Abstract
A system for controlling launch of a vehicle includes a pressure-providing device constructed and arranged to deliver a pressure medium to wheel brakes of the vehicle. A pressure chamber is fluidly connected with the pressure-providing device and is configured for containing the pressure medium. An electronic control unit has a processor circuit that is constructed and arranged, during a launch mode of the vehicle, to control the pressure-providing device to cause fluid from the wheel brakes to be directed to the pressure chamber so as to release the pressure medium from the wheel brakes, permitting launch of the vehicle.
Claims20
A method for controlling wheel brakes during a launch of a vehicle, the method comprising the steps of:
- upon initiation of a launch mode of a vehicle, causing fluid pressure to be held at wheel brakes of the vehicle, and
- after determining that a vehicle operating parameter threshold is reached, controlling, via a processor circuit, a brake pressure-providing device to release the fluid pressure held at the wheel brakes to permit launch of the vehicle.

One or more non-transitory tangible media encoded with logic for execution by a machine and when executed by the machine operable for:
- upon initiation of a launch mode of a vehicle that causes fluid pressure to be held at wheel brakes of the vehicle and after determining that a vehicle operating parameter threshold is reached, controlling, by the machine, a brake pressure-providing device to release the fluid pressure held at the wheel brakes to permit launch of the vehicle.
