A vehicle body vibration control apparatus separately controls a first vehicle height vibration mechanism provided on a front-wheel side and a second vehicle height vibration mechanism provided on a rear-wheel side. The first and second mechanisms provide first and second damping forces. When it is separately determined that the first and second damping forces should be increased, the first and second damping force are increased by a controller after first and second delay times elapse, respectively. The first and second delay times are selected in accordance with a current vehicle speed so that a front-wheel-side vehicle height vibration and a rear-wheel-side vehicle height vibration are converged toward a mean vehicle height from an identical converging direction and are suppressed to the mean vehicle height at almost the same time.

A vehicle body vibration control apparatus for controlling a first mechanism for suppressing a front-wheel-side vehicle height vibration on a front-wheel side of a vehicle by a first damping force and a second mechanism for suppressing a rear-wheel-side vehicle height vibration on a rear-wheel side

A vehicle body vibration control apparatus for controlling a first mechanism for suppressing a front-wheel-side vehicle height vibration on a front-wheel side of a vehicle by a first damping force and a second mechanism for suppressing a rear-wheel-side vehicle height vibration on a rear-wheel side thereof by a second damping force, said vehicle body vibration control apparatus comprising: vehicle height detecting means for detecting a first vehicle height on the front-wheel side and a second vehicle height on the rear-wheel side; vehicle speed measuring means for measuring a vehicle speed of said vehicle; damping force control means, coupled to said first and second mechanisms and said vehicle height detecting means, for controlling said first damping force so that said first damping force is increased after a first delay time elapses from a time when said first vehicle height exceeds a first predetermined vehicle height range and for controlling said second damping force so that said second damping force is increased after a second delay time elapses from a time when said second vehicle height exceeds a second predetermined vehicle height range; and delay time setting means, coupled to said vehicle speed measuring means and said damping force control means, for setting said first and second delay times which vary depending on said vehicle speed in said damping force control means, so that said front-wheel-side vehicle height vibration and said rear-wheel-side vehicle height vibration are converged toward a mean vehicle height from an identical converging direction and are suppressed to said mean vehicle height at almost the same time.
