The invention discloses a tire pressure European standard temperature compensation test method. the environment temperature TAmbent in a European standard tire pressure alarm threshold Pwarn is replaced by an average value Ttire-aver with temperature compensation, and the requirements of European standard regulations can be met by testing according to the state of a real vehicle. By the adoption of the technical scheme, TAmbent in the European standard tire pressure alarm threshold value Pwarn is replaced with the average value Ttire-aver with temperature compensation, and the requirements of laws and regulations can be met according to the real vehicle state test; the temperature compensation calculation method meets the requirement of the vehicle without a temperature sensor, and the calculation method and the test can meet the requirements of European standard regulations; the tire pressure alarm threshold value is associated with the external temperature, the problems that no temperature sensor exists and the stability of the temperature sensor is poor are solved, the tire pressure alarm threshold value meets the European standard regulation requirement, and the automobile safety is improved.
本发明公开了一种胎压欧标温度补偿的测试方法,所述的欧标的胎压报警阈值Pwarn中的环境温度TAmbient替换为带温度补偿的平均值Ttire‑aver,根据实车状态测试,即可满足欧标法规的要求。采用上述技术方案,将欧标的胎压报警阈值Pwarn中的TAmbient替换为带温度补偿的平均值Ttire‑aver,根据实车状态测试可以满足法规要求;温度补偿的计算方法满足无温度传感器的车辆,同时此计算方法及测试可以满足欧标法规的要求;胎压报警阈值与外界温度关联,解决无温度传感器及温度传感器稳定性差,使胎压报警阈值满足欧标法规要求,提高汽车安全性。
