Abstract:

A method and system for controlling high idle creep through brake-by-wire braking is disclosed for a vehicle () having an engine () operable at a first idle speed and at a second faster idle speed. The method () includes the steps of determining whether the engine is operating at the second idle speed (), and friction braking () a wheel () through a brake-by-wire system () to offset additional torque provided to the wheel () by the engine () operating at the second idle speed. The system includes a braking device () for braking a wheel () in response to a braking signal () and a controller () for generating a braking signal to offset additional power provided to the wheel () by the engine () operating at the second idle speed.
