Document Type and Number:

Japanese Patent JP2014162307

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To enable driving of a fan motor highly efficiently and detecting of the abnormality of the fan motor from the vehicle side.SOLUTION: A system comprises: a motor control device 21 that includes a switching element 22 and converts DC power supplied from a high-voltage power source 4 into three-phase AC power and supplies a three-phase motor 3 with the power; a first control unit 24 for controlling the motor control device 21; an insulated CAN driver 82 that operates on power supplied from a low-voltage power source 5 and exchanges information with a vehicle-side vehicular ECU 6, a host to a vehicular cooling fan motor-inverter system 2; and an insulation unit 8 for electrically insulating between a low-voltage system having power supplied from the low-voltage power source 5 and a high-voltage system having power supplied from the high-voltage power source 4. Further, in the case of an abnormality being detected on the switching element 22, the first control unit 24 outputs abnormality information with which the vehicle-side vehicular ECU 6 is notified of an abnormality present in controlling the three-phase motor 3 via the insulated CAN driver 82.
