PROBLEM TO BE SOLVED: To provide an on-vehicle communication system and an on-vehicle control device capable of detecting release of connection of a connector which is performed before connecting an unauthorized device.SOLUTION: An on-vehicle communication system comprising plural on-vehicle control devices 3 connected to a communication line 2 with a connector 4, comprises a detection unit. When connection of the connector 4 is released, the detection unit detects voltage which is output by pressure acting on a piezoelectric element disposed on the connector 4, thereby detecting release of connection of the connector 4.SELECTED DRAWING: Figure 2 |
