Controller for Operation of Vehicle and Control Method for the Same
First Claim
1. A controller for controlling braking force and driving force of a vehicle, in accordance with demand force, the controller comprising:
- a first demand force arithmetic unit for arithmetically calculating first demand force, which includes a factor inducing vibration in suspended components of the vehicle;
a second demand force arithmetic unit for arithmetically calculating second demand force, which substantially excludes the factor inducing vibration in suspended components of the vehicle;
a vibration damping filter for reducing the factor inducing vibration in suspended components of the vehicle from a waveform of the first demand force, thereby producing post-filter demand force; and
an arbitration unit for comparing the post-filter demand force, which is filtered using the vibration damping filter, with the second demand force, thereby selecting one of the post-filter demand force and second demand force as final demand force (y).

Abstract
A controller controls braking force and driving force of a vehicle, in accordance with demand force. The controller includes a first and a second demand force arithmetic units for arithmetically calculating first and second demand force. The first demand force includes a factor inducing vibration in suspended components of the vehicle. The second demand force substantially excludes the factor inducing vibration in suspended components of the vehicle. A vibration damping filter reduces the factor from a waveform of the first demand force, thereby producing post-filter demand force. An arbitration unit compares the post-filter demand force with the second demand force, thereby selecting one of the post-filter demand force and second demand force as final demand force.
