ON-BOARD ELECTRONIC CONTROL DEVICE

WIPO Patent Application WO/2018/186483

A1

An on-board electronic control device of an embodiment is an on-board electronic control device operating by receiving power from an on-board battery and provided with: a first power supply path for supplying, to a load, power supplied from the on-board battery via a power supply terminal; a first disconnection part, disposed on the first power supply path, for connecting and disconnecting the first power supply path; a second power supply path for supplying power supplied from the on-board battery via a control power supply terminal and power source IC to a control unit controlling the first disconnection part; a third power supply path for supplying, from a section on the second power supply path between the control power supply terminal and the power source IC, power supplied via the control power supply terminal to a connection point on the first power supply path between the first disconnection part and the load; a second disconnection part, disposed on the third power supply path, for connecting and disconnecting the third power supply path; and a detection unit for detecting a voltage of the first power supply path. Due to the above, redundancies can be effectively built into a power source line using a simple structure.
