Patent Searching and Data


Title:
VEHICLE-MOUNTED CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/207905
Kind Code:
A1
Abstract:
The purpose of the present invention is to detect a ROM failure inside a microcomputer at the earliest possible stage, and to thereby reduce the risk of occurrence of unintended behavior due to a vehicle continuing to travel with a ROM failure. For this purpose, this vehicle-mounted control device measures an electric current supplied to a read-only storage device, and, when the electric current exceeds a determination threshold, outputs a signal indicating that the read-only storage device may fail in the future.
