Abstract
A vehicle brake system and a method of control. The vehicle brake system may include a friction brake and a secondary brake that may be applied to slow rotation of a vehicle wheel when a wheel slip condition is detected.
Claims20
A method of controlling a vehicle brake system comprising:
- applying a friction brake to slow rotation of a vehicle wheel;
- and
- pulsing a secondary brake that provides a secondary brake torque that slows rotation of the vehicle wheel by decreasing torque that is provided to the vehicle wheel to rotate the vehicle wheel when a wheel slip condition is detected.
A method of controlling a vehicle brake system comprising:
- applying a friction brake torque with a friction brake to slow rotation of a vehicle wheel;
- determining whether a wheel slip condition is present;
- and
- applying a secondary brake torque with a secondary brake in proportion to a wheel slip error when a wheel slip condition is present, wherein the secondary brake torque slows rotation of the vehicle wheel by decreasing torque that is provided to the vehicle wheel to rotate the vehicle wheel.

A vehicle brake system comprising:
- a friction brake that is disposed proximate a vehicle wheel and that is configured to provide a friction brake torque to slow rotation the vehicle wheel;
- a secondary brake that is configured to provide a secondary brake torque that slows rotation of the vehicle wheel by decreasing torque that is provided to the vehicle wheel to rotate the vehicle wheel;
- and
- a controller that controls the friction brake and the secondary brake such that the friction brake torque and the secondary brake torque are applied when a wheel slip condition is detected.
