The invention relates to an automobile direct type tire pressure monitoring and alarming system and method based on a sensor and an automobile, and the method is characterized in that a controller outputs a tire pressure state as an initial state before the automobile is started and a tire pressure sensor is awakened when the automobile speed is greater than 30km/h and a tire pressure value signal is received within 1min when the automobile speed is greater than 30km/h for the first time; if the tire pressure value signal is still not received after the vehicle speed is greater than 30km/h for the first time or the tire pressure signal is not received after a certain tire sensor signal is received, the tire pressure state output by the controller is a sensor loss state; after the tire pressure sensor battery power low flag bit is continuously received, the state is a sensor battery power low state; if the received continuous tire pressure value is smaller than or equal to 80% Pwarm, the tire is in an under-pressure state; if the continuous quick air leakage frame is received and the tire pressure value is continuously decreased, the tire is in a quick air leakage state; the tire pressure initialization stage is added, and the driving safety and comfort of a user are improved.
本发明涉及一种基于传感器的汽车直接式胎压监测报警系统、方法及车辆,从车辆启动到车速大于30km/h唤醒胎压传感器前及车速首次大于30km/h的1min内收到胎压值信号前,控制器输出胎压状态为初始化状态;车速首次大于30km/h后仍未收到胎压值信号或在收到某个轮胎传感器信号后未收到胎压信号,控制器输出胎压状态为传感器丢失状态;连续收到胎压传感器电池电量低标志位后,为传感器电池电量低状态;若收到连续胎压值≤80%Pwarm,为欠压状态;若收到连续快速漏气帧且胎压值为持续递减,为快速漏气状态;本发明增加了胎压初始化阶段,提高了用户行车安全性和舒适性。
