In-vehicle control system
First Claim
1. An in-vehicle control system mounted in a vehicle, which is connectable to a charging facility through a charging cable including a double-wire type facility-side communication line and a charging power cable connected with a facility-side terminal circuit and has a battery chargeable from the charging facility through the charging power cable, the in-vehicle control system comprising:
- a double-wire type vehicle-side communication line connectable to the facility-side communication line and including three vehicle-side terminal circuits;
plural electronic devices connected to the vehicle-side communication line and capable of communication through the vehicle-side communication line by using a differential voltage, the plural electronic devices including a charging control device capable of communication with the charging facility through the vehicle-side communication line and the facility-side communication line by using the differential voltage; and
changeover members provided in correspondence to the three vehicle-side terminal circuits and individually validating and invalidating the three vehicle-side terminal circuits, respectively,wherein the changeover members validate two of the three vehicle-side terminal circuits and invalidate a remaining one of the three vehicle-side terminal circuits, when the facility-side communication line is disconnected from the vehicle-side communication line, andthe changeover members validate one of the three vehicle-side terminal circuits and invalidate remaining two of the three vehicle-side terminal circuits, when the facility-side communication line is connected to the vehicle-side communication line.

Abstract
An in-vehicle control system is mounted in a vehicle, which is connectable with a charging station through a charging cable and provided with a battery chargeable from the charging station through the charging cable. The vehicle includes a double-wire type communication line provided with a charger-side terminal circuit. The in-vehicle control system includes a first communication line and a second communication line, which are connectable to the communication line of the charging cable and provided with three terminal circuits. The in-vehicle control system further includes a first ECU and a second ECU, which are connected to the first communication line and the second communication line. When a charging plug is connected to a charging port, the first ECU and the second ECU validate the first terminal circuit and invalidate the second terminal circuit and the third terminal circuit.
