To provide an in-vehicle system and the like, capable of reducing electric power required for control when a vehicle is in a low current state.SOLUTION: An in-vehicle system comprises: an upstream route connected to a power supply device; downstream routes branching from the upstream route and connect to a load; an upstream in-vehicle device provided in the upstream route and including an upstream semiconductor fuse; and downstream in-vehicle devices provided in the downstream routes, respectively, and including a downstream semiconductor fuse. The upstream in-vehicle device comprises a first control unit for controlling turning on/off the upstream semiconductor fuse. The downstream in-vehicle devices each comprise a second control unit for controlling turning on/off the downstream semiconductor fuse. When a vehicle is in a low current state, the first control unit sets cutoff characteristics of the upstream semiconductor fuse to be lower than when the vehicle is in a normal current state. When the vehicle is in a low current state, the second control unit fixes the downstream semiconductor fuse to be on.SELECTED DRAWING: Figure 1
