Abstract
A system and method is provided for braking a vehicle having multiple wheels. The method includes applying friction braking and powertrain braking to the vehicle. The method includes reducing the powertrain braking by a predetermined amount. The method also includes compensating the friction braking in an amount that is substantially the same as the predetermined amount. The method further includes redistributing the friction braking to the multiple wheels and modulating the friction braking being applied to the multiple wheels, thereby reducing the occurrence of a wheel lockup by the multiple wheels.

A method of braking a vehicle having multiple wheels, wherein the vehicle is configured to apply friction braking and powertrain braking to the vehicle, the method comprising:
- reducing the powertrain braking by a predetermined amount;
- compensating the friction braking in an amount that is substantially the same as the predetermined amount;
- redistributing the friction braking to the multiple wheels;
- and
- modulating the friction braking being applied to the multiple wheels.
A braking system for a vehicle having multiple wheels comprising:
- a powertrain configured to apply powertrain braking to the vehicle;
- a friction braking system for applying friction braking to the vehicle;
- a controller operable with the powertrain for reducing the powertrain braking by a predetermined amount;
- and
- a braking module integrated with the friction braking system and operable with the controller for compensating the friction braking in an amount that is substantially the same as the predetermined amount and for redistributing the friction braking to the multiple wheels, and modulating the friction braking being applied to the multiple wheels, thereby reducing the occurrence of a wheel lockup by the multiple wheels.
A method of braking a hybrid electric vehicle (HEV) having multiple wheels, wherein the vehicle has a motor/generator and is configured to apply friction braking and powertrain braking to the vehicle, the method comprising:
- reducing the powertrain braking by a predetermined amount by generating signals, through the use of a controller, that are received by the motor/generator and/or an engine;
- adding friction braking torque to the friction braking in an amount that is substantially the same as the predetermined amount;
- redistributing the friction braking to the multiple wheels;
- and
- modulating the friction braking being applied to the multiple wheels.
