A vehicle control device includes: an idle-stop controller configured to control an idle-stop function of a vehicle; and an electric power steering controller configured to assist a steering operation with an electric motor. The electric power steering controller is configured such that, when the electric power steering controller detects a failure by diagnosis, the electric power steering controller controls, based on whether vehicle speed related information including vehicle wheel speed information is receivable and based on whether idle-stop related information related to an idle-stop operation is receivable, an assist operation assisting a steering effort while the idle-stop operation is in progress so that the idle-stop operation may be performed. The idle-stop controller is configured to control the idle-stop function of the vehicle even when the electric power steering controller detects the failure by the diagnosis.

Vehicle control device

Provided is an electric power steering device including: a motor; a drive device that supplies the motor with three-phase alternating current electric power; and a control device that controls the drive device, in which the control device is connected to a first power supply path that supplies power to the control device not via an ignition switch and a second power supply path that supplies power to the control device via the ignition switch, and the control device, in a case of detecting a failing of the first power supply path, operates with power supplied from the second power supply path and makes the motor generate an electromagnetic brake.
