Document Type and Number:
WIPO Patent Application WO/2019/176316
Kind Code:
A1
Abstract:
Provided is a control device for an on-vehicle apparatus, in which fluctuation of a ground potential is suppressed, and damage due to deviation of earth current can be suppressed when a ground part of a vehicle has an abnormality. The control device for an on-vehicle apparatus is provided with an actuator, and is configured to feed power from first and second power sources to first and second microprocessors and first and second drive circuits through first and second power feed paths, respectively, so as to drive the actuator by means of the first and second drive circuits. In the control device, respective negative electrodes of the first and second power sources are electrically connected to a common ground part. Further, first and second negative electrodes of the first and second power sources are connected to the common ground part respectively through independent first and second connector parts.
