Vehicle theft prevention device
First Claim
1. A vehicle theft prevention device comprising:
- a portable transmitter arranged outside a vehicle for transmitting a first ID code;
a receiver unit for receiving the first ID code transmitted from the portable transmitter and for outputting a second ID code when the first ID code agrees with a preset first reference code; and
an engine control unit for starting an engine control when the second ID code is inputted to the engine control unit and the second ID code agrees with a preset second reference code;
wherein the receiver unit of the vehicle theft prevention device includes a second ID code generator for recording the second reference code to the engine control unit, and an ID writing device for writing the registered second reference code into the receiver unit as the second ID code,wherein data which are inputted for registering the second reference code to the engine control unit are inputted in response to an open/close manipulation of a throttle provided to the vehicle and a standing/storing manipulation of a side stand provided to the vehicle.

Abstract
A theft prevention device makes an ECU operable by transmitting a second ID code to the ECU from a keyset when an input code agrees with a first ID code. A device is provided for inputting a second reference code which is collated with a second ID code provided to a receiver unit of an ECU or a keyset. A device is provided which, when the inputted code and a pre-registered second reference code agree with each other, writes the registered second reference code into the receiver unit as the second ID code. The code which is inputted as the second reference code is inputted based on an opening/closing manipulation of a throttle provided to a vehicle and a plurality of times of standing/storing manipulation of a side stand with and one digit of the code being represented by the number of throttle manipulations during two side stand standing/storing manipulations.

7. A theft prevention device adapted to be used with a vehicle comprising:
-
a portable transmitter for transmitting a first ID code; a receiver unit for receiving the first ID code transmitted from the portable transmitter and for outputting a second ID code when the first ID code agrees with a preset first reference code; and an engine control unit adapted for starting an engine control when the second ID code is inputted and the second ID code agrees with a preset second reference code; wherein the receiver unit of the vehicle theft prevention device includes a second ID code generator for recording the second reference code to the engine control unit, and an ID writing device for writing the registered second reference code into the receiver unit as the second ID code, wherein data which are inputted for registering the second reference code to the engine control unit are inputted in response to an open/close manipulation of a throttle provided to the vehicle and a standing/storing manipulation of a side stand provided to the vehicle. - View Dependent Claims (8, 9, 10, 11, 12)
