ON-VEHICLE DEVICE AND ON-VEHICLE SYSTEM

PROBLEM TO BE SOLVED: To provide an on-vehicle device and an on-vehicle system capable of communicating with other on-vehicle device properly when a battery voltage of a vehicle has reduced.SOLUTION: An on-vehicle device comprises: a communication unit for communicating with another on-vehicle device; and a control unit which is communicably connected with the other on-vehicle device via the communication unit, and when a power source voltage is equal to or higher than a first threshold, shifts to an operation mode in which control on a control object is performed. The control unit can communicate with the other on-vehicle device via the communication unit if the power source voltage is equal to or higher than a second threshold even when the power source voltage is less than the first threshold.SELECTED DRAWING: Figure 1 【課題】車両のバッテリー電圧が低下した場合において他の車載装置との通信を適切に行うことができる車載装置および車載システムを提供すること。【解決手段】本発明の車載装置は、他の車載装置と通信する通信部と、通信部を介して他の車載装置と通信可能に接続され、電源電圧が第１閾値以上の場合に制御対象への制御を行う動作モードになる制御部とを備える。制御部は、電源電圧が第１閾値未満であっても第２閾値以上であれば、他の車載装置と通信部を介して通信可能であることを特徴とする。【選択図】図１
