<p>In a hybrid vehicle (100), first, an engine (5) is locked by an engine shaft locking mechanism (13). A first motor (MG1) is connected to a first inverter circuit (Cmg1) and a second motor (MG2) is connected to a second inverter circuit (Cmg2) and then both the motors are operated, and the output characteristics of each motor are obtained. Further, the first motor (MG1) is connected to the second inverter circuit (Cmg2) and the second motor (MG2) is connected to the first inverter circuit (Cmg1) and then both the motors are operated, and the output characteristics of each motor are obtained. Based on the obtained output characteristics, it is determined whether each of the motors and the inverter circuits is normal or not.</p> |
