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

The 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. The second error module determines a second yaw error based on a difference between the first yaw error and the target yaw error. The target yaw error module sets a target yaw error based on a skill level of a driver of the vehicle. When the second yaw error is greater than the first predetermined threshold, the adjustment module selectively increases or decreases one of the target adjustment amount. An actuator control module actuates a dynamics actuator of the vehicle in response to the increase in the target adjustment.
