Abstract
A system and method for use with a vehicle to provide a vehicle launch assist (VLA) function that reduces wheel slip at lower speeds and to provide a fraction control (TC) function that reduces wheel slip at higher speeds. Each function affects operation of one or more vehicle subsystems that control at least one powertrain parameter. The VLA and TC functions operate in response to a driver accelerator request to generate a drive signal that controls torque delivered to at least one driven vehicle wheel. The VLA function generates the drive signal at a first value that limits the torque to below a requested torque value representing the driver accelerator request. The TC function generates the drive signal at a second value that limits the torque to below the requested torque value. And the control system outputs a powertrain drive signal based on the lesser of first and second values.
