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

Abstract: A method of operating an anti-lock braking system includes that real-time brake corner temperature data, real-time brake corner pressure data real-time brake corner torque data, and deceleration parameters of the vehicle are detected. The method also includes that an apparent friction at the brake corner is determined in response to at least the real-time brake corner temperature data, the real-time brake corner pressure data, the real-time brake corner torque data, and the deceleration parameters of the vehicle.

Abstract: A brake rotor for a braking system of a motor vehicle is provided. The brake rotor includes a disc section for rotating about a longitudinal axis and engaging a brake pad assembly. The brake rotor further includes a hat section for attaching to a wheel. The hat section has a stepped surface spaced from the disc section along the longitudinal axis, and the stepped surface defines a recess for spacing the wheel and a portion of the stepped surface from one another when the wheel is attached to the hat section.

Abstract: Technical solutions are described to for determining thickness of a vehicle brake rotor. An example method includes providing vehicle parameters that identify operating conditions of a vehicle, and using the vehicle parameters to determine work done by a brake of the vehicle as brake-work. Further, the method includes using the brake work to determine brake rotor temperature, and using the brake rotor temperature to determine brake rotor wear. The method further includes accumulating the brake rotor wear to provide an estimation of the thickness of the vehicle brake rotor.
