verification method for a crash sensor of an airbag system of a vehicle. The method comprises the steps of receiving a first signal from the crash sensor and a second signal from another sensor; and judging whether the value of the first signal is within the range of a preset first threshold value and whether the value of the second signal is within the range of a preset second threshold value, and if the judgment result is yes, considering that the first signal from the crash sensor is valid and considering that the vehicle is collided. According to the method, the functional safety verification of the crash sensor of the airbag system of the vehicle can be completed under the condition that extra cost is not increased. The invention further relates to an airbag controller capable of carrying out the method.

    本发明涉及一种用于车辆的气囊系统的碰撞传感器的功能安全校验方法,该方法包括以下步骤:接收来自所述碰撞传感器的第一信号以及来自它方传感器的第二信号;以及,判断所述第一信号的值是否处于预设的第一阈值的范围内以及所述第二信号的值是否处于预设的第二阈值的范围内,如果判断结果为是,则认为来自所述碰撞传感器的第一信号是有效的并且认为车辆发生了碰撞。本发明的方法可以在不增加额外成本的情况下完成车辆的气囊系统的碰撞传感器的功能安全校验。本发明还涉及能执行所述方法的气囊控制器。
