Door-triggered tire pressure detection system and method for waking up the same

Abstract

A car door-triggered tire pressure detection system includes an on-board unit with an ECU unit connected to a main high-frequency transceiver module, a main display, and a door sensing module. The on-board unit does not include a vehicle low- frequency circuit and a vehicle low-frequency antenna. Multiple TPMS each include a TPMS main control unit connected to a TPMS high-frequency transceiver module. Each TPMS does not include a TPMS low-frequency circuit and a TPMS low-frequency antenna. When the door sensing module detects a car door is opened, the main display shows the tire pressure values returned by each TPMS. The problem of excessive antennas used in known wireless transmission systems is improved. When the door sensing module detects the opening of the car door, the main display shows the tire pressure values returned by each TPMS.
