The switch 74 and the like are electrically connected. The road surface state input unit 20 detects a road surface state of the braking distance of the vehicle and transmits an electrical signal to the control unit 10. This is a large number for informing whether the road surface is normal or wet or frozen in the rain, whether the fog is present or the like. It consists of two keys. The vehicle state detecting unit 30 inputs information related to the mounting of the antilock brake system, the driving state of the own vehicle, and the like. The driving state of the own vehicle is input through a sensor for detecting whether the vehicle is driving on a curved road, a sensor for detecting whether the brake is operating, and a sensor for detecting whether the vehicle is turning left or right. Meanwhile, an obstacle such as a vehicle approaching the vehicle is detected through a sensor 40 installed at a corner of the vehicle, which is a front left corner detection sensor 41 and a front right corner detection sensor 42 and a rear left side. It consists of a corner detection sensor 43 and the rear right corner detection sensor 44 and the like to detect an obstacle such as a vehicle within a predetermined distance to these areas and transmits an electrical signal to the control unit 10. In addition, the mode selection switch 74 is a button switch which controls so that it may appear to the time display control part 71 and the difference distance display control part 73 mentioned later.

In addition, the output unit of the control unit 10 is connected to the clock 70 to display the time or the distance between the display unit 73 and the alarm sound generating unit 60 for warning the driver acoustically.

The alarm sound generating unit 60 is based on the signals input from the inter-vehicle distance detecting unit 50, the road surface state detecting unit 20, and the vehicle state detecting unit 30. If it is determined that the distance between the own vehicle and the preceding vehicle is less than the stopping distance by calculating the relative speed, road surface speed, and the stopping distance of the own vehicle, an alarm sound is generated to alert the driver acoustically. In addition, the vehicle clock 70 is mounted on the instrument panel A provided on the front of the driver's seat so that the driver can easily see, and is configured to selectively display the distance or general time between the host vehicle and the preceding vehicle.

The operator is visually warned, which is explained in detail in the operating instructions.

The following describes the operation and effects of the collision avoidance device and the clock of the vehicle configured as described above.

First, when the driver turns on the ignition key, the controller 10 performs initialization, and recognizes the road surface state and displays the current time in numerical value on the display unit 73 of the clock 70 by the time display controller 71.

When the vehicle is driven in this state, the inter-vehicle distance detecting unit 50 detects the distance to the preceding vehicle in the front side of the host vehicle and inputs it to the controller 10. The controller 10 receiving the distance between the host vehicle and the preceding vehicle calculates the stopping distance in consideration of the speed of the host vehicle, the relative speed between the host vehicle and the preceding vehicle, and the state of the road surface. If the vehicle does not operate the brakes, does not change the direction, and is not driving on a curved road, the vehicle is less than the stopping distance. When the alarm sound generator 60 is activated to alert the driver acoustically.

At this time, when the driver presses the mode selection switch 74 to accurately know the distance between the host vehicle and the preceding vehicle, the operation of the time display control unit 71 is stopped and the inter-vehicle distance display control unit 72 is operated. Accordingly, the inter-vehicle distance display control unit 72 receives the inter-vehicle distance between the preceding vehicle and the host vehicle from the control unit 10 and outputs a control signal to display the inter-vehicle distance numerically on the display unit 73, whereby the driver may decelerate the speed. It is possible to drive safely by changing driving lanes. At this time, since the normal inter-vehicle distance is displayed only when it is 99 meters or less, it is displayed on the part which shows minutes of time.

On the other hand, when obstacles, ie, other vehicles, are adjacent to the front left and right corner adjacent parts or the rear left and right corner adjacent parts of the vehicle, the detection sensors 41, 42, 43, and 44 installed at each corner of the corresponding part of the vehicle detect and control the controller. Input electrical signal to (10). Therefore, when an obstacle is close to the host vehicle and an electrical signal is input to the control unit 10 from the sensing sensors 41, 42, 43, 44, the display corresponding to the position of the sensing sensors 41, 42, 43, 44 with the signal input thereto. By turning on the lights 75, 76, 77, and 78, the driver can easily recognize the approach direction of the obstacle.

As a result, the space utilization of the instrument panel A is improved by displaying the distance between the own vehicle and the preceding vehicle using the vehicle clock 70 mounted on the instrument panel A provided on the front of the driver's seat without using a separate display unit. You can. In addition, indicators 75, 76, 77, and 78 are provided at four corners of the display unit 73 of the clock 70, so that when there is an obstacle approaching the host vehicle, the indicators 75, 76, By turning on 77 and 78, the driver can easily know the direction of obstacle proximity.

As described above in detail, the vehicle clock displaying the inter-vehicle distance and the obstacle position according to the present invention may display a normal time or a distance between the own vehicle and the preceding vehicle through a mode selection switch operation on a display unit, and the four corners of the display unit. Indicators are provided to indicate the direction of approach by turning on obstacles near the site.

Therefore, since the distance between the preceding vehicle is displayed through a commonly used vehicle clock, the space utilization of the instrument panel is improved, and the overall manufacturing cost of the vehicle is reduced without requiring a separate display unit. In addition, the presence of obstacles in the front, rear, left and right corners of the blind spot can easily recognize its approach position through the indicator has the advantage of preventing the vehicle accident in advance.
