The invention provides an I-type TPMS alarm method based on the I-type TPMS alarm system based on the PEPS antenna and the TPMS sensor, and the method specifically comprises the following steps: S1, when a vehicle is detected to be in an ON gear, the TPMS control module periodically controls the PEPS antenna to send a trigger signal, and the trigger signal is a high-power carrier signal; s2, each TPMS sensor transmits a high-frequency tire pressure radio-frequency signal to the TPMS control module in a time-sharing manner based on the trigger signal; and S3, the TPMS control module analyzes the received tire pressure radio frequency signal, judges whether the corresponding tire has underpressure or not, and sends out related alarm information. According to the TPMS alarm strategy provided by the invention, on the premise that the hardware cost of the vehicle is not increased, the alarm function of the I-type sensor can be realized only by changing software, and the cost is saved.

    本发明提供了一种基于所述基于PEPS天线和TPMS传感器的I类TPMS报警系统的I类TPMS报警方法,所述方法具体包括如下步骤:S1、在检测到车辆处于ON档时,TPMS控制模块周期性控制PEPS天线发出触发信号,触发信号为大功率载波信号;S2、各TPMS传感器基于触发信号分时发射高频的胎压射频信号至TPMS控制模块;S3、TPMS控制模块对接收到的胎压射频信号进行解析,判断对应轮胎是否存在欠压,并发出相关报警信息。本发明提供的TPMS报警策略在不增加车辆硬件成本的前提下,仅仅通过更改软件即可实现I类传感器的报警功能,节省成本支出。
