Sprung mass damping control system of vehicle
First Claim
1. A sprung mass damping control system of a vehicle, comprising:
- a sprung mass damping controller configured to set a sprung mass damping control amount for damping sprung mass vibrations that occur in a vehicle body in response to an input from a road or a driver-requested torque, the sprung mass damping controller including a first torque converting unit that coverts driver-requested torque into driver-requested wheel torque, a feed-forward control unit, a feedback control unit, and a second torque converting unit that converts an amount of correction of the driver-requested wheel torque into a unit of driving torque, anda drive controller configured to control torque of an engine or of a transmission of the vehicle based on the unit of driving torque to achieve the sprung mass damping control amount, thereby to execute sprung mass damping control,wherein the drive controller is configured to inhibit execution of the sprung mass damping control according to at least one condition of the vehicle which includes a temperature of a motor that drives a throttle valve of the vehicle being greater than a predetermined temperature.

Abstract
A sprung mass damping control system of a vehicle is provided. The sprung mass damping control system includes a sprung mass damping controller that sets a sprung mass damping control amount for damping sprung mass vibrations that occur in a vehicle body in response to an input from a road or a driver-requested torque, and a drive controller that controls an output of a vehicle drive unit so as to achieve the sprung mass damping control amount, thereby to execute sprung mass damping control. The drive controller is configured to permit or inhibit execution of the sprung mass damping control according to at least one of operating conditions of the vehicle, status conditions of the vehicle and driver'"'"'s requests.
