Title:
VEHICLE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/145095
Kind Code:
A1
Abstract:
The present invention obtains a vehicle control device using a semiconductor fuse, in which an increase in size of the semiconductor fuse is suppressed and the occurrence of an abnormal current is detected early to be able to shut off the abnormal current. The vehicle control device comprises: a shut-off unit 6 for supplying and shutting off power to a plurality of load devices 4a to 4c; a current detection unit 13c for detecting current flowing through the plurality of load devices 4a to 4c; and a temperature detection unit 13d for detecting the temperature of the shut-off unit 6. The vehicle control device further comprises a drive control unit 13b which, when the temperature of the shut-off unit 6 detected by the temperature detection unit 13d exceeds a predetermined value, controls and restricts, on the basis of the priorities set for the respective plurality of load devices 4a to 4c, the operations of the load devices 4a to 4c having lower priorities.
