The control unit 50 receives signals of the speed sensing means 20, the acceleration sensing means 5 and the distance measuring means 30 and controls the operation of the fixing means 10 and the auxiliary fixing means 40 .

More specifically, when the driver depresses the brake pedal 1 to stop the vehicle, the control unit 50 receives the signal of the speed sensing means 20 and detects that the vehicle is completely stopped.

Then, when the vehicle is kept stopped for a predetermined time, the control unit 50 turns on the fixing means 10 so that the brake pedal 1 is fixed. It is also possible to operate the fixing means 10 when the brake pedal 1 is depressed for a predetermined time or longer in the vehicle stop state.

Therefore, even if the driver releases his / her foot from the brake pedal 1, the brake pedal 1 is not returned to its original position, and thus the vehicle remains stationary.

The control unit 50 receives the signal of the distance measuring means 30 and turns on the other vehicle within a predetermined distance (for example, 1 m) in front of the vehicle, The auxiliary fixing means 40 is turned on to fix the accelerator pedal 2 so as not to move.

Then, when there is no other vehicle or obstacle within a predetermined distance in front of the vehicle, the control unit 50 turns off the auxiliary fixing means 40 so that the accelerator pedal 2 can move.

When the driver depresses the accelerator pedal 2, the control unit 50 receives and confirms the signal of the acceleration sensing means 5 and turns off the fixing means 10 to turn the brake pedal 1 Is returned to its original position, so that the vehicle can be advanced.

The braking control device for a vehicle thus structured comprises a fixing means 10 connected to a brake pedal 1 provided on the driver's seat of the vehicle for restricting the movement of the brake pedal 1 and a speed sensing means And a control unit 50 for sensing the signal from the speed sensing means 20 and controlling the operation of the fixing means 10. When the vehicle is stopped, By fixing the pedal 1 so as not to move, the vehicle is maintained in a stopped state.

Therefore, unlike a conventional automatic brake device which operates the braking device of the vehicle when the vehicle is stopped, not only the structure is very simple, but also the braking pedal 1 is fixed so as not to move so that the drafting device is inadvertently operated There is an advantage that an accident can be prevented from occurring.

The vehicle is provided with a distance measuring means 30 for measuring the distance to an obstacle ahead of the vehicle and an accelerator pedal 2 provided on the driver's seat of the vehicle is provided with auxiliary securing means The control unit 50 receives the signal of the distance measurement means 30 and operates the auxiliary fixing means 40 to detect the presence of an obstacle in front of the vehicle, There is an advantage that an accident can be prevented from occurring due to the driver stepping on the accelerator pedal 2 by mistake.

The fixing means 10 includes a drum 11 coupled to the hinge shaft 1a of the brake pedal 1, a brake band 12 provided at the periphery of the drum 11, And a solenoid unit 13 connected to the band 12 and pulling the brake band 12 when power is applied to the brake band 12 so that the brake band 12 is brought into close contact with the circumferential surface of the drum 11. [

Therefore, the brake pedal 1 has a very simple structure, high operational reliability, and a very high speed of fixing or releasing the brake pedal 1.

The fixing means 10 includes a drum 11 coupled to the hinge shaft 1a of the brake pedal 1 and a brake band 12 provided at the periphery of the drum 11, And a solenoid device 13 which is connected to the brake band 12 and pulls the brake band 12 when power is applied so that the brake band 12 is brought into close contact with the circumferential surface of the drum 11. However, The structure of the fixing means 10 can be variously changed.

In the present embodiment, when the driver depresses the accelerator pedal 2 in a state where the fixing means 10 is operated and the brake pedal 1 is fixed, the control unit 50 controls the acceleration sensing means 5 , The fixing means 10 is turned off. However, the method of turning the fixing means 10 off is not limited to this, and various methods including using a separate operation switch can be used.

4 and 5 illustrate another embodiment according to the present invention in which a one way bearing 60 is provided between the hinge shaft 1a of the brake pedal 1 and the drum 11, The brake pedal 1 is further strongly depressed by the driver in a state where the drum 11 is fixed by the fixing means 10 so that the braking force can be generated more strongly.

The hinge shaft 1a is rotated in a direction in which the brake pedal 1 is lowered in a state where the drum 11 is fixed by the brake band 12 so that the drum 11 is not rotated, Lt; / RTI >

The one-way bearing 60 includes an inner ring 61 coupled to the hinge shaft 1a and an inner ring 61 rotatably coupled to the outer side of the inner ring 61 and fixed to the drum 11, (62), and a roller pin (63) provided between the inner ring (61) and the outer ring (62).

At this time, an inclined groove 61a into which the roller pin 63 is inserted is formed on the outer circumferential surface of the inner ring 61.

The inclined grooves 61a are formed so as to be deeper toward the counterclockwise direction.

Therefore, when the drum 11 is fixed by the fixing means 10 in a state in which the driver depresses the brake pedal 1, as shown in Fig. 4, the roller pin 63 is inserted into the inclined grooves 61a The inner ring 61 and the outer ring 62 are fixed to each other by the roller pin 63 so that the hinge shaft 1a and the brake pedal 1 are located on the upper side That is, not rotated in the counterclockwise direction.

5, when the driver depresses the brake pedal 1 again in the state where the drum 11 is fixed by the fixing means 10, the inner ring 61 rotates clockwise The roller pin 63 is positioned in a deep portion of the inclined groove 61a in the counterclockwise direction so that the fixing of the inner ring 61 and the outer ring 62 is released, The shaft 1a and the brake pedal 1 can be rotated downward, that is, clockwise.

Since such a one-way bearing 60 is generally used, no further detailed description of the action caused by the one-way bearing 60 will be provided.

When the driver depresses the brake pedal 1 in a state where the drum 11, the hinge shaft 1a and the brake pedal 1 are fixed by the fixing means 10, the brake pedal 1, (1) is rotated downward, which makes it possible to operate the vehicle braking apparatus more strongly.

That is, in the case of the above-described first embodiment, since the hinge shaft 1a and the drum 11 are integrally fixed, when the driver steps on the brake pedal 1, the fixing means 10 is operated , The brake pedal 1 is fixed so as not to move.

Therefore, even if the driver depresses the brake pedal 1 more deeply once again after the fixing means 10 is operated, it is not possible to deeply depress the brake pedal 1 again Do.

However, in the case of this embodiment, the one-way bearing 60 provided between the hinge shaft 1a of the brake pedal 1 and the drum 11 is provided so that even when the fixing means 10 is operated When the brake pedal 1 is depressed, the brake pedal 1 is pushed down more deeply, so that the brake pedal 1 is depressed more strongly, so that the brake pedal 1 is strongly depressed again and the vehicle is strongly braked .

6 and 7 show a third embodiment according to the present invention. The brake pedal 1 is provided with a turning angle measuring means 6 for measuring the amount by which the user steps on the brake pedal 1.

The rotation angle measuring means 6 uses an angle measuring sensor which is coupled to the hinge shaft 1a of the brake pedal 1 and measures a rotation angle of the brake pedal 1. When the driver rotates the brake pedal 1 ) Is measured.

The control unit 50 receives the signals of the speed sensing means 20 and the rotation angle measuring means 6 so that the brake pedal 1 is operated until the preset time elapses after the vehicle is completely stopped And is configured to actuate the fixing means (10) when it is turned over a certain angle.

In the vehicle braking control apparatus constructed as described above, the locking means 10 is operated only when the driver strongly depresses the brake pedal 1 and the brake pedal 1 is rotated at a predetermined angle or more.

Therefore, there is an advantage that the fixing means 10 can be prevented from being unnecessarily operated even when the driver tries to stop the vehicle for a while.

In the case of the above embodiment, the control unit 50 receives the signal of the distance measuring means 30 and, when there is another vehicle or obstacle within a predetermined distance in front of the vehicle, the auxiliary fixing means 40 the acceleration pedal 2 is fixed so as not to move so that the accelerator pedal 2 can be moved by turning off the auxiliary fixing means 40 when the vehicle or obstacle in the front is removed. A separate alarm function is added to the driver 50 to output an alarm when there is another vehicle or an obstacle within a predetermined distance in front of the vehicle or when the auxiliary fixing means 40 is turned off, Or < / RTI >
