VEHICLE CONTROL DEVICE AND VEHICLE CONTROL METHOD

摘要

A vehicle control device includes a variable-damping-force shock absorber, a sprung mass vibration damping control, an unsprung mass vibration damping control device, and a damping force control device configured to calculate a damping force control amount on the basis of a sprung-mass vibration damping control amount when the sprung-mass vibration damping amount is greater than an unsprung-mass vibration damping control amount, calculating a damping force control amount on the basis of the unsprung-mass vibration damping amount so as to maintain the damping force distribution factor when the sprung-mass vibration damping amount is equal to or less than the unsprung-mass vibration damping amount, and controlling the damping force of the variable-damping-force shock absorber.

1. A vehicle control device comprising:
a variable-damping-force shock absorber configured to adjust damping force; a sprung mass vibration damping control configured to calculate a sprung-mass vibration damping control amount, which is a damping force to minimize sprung mass vibration; an unsprung mass vibration damping control device configured to calculate an unsprung-mass vibration damping control amount, which is a damping force to minimize unsprung mass vibration; and a damping force control device configured to calculate a damping force control amount on the basis of the sprung-mass vibration damping control amount when the sprung-mass vibration damping amount is greater than the unsprung-mass vibration damping control amount, calculate the damping force control amount on the basis of the unsprung-mass vibration damping amount so as to maintain the damping force distribution factor when the sprung-mass vibration damping amount is equal to or less than the unsprung-mass vibration damping amount, and control the damping force of the variable-damping-force shock absorber.
