TIRE SENSOR-BASED VEHICLE STATE ESTIMATION SYSTEM AND METHOD

DRIVE January 11, 2017
Source

A vehicle state estimation system and method is disclosed. The system comprises a vehicle supported by at least one tire, the tire being preferably mounted to an axle, the vehicle operating in transient maneuver states or non-transient maneuver states throughout operational maneuvers of the vehicle; at least one tire-based sensor mounted to the at least one tire and operative to generate tire-based sensor data;_and at least one vehicle-based sensor mounted to the vehicle and operative to generate vehicle-based sensor data. Furthermore, the system may comprise, in one aspect, an observer model operative to make cornering stiffness estimates from the tire-based sensor data and the vehicle-based sensor data throughout the operational maneuvers of the vehicle; and a cornering stiffness identifier operative to extract and output transient-state cornering stiffness estimates from the observer model cornering stiffness estimates throughout the operational maneuvers of the vehicle.
