The present invention relates to a vehicle collision prevention device and method for releasing.

Accidents in automobiles are directly related to the lives of drivers and passengers, so car accidents are a serious problem behind the convenience of automobiles. Therefore, various safety equipments are being developed for automobile accidents, which are intended to save lives in the event of an accident. However, the risk of accidents may be reduced, but there is no function to prevent accidents.

In a conventional vehicle, side back mirrors are used on the left and right sides of the vehicle to determine the situation of the side and the rear of the vehicle. In general, the side back mirror of the vehicle is a blind spot that cannot be identified by the side back mirror when viewed from the driver's seat. Because there is a zone, the driver should turn his head to check the blind spot in the case of lane change, etc., so that an accident may occur because it is unable to detect a dangerous situation in front and the side back mirror may be difficult to see in bad weather. There was a problem.

An object of the present invention is to solve the above-mentioned problems, in particular, by installing an infrared sensor device that can detect the distance between the front and rear of the vehicle and measure the distance between the objects and the driver's carelessness while driving the vehicle.

Detects an object, measures a distance from the detected object, and transmits the measured information to the information processing unit 30. The information processing unit 30 receives various information from the front sensor unit 10 and the rear sensor unit 20. Judging whether there is an obstacle in front of or behind the vehicle, and calculating the distance and relative speed of the obstacle if there is an obstacle, and combining the information such as the weather condition, the vehicle speed, the princess's distance, and the braking distance to determine the optimal safety distance for each state. Based on the calculated optimum safety distance, it is determined whether or not the danger for each driving state is generated to generate an alarm sound or to give an acceleration / deceleration device driving command to take appropriate measures. And displays a variety of information according to Lee data to the driver, by driving the device acceleration and deceleration and braking device itself ever solve the risk device in accordance with the data measured in the vehicle drive unit 50, constitute the present embodiment.

Hereinafter, the operation of this embodiment configured as described above with reference to the drawings as follows.

While driving a car or other vehicle, we often see accidents caused by not seeing things or people in blind spots.

As shown in FIG. 1, two infrared sensors for detecting an object in front and an object in the front and a rear of the vehicle are installed at the front sensor unit and the rear sensor unit, respectively, and the gear of the vehicle is moved forward. The infrared sensor which is the front sensor unit 10 on the front of the vehicle operates, and when the driver puts the reverse gear, the infrared sensor that is the rear sensor unit 20 on the rear of the vehicle operates.

First, when the driver puts the gear of the vehicle in the forward direction, the infrared sensor, which is the front sensor unit 10 on the front of the vehicle is operated, and measures the distance to the obstacle located in front of the vehicle and applies the information to the information processing unit 30. In (30), the distance from the obstacle and the relative speed are calculated, and the optimal safety distance for each state is calculated by integrating information such as the weather condition, the host vehicle speed, the princess distance, and the braking distance.

After the calculation is completed by the government processing unit 30, the risk of each driving state is determined based on the optimum safety distance, and in the case of a dangerous state, a signal is applied to the display unit 40 so that the driver is close to the obstacle. The warning sound and related information are displayed to the driver to be careful, and when the driver's response time is short because the distance from the obstacle is close, the device applies a signal to the vehicle driver 50 and the device itself according to the measured data. Drive the acceleration / deceleration device and the braking device to solve the problem.

On the other hand, when the driver puts the reverse gear in order to reverse the vehicle, the infrared sensor, which is the rear sensor unit 20 on the rear of the vehicle is operated to monitor the obstacle behind the vehicle and apply it to the information processing unit 30, the information processing unit 30 Calculates the distance and relative speed from obstacles behind the vehicle, and calculates the optimal safety distance for each state by combining information such as weather conditions, own vehicle speed, princess distance, and braking distance.

After the calculation is completed by the government processing unit 30, the risk of each driving state is determined based on the optimum safety distance, and in the case of a dangerous state, a signal is applied to the display unit 40 so that the driver is close to the obstacle. The warning sound and related information are displayed to the driver to be careful, and when the driver's response time is short because the distance from the obstacle is close, the device applies a signal to the vehicle driver 50 and the device itself according to the measured data.
