Description

Automobile anti-collision assist device

technical field

The utility model relates to the field of automobile safety, in particular provided with an automobile anti-collision safety auxiliary device.

Background technique

In daily life, private cars have become the main way for people to travel. The increase in the number of vehicles has also increased the complexity of the road. Therefore, the current automotive industry pays special attention to the safety system of the car, especially the anti-collision device. system.

The development trend of automobile collision avoidance system will gradually develop from passive collision avoidance to reduce injuries to active collision avoidance to reduce accidents. The current passive collision avoidance mainly depends on the crashworthiness of the car body structure, restraint systems such as seat belts and other factors to reduce the injuries suffered by members after the accident occurs. The active safety system applied to the vehicle will be the main means of reducing accidents in the future. At present, various anti-collision systems have been applied to some cars, mainly including ESP (electronic stability system, which is basically popular), ACC (adaptive cruise control) system, equipped for some high-end cars), LDW (deviation warning system, mainly used for commercial vehicles, not popularized), night vision system and other electronic equipment. The assembly of these devices enables the vehicle to intelligently intervene on the vehicle or the driver to reduce the incidence of accidents. However, the cost of the above-mentioned system itself is high, and it is generally only equipped on high-end cars. At present, there is a lack of a low-cost anti-collision auxiliary device that can be popularized on low-end cars.

Description of drawings

The following is a brief description of the content expressed in each piece of drawings in the specification sheet of the utility model and the marks in the figure:

Fig. 1 is a block diagram of an automobile anti-collision auxiliary device;

The marks in the above figures are: 1. Processor; 2. Ultrasonic ranging unit; 3. Video acquisition unit; 4. Display; 5. Sound and light alarm unit.

detailed description

As shown in Figure 1, the device mainly includes a processor 1, an ultrasonic ranging unit 2, a video acquisition unit 3, a display 4 and an acousto-optic alarm unit 5, and the processor 1 may use an ARM microprocessor 1 for processing data, ultrasonic The ranging unit 2 and the video acquisition unit 3 respectively output obstacle distance signals and image information to the processor 1, and the signals processed by the processor 1 are sent to the display 4, and the display 4 displays images and obstacle distances for prompting driving surrounding conditions. Such a prompt device with a simplified structure has a lower cost and is also convenient for subsequent modification. The display 4 can be a vehicle-mounted display or a self-assembled display.

The video acquisition unit 3 includes cameras installed on both sides of the car body. At the same time, in order to improve the acquisition effect, cameras can also be installed on the front and rear ends of the vehicle. The front camera uses the image information in front of the vehicle and is also used as a driving recorder. The cameras on both sides use obliquely downward images (for example, when parking on the side to check the positional relationship between the car and the curb), which is convenient for reducing the impact of blind spots. The camera behind the vehicle is a conventional reversing image.

Ultrasonic ranging unit 2 includes ranging radars installed on both sides of the vehicle body. At the same time, in order to improve the adoption effect, ranging radars can also be installed on the front and rear ends of the vehicle. The ranging radars installed on each side of the vehicle body are at least set There are 2, generally one is installed at the front of the car body, and the other is installed at the rear of the car body, which is used to indicate whether there is an obstacle in the visual blind spot of the rearview mirror. Accuracy of collection can be improved by using multiple cameras, and the specific positions of obstacles on the display 4 can be displayed in partitions on the display 4 .

The current on-board camera (reversing image) will only be turned on automatically when the vehicle is in reverse gear, and cannot effectively assist in reversing. , autonomously control the required image information to improve the safety of reversing. And when driving, open the required image information to assist driving and improve driving safety.

The processor outputs the alarm signal to the sound and light alarm unit 5, and when danger occurs, a prompt can be given. The light alarm subunit of the sound and light alarm unit 5 is the ambient light or dome light in the car, and the sound alarm subunit is the vehicle audio, so that further Reduce equipment costs and utilize existing on-board components.

Since there are lights at the front and rear of the vehicle, in order to improve the clarity of image acquisition at night on the side of the vehicle body, the cameras located on both sides of the vehicle body are equipped with lighting sources. Processor 1 is connected with the storage unit that stores video acquisition unit 3 image information, conveniently utilizes the camera of this device to use as driving recorder, and can effectively record the image information around (four sides) of vehicle, can when accident occurs, more accurate Restore the video information of the accident scene.

The device can adopt the following control method, the ultrasonic distance measuring unit 2 continuously receives the distance data around the car and sends it to the processor 1, and monitors all information in front and on the left and right sides when driving or parking in real time, and monitors the car and surrounding vehicles in real time or The distance of the obstacle, when the obstacle or the vehicle within 1 meter is detected, the processor 1 outputs a signal to the sound and light alarm unit 5, so that it sends an alarm signal to remind the driver to pay attention to driving, and the video acquisition work starts at the same time, Provide real-time clear images on the display screen or car DVD to avoid collisions.

The existing car anti-collision system only has the image directly behind the vehicle body when reversing, but ignores the images of vehicles or obstacles on both sides of the vehicle body, which will also affect some drivers, especially novice or female drivers. The car anti-collision auxiliary device is aimed at the situation that there are vehicles or obstacles on the left and right sides in the reversing problem. The rotatable cameras on both sides of the car body can capture the surrounding dynamics in real time and give the driver an intuitive video image display. At the same time, because it is 180 The camera can be rotated at a high degree, and the rear image can be basically understood from one side during the sideways reversing process for the situation directly behind when reversing. Therefore, as long as the device is installed on the left and right sides, a safe reversing parking space can be realized. At the same time, the front camera of the device can give the driver a very intuitive real-time view of the front and surroundings when the traffic is congested or slow in traffic jams, which can maximize the safety of the car's anti-collision.

The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner, as long as various insubstantial improvements are carried out by adopting the method concept and technical solutions of the present invention, or without Improvements that directly apply the concept and technical solutions of the present invention to other occasions are within the protection scope of the present utility model.
