Beschreibung
Zusammenfassung:	A control device for an on-board device including an actuator is configured to: supply power to a first microprocessor and a first driver circuit from a first power source through a first power supply path; supply power to a second microprocessor and a second driver circuit from a second power source through a second power supply path; and use the first and second driver circuits to drive the actuator. In this control device, the negative electrodes of the first and second power sources are electrically connected to a common ground portion. Furthermore, the control device includes a first and second sensor for measuring current or voltage between the vehicle body ground and the negative electrodes of the first and second power source, respectively. When detecting an abnormal current or voltage, the first and second microprocessors control the first and second driver circuits so as to place a limit on power supply to the actuator.
