The invention discloses a control method of an acceleration sensor system. The control method comprises the following steps: acquiring at least two acceleration sensors arranged in a preset collision direction of a vehicle; judging whether the deviation of the acquired data of any two acceleration sensors is greater than an abnormal threshold value or not; if not, the data collected by the at least two acceleration sensors are normal; if yes, obtaining a current vehicle acceleration based on a vehicle motion model; based on the current vehicle acceleration and the vehicle driving direction, the acceleration is obtained; the acceleration is compared with the data, and the faulted sensor is identified. According to the method, an acute angle type sensor placement mode is used, the abnormal sensor state can be accurately positioned through the data of the double sensors in combination with the real vehicle motion data, corresponding fault measures are executed, the robustness of the system can be improved, the system failure risk is reduced, and the system detection capacity is improved.

    本发明公开了一种加速度传感器系统的控制方法,包括:获取车辆在预设碰撞方向上设置的至少两个加速度传感器;判断任意两个所述加速度传感器采集数据偏差是否大于异常阈值;不大于,至少两个加速度传感器采集的数据正常;若大于,基于车辆的运动模型得到当前车辆加速度;基于当前车辆加速度和车辆行驶方向,得到加速度;将加速度与数据进行对比,识别出故障的传感器。本发明使用锐角式传感器摆放方式,通过双传感器本身数据再结合实车运动数据,可以准确定位异常传感器状态,并执行相应的故障措施,可以增加系统的鲁棒性,降低系统失效风险,提升系统检测能力。
