Traction control system and method for a vehicle
First Claim
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.

Abstract
In one example, A method for controlling a powertrain of a vehicle with wheels, the vehicle having a pedal actuated by a driver, is described. The method may include 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.

10. 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 and reduce said slip; and
during a second condition after said first condition where said vehicle is moving less than a threshold and the driver has released the pedal, 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. - View Dependent Claims (11, 12, 13, 14, 15)

16. A system for a vehicle, comprising:
-
a traction control system for adjusting powertrain output to reduce wheel slip;
an input device located in said vehicle configured to identify an environmental condition; and
a powertrain controller 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 said input device. - View Dependent Claims (17, 18, 19, 20)
