Description

Driving control device when the parking brake of the car

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving control apparatus when a parking brake of a vehicle is operated. In particular, when a driver accidentally starts the vehicle while the parking brake of the vehicle is activated, the driving of the vehicle is stopped by cutting off fuel supplied to the engine of the vehicle. And a parking brake warning light to inform the driver that the parking brake device is in operation, thereby preventing the vehicle's parking brake device from being damaged by a driver's mistake. .

In general, a car is equipped with a parking brake device to prevent the car from moving due to the inclination of the road surface or other external force applied to the car when the car is parked.

The parking brake device of such a conventional vehicle has a shaft when the parking brake switch 1, the parking brake handle 2, the first rod 3, and the first rod 3 move as shown in FIG. A moving latch 4 interlocking to the center, a toothed portion 9 to which the ends of the movable latch 4 are coupled, a fixing plate 5 having a toothed portion 9 formed on an outer circumferential surface thereof, and one end of the parking brake handle ( 2) is formed and the other end is composed of a second rod (6) fixed to the shaft and movable about the axis, and a cable (7) connected to the other end connected to the shaft of the second rod (6).

The operation of the parking brake device of a conventional vehicle as described above is as follows.

First, when the driver who has completed driving of the vehicle presses the parking brake switch 1 by hand while the vehicle is stopped, the first rod 3 is moved in the direction in which the parking brake switch 1 is pressed and thus moved. The latch 4 is moved about the shaft so that the end of the parking brake switch 1 and the teeth 9 are disengaged.

Then, when the driver pushes the parking brake knob 2 upward while pressing the parking brake switch 1, the second rod 6 coupled to the shaft rotates about the shaft so that the cable 7 can be pulled. do.

Therefore, the parking brake is activated.

Afterwards, when the driver turns off the parking brake switch 1, the first rod 3 moves upwards, and thus the movement latch 4 moves about an axis, so that one end of the movement latch 4 moves to the toothed portion 9. ) Is engaged.

One end of the moving latch 4 is engaged with the toothed portion 9 so that the cable 7 is maintained in the pulled state, and the parking brake of the vehicle is applied. As described above, in the conventional parking brake apparatus of a vehicle, the parking of the vehicle is performed by the driver pulling the parking brake lever by hand when the vehicle is parked. When the position of the tooth where the shift latch is engaged is determined and the driver parks the car on a flat surface, the driver does not pull the parking brake lever to the end, so that the tension generated by the cable becomes small and the driver accidentally Even when the vehicle is started while the parking brake is in operation, the vehicle is driven while the parking brake is in operation, thereby causing a problem that the driver breaks the parking brake device of the vehicle by mistake.

The present invention is to solve the problem of the conventional vehicle parking brake apparatus as described above, when the parking brake of the vehicle is applied by fixing the throttle valve in the position of the vehicle stop state, the parking brake of the vehicle is completely released. Even if the driver accidentally presses the accelerator pedal to drive the vehicle, the accelerator pedal is not operated due to the fixing of the throttle valve, thereby preventing the vehicle from driving. It is an object of the present invention to provide a driving control device at the time of parking brake action of a vehicle which can prevent the brake device from being damaged.

In order to achieve the object as described above, the driving control apparatus when the parking brake acts on the vehicle of the present invention is operated by driving the parking brake position detection switch, the electronic control unit to which a signal is applied from the parking brake position detection switch, and the engine. The air tank is applied, a control signal is applied from the electronic control unit and the solenoid valve for opening and closing the air pressure applied from the air tank, the air pressure is applied through the solenoid valve and the actuator is protruding the first rod, One end is connected to the first rod and the center part is fixed, a second rod connected to the other end of the lever, a master cylinder connected to the second rod, the hydraulic pressure generated in the master cylinder is applied Release cylinder in which the third rod protrudes, wherein the third rod is one side Turn buckle which is connected to, a load 4 that is connected to the other end of the turn buckle, it characterized in that it comprises a throttle valve which is above the fourth load saptal the stopper hole being formed.

With reference to the accompanying drawings an embodiment of the driving control device when the parking brake action of the vehicle of the present invention having the configuration as described above in detail as follows.

First, the driving control apparatus for the parking brake of the vehicle according to the embodiment of the present invention has a signal at the parking brake position detecting switch 11 and the parking brake position detecting switch 11 as shown in FIG. 2. The electronic control unit 13 to be applied, the air tank 14 driven as the engine is driven, the control signal is applied from the electronic control unit 13 and the air pressure applied to open and close the air tank 14 One end of the solenoid valve 15, the actuator 16 to which the air pressure is applied through the solenoid valve 15 and the first rod 17 protrudes, and the first rod 17 are connected, A fixed lever 18, a second rod 19 connected to the other end of the lever 18, a master cylinder 20 connected to the second rod 19, and the master cylinder 20 Hydraulic pressure from the 3 release cylinder 21 from which the rod 22 protrudes, a turn buckle 23 to which the third rod 22 is connected at one end, and a fourth to be connected to the other end of the turn buckle 23. The rod 24 and the throttle valve 25 in which the stopper hole 26 into which the said 4th rod 24 is inserted are formed are formed.

Referring to the operation of the driving control device when the parking brake action of the vehicle according to an embodiment of the present invention having the configuration as described above are as follows.

First, when a driver starts a car, air pressure is generated in the air tank 14 by driving of an engine (not shown).

At this time, the parking brake position detection switch 11, in which the driver stops the vehicle and pulls the parking brake lever, detects this and applies a signal to the electronic control unit 13. Therefore, when the signal is applied from the parking brake position detection switch 11, the electronic control unit 13 applies the control signal to the solenoid valve 15 to open the solenoid valve 15 above.

Therefore, when the solenoid valve 15 is opened, the air pressure acts on the actuator 16 in the air tank 14 to pull the first rod 17 protruding from the actuator 16 and the above-mentioned first agent. 1 The lever 18 moves in conjunction with the pulling of the rod 17.

As the second rod 19 connected to one end of the lever 18 is pushed by the movement of the lever 18, hydraulic pressure is generated in the master cylinder 20 and is generated in the master cylinder 20. The hydraulic pressure is applied to the release cylinder 21.

Accordingly, when hydraulic pressure is applied to the release cylinder 21 in the master cylinder 20, the third rod 22 protruding from the release cylinder 21 by the hydraulic pressure is connected to the turn buckle 23. The fourth rod 24 is coupled to the stopper hole 26 of the throttle valve 25 by pushing the four rods 24.

As a result, the throttle valve of the vehicle is fixed when the parking brake is operated.

When the parking brake of the vehicle is operated by the driving control device when the parking brake of the vehicle of the present invention is operated as described above, the throttle valve is fixed to a position in the vehicle stop state so that the parking brake of the vehicle is not completely released. Even if the driver accidentally presses the accelerator pedal to drive the vehicle, the accelerator pedal is not operated due to the fixing of the throttle valve, thereby preventing the driving of the vehicle. The effect which can prevent that becomes is exhibited.
