Claim:
1. A vehicle control system for at least one vehicle subsystem of a vehicle, the system comprising one or more electronic controllers programmed to be operable to: detect an occurrence of a wheel slip event at one or more wheels of the vehicle and reduce an amount of wheel slip via a vehicle slip control process when the vehicle is travelling at a speed that is above a threshold speed, the threshold speed being a speed below which the vehicle slip control process is not permitted to intervene to reduce wheel slip; and prevent excessive wheel slip via a vehicle launch assist (VLA) process when the vehicle is travelling below the threshold speed below which the vehicle slip control process is not permitted to take action to reduce slip, wherein when the launch assist process is active, the one or more electronic controllers impose a set of one or more prescribed constraints on an amount of torque applied to the one or more wheels of the vehicle, wherein the set of one or more constraints are determined by reference to information or data in respect of the amount of wheel torque that is applied before the amount of wheel slip exceeds a prescribed value, and further wherein the vehicle slip control process and the vehicle launch assist process are separate and distinct processes.
