摘要： A method for controlling a vehicle includes applying torque to a set of tires to cause the vehicle to move along a surface, reducing an amount of downward force applied to the surface by a first tire from the set of tires using an active suspension component, and actuating the first tire to control the dynamic response of the first tire relative to the surface. The method also includes determining a traction force of the first tire relative to the surface at each of multiple values for the dynamic response of the first tire relative to the surface, and determining a maximum available traction force based on the multiple values of the dynamic response and the corresponding values for the traction force. The method also includes determining a friction parameter based on the maximum available traction force, and controlling an operation of the vehicle based on the friction parameter.

摘要： Aspects of the present disclosure involve a method for determining a road vehicle velocity and slip angle. The current disclosure presents a technique for identifying a vehicle's velocity and slip angle, in the vehicle's coordinate frame. In one embodiment, two or more sensors are orthogonally located on the underside of the vehicle in order to obtain longitudinal and lateral velocity information for slip angle determination. In another embodiment, the two or more sensors can include an array of elements for beam steering and receiver beamforming. Spatial diversity is leveraged in identifying at least a slip angle and/or velocity of the vehicle. Doppler mapping is used as a means for slip angle determination and the clutter ridge of the Doppler map is embraced for identifying the slip angle.

摘要： A control system for a vehicle includes an internal vehicle reference model that determines reference states for the vehicle that represent an expected vehicle response, sensors that determine measured states for the vehicle, and a vehicle motion control system that determines desired states for the vehicle. A stability determining module identifies a reference deviation between the reference states and the measured states, identifies a desired deviation between the desired states and measured states, and outputs a command for reducing the reference deviation and the desired deviation. Actuators are operable to reduce the reference deviation and the desired deviation in response to the command.
