Active engine mount system effective in controlling vertical motion of a vehicle body
First Claim
1. An active engine mount system for supporting an engine on a vehicle body, comprising:
- a wheel suspension system supporting said vehicle body on a wheel;
an actuator interposed between said engine and said vehicle body for vertically displacing said engine relative to said vehicle body; and
control means for adjusting a contribution of a mass of said engine to a mass of said vehicle body so as to control a vertical acceleration of said vehicle body according to a given condition of a road surface;
said control means comprising prediction control means for detecting a road condition ahead of said vehicle.

Abstract
An active engine mount system for supporting an engine on a vehicle body is used for controlling the vertical movement of the vehicle body produced by irregularities of the road surface. The engine mount system comprises an actuator interposed between the engine and the vehicle body for applying a vertical force to the vehicle body so that the vertical acceleration of the vehicle body for each given condition of the road surface may be minimized by adjusting a contribution of the mass of the engine to the mass of the vehicle body. The engine mount system may consist of a full active or semi active mount system. By detecting the road condition ahead of the vehicle, a particularly favorable result can be achieved.
