POWER CONSUMPTION SUPPRESSION SYSTEM FOR ELECTRONIC KEY TERMINAL AND POWER CONSUMPTION SUPPRESSION METHOD FOR ELECTRONIC KEY TERMINAL

摘要

A power consumption suppression system enables effective reduction of power consumption of an electronic key terminal. A position information acquisition section (210) provided on an electronic key terminal (200) acquires locking location information concerning the locking position of a vehicle (100) and terminal location information concerning the position of the electronic key terminal (200). A power consumption suppression section (220) provided on the electronic key terminal (200) reduces the power consumption when the distance between the locking location of the vehicle (100) indicated by the locking location information and the location of the electronic key terminal (200) indicated by the terminal location information is equal to or longer than a prescribed distance.

主权项

1. A power consumption suppression system for an electronic key terminal that suppresses power consumption in an electronic key terminal that communicates with an on-vehicle device in a vehicle, the system comprising:
a location information acquisition section configured to acquire locking location information as information on a location where the vehicle has been locked with the electronic key terminal and terminal location information as information on a location of the electronic key terminal; and a power consumption suppression section configured to suppress power consumption in the electronic key terminal when a relative distance between the location where the vehicle has been locked indicated by the locking location information acquired by the location information acquisition section and the location of the electronic key terminal indicated by the terminal location information is equal to or longer than a prescribed distance.
