Abstract
Methods and system are provided for controlling a vehicle. The methods and systems read sensors and estimate pneumatic trail for a tire of the vehicle based on the sensor readings. The methods and systems determine presence or absence of a tire lateral saturation condition based on a comparison of the estimated pneumatic trail for the tire of the vehicle with a pneumatic trail threshold indicative of a tire lateral saturation condition. When the tire lateral saturation condition is present, the methods and systems determine a control value and use the control value as an input to a vehicle control module. The vehicle control module is responsive to the tire lateral saturation condition based on the control value.
