Abstract

A control circuit board has a plurality of connectors that can connect each control module circuit board to control a plurality of in-vehicle equipment. A power supply circuit board has a power supply circuit that controls a power supply from a battery to a controlled equipment of the control module circuit boards connected with each connector. The control circuit board and the power supply circuit board are electrically connected and accommodated in a case. When the control module circuit boards are connected with any connector of the control circuit board, the power supply circuit is controlled by the control module and it becomes possible to control the controlled equipment such as engines.

Claims

1. An electronic control device that can control a plurality of in-vehicle equipment, comprising:

a first circuit board that has a plurality of connectors that can connect control modules configured to control any of a plurality of the in-vehicle equipment;

a second circuit board that has a power supply circuit for controlling a power supply to a controlled equipment that is the in-vehicle equipment, which is a controlled target for the control modules connected with the connectors; and

a case where the electrically connected first and second circuit boards are accommodated;

wherein, when the control modules are connected with the connectors of the first circuit board, the power supply circuit is controlled by the control modules and it becomes possible to control the controlled equipment.

2. The electronic control device according to claim 1,

wherein, the control modules are connected with a plurality of the connectors at the same time so that it becomes possible to control the controlled equipment of the control module.

3. The electronic control device according to claim 1,

wherein, at least one of an engine, a transmission, a door lock mechanism, or a security device is included in the in-vehicle equipment.

4. The electronic control device according to claim 1,

wherein, at least one of a DC-DC converter, a protection circuit of the power supply, or a connection-cutoff circuit of the power supply is provided in the power supply circuit.
