摘要： A method of controlling a traction control system (30) includes continuously adapting a steady state driven wheel speed to reference wheel speed ratio, so that said traction control system can avoid unnecessary actuations (e.g., demanding torque reduction). The continuous adaptation methodology provides traction control robustness to vehicles equipped with a spare tire, or a different final drive such as in the use of aftermarket parts. The method includes a dual rate adaptation that allows both fast adaptation and fine tuning capabilities of the ratio. The method includes comparing the instant driven wheel speed to reference wheel speed ratio to the filtered driven wheel speed to reference wheel speed ratio, to obtain a ratio difference. When the difference is above a threshold, the first filter constant is selected and the first constant is applied to an adaptation filter, resulting in a first filtered and adapted ratio. The traction control system is controlled with the adapted ratio. When the difference is below the threshold, the second filter constant is selected and the selected constant is applied to the adaptation filter, resulting in the second filtered and adapted ratio. The traction control system is controlled with the adapted ratio.

摘要： 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.
