Description

Automatic external alarm circuit driving condition when driving on the slope of the vehicle

The present invention relates to an automatic external alarm circuit for driving state when driving a vehicle in detail, and more particularly, to an external external alarm for driving state of a vehicle that automatically alerts the outside when the vehicle stops or rotates while driving the ramp. It is about a circuit.

In general, slopes such as mountain roads or hills are often one-round or narrow roads, which require high tension in the operation of the vehicle and often require rotation due to the terrain characteristics. The car must be rotated carefully, and in some cases the horn should be activated to inform the outside of the vehicle's running.

However, in the related art, when the vehicle stops or rotates the slope while driving, there is no device that automatically alerts the outside, so when driving on a slope that requires frequent rotation such as a mountain road, it is manually operated at every turn to turn on the turn signal lamp. In some cases, there is a troublesome problem of warning the outside of the vehicle by operating the horn by manual operation.

The present invention has been made to solve the above problems, and provides a circuit that automatically alerts the outside when the vehicle is running on a slope or stops, and turns the turn signal lamp on every turn and turns on. Accordingly, the object of the present invention is to provide a more comfortable drive environment by eliminating the troublesome problem of operating the horn manually.

The present invention, in order to achieve the above object, the sensing unit for detecting a driving state of the vehicle; E. C. U for controlling the alarm function according to the detection value of the detection unit; A switching unit performing a switching operation under the control of the E. C. U; According to the operation of the switching unit is characterized in that made of an alarm unit for externally warning the driving state of the vehicle.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a circuit diagram according to an embodiment of the present invention, the input terminal of the EC U (20) is connected to the output terminal of the sensing unit 10 for detecting the driving state of the vehicle, the output terminal of the EC U 20 is a switching unit It is connected to the two transistors (TR1, TR2) of the base terminal of the 30, respectively, the collector terminal is applied to the Vcc power supply, the emitter terminal is connected to the electromagnet grounded the other end of the two relays (RY1, RY2), respectively, A B + power supply is applied to one end of the switches of the two relays RY1 and RY2, and the other end is connected to the horn 41 and the turn signal lamp unit 43 grounded at the other end of the alarm unit 40.

The detection unit 10 of the present invention is to determine the steering angle of the steering wheel by the driver and the brake detection sensor 13 for detecting the inclination sensor 11 for detecting the inclination angle of the road driving and whether the brake pedal is driven by the driver. It consists of a handle angle sensor 15 to detect.

The alarm unit 40 of the present invention includes a horn 41 for generating an alarm sound and a turn signal lamp unit 43 for indicating a rotation direction of the vehicle.

Hereinafter, the operation of the present invention configured as described above.

When the inclination of the road surface being driven is input to the EC U 20 by the inclination sensor 11 which detects the inclination of the road surface while the vehicle is being inclined, the EC U 20 determines that the vehicle is driving the inclination and handle angles. The steering angle of the steering wheel by the driver is input through the sensor 15. At this time, when the driver drives the brake pedal and the brake detection sensor 13 detects this and inputs it to the EC U 20, the EC U 20 applies a bias power to the base end of the transistor TR2 so that the transistor ( TR2) is in a conductive state, and the magnetic field is formed in the electromagnet of the relay RY2 by supplying the Vcc power applied to the collector end to the electromagnet of the relay RY2, so that the switch crosses the relay RY2. Is supplied to the turn signal lamp unit 43 to turn on the turn signal lamp.

In addition, when the driver does not drive the brake pedal, the EC U 20 applies bias power to the base ends of the two transistors TR1 and TR2 so that the two transistors TR1 and TR2 are in a conductive state. Again, the two transistors TR1 and TR2 supply Vcc power to the electromagnets of the two relays RY1 and RY2 so that a magnetic field is formed in the electromagnet to cross the switch, so that the two relays RY1 and RY2 are applied to B +. Power is supplied to the horn 41 and the turn signal lamp unit 43 to turn on the turn signal lamp and operate the horn 41.

When the driver changes the steering angle of the steering wheel to rotate the vehicle, the steering angle sensor 15 detects this and inputs the steering wheel to the EC U 20. The EC U 20 determines the rotation of the vehicle to determine the transistor TR2. By applying a bias power to the base end of the transistor), the transistor TR2 is in a conductive state, and a magnetic field is formed in the electromagnet of the relay RY2 by supplying the Vcc power applied to the collector end to the electromagnet of the relay RY2. Since the cross is crossed, the relay RY2 supplies the applied B + power to the turn signal lamp unit 43 to turn on the turn signal lamp.

As described above, according to the present invention, when the vehicle stops or rotates while driving on the slope, the driver automatically alerts the outside through a turn signal lamp or a horn. In some cases, the troublesome problem of having to operate the horn is solved, thereby providing a more relaxed drive environment.
