A vehicle control device having a redundant configuration includes a task switching function unit configured to switch tasks to be executed when an abnormality is detected. The task switching function unit being configured to, when a diagnostic function unit determines that an abnormality has occurred in a unit of a host system, cause the unit of the failed system to stop calculation of control variable, and stop drive control for a control object, and then execute calculation other than the calculation of the control variable of the host system, and the drive control for an electric motor, so that the calculation unit of the failed system can take over at least a part of calculation of a normal system or another on-vehicle device.
