Tire pressure monitoring system based on BCM and TPMS response circuit

Abstract

The invention discloses a tire pressure monitoring system based on a BCM and TPMS response circuit. The tire pressure monitoring system comprises an emitting module and a vehicle-mounted BCM, a communication circuit is formed between the emitting module and the vehicle-mounted BCM and used for signal transmitting of pressure and temperature , the vehicle-mounted BCM emits signaling activation to the emitting module, and the emitting module directly sends tire pressure and temperature signals to the BCM; and the vehicle-mounted BCM conducts displaying and corresponding treatment after receivingthe signals. The tire pressure monitoring system is signal response between the vehicle-mounted BCM and the emitting module, the BCM is utilized to send an activation code, and the emitting module sends the data to the BCM after receiving the activation code. The tire pressure monitoring system based on the BCM and TPMS response circuit has the advantages that 1, signal transmission is more stable, real-time emission is conducted through a feedback circuit, and real-time monitoring in the operation process of a car is achieved; 2, power consumption can be sharply reduced, and the service lifeof a sensor is prolonged; and 3, the signals are received by the vehicle-mounted BCM, and complex wiring and decoration on the car are reduced.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a tire pressure monitoring system based on a BCM and TPMS response loop. Background technique [0002] Tire pressure monitoring is a real-time automatic monitoring of tire pressure during driving, and an alarm for tire leakage and low air pressure to ensure driving safety. Data show that the ratio of car accidents caused by tire blowouts in vicious traffic accidents is as high as 70%, and among all the factors that can cause tire blowouts, insufficient tire pressure is the primary cause. This is not sensational. Even if you do not choose a model with tire pressure monitoring, you should pay more attention to the tires of your vehicle to avoid serious damage to people and cars. [0003] Existing tire pressure monitoring exists in the high-frequency unilateral transmission of the transmitting module, and it is impossible to know whether the signal has been received, and there are situations ...
