Abstract: 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.

Abstract: A vehicle includes a brake system. The brake system includes a hydraulic brake line having a line pressure. The vehicle additionally includes a vacuum reservoir. The vacuum reservoir is selectively fluidly coupled to the hydraulic brake line. The vacuum reservoir is configured to, when fluidly coupled to the hydraulic brake line, reduce the line pressure during a drive cycle.

Abstract: An exemplary method for determining a remaining life expectancy of a brake component includes the steps of providing vehicle parameters that identify operating conditions of a vehicle, using the vehicle parameters to determine work done by a brake of the vehicle as brake work, using the brake work to determine brake rotor temperature, using the brake rotor temperature to determine a fatigue damage of the brake component, accumulating the fatigue damage to determine a cumulative fatigue damage of the brake component, and comparing the cumulative fatigue damage to a damage limit to provide an estimation of the remaining life expectancy of the brake component.

Abstract: An electromechanical brake system includes a caliper, an electric motor mounted to the caliper, a gear element mechanically connected to the electric motor, an actuator supported by the caliper, the actuator including an actuation member, and a controller operatively connected to the actuator. The controller is operable to selectively engage the actuation member with the gear element to positionally lock the first caliper member relative to the second caliper member.

Abstract: A system for determining thickness of a brake pad includes a controller configured to provide a total braking energy of a vehicle with a regenerative energy braking system, and a rotor braking system that includes a plurality of brake pads. The system controller determines the work done by the brake pads as a combination of front brake pad work and rear brake pad work, then accumulates the brake pad wear to provide an estimation of the brake pad thickness using the front brake pad work and the rear brake pad work. The controller outputs a message indicative of the estimation of the brake pad thickness via an output system in communication with the controller
