The present invention relates to an anti-vehicle device on a slope, and more particularly, to prevent the vehicle from being pushed when the vehicle pauses and starts on the slope, so that even a novice driver who operates a manual transmission can effectively start on the slope. It relates to a vehicle skid prevention device on the slope.

In general, a vehicle is provided with an internal combustion engine such as a gasoline engine or a diesel engine as a power generating device for driving the vehicle, and the power (torque) of the power generated in the internal combustion engine is adjusted as an accelerator pedal. In addition, the vehicle is provided with a clutch that transmits or cuts engine power to the drive wheels and a transmission that increases or decreases the driving force according to the driving state of the vehicle as a power transmission device, and a brake device that slows or stops the speed of the vehicle being driven. Is installed.

Among the above devices, the pedal for operating the clutch and the pedal for controlling the brake are respectively installed as pedals at the bottom of the driver's seat together with the accelerator pedal, and are operated by the foot. The shift lever should be operated, the right pedal should be operated with an accelerator pedal and a brake pedal, and the left foot should be operated with a clutch, which is the case with a vehicle equipped with a manual transmission. In addition to the automatic transmission lever, there is only a right pedal operated pedal and brake pedal, there is no clutch pedal.

However, in the case of a vehicle equipped with a manual transmission, if you are going up a ramp and want to stop due to a signal or traffic jam or a sudden accident, first press the clutch completely with your left foot so that the engine power is not transmitted to the wheels. You must step on the pedal with your right foot to keep the engine from stopping.

In this case, the brake device of the vehicle is generally described as a passenger car, and the front wheel uses a disc brake that grips both sides of the wheel disk with a pad, and the brake wheel operated by the wheel cylinder of the back plate opens on the rear wheel. The drum brake is used to brake when it is in close contact with the brake pad. When the brake pedal is released, the pad of the front wheel falls off the wheel disk, and the brake shoe of the rear wheel is configured to release the braking force as it falls off the inner peripheral surface of the drum.

Therefore, in the conventional brake system, the braking force of the brake is immediately released when the foot is released from the pedal, and when the vehicle is stopped on the slope and the brake pedal is released, the vehicle is pushed back by its own weight.

Therefore, if you want to start more smoothly, release the clutch pedal on your left foot slightly to create a half-clutch state, and then move the right foot on the brake pedal quickly to the accelerator pedal, and then release the clutch pedal on your left foot completely before the power gear is released. The vehicle will move forward while being bitten. At this time, if you press the accelerator pedal too quickly and release the clutch pedal, it will turn off the engine.

Therefore, smooth operation of each of these pedals requires a very skilled skill, and for the novice driver, the most difficult part is the time to stop and start again. In this way, the vehicle cannot start after stopping at the slope. If the driver pushes the vehicle backwards, the new driver may be very embarrassed about the collision with the driver behind the car, and further impede the congestion as it hinders the flow of the vehicle.

In particular, when the start of such a slope lasts for a long time due to the congestion of the vehicle, the beginner driver as well as the driver who drives the aging vehicle and the overload vehicle are severely stressed with the foot and leg fatigue.

And, due to the above problems, many drivers currently prefer an automatic transmission vehicle that can smoothly start without stopping the start of the vehicle on the slope, but when the automatic transmission is equipped with a manual transmission in the future Although the vehicle price is higher than that of the vehicle, fuel consumption is increased by about 20% when the vehicle is shipped after leaving the factory, which causes a lot of maintenance costs.

The present invention is a vehicle equipped with a manual transmission to stop the vehicle when starting from the ramp to stop the start of the vehicle in the slope even if the operation of the clutch pedal, brake pedal, accelerator pedal is poor beginners It is an object of the present invention to provide a vehicle skid prevention device on a slope that can be moved more smoothly without a trillion.

Another object of the present invention is that even if a skilled driver does not increase the RPM of the engine up to 2000-3000 instantaneously when starting from the slope, the jungle does not occur, so that the start is made, unnecessarily excessive consumption of fuel is made An object of the present invention is to provide an anti-vehicle vehicle on a slope.

An object of the present invention is a vehicle speed sensor 600 for detecting a driving speed of the vehicle, a vehicle tilt sensor 500 for detecting the inclination of the vehicle in which the vehicle speed sensor 600 is installed, the vehicle speed detection BCM (300) for outputting a signal to change the viscosity of the ER fluid 200 and at the same time outputting a signal to adjust the RPM of the engine to an appropriate level according to the value detected by the sensor 600 and the vehicle tilt sensor 500 And the brake pedal 100 rotating around the fixed shaft 130 around the fixed shaft 130 according to the viscous state of the ER fluid 200, and the braking force of the brake according to the rotation state of the brake pedal 100. Is achieved by the configuration of a booster 400 to maintain and release.

According to the present invention, the vehicle speed sensor 600 and the vehicle tilt sensor 500 detect the inclination of the vehicle speed and the vehicle, respectively, when the vehicle is stationary on the incline, and the vehicle speed sensor 600 and the vehicle tilt. According to the value detected by the sensor 500, the BCM 300 outputs a signal such that the RPM of the engine and the viscosity of the ER fluid 200 are in an appropriate state, and according to the viscosity state of the ER fluid 200. The brake pedal 100 generates and releases a braking force of the booster 400 while the front and rear portions of the compartment are rotated about the fixed shaft 130.

Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail as follows.

1 is a configuration diagram showing the vehicle rolling prevention device on the incline of the present invention, Figure 2 is a side view showing the installation state of the brake pedal for vehicle rolling prevention device on the incline of the present invention, Figure 3 is a vehicle on the incline of the present invention Front view showing a brake pedal for a skid prevention device.

Figure 4 is an enlarged main portion showing the upper portion of the brake pedal for vehicle rolling prevention device on the incline of the present invention, Figure 5 is a flow chart showing the operating state of the vehicle rolling prevention device on the incline of the present invention.

As shown in FIG. 1, the apparatus for preventing vehicle rolling on the slope of the present invention detects the inclination of the vehicle in which the vehicle speed detection sensor 600 and the vehicle speed detection sensor 600 are installed to detect the traveling speed of the vehicle. The vehicle tilt sensor 500 and the vehicle speed sensor 600 and the vehicle tilt sensor 500 according to the value detected to output a signal to adjust the engine RPM to an appropriate level and at the same time ER fluid 200 BCM (300) for outputting a signal to change the viscosity of the) and the brake pedal 100 is rotated to the front and rear of the vehicle around the fixed shaft 130 in accordance with the viscosity state of the ER fluid 200, It is composed of a booster 400 for maintaining and releasing the braking force of the brake according to the rotation state of the brake pedal 100.

Meanwhile, as illustrated in FIGS. 2, 3, and 4, the ER fluid 200 is filled in the hollow housing 700, and the signal output from the BCM 300 is provided to the housing 700. In accordance with the on-off is made is a switch 710 for supplying and cutting off the power so that the viscosity of the ER fluid 200 is changed, the ER fluid 200 is changed in viscosity depending on the on-off state of the switch 710 The inside of the housing 700 is filled therein is a fixed shaft 130 is rotatably coupled to the upper end of the pedal arm 110 of the brake pedal (100).

In addition, the brake pedal 100 when the viscosity of the ER fluid 200 which is filled in the housing 700 on both sides of the upper and left sides of the pedal arm 110 of the brake pedal 100 hinged to the fixed shaft 130 is strong. ) Is formed so as to protrude outward wing piece 120 to move in the direction to press the rotary gear booster 400 around the fixed shaft 130.

On the other hand, the BCM (300) is the vehicle speed is detected by the vehicle speed sensor 600, the vehicle tilt is detected only when the vehicle tilt detected by the vehicle tilt sensor 500, 10 ° or more and at the same time ER fluid 200 Note that the signal outputs to increase the viscosity of the).

According to the present invention configured as described above, when the vehicle traveling on the ramp presses the brake pedal to stop once due to a signal, a traffic jam, or a sudden accident, the booster 400 is operated to stop the vehicle.

At this time, the vehicle speed sensor 600 and the vehicle tilt sensor 500 is input to the BCM 300 by detecting the vehicle driving speed and the inclination of the vehicle, respectively, the BCM 300 is the vehicle speed sensor 600 and When the vehicle speed detected by the vehicle tilt sensor 500 is "0" and the vehicle is inclined at 10 ° or more, the engine 700 is raised to be 1000 and the viscosity of the ER fluid 200 is increased at the same time. Turn on the switch 710 installed.

When power is supplied to the enclosure 700 by turning on the switch 710, the pedal arm 110 of the brake pedal 100 becomes stronger as the ER fluid 200 is discharged from the enclosure 700. The wing piece 120 is pressed to rotate about the fixed shaft 130 in the brake operation direction.

In order to start the vehicle again in this state, as described above, the foot must be moved from the brake pedal 100 to the accelerator pedal. As soon as the foot is released from the brake pedal 100, the brake pedal 100 pressurizes the booster 400. The vehicle is prevented from being pushed back even when the foot is released from the brake pedal 100 because it is maintained as it is.

Then, when the vehicle starts by pressing the accelerator pedal, since the vehicle speed is "0" or more, the power supplied to the enclosure 700 in which the ER fluid 200 is filled in the BCM 300 is switched off 710. By turning off the switch, the power is not supplied to the ER fluid 200 by the switch off, the viscosity is weakened, the brake pedal 100 is operated with the normal operating force as usual.

As described above, the present invention can effectively start by avoiding the rolling of the vehicle when starting and stopping on the slope as a vehicle equipped with a manual transmission, that is, without using an automatic transmission, which is expensive and low fuel economy. For beginner drivers who are not good at clutch pedals, brake pedals and accelerator pedals, the vehicle can run more smoothly without turning off the vehicle on the slopes, so that the flow of the vehicle can be maintained more smoothly. Because of this, even if the departure from the slope lasts for a long time, many drivers can operate the vehicle smoothly without being physically and mentally stressed.
