Value 2, ε4 is the setting acceleration parameter;第二步：数据采集，所述压力传感器和加速度传感器实时对轮胎进行数据采集；The second step: data collection, the pressure sensor and acceleration sensor perform real-time data collection on the tire;第三步：数据分析，所述控制器分析轮胎压强以及其变化率、分析轮胎的切向加速度和法向加速度；The third step: data analysis, the controller analyzes the tire pressure and its rate of change, and analyzes the tire's tangential acceleration and normal acceleration;第四步：通过数据分析得到的轮胎气压P、压强变化率|D p\dt|、绝对加速度a等数值与参数设定值进行比较，从而得出是否触发控制器打开气体发生器。 The fourth step: The tire pressure P, pressure change rate |D p \dt|, absolute acceleration a and other values obtained through data analysis are compared with the parameter setting values to determine whether to trigger the controller to turn on the gas generator.其中第三步中数据分析具体为：当汽车的速度低于40km/h，继续进行数据采集；当汽车的速度高于40km/h，分析此时轮胎气压P以及压强变化率|D p\dt|，与设定值进行比较；若此时轮胎气压P小于设定值ε1且压强变化率|D p\dt|大于设定值ε2，将触发控制器打开气体发生器；反之，继续分析轮胎气压P、压强变化率|D p\dt|和绝对加速度a；若此时轮胎气压P小于等于设定值ε3且绝对加速度a大于等于设定值ε4，将触发控制器打开气体发生器。 The data analysis in the third step is specifically: when the speed of the car is lower than 40km/h, continue to collect data; when the speed of the car is higher than 40km/h, analyze the tire pressure P and the pressure change rate at this time |D p \dt |, compare with the set value; if the tire pressure P is less than the set value ε1 and the pressure change rate |D p \dt| is greater than the set value ε2, the controller will be triggered to turn on the gas generator; otherwise, continue to analyze the tire Air pressure P, pressure change rate |D p \dt| and absolute acceleration a; if the tire pressure P is less than or equal to the set value ε3 and the absolute acceleration a is greater than or equal to the set value ε4, the controller will be triggered to turn on the gas generator.
