Abstract

The invention relates to a system and method for integrating tire pressure monitoring and remote key-free entering, which are applied to a vehicle and a key remote controller for the vehicle. The key remote controller for the vehicle emits a signal with a predetermined carrier frequency. When the vehicle is in a locking state, an integrated controller in the vehicle detects an unlocking signal from the key remote controller for the vehicle, transmits a tire information requiring signal to a tire pressure sensing module if confirming an identity authentication code of the unlocking signal from the key remote controller for the vehicle. The tire pressure sensing module sends a tire information signal at least including tire pressure data within a predetermined time limit, and transmits the tire information signal at the predetermined carrier frequency. Therefore, the advantages of hardware sharing and accordance with safety specification are achieved.

Description

technical field [0001] The invention relates to a method for monitoring tire pressure, in particular to a method for integrating tire pressure monitoring and keyless entry. Background technique [0002] When the tire pressure (hereinafter referred to as tire pressure) is abnormal, it will not only reduce the life of the tire and increase the fuel consumption of the vehicle, but also affect the braking performance of the vehicle or increase the chance of a flat tire. Therefore, in order to ensure driving safety, a Tire Pressure Monitoring System (TPMS) is gradually being applied to effectively inform users of tire pressure. A general tire pressure monitoring system includes a tire pressure sensing unit and a radio frequency transceiver (collectively referred to as a tire pressure sensing module) installed on the tire, as well as a radio frequency transceiver and a display placed in the car. After the tire pressure sensing unit measures the tire pressure data, the tire pressu...
