Tire pressure management system with enhanced wireless security and control method thereof

摘要

A tire pressure management system with enhanced wireless security and a control method thereof are provided. The tire pressure management system includes initiators configured to wirelessly transmit a tire information request signal to tire pressure sensors when the initiators receive a first signal, a receiver configured to receive packets including the tire information from the tire pressure sensors, and an electronic control unit (ECU) configured to transmit the first signal to the initiators. Further the ECU is configured to measure a delay after transmission of the first signal until the packets are received. The ECU is also configured to transmit the tire information within the received packets to a cluster or drop the received packets in response to the delay.

1. A tire pressure management system, comprising:
a memory configured to store program instructions; a controller configured to execute the program instructions, the program instructions when executed configured to:
transmit a tire information request signal to tire pressure sensors in response to a first signal;wirelessly transmit the first signal to a plurality of initiators under a specific driving condition; receive packets including the tire information from tire pressure sensors; measure a delay after transmission of the first signal until the packets are received; and transmit the tire information within the received packets to a cluster or drop the received packets based on the delay.
