Title:
CONTROL DEVICE FOR ON-VEHICLE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/176299
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 actuators, 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 actuators 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 sensors for detecting current or voltage between the vehicle body ground and the respective negative electrodes of the first and second power sources, are provided, and, when an abnormality is detected in the current or voltage, the first and second drive circuits are controlled by means of the first and second microprocessors so as to restrict power to be fed to the actuators.
