Theft prevention apparatus of leisure vehicle
First Claim
1. A theft prevention apparatus of a leisure vehicle that is configured to enable the leisure vehicle to be steered when a user identification code transmitted by radio matches a correct user identification code, the apparatus comprising:
- a portable device configured to transmit the user identification code by radio;
a communication device that is equipped in the leisure vehicle and is configured to receive the user identification code transmitted from the portable device, with electric power being supplied to the communication device;
an electric power supply loaded in the leisure vehicle;
a hand-operated switch that is disposed on a power line coupling the electric power supply to the communication device and is configured to be turned to an on-state or an off-state to or not to permit the electric power to be supplied from the electric power supply to the communication device; and
a controller including a memory configured to store the correct user identification code, the controller being coupled to the communication device through a signal line and being configured to determine whether or not the user identification code received from the communication device matches the correct user identification code stored in the memory and to enable the leisure vehicle to be steered when it is determined that the received user identification code matches the correct user identification code.

16. A theft prevention apparatus of a leisure vehicle that is configured to enable the leisure vehicle to be steered when a user identification code transmitted by radio matches a correct user identification code, the apparatus comprising:
-
a portable device configured to transmit the user identification code by radio;
a communication device that is equipped in the leisure vehicle and is configured to receive the user identification code transmitted from the portable device;
right and left directional antennae that are disposed on right and left sides of the leisure vehicle such that a rider'"'"'s seat is located in a region where predetermined angular ranges of the antennae in which the antennae are able to receive radio wave overlap with each other, the antennae being coupled to the communication device through a communication line and being configured to be able to receive the signals from the portable device in a case where the portable device is present within the predetermined angular ranges;
a comparator that is equipped in the leisure vehicle and is configured to compare intensities of the signals received from the right and left antennae; and
a controller configured to determine whether or not the user identification code transmitted from the portable device matches the correct user identification code when a difference between the intensities of the signals received from the right and left antenna is zero or within a predetermined value. - View Dependent Claims (17)
