US 2019/0101045 A1 · CONTROL DEVICE FOR VEHICLE

Abstract

A control device for a vehicle includes a grille shutter ECU that is connected to a LIN communication line and controls driving of a grille shutter, and an engine ECU that is connected to the LIN communication line so as to be able to establish communication with the grille shutter ECU. In the case of detecting an abnormality in the communication, if a predetermine threshold time or more has elapsed since a start of the vehicle, and if cumulative time that a detection result of a vehicle speed sensor is equal to or more than a predetermined vehicle speed threshold value, is equal to or more than a cumulative threshold value, and a number of starts of the vehicle is equal to or more than a predetermined trip number, the engine ECU determines that the detected abnormality is a failure in the LIN communication.
