Title:
ELECTRONIC KEY SYSTEM, ON-VEHICLE DEVICE, MOBILE TERMINAL
Document Type and Number:
Japanese Patent JP2016079590
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electronic key system, an on-vehicle device, and a mobile terminal that enable a user to recognize that a parking position of a vehicle is at a place susceptible to jamming, after parking the vehicle and before getting off.SOLUTION: When a parking determination part F3 determines that the vehicle has shifted to a parking state, a jamming determination part F4 determines whether a communication between an on-vehicle device and a mobile terminal is jammed. More specifically, jamming is determined to be present when either or both of a signal intensity of a signal received by a UHF receiving part and a signal intensity of a signal received by an LF receiving part exceeds a prescribed threshold value. When the jamming determination part has determined that jamming is present, information on the presence of jamming is displayed on a vehicle-side display part and a mobile terminal-side display part.SELECTED DRAWING: Figure 5
