<P>PROBLEM TO BE SOLVED: To provide a control method for a switchable power train mount suitable for a hybrid electric vehicle (HEV). <P>SOLUTION: A control part changes vibration-resistant mode in the switchable power train mount 56 using a vehicle operation condition sensor and a threshold value selected in advance. The vehicle sensor and the threshold value selected in advance determine that an engine is in any mode of stopping, idle running, and operation. When a control device determines that the engine is in idle running mode and there is high possibility that it stays in the mode based on the determination, the control device gives a command that the engine stays in idle running mode to the switchable mount. A switching means for the switchable mount can use a three-way negative pressure solenoid valve (VSV) 62 or a mechanical or electrical switch. When using the VSV, the VSV is attached to the control device 46 for communication, a negative pressure line 60 connects the VSV 62 with the switchable mount 56, and a second negative pressure line 64 connects the VSV 62 with an engine intake manifold 66. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
