Description
TECHNICAL FIELD
[0001] The present application relates to the field of automobile technology, in particular to a wake-up starting system. BACKGROUND
[0002] Tire is an important component of automobile, and the main factor for tire performance is tire pressure. When the tire pressure is too low or too high, it will affect the use performance of the tire and reduce the service life of the tire. Therefore, it is necessary to monitor the tire pressure of the vehicle. Direct TPMS can provide real-time tire pressure and temperature data for the driver, so that the driver can adjust the driving mode in time, prevent tire burst risk and maintain the tire. The TPMS is composed of a receiver and a sensor. The sensor is mostly installed in the meridian tire (vacuum tire), which is difficult to disassemble and assemble. In order to reduce the number of battery replacement and delay the working time of the battery, it is necessary to reduce the power consumption as much as possible, and the sensor does not work during non-driving time. The traditional sensor detects the rotation of the wheel through an acceleration sensor to wake up the TPMS sensor, which has high cost. Or, the TPMS sensor is woken up by receiving the 125KHz signal transmitted by the TPMS host through the LF receiver, which is easy to interfere with the vehicle-mounted wireless device and cause false triggering, which has safety hazards.
