SPECIFICATION INFORMATION ESTIMATING DEVICE AND VEHICLE
First Claim
1. A specification information estimating device which estimates the steering gear ratio of a vehicle, the device comprising:
- a traveling data acquisition unit which acquires the steering angle and the yaw rate of the vehicle during traveling; and
a steering gear ratio estimation unit which estimates the steering gear ratio on the basis of the steering angle and the yaw rate acquired by the traveling data acquisition unit.

Abstract
Disclosed is a specification information estimating device which estimates the steering gear ratio n of a vehicle. A specification information estimating device includes a steering angle sensor 26 and a yaw rate sensor 51 which acquire the wheel steering angle St and the yaw rate Yr of the vehicle during traveling, and an ECU 4 which estimates a steering gear ratio n on the basis of the wheel steering angle St and the yaw rate Yr acquired by the steering angle sensor 26 and the yaw rate sensor 51. Therefore, it is possible to estimate the steering gear ratio n of each vehicle without using a stability factor KH.
