摘要： A method of estimating brake pad wear includes determining required braking energy to be dissipated by a braking system as a fraction of total kinetic energy according to an energy partitioning model. The required braking energy is distributed to vehicle braking mechanisms according to a vehicle dynamics model. Rotor temperature of each brake rotor may be determined according to a rotor temperature model that utilizes the required braking energy and the distribution of the required braking energy, and determining brake pad wear of each brake pad according to a brake pad wear model that utilizes the rotor temperature and the distributed required braking energy. A first brake pad wear model is implemented under first operating conditions, and a second brake pad wear model under second operating conditions. The brake pad wear is indicated via a brake pad wear indicator output device. A vehicle has a controller that implements the method.

摘要： A brake temperature monitoring system configured to monitor at least one of a rotor and hydraulic fluid of a brake mechanism for a vehicle. The system including a controller including a processor and an electronic storage medium, a vehicle velocity sensor, an ambient temperature sensor, and a pre-programmed module. The vehicle velocity sensor is configured to output a velocity signal to the processor. The ambient temperature sensor is configured to output an ambient temperature signal to the processor. The model is pre-programmed into the electronic storage medium, and is adapted to estimate the temperature of at least one of the rotor and the hydraulic fluid. The estimation is based on an ambient air temperature, and a pre-established relationship between a conductive heat transfer factor and a convective heat transfer factor. The convective heat transfer factor is a function of vehicle velocity.
