Abstract
A vehicle control system includes a function that relates (i) pairs of lateral and longitudinal acceleration values to (ii) skill values. A skill module: receives both (i) a lateral acceleration of the vehicle and (ii) a longitudinal acceleration of the vehicle; and, using the function, determines a skill value of a driver of the vehicle based on both (i) the lateral acceleration of the vehicle and (ii) the longitudinal acceleration of the vehicle. A skill level module determines a skill level of the driver of the vehicle based on the skill value. An actuator control module, based on the skill level of the driver, selectively actuates a dynamics actuator of the vehicle.
