Description

DETAILED DESCRIPTION OF THE INVENTION In general, an automobile engine starting circuit connects a starter cell motor and an ignition circuit to a battery via a main switch and a starter switch, and closes the main switch and starter switch using the engine key to start the engine. Since the engine is started, drivers tend to forget to bring their driver's license with them, and if the engine key is stolen, there is a risk of car theft.

In order to prevent this, a case for storing the driver's license is prepared, a translucent window for signal setting is provided in the storage case, a switching element is further connected to the engine starting circuit, and the storage case is connected to the signal setting section. An engine start control device has been proposed that is inserted into a vehicle and optically detects the presence or absence of a driver's license through its transparent window, and operates the opening/closing element based on the detection signal to make the engine start circuit conductive or nonconductive. Ta. The present invention further improves these, so that if the engine key is inserted without a driver's license, it not only makes it impossible to start the engine, but also sounds a horn.

Embodiments of the present invention will be described below with reference to the drawings. 1st
In the figure, an engine starting circuit A and a crank circuit B are connected in parallel to a power source 1. First, the engine starting circuit A connects a main switch 2 and a starter switch 3 as key switches in series.
A magnetic switch 5 is connected to the magnetic switch 5 via a switching element 4 such as a relay.
In addition to connecting the starter cell motor 6, the ignition coil 7 and point 8 are connected to the main switch 2.
An ignition circuit containing a driver's license 9 is connected thereto, and a discrimination signal is sent to the opening/closing element 4 of the starting circuit A from a case 10 containing a driver's license 9.

The current driver's license 9 is a rectangular card with rounded sides 11 at the four corners as shown in the second diagram, and its entire surface is covered with a transparent synthetic resin film with good light reflectivity. be.

The storage case 10 is, for example, an opaque flat sheath-like case having an insertion groove 12 with an opening at one end into which the driver's license 9 can be inserted. A rounded corner 14 having rounded sides 13 corresponding to the two corners of the driver's license 9 is formed, and an arc corresponding to the rounded side 13 is formed as a part of the window frame at a position corresponding to the rounded corner 14 of this case. In addition, a fan-shaped light-transmitting window 15 for setting signals that can transmit light to the front and back of the case is provided, and as shown in the second figure, a narrow window 15 is formed on the other side of the case surface using paint with good light reflectivity such as silver. An optical code number 18 representing the arrangement of the width portion 16 and the wide width portion 17 is printed. A driver's license signal setting part 19 is installed at a suitable place on the dashboard inside the car, and a case holder 2 into which the storage case 10 is inserted is installed in the setting part 19.
0, and a light emitting element 21 such as a light emitting diode that projects light diagonally onto the transparent window 15 of the storage case 10, and a light emitting element 21 such as a light emitting diode that projects light obliquely onto the transparent window 15 of the storage case 10, and when the light projected from the light emitting element is reflected on the driver's license 9 surface, the reflected light is A photoelectric conversion element 22 such as a phototransistor that receives light and outputs an electric signal with a license, a light emitting element 23 that projects light onto the optical code number 18, and the light projected from the light emitting element is connected to each narrow portion. Each of the photoelectric conversion elements 24 is equipped with a photoelectric conversion element 24 that receives each reflected light beam when it is reflected by the surfaces of the narrow width part 16 and the wide width part 17, reads the code number corresponding to the permutation of the narrow width part and the wide width part, and outputs an electric signal. 24 is connected to a determination circuit 25 that receives the code number reading signal and determines whether or not the code number matches the code number specified in advance by the driver's license, and outputs an electric signal indicating a match. and sends the electrical signal indicating the presence of the driver's license and the code number matching signal to the switching element 4,
The switching element 4 is configured to close when it receives both signals, and to remain open when it does not.

Next, the crankshaft circuit B connects the opening/closing contact 27 of the crankshaft relay 26 and the crankshaft 29 to the power source 1 in series, connects its coil 28 to the power source 1, and connects the handle crankshaft switch 30, a transistor, etc. to the coil 28. A control circuit 32 for opening and closing the switching elements 31 is connected to the switching elements 31 in parallel.

The control circuit 32 is connected to the starter switch 3 and the photoelectric conversion element 22, and when it receives an electric signal indicating that a driver's license is present from the photoelectric conversion element 22, it controls the voltage applied to the control circuit from the power source 1. All of them are grounded, thereby leaving the switching element 31 open without applying any output, and when no electrical signal is received, the voltage applied to the control circuit is applied to the switching element 31 to close the switching element 31. It is something. The operation of this device will be explained next.

When the case 10 into which the regular driver's license 9 has been inserted is inserted into the case holder 20 of the signal setting section 19, a signal indicating that the driver's license is present from the photoelectric conversion element 22 and a signal that the code number matches from the discrimination circuit 25 are opened and closed, respectively. The signal is sent to the switching element 4, thereby closing the switching element 4. In this state, when the engine key is inserted and the main switch 2 and starter switch 3 are closed, voltage is applied to the starter motor 6 and the engine starts. On the other hand, a voltage is applied to the control circuit 32;
Since a signal indicating that a driver's license is present is sent to the control circuit 32, all the voltage is passed to the ground to keep the switching element 31 open, thereby keeping the klaxon circuit B open and making it possible to sound the klaxon 29. do not have. Next, if the person who stole the engine key inserts only the key without a driver's license, the engine will not start because the opening/closing element 4 remains open even if the main switch 2 and starter switch 3 are closed.

On the other hand, since the signal indicating that a driver's license is present is not sent to the control circuit 22, the voltage applied to the control circuit 32 becomes an output and closes the switching element 31, thereby closing the crank circuit B and turning the crank 29 on. sounds to warn of an accident. If you forget your driver's license 9 at home and insert only the case 10 into the signal setting section 19, or if someone else steals the case 10 and inserts it in the same way, the driver's license presence signal will be sent to the switching element 4 and control circuit 32. Since the signal is not sent, the engine does not start and the horn 29 sounds as described above.

If someone else steals the case 10 and the engine key, inserts a rectangular cardboard such as a business card into the insertion groove 12 of the case 10 instead of a driver's license, and inserts it into the signal setting section 19,
The fan-shaped light-transmitting window 15 cannot be blocked by the right-angled corner of the rectangular cardboard, and a wide open area is left, so that the light from the light emitting element 21 is transmitted through the open area and is received by the photoelectric conversion element 22. Therefore, a signal indicating that a driver's license is present is not sent to the switching element 4 and the control circuit 32.

In another embodiment shown in FIG. 3, the switching element 4a in the starting circuit A is connected to the ignition coil 7 of the ignition circuit.
In this example, the other configuration is substantially the same as that in FIG. 1.

In any of the above examples, the crank circuit B has a crank 29b connected to a power source 1b as shown in FIG. It may be substantially the same as the above example.

According to the motor vehicle engine start control and alarm device of the present invention, when the key switch is closed with the engine key without a driver's license, the engine start is disabled and the horn is automatically sounded at the same time. If the driver's license is the result of someone else's actions, it will warn that the driver's license has been left behind, and if the driver's license is the result of someone who has stolen the engine key, it will warn of the occurrence of a theft accident, which is extremely effective.
