Title:
スリップ率推定装置およびスリップ率制御装置
Document Type and Number:
Japanese Patent JP4538642
Kind Code:
B2
Abstract:
The present invention provides a slip rate estimating device measuring a slip ratio without the need for a body speed and a slip ratio control device using the slip ratio estimating device. A motor torque measured by a torque measuring instrument is input to each of a vehicle model (601) and an SRE (602) that performs calculations including time differentiation of the slip ratio. The vehicle model (601) derives a wheel rotation speed, a wheel rotation acceleration, and a body speed. The vehicle model (601) outputs the wheel rotation speed and the wheel rotation acceleration to the SRE (602). The SRE (602) outputs the slip ratio based on the motor torque, the wheel rotation speed, and the wheel rotation acceleration.
