[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 It is a technical field of the automobile manufacturing industry and the vehicle accessories manufacturing industry.

[0002]

[Prior art]

 As measures to prevent automobile theft, lock the vehicle door, detect contact with the vehicle or open the door, emit an alarm sound, and link a wireless device etc. to the operation of the switch provided on the door when the locked vehicle door is opened The purpose of this is to notify the receiving device by transmitting a signal using a radio wave transmitting device that operates when the vehicle door is opened and closed. Also, a sensor is installed near the entrance of the garage to detect illegal intruders and prevent theft accidents.

[0003]

[Problems to be solved by the invention]

 The purpose is to prevent theft of the vehicle due to the duplicate key of an automobile or the direct connection of an electric circuit. Prevent theft by making it impossible.

[0004]

[Means for Solving the Problems]

 The engine operates but cannot run by lowering or cutting off the power supply voltage of the IC of the electronic control circuit of the transmission system of the mission control electronic circuit, which is remotely controlled by the chain lever of the automobile. A power supply voltage automatic control circuit that drops or shuts off the voltage of the IC of the electronic control circuit of the transmission system by using any of radio waves, magnetic pole waves, and wired control as means to prevent unauthorized use. A device consisting of a numerical code recognition circuit linked to the circuit and a voltage control switch circuit linked to the circuit is installed in the vehicle. This device operates automatically after a certain number of seconds after the engine stops. To control a part of the voltage of the IC of the electronic control circuit of the traveling system of the transmission control The voltage of the IC drops and shuts off. Then, even if the engine is started by the engine key and the shift lever shift is shifted to the running position, the IC circuit that electronically controls the shift control device does not operate because the voltage of the IC circuit drops or shuts down. In order to return the voltage of a part of the IC of the transmission control circuit of the remote transmission control by the interrupted change lever to normal, the numerical value is obtained by the radio wave, the magnetic pole wave, the wire control, etc. used for the previous interruption. By transmitting a preset numerical code to the code recognition circuit, the switch circuit linked to the automatic power supply voltage control circuit is activated and cut off. However, in this case, the position of the shift lever that remotely controls the transmission control signal is always the shift display P That enables receiving transmissions numerical code only when it is in position.

[0005]

[Action]

 The power supply voltage of the IC of the electronic control circuit of the transmission system, which is remotely controlled by the change lever of the automobile, is cut off or the voltage is reduced to stop the electronic control operation of the transmission system by the transmission control signal. The vehicle cannot be stolen and cannot be used illegally.Even if it is directly connected, such as with a duplicate key or electric wiring, the electrical signal of the transmission control operation by the engine start change lever is cut off and the vehicle cannot run. However, since the engine starts, instruments and lights operate normally, they do not touch traffic rules and only run. This prevents theft.

[0006]

[Embodiment of the invention]

 If a certain set number of seconds has elapsed after the engine stopped, the voltage of the electronic circuit of the transmission system of the vehicle's transmission control is cut off or lowered.Transmission control by change lever operation becomes impossible and the vehicle can run even if the engine is started. In this case, in order to connect the transmission control signal again, if the numerical code is transmitted to the numerical code recognition circuit, the transmission control signal returns to normal by the operation of the power supply voltage automatic control circuit and the vehicle can run.

[0007]

【Example】

Control unit for system control electronic circuit Figure 1-5 shows a change lever position diagram for operating the transmission control unit, which controls the voltage of part of the IC, such as dropping or cutting off the voltage. The mission control signal is remotely operated by the chain lever, and the operation signal is transmitted to the transmission control circuit via the signal wire harness (FIG. 1-3). In this case, the numerical code is recognized at the change lever position described below. Power supply voltage control circuit by operation of circuit The switch of Fig. 1-9 does not operate, its lever The positions are FIGS. 1-15, 1-17, 1-18, 1-19, and the limiting method or lever positions, then the power supply voltage automatic control circuit diagram 1-9, to activate the numerical sign recognition. Using the operating contacts of the switch circuit of the transmitting and receiving device, and turning the numerical code into a personal identification number to operate it will be a measure to prevent unauthorized use and theft of vehicles.Radio wave, as a method of storing, transmitting and collating the numerical code, In any case, such as a magnetic pole wave, a wired control, etc., it is necessary to store and set in advance. The numerical code that is set and stored is reproduced, and the signal to be transmitted is transmitted by the transmitting device shown in FIG. 1-11. For example, in the case of the magnetic pole transmission system, there are nine magnetic pole number maps 2-22 provided with a box perpendicular to the plane of the magnetic pole memory card Figure 2-21. 2- 3 and 9 are respectively enclosed. A magnetic pole generator is used to store and set magnetic poles in a cylindrical iron piece enclosed in the magnetic pole storage card. FIG. -26, so input an arbitrary address. The magnetic pole element shown in Fig. 3-24, the iron piece enclosed in the magnetic pole memory card Fig. 2-21, and the magnetic pole in Fig. 2-23 are maintained at each address. When the magnetic pole address matches the magnetic pole recognition address of the numerical code recognition circuits on both sides of the vehicle, the power supply voltage automatic control circuit is activated. A numerical code as a personal identification number is used, and the signal of the numerical code is collated by the numerical code recognition circuit diagram 1-10. After the stop, the contacts of the switches that are in the open state are closed, and the power supply voltage that has been cut off or dropped returns to the normal value, and normal vehicle running is possible.

[0008]

[Effect of the invention]

 There are various methods to prevent automobile theft, such as a vehicle door key, a steering wheel lock, and a warning sound emitting device using a contact sensor. In any case, the engine is running. In this invention, the engine operates but the running is disabled. Therefore, it is a device that disables the vehicle by lowering or cutting off the power supply voltage of the IC in the transmission control signal system. Therefore, the vehicle cannot be moved by a method such as using a duplicate key or connecting an electric circuit. In order to restore the power supply voltage of the transmission control signal that has been shut off, a password consisting of a numerical code that has been set and stored in advance is transmitted, and the numerical code is compared and matched. Since it is a device that can run, it is not easy for a third party to drive a vehicle for the purpose of theft.
