Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle starting control device and a control method thereof. In general, a vehicle starting device uses a ignition key to open a door and then inserts the ignition key into a key block of a steering column of a driver's seat in a vehicle interior. The starter circuit of the engine is driven to start the engine. In the conventional vehicle starter, there is no way to prevent theft of the vehicle because there is no way to prevent it when the vehicle door is opened and entered in an illegal manner. In order to solve the above problems, the present invention provides a starting motor relay and a battery relay between a key block provided with a starting key and an optical sensor with a unique pattern, and an input side of an ECU and an engine starting circuit. In the case of a vehicle comprising an injector relay on the inlet side and an ECU for controlling the entire system. By providing the dynamic control device and its control method, the key pattern is recognized by the light sensor of the key block when the door is opened or the engine is started and sent to the ECU and compared with the key pattern stored in the memory. When they do not coincide with each other, the start circuit of the engine is blocked to prevent starting, while the injector relay on the fuel inlet side is blocked to control the fuel from being injected, thereby preventing the engine starting by an illegal method.

Claims (3)

An apparatus for preventing starting of a vehicle, comprising: a start key 11 having a unique pattern imprinted thereon; a key block 12 into which the start key 11 is inserted when the door is opened or started; An optical sensor 13 provided at a predetermined position of the key block 12 to detect an inherent key pattern of the starter key 11 as an optical signal and to transmit it to the ECU 14; ECU 14 for controlling the opening and closing of the starting motor relay 15 and the battery relay 16 connected to the input terminal of the engine starting circuit by recognizing the key pattern to be sent out, and being opened and closed under the control of the ECU 14. A starting motor relay (15) for controlling the opening and closing of the engine starting circuit (15), a battery relay (16) and an injector relay (17) for controlling the injection of fuel. In the control method for preventing the vehicle from starting, when the door is opened (step 20), the key pattern signal of the start key sent from the optical sensor is compared with the key pattern stored in the memory by the ECU (step 21). If the pattern matches each other, proceed to the next step, and if it is wrong, proceed to the start blocking step (step 25), and next, when the start key is inserted (step 22), the key pattern signal of the start key sent from the optical sensor is stored in the ECU. Compared with the key pattern stored in step (step 23), if the two key patterns coincide with each other, the engine is started by starting (step 24). Vehicle start control method. The method of claim 2, wherein the start blocking step 25 comprises turning off the starting motor relay (step 251), turning off the battery relay (step 252), and turning off the injector relay (253). Vehicle starting control method, characterized in that.
