Abstract
A vehicle braking system () has a primary braking unit () with a first pressure generating unit () and a first reservoir (). The vehicle braking system () further has a secondary braking unit () with a second pressure generating unit () and second reservoir (). A method of operating the vehicle braking system () includes actuating the pressure generating unit () of the primary braking unit () thereby pressurizing a fluid at a wheel cylinder () to slow or stop the vehicle. The wheel cylinder () is depressurized in response to an electrical signal provided to an electronic control unit (). The fluid is transferred from the wheel cylinder () to the second reservoir (). The fluid path (PI) between the wheel cylinder () and the second reservoir () is shorter and has less fluid resistance than the fluid path (P) between the wheel cylinder () and the first reservoir (). The present invention further comprises two braking systems. The present inventions are intended for fast pressure depressurization at quick start or launch control.
