A control unit having an immobilizer function includes a circuit for transmitting a request signal within a predetermined range. After receiving a reply signal from an electronic key in response to this request signal once and allowing a movable body to move, when a reply signal to the periodically sent request signal is not received, it is determined that the electronic key is out of the range, and it is assumed that the key has been dropped. A monitor section outputs a warning signal and transmits the warning signal to the navigation unit. A navigation unit, in response to the warning signal, stores the location at that time as the positional information on the electronic key. The navigation unit also displays a map showing the location of a key based on positional information on the electronic key. With this system, a lost electronic key may be readily located.

The present application claims priority under 35 U.S.C. §119 to Japanese Patent Application No. 2005-208412, filed Jul. 19, 2005, the entire contents of which are hereby incorporated by reference.
1. Field of the Invention
The present invention relates to a monitoring apparatus for an electronic key and a displaying apparatus for positional information on an electronic key. Particularly, it relates to a monitoring apparatus for an electronic key and a displaying apparatus for positional information on an electronic key, which are capable of displaying positional information on the electronic key in a GPS navigation unit mounted on a movable body.
The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
FIG. 1 is a block diagram showing a system configuration of a displaying apparatus for positional information on a key according to an embodiment of the present invention;
FIG. 2 is a perspective view of an all-terrain vehicle in which a displaying apparatus for positional information on a key according to an embodiment of the present invention is mounted;
FIG. 2 is a perspective view of an ATV equipped with a displaying apparatus for positional information on an electronic key according to the present invention. ATV 100 is a vehicle suitable for rough-terrain driving, which is provided with major diameter wheels 101, an under cover 102, and a four-wheel drive mechanism coupled to an engine E.
A meter unit 107 is prepared in the center section of a handle 106, on top of which a GPS receiving antenna 103 is arranged in a standing condition. Although ATV 100 is often used in a rough terrain where a posture during driving changes greatly, employing a helical-type antenna as the receiving antenna 103 allows a GPS electric wave to be received excellently irrespective of the changes of the posture.
At a front part and a rear part of the vehicle, a front carrier 104 and a rear carrier 108 are mounted, respectively. In an upper back part of the front carrier 104, there is mounted a navigation box 105 housing a navigation unit, which displays a location of ATV 100 based on the GPS electric wave and map information. This ATV 100 employs a keyless entry wherein an ID transmitted by the electronic key is recognized via communication with the electronic key, thereby allowing the engine to be started and the handle to be operated.
