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.

As shown in FIG. 1, the parking brake device of the conventional vehicle is centered on an axis when the parking brake switch 1, the parking brake handle 2, the first rod 3, and the first rod 3 are moved. Movement latch 4 interlocked with each other, tooth portion 9 to which end of movement latch 4 is coupled, fixing plate 5 having tooth portion 9 formed on the outer circumferential surface thereof, and parking brake handle 2 at one end thereof. ) And the other end consists 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.

Accordingly, 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, thereby acting as a parking brake of the vehicle.

However, the parking brake device of a conventional vehicle as described above, when the vehicle is parked, the driver pulls the parking brake lever by hand, so that the parking of the vehicle is performed. At this time, the driver pulls the parking brake lever. Accordingly, the position of the tooth where the shift latch is engaged is determined, and when the driver parks the car on a flat surface, since the driver does not pull the parking brake lever all the way, the tension generated by the cable becomes small, which causes the driver to make a mistake. Even when the vehicle is started while the parking brake is actuated, the vehicle is operated while the parking brake is actuated, thereby causing a problem that the driver breaks the parking brake device of the vehicle by mistake.

The present invention is to solve the problems of the conventional parking brake device of the vehicle as described above, when the parking brake of the vehicle is actuated 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.

1 is a view showing the configuration of a parking brake apparatus of a conventional vehicle.

2 is a view showing the configuration of a driving control device when the parking brake action of the vehicle of the present invention.

In order to achieve the above object, the driving control apparatus for a parking brake of the present invention includes a parking brake position detecting switch, an electronic control unit to which a signal is applied from the parking brake position detecting switch, and the electronic control unit. A relay to which a control signal is applied to a coil, a battery connected to one end of the switch of the relay to supply power, a solenoid connected to the other end of the switch of the relay, a first rod protruding from the solenoid, one side The lever is connected to the first rod and the center portion is fixed, the second rod connected to the other end of the lever, the master cylinder connected to the second rod, the hydraulic pressure generated in the master cylinder Release cylinder applied, third rod protruding from said release cylinder, phase Of claim is characterized in that it comprises a throttle valve 3 which is loaded saptal the stopper hole being formed.

When described in detail with reference to the accompanying drawings an embodiment of the driving control device during the parking brake action of the vehicle of the present invention having the configuration as described above 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. An electronic control unit 13 to be applied, a relay 14 to which a control signal is applied to a coil in the electronic control unit 13, and a battery 16 connected to one end of a switch of the relay 14 to supply power. ), A solenoid 15 connected to the other end of the switch of the relay 14, a first rod 17 protruding from the solenoid 15, one end of the relay rod 14 to the first rod 17 A lever 18 having a central portion fixed thereto, 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 Hydraulic pressure generated from the master cylinder 20 is applied And a throttle valve 25 in which a lease cylinder 21, a third rod 22 protruding from the release cylinder 21, and a stopper hole 26 through which the third rod 22 is inserted are formed. do.

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 the driver stops the vehicle in order for the driver of the vehicle to park the vehicle and then pulls the parking brake lever of the vehicle, the parking brake position detection switch 11 detects this and applies a signal to the electronic control unit 13. Therefore, the electronic control unit 13 applies a control signal to the coil of the relay 14 when a signal is applied from the parking brake position detection switch 11.

Therefore, when a signal is applied to the coil of the relay 14, the switch of the relay 14 is turned on by the electric field generated by the coil so that the power of the battery 16 is applied to the solenoid 15.

Therefore, the first rod 17 protruding from the solenoid 15 is pulled, and thus the lever 18 moves in conjunction with each other.

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.

Therefore, 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 is pushed by the hydraulic pressure, and thus the third rod 22 is pushed. ) Is coupled to the stopper hole 26 of the throttle valve 25.

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 present invention is operated as described above, the throttle valve is fixed to a position in the stopped state of the vehicle 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.
