Title:
SLIP RATIO ESTIMATING DEVICE AND SLIP RATIO CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/029524
Kind Code:
A1
Abstract:
A slip ratio estimating device for measuring the slip ratio without using the
speed of a vehicle body and a slip ratio control device using the slip ratio estimating
device are provided. A motor torque measured by a torque measurer is input into
a vehicle model (601) and an SRE (602) which calculates the time derivative of
the slip ratio. The vehicle model (601) derives the rotational speed of a wheel,
the rotational acceleration of the wheel, and the speed of the vehicle body, and
outputs the rotational speed of the wheel and the rotational acceleration of
the wheel to the SRE (602). The SRE (602) outputs the slip ratio according to the
motor torque, the rotational speed of the wheel, and the rotational acceleration
of the wheel.
