Document Type and Number:
Japanese Patent JP6407807
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress switching between notification and notification stop of a notification part according to a temperature change following travel.SOLUTION: A controller of a transmitter measures as a transit time, a time when an acceleration detected by an acceleration sensor becomes a threshold for travel determination or higher. The controller transmits a transmitter signal in a first transmission frequency until the transit time reaches a low-frequency transmission time t1, and transmits the transmitter signal in a second transmission frequency having a higher frequency than the first transmission frequency from the low-frequency transmission time t1 until a set time t2.SELECTED DRAWING: Figure 4
