In recent years, with the increase of the automobile holding capacity in China, parking spaces are increasingly tense, the problem of automobile maintenance is frequently caused, and the economic loss caused by the collision of automobile doors accounts for a large proportion. Since door opening accidents are more common in recent years, from 2010, along with continuous updating of sound waves, modern signal processing, electronic technologies and the like, the method for reducing the door opening accident rate by adopting a system structure combining signal acquisition and data processing becomes a research hotspot of an automobile active safety technology, and international automobile companies pay attention to and address the difficult problem of door opening anti-collision early warning technology successively.

The Kaiyidede company, Germany, develops an innovative vehicle door "braking system". This is a sensor-based protection system. The design objective is to reduce metal damage to the door and high insurance claims that may result from hitting nearby objects when the door is opened. Two cameras are additionally arranged at the lower end of the rearview mirror to monitor obstacles near a vehicle door, and instructions are given according to information of the obstacles received by the system to determine whether to brake the vehicle door. The main technology is a door lock system based on a video technology and combined with an electromagnetic technology. The system has the advantages that the braking of the vehicle door can be realized in the door opening process, and the safety in the door opening process is further improved.

The company named as 'addressing alarm System' of the Australian Turkey company also develops the device for door opening anti-collision early warning, the first generation DAS-Alpha System is started by releasing any safety belt, and the warning is realized by adopting light to remind people inside and outside the vehicle, wherein the warning lamp for reminding outside the vehicle is positioned in the middle of the edges of two sides of the rear windshield. The DAS-Lambda, the second generation product, is still under development, and the main technology of the website of the company is as follows, the technology of Kaiyidede company is similar to the technology of the company of Kaiyidede, and the rear movement obstacle is detected by integrating a camera in a rearview mirror.

The anti-collision device with the design only plays a role in reminding or braking the vehicle door. And in part of domestic scientific research institutions of colleges and universities, research works on signal processing and control principles of automobile door opening anti-collision early warning are developed successively, but products which are not popularized in the market at present are in the stages of experimental regularity description and anti-collision algorithm exploration under simple working conditions.

Detailed Description

The first embodiment is specifically described with reference to fig. 1 to 3, and the steering engine of the first embodiment controls a collision prevention device of a vehicle door, the device is used for measuring the opening angle of the vehicle door and the distance between the vehicle door and peripheral obstacles, and the device comprises an angle sensor 1, a distance sensor 2, a controller 3, an LCD display screen 4 and a steering engine 5;

According to the utility model, the distance sensor is arranged outside the vehicle door, and the angle sensor and the steering engine are both arranged at the hinge of the vehicle door. In this device, distance sensor measures the door foot position of door and the distance of peripheral barrier (other vehicles), calculates the door that this distance corresponds and opens and shuts the most suitable angle through controller (singlechip), and rethread angle sensor detects the door and reaches behind the most suitable angle of calculation, uses the angle of opening of steering wheel restriction door to avoid passenger and driver because of economic loss and the maintenance problem that the door collided with and leads to when the door is opened.

In the second embodiment, the collision prevention device for the steering engine controlled vehicle door according to the first embodiment is further described, and in the present embodiment, the device further includes a buzzer 6, and the buzzer 6 is used for receiving a warning signal of the controller 3.

In the third embodiment, the collision prevention device for the steering engine controlled vehicle door in the second embodiment is further described, in the second embodiment, the device further includes a warning lamp 7, and the warning lamp 7 is used for receiving a warning lamp lighting signal of the controller 3.

With reference to fig. 2 and 3:

according to the utility model, after parking, the distance sensor measures the distance between the vehicle door and the obstacle and transmits the distance to the single chip microcomputer, and the angle sensor measures the actual opening angle of the vehicle door and transmits an angle signal to the single chip microcomputer. The singlechip transmits the distance (distance) between the vehicle door and the obstacle and the actual opening angle (measured by the angle sensor) (angle) to the display screen for displaying.

In the controller, the maximum door opening angle and the maximum door opening distance corresponding to the maximum door opening angle are obtained according to different calculation formulas of different vehicles in advance. If the angle signal that angle sensor detected closes on the biggest door opening angle or the distance signal that distance sensor detected closes on the biggest distance that the door was opened, then controller drive bee calling organ and warning light send alarm signal and light warning driver, drive steering wheel action simultaneously, the opening angle of restriction door to avoid passenger and driver to take place the door and collide with when the door is opened.

After the vehicle is stopped, the distance sensor outside the vehicle door starts to work and measures the distance between the vehicle door and the peripheral obstacle, and if the distance is larger than the maximum required distance of the opening angle of the vehicle door, the circuit does not respond. On the contrary, if the distance that the outer distance sensor of car door measured after parkking is less than the biggest required distance of door opening angle, then the biggest angle that the door was opened is calculated out to the distance that the singlechip was surveyed according to distance sensor to with signal transmission to steering wheel, make the steering wheel cooperate reach under the condition of angle sensor and open the biggest angle, the warning light lights simultaneously, bee calling organ reports to the police, thereby prevents that the door from being collided with. (the flow chart is shown in FIG. 3)
