Vehicle Brake Disc Temperature Monitoring Method and Apparatus

A vehicle brake disc temperature monitoring unit includes (i) a temperature collection module, which collects temperature values near the brake disc that change over time during vehicle braking, (ii) a temperature estimation module, which uses an observation model and a state estimation model to estimate the temperature of the brake disc based on the temperature values collected by the temperature collection module and the estimated values of the actual temperature of the brake disc through the Kalman filtering process, and (iii) a control module, which adjusts and controls the braking state of the vehicle braking system through the estimated temperature values and the detection values of the temperature sensor. In view of the above, it is possible to use a temperature sensor that is not in contact with the brake disc and utilize the Kalman filtering method to effectively estimate the temperature of the brake disc when it is impossible to directly measure the temperature of the brake disc using the temperature sensor installed on or abutting the brake disc, improving monitoring accuracy and allowing the safe and reliable monitoring of the vehicle's braking system and thereby improving the safety of the vehicle during driving.
