Abstract: PROBLEM TO BE SOLVED: To accurately determine whether a Current Interrupt Device (CID) is operated on a vehicle mounting a storage apparatus configured to include the CID.SOLUTION: A controller 40 is mounted on a vehicle having the storage apparatus configured to include the CID, a driver device to generate a vehicle driving power using a power from the storage apparatus, and an auxiliary machine to consume the power from the storage apparatus. When the CID is operated (disconnected), no current flows through the storage apparatus. The controller 40 includes a temporary determination part 40A and a formal determination part 40B. The temporary determination part 40A temporarily determines whether the CID is disconnected based on a variation in a voltage VL to be input from the storage apparatus to the driver device. When the temporary determination part 40A makes a temporary determination as the "CID Disconnection", the formal determination part 40B performs a VL variation control to intentionally change the voltage VL by controlling the driver device or the auxiliary machine, and formally determines whether the CID is disconnected based on a variation amount of current Ib to be output from the storage apparatus during the VL variation control.

Abstract: PROBLEM TO BE SOLVED: To provide a motor drive system capable of detecting an inverter one-phase open fault. SOLUTION: A controller compares the detecting value of the DC current of a DC power supply by a current sensor and the estimate of the DC current arithmetically operated on the basis of the power incomings and outgoings of the whole motor drive system (steps S01 to S03). The controller detects the fluctuation of the DC current when a deviation between both the detecting value and the estimate exceeds a threshold (a YES decision time at the step S04). The controller decides whether the fluctuating frequency of the arithmetically operated DC current is synchronized with the rotational speed of a motor generator (the steps S06 to S08) when the fluctuating frequency of the DC current is operated arithmetically (the step S05). When the fluctuating frequency of the DC current is synchronized with the rotational speed of the motor generator in this case, the controller detects the generation of the one-phase open fault in an inverter (the steps S09 and S10).
