AI Technical Summary
Existing tire pressure monitoring systems (TPMS) use a one-way high-frequency broadcast communication architecture, which cannot actively trigger sensors to report data, resulting in data delays and high power consumption, and cannot meet the real-time monitoring needs of intelligent connected vehicles.
A two-way real-time communication mechanism is constructed, which enables the vehicle body controller to actively trigger the downlink and the tire pressure sensor to transmit data back uplink in real time. The sensor is woken up by a low-frequency antenna and the data is uploaded using a high-frequency channel. This is combined with a multi-mode precise wake-up strategy and a data verification and forwarding mechanism.
It enables proactive triggering, on-demand collection, and real-time transmission of tire status data, reducing sensor power consumption, extending battery life, and meeting the advanced functional requirements of intelligent connected vehicles.
