Power consumption - the suppression system for an electronic key - terminal and power consumption - prevention method for an electronic key - terminal

摘要

Power consumption - the suppression system for an electronic key - terminal (200, 200a), comprising the power consumption in an electronic key - terminal (200, 200a) is suppressed, which with a vehicle-mounted device (110) in a vehicle (100) communicates, the system comprising:a position information - obtaining section (210), which is configured in such a way that this locking - position information as information with respect to a position, in which the vehicle (100) with the electronic key - terminal (200, 200a) has been locked, and terminal - position information as information with respect to a position of the electronic key - terminal (200, 200a) is reached; anda power consumption - suppression portion (220), which is configured in such a way that this a power consumption in the electronic key - terminal (200, 200a) is suppressed if a relative distance between the position, in which the vehicle (100) has been locked, as shown by the locking - position information is specified, which by means of the position information - obtaining section (210) are obtained, and the position of the electronic key - terminal (200, 200a), which is indicated by the terminal - positional information, is greater than or equal to a fixed distance (x) is.
