System to estimate the change in temperature of a brake component

摘要

A system configured to estimate the change in temperature of a brake component of a vehicle brake during a braking operation, the system comprising; a weight estimation module for estimating the weight of a vehicle to which the brake is fitted; a volume estimation module for estimating the volume of the brake component; a temperature model module for calculating a change in temperature during brake application on the basis of a relationship between the weight of the vehicle as estimated by the weight estimation module, the volume or the brake component as estimated by the volume estimation module, the deceleration of the vehicle and further constants of the vehicle and/or brake. Preferably this temperature model is used to determine how much force is used to apply a parking brake.
