Description

Automobile antitheft device.

The present invention relates to an anti-theft device of a vehicle, and in detail, when the passwords match, the power is supplied to the starting motor so that the engine can be started. If the passwords do not match, the vehicle cannot be started. If the passwords match the equalization of the difficult parking brakes, an additional electronic clamp is installed to prevent the parking brakes from unlocking if the passwords do not match.

Generally, various anti-theft devices or anti-theft alarms are installed in the vehicle, but most of them are conventional technologies, so it is difficult to avoid theft of vehicles unless they are cleverly installed.

In addition, some license plate identifiers are used, but they are not bulky and portable, and if only the front license plate is replaced, they become useless. Also, DGPS devices using satellites can be developed to identify the movement and location of vehicles. Difficult to attach to the equipment, such as an antenna exposed to the difficulty of installation and the additional cost burden, such as the satellite fee, there is a problem that it takes a considerable time for practical use.

In addition, a "remote start control apparatus and method thereof" for remotely controlling the start of a vehicle by using a start means for performing a start or start off function by a start control signal is disclosed in Korean Patent No. 97-006871. However, since the vehicle is remotely turned on / off, when an error occurs in the engine or the control CPU while driving, there is a problem in that the vehicle is stopped immediately, resulting in a collision accident due to a subsequent vehicle.

In addition, by using the engine control means for controlling the engine by the burglar warning means and the power cut-off means for turning off the power supplied to the ignition device for controlling the ignition timing according to the start and running of the engine under the control of the engine control means Although "vehicle theft prevention system" to prevent theft of the vehicle has been disclosed in the domestic patent No. 98-21952, but this also prevents theft by blocking the running of the vehicle by controlling the engine ignition device, but the circuit configuration is complicated In addition to high cost, there is a problem that causes malfunction.

In addition, there is an anti-theft device that prevents the parking brake lever from lowering by installing the locking mechanism of the click structure on one side of the parking brake lever, but if the easily accessible parking brake lever is damaged, the parking brake is unlocked. There is a problem such as being easily stolen.

Therefore, the present invention aims to prevent the start of the car if the password does not match by supplying power to the starter motor if the password matches.

In addition, by installing an electronic lock device in the equalized portion of the parking brake is difficult to access, the purpose is to prevent theft of the car in advance by allowing the parking brake to be unlocked if the password is matched.

In addition, in the case of hydraulic parking brake or pneumatic parking brake, install a solenoid valve in the middle part of the hydraulic hose or pneumatic hose of the brake system, and if the password is matched, open the solenoid valve to allow the hydraulic or pneumatic flow. If the code does not match, the solenoid valve will be closed to prevent theft of large vehicles such as buses, trucks and heavy equipment.

The present invention, in contrast to the anti-theft device that is conventionally installed in some automobiles, cuts off the operating power of the starting motor without shutting off the power, and locks the equalization for the parking brake by using the lock by the electronic clutch. Since the driver's anti-theft function is operated by using the remote control, emergency signal transmission function, emergency signal transmission blocking function, anti-theft function, anti-theft release function, door lock function, door lock are operated when the anti-theft function is operated by remote control. The release function can be controlled.

In the present invention, the electromagnetic clamp or the solenoid valve is open to prevent unnecessary power consumption by preventing power from being applied while the anti-theft function is in operation. If the anti-theft function is released, if the power is supplied to the electronic clamp and solenoid valve, the finger of the electronic clamp opens and the parking brake is unlocked. Allows driving and driving

On the other hand, the input / output section of the control unit 6 includes a memory unit 20 storing an identification code and a password, an initialization button 22 for initializing the identification code stored in the memory unit 20, and an initialization button ( 22) each of the password button 24 for the operation that can be electrically operated normally, if the password input to the password button 24 matches the password stored in the memory unit 20 to initialize the identification code The identification code can be changed and memorized.

That is, when the identification code initialization button 22 installed in a secret place or a relatively difficult place of the vehicle is pressed, the identification code stored in the memory unit 20 is automatically deleted and another identification code can be stored. When the identification code is transmitted by pressing the button of the remote controller 2 in the above-described state, the first identification code (identification code) input through the receiving unit 4 and the control unit 6 is stored in the memory unit 20. The approval is used as the basic identification code, and any subsequent identification code entered is excluded from approval or storage.

In the case where a frame of one frame transmitted by the remote controller 2 is composed of a start signal, an identification code signal, a control signal, an end signal, and the like, when the control signal is input, the input and storage of the identification code are terminated. do.

On the other hand, since the identification code can be changed by the person who intentionally stolen the vehicle by pressing and approaching the initialization button 22, the encryption button 24 for operating the circuit in a state in which the initialization button 22 can be electrically operated is connected. Only if the passwords match, the identification code can be initialized.

The encryption button 24 makes it possible to assign 10 ³² or more codes using key metrics so that decryption or decryption is almost impossible and the initialization button 22 when the passwords previously stored in the memory unit 20 do not match. Even if it is pressed, the memory unit 20 is not initialized to ensure security.

If the password stored in the memory unit 20 is coerced or accidentally leaked, it is necessary to change the password. In this case, the password may be changed by connecting the memory unit 20 and the password changing computer through an interface.

The remote controller 2 having the transmitter 38 connects the identification code unit 28 constituted by the code chip IC to the input / output unit of the control unit 26 constituted by a central positioning unit (CPU) or the like. ^It is possible to set a unique identification code (ID) for each remote control (2) up to 32, and the start button 30 that can be remotely started to the input of the control unit 26 and the door lock and theft prevention function can be linked. Door lock button 32 and door lock release function and anti-theft release function interlocking door lock button 34 and emergency button 44 and emergency release button (10 ³ key matrix consisting of a combination of numbers and letters) Button: 36, and a high frequency (RF) transmitter 38 having an antenna is connected, and a memory unit 40 storing an identification code and an emergency release password is connected to an input / output unit of the control unit 26, and the control unit Table that emits light when various buttons 30, 32, 34, 36, 44 are pressed to another output of 26. The unit 42 can be connected to check the button pressed state, and the transmission and reception distance can be extended and secured to the receiver 4 and the transmitter 38 using the rod antenna. do.

Meanwhile, the receiving unit 4 installed in the vehicle receives and demodulates a signal input from the remote remote controller 2 and inputs it to the control unit 6, and the control unit 6 receives a code signal input from the receiving unit 4. Is compared with the code stored in the memory unit 20, and control commands inputted as rain, for example, start or door lock, door open, anti-theft, anti-theft release, emergency signal transmission, emergency signal release commands.

When the driver presses the emergency button 44 of the remote remote controller 2 when the driver feels a threat of personal injury, an emergency signal is transmitted through the transmitter 38 and a transmission antenna, and the transmitted emergency signal is received through the receiver 4. ㆍ Demodulated and then input to the control unit 6, the control unit 6 is an emergency signal via a black box (see Patent Application No. 98-2864, "Vehicle Black Box", filed Feb. 26, 1998) (Emergency signal), the vehicle number and the characteristics of the vehicle are transmitted wirelessly, and the signal is received at a checkpoint in the vicinity where a stolen signal receiver or an emergency signal receiver is installed, or a patrol car and a patrol vehicle carrying these receivers, thereby eliminating emergency situations. Crime can be prevented.

To install three or open more of the plurality as an emergency off button (32) 3 of the remote remote control (2) sets the emergency release code greater than or equal to 10 ³ in the above, and so they can be stored in the memory unit 40, When the driver presses the emergency button 44 and the emergency signal is sent and the emergency release code is matched, the control unit 26 stops the transmission of the emergency signal, and if the emergency release code does not match the control unit 26. ) Sends out an emergency signal continuously.

On the other hand, the brake device installed in the vehicle is an important device used to decelerate or stop the vehicle while driving and at the same time maintain the parking state. The brake device converts the kinetic energy of the vehicle into thermal energy by using friction force and brakes. Equalize 12 is mainly installed on the rear axle.
