Abstract
A method of controlling the driving wheels of a vehicle having an internal combustion engine wherein it is determined if a vehicle stuck or not and then, if stuck, the maximum permissible amount of wheel slip is increased with the intent of removing loose material, such as snow, underneath the tires. If the vehicle remains stuck and wheel slip continues, the amount of driving power and torque to the wheels is then reduced. Conversely, if the spin is not present at the subsequent gas pedal application (tip-in), and the vehicle is still stuck, the wheel torque limit is increased.
