Patent Images
1. A burglarproof device for a vehicle comprising:
- a portable transmitter having a first switch which transmits a preset first ID code;
an activation unit for the vehicle which receives the first ID code from the portable transmitter and collates the first ID code with a prestored second ID code, such that a locked state of a vehicle operation device for the vehicle is released when the activation unit receives the first ID code; and
an engine operation restraining unit which disables an engine operation based on a signal from the activation unit,wherein the signal from the activation unit is sent after the vehicle operation device has been released in response to the receipt of the first ID code by the activation unit, andwherein the signal to disable the engine operation is sent by the activation unit if a time period between the release of the vehicle operation device by the activation unit and a detection of a start of the engine operation exceeds a first time period.

11. A method for preventing a burglary in a vehicle comprising:
-
transmitting a preset first ID code using a portable transmitter; receiving the first ID using a receiver; collating the first ID received by the receiver with a prestored second ID code prestored in the receiver, such that a locked state of a vehicle operation device for the vehicle is released when the receiver receives the first ID code; and disabling an engine operation based on a signal representing a result of the collation, wherein the signal representing the result is sent after the vehicle operation device has been released in response to the received first ID code, and wherein the signal to disable the engine operation is sent by the activation unit if a time period between the release of the vehicle operation device by the activation unit and a detection of a start of the engine operation exceeds a first time period. - View Dependent Claims (12, 13, 15)

16. A burglarproof device for a vehicle comprising:
-
a portable transmitter having a first switch which transmits a preset first ID code; an activation unit for the vehicle which receives the first ID code from the portable transmitter and collates the first ID code with a prestored second ID code, such that a locked state of a vehicle operation device for the vehicle is released when the activation unit receives the first ID code; and an engine operation restraining unit which disables an engine operation based on a signal from the activation unit, wherein the signal from the activation unit is sent after the vehicle operation device has been released in response to the receipt of the first ID code by the activation unit, and wherein the transmission of the preset first ID code by the portable transmitter to the activation unit is a final communication between the portable transmitter and the activation unit that causes the activation unit to release the vehicle operation device and, after a predetermined time from the reception of the preset first ID code, the final communication further causes the activation unit to send the signal to the engine operation restraining unit to disable the engine operation. - View Dependent Claims (17)
