TIRE CORNERING STIFFNESS ESTIMATION SYSTEM AND METHOD

摘要

A tire cornering stiffness estimation system and method is disclosed. The system (10) comprises a vehicle (12) supported by at least one vehicle tire (14) mounted to a hub, the vehicle tire (14) having a tire cavity (22), a ground-engaging tread (16) and a plurality of tire-specific measureable parameters; a plurality of tire-affixed sensors (20) mounted to the tire (14) for operably measuring the tire-specific parameters to generate tire-specific information; at least one accelerometer mounted to the hub and generating a hub accelerometer signal; and a model-based tire cornering stiffness estimator being operable to generate a model-derived tire cornering stiffness estimation (30) based upon the hub accelerometer signal and the tire-specific information or the hub accelerometer signal adapted by the the tire-specific information.
