Description

Preventive use of mobile communication during driving

The present invention relates to a mobile communication call prevention device while driving a vehicle. More particularly, a vehicle equipped with a jammer generating device capable of preventing a mobile communication call may travel at a predetermined speed or more, or a mobile communication terminal may be mounted on a hand free. If a predetermined signal is output from the handfree within a short time, the jammer generator for preventing the reception of the mobile communication terminal is activated. Thus, the driver may operate the mobile communication terminal while the vehicle is running or the mobile communication terminal is not mounted on the handfree. It is invented to prevent the safety accident that can occur by performing the communication used in advance.

Since the call using the mobile communication terminal of the driver during the movement of the vehicle acts as a factor that hinders safe driving, the act is currently prohibited.

However, most automobiles are currently capable of making calls using mobile communication terminals while the vehicle is in operation, regardless of these regulations.

On the other hand, Korean Patent Publication No. 295362 (Mobile communication terminal jammer generator by infrared remote control: April 27, 2001) has been proposed as a device for preventing calls using indiscriminate mobile communication terminals in public places. .

However, such a device is constructed so that all mobile communication terminals cannot be used because the device is always operated regardless of other surrounding conditions in the area where the device is mounted.

The present invention has been made to solve the above-mentioned conventional problems, and equipped with a conventional jammer generator in a vehicle, the jammer generator itself is a mobile communication terminal in the state in which the vehicle is running or hand-free Is operated in the non-equipped state so that a call can be made while the vehicle is stopped or in a vehicle using the hand free, and the speed or the mobile communication terminal is not mounted on the hand free so as to impede safe driving. The purpose of the present invention is to provide a mobile communication call prevention device while driving a vehicle which can prevent the occurrence of a safety accident due to the use of a mobile communication terminal.

An object of the present invention described above includes: a driving state detection unit for detecting whether a shift lever is in a traveling range; A traveling speed detection unit for detecting whether the traveling speed of the vehicle is equal to or greater than a predetermined speed; A handfree / terminal binding detection unit for detecting whether a mobile communication terminal is connected to a handfree mounted in a vehicle; First and second amplifiers for amplifying output signals of the driving state and the speed detector at predetermined levels, respectively; An inverter for inverting the output signal of the hand free / terminal binding detection unit; A first ora gate which logically adds the output signals of the two amplifiers and outputs a high signal when a high signal is input to any one of them; A second OR gate which logically adds the output signals of the first OR gate and the inverter and generates a high signal when a high signal is input to any one of them; This can be achieved by configuring a power supply control unit for controlling the power supply voltage supplied to the jammer generator for the mobile communication terminal in response to the output signal of the second OR gate.

Therefore, when the vehicle is driving or when the mobile communication terminal is not mounted on the handfree itself, the jammer generator is always driven. Therefore, the mobile communication terminal cannot be used in the vehicle under the above conditions. Therefore, it is possible to prevent the occurrence of safety accidents in advance, thereby ensuring the stability of the driving of the car.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a block diagram of an apparatus of the present invention, and FIG. 2 shows a flowchart for explaining an operation state of the apparatus of the present invention.

According to this, the driving state detection unit 1 for detecting whether the shift lever is in the driving range;

A traveling speed detector (2) for detecting whether the traveling speed of the vehicle is equal to or greater than a predetermined speed (0 km / h);

A hand free / terminal connection detection unit 3 for detecting whether a mobile communication terminal is connected to a hand free mounted in a vehicle;

First and second amplifiers (4) (5) for amplifying output signals of the driving state and speed detector (1) (2) at predetermined levels, respectively;

An inverter (6) for inverting an output signal of the hand-free reception state detector (3) which generates a low signal when the mobile communication terminal is not mounted;

A first ora gate (7) which logically adds the output signals of the two amplifiers (4) (5) and outputs a high signal when a high signal is input to any one of them;

A second OR gate 8 which logically adds the output signals of the first OR gate 7 and the inverter 6 and generates a high signal when a high signal is input to any one of them;

And a power control unit 9 for controlling a power supply voltage supplied to the jammer generator 10 for the mobile communication terminal in response to the output signal of the second OR gate 8.

In this case, an oar gate having three inputs may be used instead of the first and second oar gates 7 and 8 having two input terminals.

Referring to the operation and effect of the device of the present invention configured as described above are as follows.

First, as a result of detecting the position of the shift lever by the driving state detection unit 1, when it is in the driving range, or when the driving speed detection unit 2 detects the driving speed of the vehicle, the driving speed detection unit 2 detects the driving speed more than a predetermined speed (0 km / h). High "signal is output.

At this time, the output state of the driving state and the speed detection unit (1) (2) has a low level for the logic element to recognize, so that the first and second amplification unit (4) (5) amplified to a predetermined level, respectively It is then input to the first OR gate 6.

On the other hand, the hand free / terminal connection detection unit 3 detects whether or not the mobile communication terminal is connected to the hand free mounted in the vehicle, and outputs a "high" signal if the mobile communication terminal is mounted and the mobile communication terminal is not installed. If not, it outputs a "low" signal.

Therefore, when the driver or the like does not connect the mobile communication terminal to the hand-free mounted in the vehicle, the output signal of the hand-free / terminal connection detection unit 3 is in the "low" state. At the output terminal, a "high" signal is output.

Therefore, the first ora gate 7 maintains a "high" state whenever the shift lever of the vehicle is in the driving range, or the driving speed of the vehicle is more than a predetermined speed, and the second ora gate 8 is described above. The "high" signal is output even when the mobile terminal is not mounted in the hand-free including all the conditions.

Accordingly, the power control unit 9 controlled by the output signal of the second ora gate 8 may move when the speed range of the vehicle is in the driving range, when driving at a predetermined speed or more, or in the hand free itself. It is driven unconditionally without the communication terminal and supplies power voltage to the jammer generator.

That is, even if any one of the above conditions is satisfied, the well-known jammer generator 10 installed in the inside of the car is operated. Therefore, a direct call through the mobile communication terminal without using the hands-free in the driving vehicle is performed. Since the safety accident itself may be prevented in advance because it is possible to ensure the stability of the driving of the car.

As described above, according to the present invention, when a call using a mobile communication terminal is to be made in a vehicle in which a jammer generator is installed, the vehicle is in a running state or a state in which the mobile communication terminal is not installed in the hand free. Can not make a call (i.e., it is impossible to make a call because the jammer is activated under the above conditions). In the absence of speed or interference with the mobile terminal, the use of the mobile terminal is eliminated, which prevents the occurrence of safety accidents and secures the stability of the vehicle. You can do it.
