The present invention relates to a device for displaying a driving direction to predict the driving direction according to the direction of the front wheel when driving the vehicle to drive safely and to generate an alarm sound when going to the left or right direction.

In general, when starting a parked vehicle, the driver's seat cannot identify the direction of the front wheels, and thus, it is impossible to predict in which direction the vehicle will start. Therefore, there was a possibility of accidentally predicting the direction of departure in case of a quick departure and causing traffic accidents by entering the next car or hitting a pedestrian.

Accordingly, the present invention has been made in order to solve the above-mentioned conventional problems, display the driving direction according to the direction of the front wheel when the vehicle starts to display the driving direction so that the driver can know the driving direction and the alarm The purpose is to provide a device.

In order to achieve the above object, the present invention provides a direction indication and warning device comprising: a decoder for outputting a direction signal by decoding a direction signal of a steering sensor; A speed detector for detecting a speed below a predetermined speed by inputting a speed signal; A direction display unit for inputting a gear position signal, the direction signal, and the output of the speed detector to display a direction of a front wheel and a traveling direction of the vehicle; And an alarm sound generator configured to input an output of the direction signal and the output of the speed detector and generate an alarm sound when the vehicle proceeds to the left or the right when the vehicle starts.

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

1 is a view showing a screen in a cluster showing a traveling direction when a vehicle starts according to the present invention, which shows the exterior of a vehicle in the center and shows four doors: front, rear, front and rear on the side of the vehicle. It can display the open state of the door, and can show the forward direction by showing three arrows (1 to 3) on the front of the vehicle shown, and display three arrows (7 to 9) on the rear of the vehicle shown In this case, the reverse direction is shown, and three rectangles 4 to 6 are respectively shown at the pair of front wheel positions of the vehicle to show the direction of the front wheels.

FIG. 2 is a circuit diagram illustrating a progress direction display and an alarm device when the vehicle starts according to the present invention, and includes: a decoder 10 for decoding direction signals of a steering sensor and outputting direction (R, C, L) signals; A speed detection unit 20 for detecting a speed below a predetermined speed by inputting a speed signal; A direction display unit (30) for inputting a gear position (D, R) signal, the direction (R, C, L) signal, and the output of the speed detector 20 to display the direction of the front wheel and the traveling direction of the vehicle; And an alarm sound generator 40 which generates an alarm sound when the direction (R, C, L) signal and the output of the speed detector 20 are input and proceed to the left or the right when the vehicle starts.

The operation of the apparatus of the present invention configured as described above with reference to FIGS. 1 and 2 is as follows.

The direction decoder 10 inputs a signal from a steering sensor and when it is located at the center, outputs the direction C signal high, and if it is biased to the right, outputs the signal R to high and if it is biased to the left Outputs the leftward (L) signal high.

The speed detector 20 outputs a high speed when the vehicle speed is smaller than the set reference speed and a low value when the speed is smaller than the set reference speed signal after inputting the speed signal.

The speed set in the embodiment of the present invention is 10Km / H, and when the vehicle speed is less than 10Km / H as in the departure, the direction indication and the alarm function according to the present invention are executed, and the direction is displayed when driving at 10Km / H or more. And do not perform alarms. That is, when the direction of the front wheel is biased to the left or right at the start of the vehicle, the present invention is to recognize the driver so as to prevent contact accidents with the adjacent vehicle. Therefore, the direction display function according to the present invention is required during normal driving. There will be no. Therefore, the speed detector 20 of the present invention outputs high or low to execute the direction indication and the alarm only at or below the set speed.

The direction display unit 30 advances to display the forward direction by lighting one of the arrows 1 to 3 of FIG. 1 according to the output of the direction decoder 10 at the time of the forward movement (that is, when the gear position signal D is high). In response to the output of the direction display section 32 and the direction decoder 10, one of the quadrangles 4 to 6 of FIG. 1 is turned on to indicate the direction of the front wheels, and the reverse direction (i.e., the gear position signal). When R is high), it is divided into a backward direction display section 36 which lights one of the arrows 7 to 9 in FIG. 1 to indicate the reverse direction in accordance with the output of the direction decoder 10. FIG.

The operation of the direction display unit 30 configured as described above is summarized in Table 1 below.

As shown in Table 1, when the gear position signal D is high (H) when moving forward, the gear position signal R is high (H) when moving backward, and the speed detection signal is high (H) when it is less than 10 km / H as at the start. )to be. Therefore, forward and backward are discriminated by the gear position signal, and the direction display unit 30 according to the present invention operates only when the speed detection signal is high.

That is, the first AND gate AND1 logically multiplies the left L signal, the speed detection signal, and the gear position signal D of the direction decoder 10 to turn on the lamp L1 when all inputs are high. The arrow 1 of FIG. 1 is brightened, and the fourth and gate AND4 logically multiplies the leftward L signal and the speed detection signal of the direction decoder 10 by the ramp L4-1 when all the inputs are high. , L4-2) is turned on to make the rectangle 4 of FIG. 1 bright so that the driver can recognize the driving direction and the direction of the front wheel.

Hereinafter, operations from the second and gate AND2 to the ninth and gate AND9 are similar to those of the first and gate AND1 and the fourth and gate AND4, and the operations thereof are shown in Table 1 above. The description will be omitted.

The alarm sound generating unit 40 inputs a left (L) and a right (R) signal and a speed detection signal from the direction decoder 10, and then the vehicle proceeds to the left and right at the time of forward (D) and reverse (R). In this case, the alarm circuit 42 sounds the buzzer 44 to generate an alarm sound (for example, a dense sound) to call the driver for attention. As described above, the present invention informs the driver in advance of the direction of the front wheel and the forward and backward movement at the time of departure of the vehicle being parked, and when the vehicle moves to the left or right direction, the driver's attention is alerted by an alarm sound to cause the accident It is effective in preventing the accident and enabling safe driving.
