1. A method for controlling a powertrain of a vehicle with wheels, the vehicle having a pedal actuated by a driver, the method comprising:

  • generating powertrain torque transmitted to the wheels in a first relation to actuation of the pedal by the driver during a first condition where said transmitted torque causes said wheels to slip relative to a surface;

    overriding said driver actuated powertrain torque to control said slip; and

    during a second condition after said first condition where said vehicle is moving less than a threshold, generating powertrain torque transmitted to the wheels in a second relation to actuation of the pedal by the driver, where for a given pedal position, less powertrain torque is transmitted with said second relation compared to said first relation.
