ON-VEHICLE ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To suppress a decrease in residual capacity of a battery even when a vehicle-mounted type electronic apparatus is mounted to a vehicle constantly supplied with power from an accessory socket.SOLUTION: A vehicle-mounted type electronic apparatus mounted to a vehicle comprises: a detection section; a power supply generating section; a battery; and determination means. The detection section detects the first electric power being supplied from a power supply section of the vehicle to the vehicle-mounted type electronic apparatus. The power supply generating section generates driving power supply for driving the vehicle-mounted type electronic apparatus from one of the first electric power and the second electric power supplied from the battery. The determination means determines whether or not a system of the vehicle is activated. When power supply of the first electric power is detected by the detection section and the system of the vehicle is determined to not be activated by the determination means, the power supply generating section generates the driving power supply by using the second electric power.SELECTED DRAWING: Figure 3
