Wheel grip factor estimation apparatus |
摘要 |
<p>The present invention is directed to a wheel grip factor estimation apparatus, which includes a steering factor detection unit for detecting at least one of steering factors including a steering torque and steering effort applied to a steering system extending from a steering wheel to a suspension of a vehicle, an aligning torque estimation unit (M6) for estimating an aligning torque produced on at least a wheel of the vehicle on the basis of the steering factor detected by the steering factor detection unit, and a vehicle state variable detection unit for detecting a state variable of the vehicle. The apparatus further includes a wheel factor estimation unit for estimating at least one of wheel factors including a side force and slip angle applied to the wheel on the basis of the vehicle state variable, and a grip factor estimation unit (M12) for estimating a grip factor of at least a tire of the wheel, in accordance with a relationship between the estimated alignment torque and the estimated wheel factor. <IMAGE>The present invention is directed to a wheel grip factor estimation apparatus, which includes a steering factor detection unit for detecting at least one of steering factors including a steering torque and steering effort applied to a steering system extending from a steering wheel to a suspension of a vehicle, an aligning torque estimation unit (M6) for estimating an aligning torque produced on at least a wheel of the vehicle on the basis of the steering factor detected by the steering factor detection unit, and a vehicle state variable detection unit for detecting a state variable of the vehicle.
