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 a final demand force.

Abstract
A controller controls braking force and driving force of a vehicle, in accordance with demand force. The controller includes a first and 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.

2. 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 first arbitration unit for comparing the first demand force with the second demand force, thereby selecting one of the first demand force and second demand force; a vibration damping filter for reducing the factor inducing vibration in suspended components of the vehicle from a waveform of the one of the first demand force and second demand force selected using the first arbitration unit, thereby producing post-filter demand force; and a second arbitration unit for comparing the post-filter demand force, which is filtered using the vibration damping filter, with the second demand force when selected using the first arbitration unit, thereby selecting one of the post-filter demand force and the second demand force as a final demand force, wherein the second arbitration unit selects the post-filter demand force which is filtered using the arbitration damping filter, as the final demand force, when the first arbitration unit selects the first demand force; and the second arbitration unit selects the second demand force as the final demand force without using said filter, when the first arbitration unit selects the second demand force. - View Dependent Claims (3, 4, 5, 6)

7. A method for controlling braking force and driving force of a vehicle in accordance with demand force, the method comprising:
-
firstly calculating first demand force, which includes a factor inducing vibration in suspended components of the vehicle; secondly calculating second demand force, which substantially excludes a factor inducing vibration in suspended components of the vehicle; 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 comparing 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. - View Dependent Claims (15, 16)

8. A method for controlling braking force and driving force of a vehicle, in accordance with demand force, the method comprising:
-
firstly calculating first demand force, which includes a factor inducing vibration in suspended components of the vehicle; secondly calculating second demand force, which substantially excludes a factor inducing vibration in suspended components of the vehicle; firstly comparing the first demand force with the second demand force, thereby selecting one of the first demand force and second demand force; 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 secondly comparing the post-filter demand force with the second demand force, thereby selecting one of the post-filter demand force and the second demand force, as a final demand force, wherein the post-filter demand force is selected as the final demand force in the step of secondly comparing, when the first demand force is selected in the step of firstly comparing; and the second demand force is selected as the final demand force as it is in the step of secondly comparing, when the second demand force is selected in the step of firstly comparing. - View Dependent Claims (9, 10, 11, 12)
