Development of Active Control Engine Mount System for Reduction of Resonance Vibration at Engine Restart

Article of Honda R&D Technical Review Vol.26 No.2

Summary

Active Control Engine Mounts are in mass production as a technology for the reduction of noise and vibration in complete vehicles associated with the use of V6 variable-cylinder engines. The research discussed in this paper developed a next-generation active control engine mount system that reduces vibration in complete vehicles occurring when the engine is restarted following idle stop or EV operation in a hybrid system. The fact that the timing of the powerplant resonance vibration that occurs at engine restart correlates strongly with the angle of rotation of the crankshaft was focused on, and a new control method was developed that predicts the timing and magnitude of resonance vibration and cancels it. In addition, the development of a system able to respond to high-amplitude engine resonance vibration has increased noise and vibration performance at engine restart following idle stop or EV operation in a hybrid system.
