Embodiment Construction

[0037] Certain vehicles include one or more actuators that can be adjusted to alter vehicle dynamics. Such actuators may be referred to as kinetic actuators. Examples of dynamic actuators include, but are not limited to, actuators for electronic limited slip differentials, electric power steering systems, automatic braking systems, ride control systems, and aerodynamic systems. The control of the dynamics actuators can be tuned to the driver to vary the skill level and handling type, such as oversteer, understeer, and neutral steer.

[0038] According to the present application, the dynamics control module determines the driver's skill level, such as novice, proficient or professional. The dynamics control module determines the driver's skill level based on the vehicle's lateral and longitudinal acceleration. For example, the dynamics control module may determine the skill level using a map of skill level values ​​indexed by sets of lateral and longitudinal accelerations. H...

Abstract

A vehicle control system includes a first error module that determines a first yaw error based on a difference between a yaw rate of the vehicle and a target yaw rate. A second error module determinesa second yaw error based on the first yaw error and a target yaw error. A target yaw error module sets the target yaw error based on a skill level of a driver of the vehicle. An adjustment module selectively one of increases and decreases a target adjustment when the second yaw error is greater than a first predetermined threshold. An actuator control module, in response to the increase in the target adjustment, actuates a dynamics actuator of the vehicle.
