ON-VEHICLE DEVICE AND ON-VEHICLE SYSTEM

摘要

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
