In accordance with exemplary embodiments, methods and systems are provided for controlling regenerative braking of a vehicle is provided that include: obtaining, via one or more sensors of the vehicle, sensor data pertaining to a load on the vehicle during a particular vehicle drive; determining, via a processor of the vehicle, a maximum regenerative braking torque for the vehicle for the particular vehicle drive based on the load on the vehicle; and controlling the regenerative braking of the vehicle during the particular vehicle drive, via instructions provided by the processor, based on the maximum regenerative braking torque for the vehicle for the particular vehicle drive.

Vehicle load adaptive regenerative braking

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.

Brake rotor for a braking system of a motor vehicle

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.

Force controlled anti-lock braking system strategy

A method of monitoring a brake corner of a vehicle including that real-time brake corner temperature data of the brake corner is detected, real-time brake corner pressure data of the brake corner is detected, and real-time brake corner torque data of the brake corner is detected. The method further includes that a brake drag or a brake pulsation is determined in response to the braking energy of the brake corner, whether the brake pedal of the vehicle is applied, and at least one of the real-time brake corner pressure data of the brake corner and the real-time brake corner torque data of the brake corner.

Intelligent brake system health monitoring

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.

Brake rotor prognosis

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

Brake pad life prognosis system for regenerative braking vehicles

A brake component comprising: (a) one or more tie bars, and (b) one or more open spaces on each side of the tie bar, wherein during a brake apply the one or more tie bars each allow a brake pad to rotate into the open spaces of the brake component while the tie bar remains an only point of contact of the brake component.
