Vehicle state estimating device, vehicle control device, and vehicle state estimating method

摘要

A vehicle state estimating device for estimating the state amount of the vehicle at high accuracy from the wheel speed irrespective of the change in the vehicle property. A vehicle state estimating device includes a wheel speed detection unit that detects a wheel speed of each vehicle wheel; a vehicle speed detection unit that detects a vehicle speed; and a state amount estimation unit that estimates an unsprung state amount and/or a sprung state amount of the vehicle, based on a wheel speed of reverse phase of left and right wheels based on the wheel speed of each wheel detected by the wheel speed detection unit, and a value obtained by dividing a wheel base of a predetermined front-rear wheel by the vehicle speed detected by the vehicle speed detection unit.

1. A vehicle state estimating device comprising:
a wheel speed detector configured to detect a wheel speed of each wheel of a vehicle; and a control unit including a processor configured to: detect a vehicle speed of the vehicle; and estimate an unsprung state amount and/or a sprung state amount of the vehicle, based on a wheel speed of reverse phase of left and right wheels based on the wheel speed of each wheel detected by the wheel speed detector, and a value obtained by dividing a wheel base of a predetermined front-rear wheel by the vehicle speed.
