Abstract
In one example, a system for a vehicle is shown. The system includes a traction control system configured to adjust powertrain output to reduce wheel slip and a powertrain controller configured to control powertrain output based on actuation of a pedal of the vehicle by the driver, where a relationship between powertrain output and pedal actuation is adjusted in response to at least one of road grade and direction of wheel spin.

A method for controlling a powertrain of a vehicle with wheels on a road having a grade, 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, generating powertrain torque transmitted to the wheels in a second relation to actuation of the pedal by the driver, where a duration of said second condition varies as the road grade varies.

- overriding said driver actuated powertrain torque to control said slip;
- and
- during a second condition after said first condition, generating powertrain torque transmitted to the wheels in a second relation to actuation of the pedal by the driver, where a duration of said second condition varies depending on a direction of wheel rotation.
