On the display unit 130, a volume control switch 134 for increasing or decreasing the volume of the alarm sound may be disposed. In Fig. 9, a switch for increasing the volume and a switch for decreasing the volume are arranged, respectively, but a single switch may be arranged according to the user's need.

Here, it is preferable that the volume control switch is a capacitive switch that senses a change in capacitance when the user's body is touched and is operated in accordance with the change. The electrostatic capacity switch used in this embodiment uses a method in which the electrostatic capacitance is changed and manipulated according to the degree of compression of the spring.

The capacitive switch is a publicly known technology, and thus a detailed description thereof will be omitted.

As described above, the display unit 130 may display various pieces of information about the opponent vehicle traveling in front, back, left, and right of the vehicle according to the user's need.

An operation switch or the like may be disposed on the display unit 130. [

The alarm unit 140 outputs various alarm signals according to the distance to the opponent vehicle converted by the control unit 120. [ The alarm unit 140 may output a warning sound of a predetermined volume through a predetermined speaker.

An example of the alarm signal output from the alarm unit 140 is as follows.

In the case where the calculated distance is 6 to 7 m, no warning sound is output, and the display unit 130 displays the surroundings around the vehicle and the first to tenth ultrasonic sensors 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110) may be output. In addition, the distance converted through the display unit 130 can be displayed.

Step 2: If the converted distance is 5.1 m to 6 m, no warning sound is output, and the distance sensed by the distance sensing unit 110 may be blinked on the display unit 130. In addition, the distance converted through the display unit 130 can be displayed.

Step 3: If the converted distance is 4.1 ~ 5m, the warning sound may be output intermittently (for example, 2 seconds). In addition, the distance converted through the display unit 130 can be displayed.

Step 4: If the converted distance is 3.1 ~ 4m, the output sound interval of the previous step may be output (for example, 1.5 seconds). In addition, the distance converted through the display unit 130 can be displayed.

Step 5: If the converted distance is 2.1 ~ 3m, the output sound interval of the previous step may be output (for example, 1 second). In addition, the distance converted through the display unit 130 can be displayed.

Step 6: If the converted distance is 1.1 ~ 2m, a beep sound with a higher output interval than the previous step is output (for example, 0.5 second), and a warning sound may be output to prepare for stopping. In addition, the distance converted through the display unit 130 can be displayed.

Step 7: If the converted distance is 0.4 ~ 1m, a warning sound with a faster output interval than the previous step may be output (for example, 0.2 second), and a warning sound may be output to notify the stop. In addition, the distance converted through the display unit 130 can be displayed.

Step 8: If the converted distance is 0.4m or less, a continuous warning sound is output from the previous step, and a voice warning sound indicating that the emergency is generated may be output. In addition, the distance converted through the display unit 130 can be displayed.

The alarm level of the alarm unit 140 may be further subdivided according to the needs of the user, and the output interval and volume of the alarm sound and the display mode through the display unit 130 may be changed according to the user's need.

Also, as the alarm level is raised, the volume of the alarm sound may gradually increase.

When the distance to the opponent vehicle is more than 5 m, the control unit 120 may maintain the warning sound output for a predetermined time (for example, 1 to 2 seconds) while the control unit 120 outputs the alarm signal to the alarm unit 140 have.

The alarm operation interrupter 144 turns on / off the operation of the alarm unit 140 by the user's operation. In other words, if there are many vehicles in the vicinity of the vehicle during driving, the alarm sound may continuously be generated to interfere with the safe operation, so that the user can operate the alarm operation interrupter 144 to prevent the alarm sound from being output . The operation of the distance sensing unit 110 and the control unit 120 is not turned off even when the alarm operation interrupter 144 is turned off

However, if it is determined by the third ultrasonic sensor 1103 and the fourth ultrasonic sensor 1104 that there is a predetermined object in the dead zone of the side mirror, the control unit 120 determines whether or not the alarm operation interrupter 144 is operated The operation of the alarm unit 140 is turned on. Here, in the blind spot of the side mirror, a passenger car having a lower height than the bus where the person is located or the present invention is used can be located.

The directional operation sensing unit 150 senses the operation of a directional indicator operation lever (not shown) for blinking a directional indicator for informing the directional switch to the surrounding vehicle when the vehicle switches its travel direction to the left or right, And outputs it to the control unit 120.

When the operation of the alarm unit 140 is turned off by the alarm operation interrupter 144, the controller 120 receives the signal from the directional operation sensing unit 150, And outputs the detection result through the display unit 130.

The GPS receiving unit 160 receives the GPS signal and outputs information on the road currently being operated to the control unit 120. That is, the GPS receiving unit 160 outputs to the control unit 120 a signal indicating whether the road currently being driven by the GPS signal is a city road, a general highway, a private road, or a highway.

The control unit 120 divides the driving of the vehicle into a high-speed driving mode through a vehicle-specific road or a highway and a general driving mode through a general road, and drives the vehicle-dedicated road or highway using signals output from the GPS receiving unit 160 The operation mode is set to the high-speed running mode.

In setting the high-speed driving mode, the control unit 120 converts the distances to the opponent vehicle using the signals output from the third to sixth ultrasonic sensors 1103, 1104, 1105, and 1106 disposed on the sides of the vehicle, do.

The control unit 120 sets the traveling mode to the normal traveling mode when it is determined that the vehicle is traveling on the city road or the general highway using the signal outputted from the GPS receiver 160. [

When setting the normal traveling mode, the distance between the vehicle and the opponent vehicle is converted using the signals of the first to tenth ultrasonic sensors and outputted.

On the other hand, even when the vehicle travels on a city road or a general highway, it is possible to travel at a speed higher than a predetermined speed if the traffic volume is small.

Accordingly, the display unit 130 may be provided with a mode selection switch 136 that can select a high-speed driving mode and a general driving mode through a general road by a user's selection so that the driver can select the driving mode according to the driving conditions desirable.

The use of the mode selection switch 136 will be described.

When the user starts the engine of the vehicle to drive the vehicle, the vehicle anti-collision warning device according to the present invention may be set to the normal running mode at the beginning of engine operation.

Thereafter, when the vehicle enters the general road, the user can select the normal driving mode by turning off the mode selection switch 136. [ When the general traveling mode is selected, the traveling mode display unit 132 is turned ON and the first, second, seventh, eighth, ninth and tenth ultrasonic sensors 1101, 1102, 1107, 1108, 1109 and 1110 ) Can be operated to detect the front and rear opponent vehicle.

The sensing unit 170 measures the traveling speed of the vehicle and outputs the measured speed to the control unit 120. That is, when the vehicle travels in the city road or the general highway, the speed limit is 60 to 80 km, but the speed limit is higher than that of the expressway or the exclusive road.

Therefore, even when a predetermined distance to the opponent vehicle is detected as being distanced by a distance, the alarm signal output step of the vehicle can be adjusted upward according to the running speed of the vehicle when the running speed of the vehicle is equal to or greater than a predetermined speed.

When the vehicle is detected as a constant speed running signal at 60 km from the city road by the output signal of the sensing unit 170 and the distance converted from the distance to the opponent vehicle by the output signal of the distance sensing unit 110 is 2.1 to 3 m, The control unit 120 outputs a control signal so that an alarm of five levels is output. When the distance from the opponent vehicle is calculated based on the output signal of the distance sensing unit 110 from 2.1 to 3 m, it is detected by the output signal of the sensing unit 170 that the vehicle is traveling at a constant speed of 100 km on the highway. The control unit 120 outputs a control signal so that an alarm of six stages is output.

The emergency light motion detection unit 180 detects whether the vehicle emergency light is operating and outputs a signal corresponding to the emergency light operation to the control unit 120. [ The control unit 120 receives the output signal of the emergency lighting operation sensing unit 180 and causes the display unit 130 to sustain the display operation and stops the generation of the alarm sound through the alarm unit 140.

The reverse gear sensing unit 190 outputs a corresponding signal to the control unit 120 when the transmission gear of the vehicle is set to reverse. The control unit 120 receives the output signal of the reverse gear sensing unit 190 and outputs a control signal to the alarm unit 140 to output a predetermined warning sound.
