摘　　要：由于气压制动系统采用气压传动控制,在使用过程中气压波动影响报警压力的识别,直接影响汽车行驶的安全性。文中建立了制动系统管路气压修正函数,优化修正系数,并对现有制动系统气压值数据进行了拟合处理。通过对气压值的修正处理,结果表明:所采用的修正方法和修正函数是有效的,符合实际使用情况,能够有效避免低压误报警。该方法提高了制动系统可靠性,为制动系统低压报警策略研究提供了一种可行方法。Because the air braking system adopts pneumatic transmission control,the air pressure fluctuation affects the recognition of alarm pressure in the process of using,then affects the safety of vehicle driving.The correction function of brake system pipeline air pressure was established,the correction coefficient was optimized,and the existing brake system data was modified.Through the correction of the pressure value,the results show that the correction method and correction function are effective,in line with the actual use situation,and can effectively avoid low pressure false alarm.This method improves the reliability of the braking system,and provides a feasible method for the study of alarm pressure of the braking system.
