Automatic braking system by opening the hood of the car

The present invention relates to an automatic braking system according to the opening of the hood of a vehicle, and more particularly, to inform the driver of the opening state of the hood by using a warning light on the instrument panel, and also to operate the hydraulic brake using the plate of the brake booster. Since the vehicle is stopped, the present invention relates to an automatic braking system according to the opening of the hood of the vehicle, which is configured to prevent the risk of an accident due to the opening of the hood while driving the vehicle.

In general, if the driver operates the vehicle without recognizing the hood's opening while the hood of the vehicle is open, there is a risk of an accident because the hood is opened to cover the driver's vision, and even the acceleration causes the hood to be removed from the vehicle body. If you fall off, you can damage the windshield of the car and cause serious injuries.

Therefore, the present invention has been devised in view of the above problems, by installing a button that is pressed according to the opening and closing of the hood between the vehicle body and the hood to inform the driver of the open state of the hood through a warning light on the instrument panel, and also measured by the speedometer When the speed of a vehicle is detected at a certain speed or more, the electromagnet inside the brake booster is magnetized, and at the same time, the hydraulic pressure is transmitted to the brake means through the intake manifold due to the plate movement, so that the brake can be activated to automatically stop the vehicle. An object of the present invention is to provide an auto brake system for a vehicle configured to prevent the risk of an accident due to the opening of a hood while driving a vehicle.

1 is a schematic diagram of an automatic braking system according to the opening of a hood of a vehicle according to the invention;

Hereinafter, the configuration of the present invention will be described with reference to the accompanying drawings.

According to the present invention, in an automatic braking system of an automobile, a button 12 is turned on / off according to opening and closing of a hood on a vehicle body in which a hood is pressed, and connected to a first relay 14, The warning lamp 18 of the instrument panel can be turned on according to whether or not the button 12 is pressed, and the contact part 22 and the contactor 24, which are mounted in the speedometer 20 and operate according to the speed, are operated. Since the operation of the second relay 16 is determined by this, the electromagnet 36 in the brake booster 30 is magnetized by the power of the battery 10 so that the hydraulic pressure is transferred through the intake manifold 38 by the movement of the plate 32. And to be transmitted to the brake means.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

According to the present invention, the button 12 which is pressed according to the opening and closing of the hood is installed on the vehicle body on which the vehicle hood is pressed, and the first relay 14 which is controlled according to whether the button 12 is pressed is installed.

In addition, a warning lamp 18 that is turned on according to the operation of the first relay 14 is installed in the instrument panel, and at the same time, the inside of the speedometer 20 sensing the operation of the first relay 14 and the speed of the vehicle. The contact part 22 and the contactor 24 which are means are provided.

On the other hand, the second relay 16 whose magnetization is determined by the contact means is connected with the electromagnet 36 of the brake booster 30 so that the magnetized electromagnet 36 pulls the plate 32 so that the hydraulic pressure is intake manifold. It has a structure which is transmitted to the brake means via the hold 38.

According to the present invention, when the driver drives the vehicle while the hood of the vehicle is not closed, the first relay 14 is closed because the button 12 installed in the hood portion of the vehicle that contacts the vehicle body is not pressed. The power from 10) is configured to be energized.

In this case, since the first relay 14 uses a normal close, the first relay 14 opens only when a signal is applied.

Thus, the warning light 18 of the instrument panel is turned on so that the driver can know that the hood of the vehicle is running with the hood open.

At this time, since the vehicle is running, the speedometer 50 may measure the speed of the vehicle, and the connection signal between the contact portion 22 and the contactor 24 is input to the second relay 16, and power is supplied to the second relay ( As the electromagnet 36 of the brake booster 30, which is driven 16 and receives the signal thereof, is operated, the plate 32 is moved toward the electromagnet 36 by the spring 34 to fill the brake booster 30. The hydraulic pressure is sent to the wheel cylinders on the wheels and the brakes are actuated to stop the vehicle automatically.

Meanwhile, since the button 12 is pressed while the hood of the vehicle is closed to the vehicle body, the power of the first relay 14 is cut off and the operation of the system is stopped.

As described above, the present invention relates to an automatic braking system according to the opening of a hood of a vehicle, which notifies the driver of the opening state of the hood and is configured to automatically brake the vehicle to be operated while the hood of the vehicle is opened while driving. In this case, it is possible to prepare for a large accident due to obstruction of view.

Claims (1)

A button 12 that is turned on / off in accordance with opening and closing of the hood is installed on the vehicle body in which the hood is pressed, and connected to the first relay 14, and according to whether or not the button 12 is pressed. The operation of the second relay 16 is determined by the contact portion 22 and the contactor 24, which are configured to enable the warning lamp 18 to light up and are mounted in the speedometer 20 and operate according to the presence or absence of speed. Therefore, the electromagnet 36 in the brake booster 30 is magnetized by the power of the battery 10 so that the hydraulic pressure is transmitted to the brake means through the intake manifold 38 by the movement of the plate 32. Automatic braking system by opening the hood of the car.
