In-vehicle instrument control device
First Claim
1. An in-vehicle instrument control device that is provided for each of a plurality of in-vehicle instruments operated by power from a power source provided in a vehicle, and that controls supply of the power to the corresponding in-vehicle instrument, the device comprising:
- an operation unit that operates the in-vehicle instrument;
a communication unit that communicates with a user authentication unit to obtain a user authentication result;
an in-vehicle instrument control unit that determines whether or not power supply from the power source to the in-vehicle instrument is permitted, based on activation state information of the vehicle and the user authentication result obtained through the communication unit; and
a power source control unit that is provided between the operation unit and the power source control unit,wherein the power source control unit comprises;
a power source supply circuit that starts the supply of the power from the power source to the in-vehicle instrument control unit when a predetermined operation signal is inputted from the operation unit; and
an activation self-holding circuit that continues the supply of the power to the in-vehicle instrument control unit by the power source supply circuit even when operation of the operation unit causing the predetermined operation is completed,wherein when the power source control unit starts the supply of the power from the power source to the in-vehicle instrument control unit, the in-vehicle instrument control unit determines whether or not the power supply is permitted,wherein when the vehicle is activated, the in-vehicle instrument control unit permits the supply of the power, thereby supply the power from the power source to the in-vehicle instrument,wherein when the vehicle is not activated and the user authentication result indicates that the user authentication has succeeded, the in-vehicle instrument control unit permits the supply of the power, thereby supplying the power from the power source to the in-vehicle instrument, andwherein when the vehicle is not activated and the user authentication result indicates that the user authentication has not succeeded, the in-vehicle instrument control unit does not permit the supply of the power.
