<P>PROBLEM TO BE SOLVED: To provide an engine starting system that can suppress the occurrence of vibration even when a failure that a clutch can not be disconnected occurs at the starting process of an engine mounted on a hybrid vehicle. <P>SOLUTION: The engine starting system, when a failure F that an electromagnetic clutch can not be disconnected after semi-engagement operation to increase a clutch torque Tqc is performed, reduces a motor torque Tqm at a time t3 when an engine side rotational speed Ne of the electromagnetic clutch reaches the rotational limit not exceeding an rotational speed Nin on a motor generator side. <P>COPYRIGHT: (C)2013,JPO&INPIT |
