Description

A car collision avoidance system

technical field

The utility model relates to the technical field of automobile safety monitoring, in particular to an automobile anti-collision system.

Background technique

As a means of transportation for modern humans, automobiles have brought great convenience to people's lives, but at the same time they have also brought serious traffic safety problems. Among all kinds of traffic accidents, automobile rear-end collision accidents, especially expressway automobile rear-end collision accidents are the class with the largest frequency of occurrence. Although safety protection devices such as safety belts, safety airbags and bumpers are installed in many automobiles at present, such safety protection devices can only alleviate the degree of accidents, and cannot effectively prevent accidents from happening. Car accidents happen frequently nowadays, and most of the traffic accidents are caused by the speed of the vehicle is too fast, the driving safety distance is small, and the driver is careless in driving.

Utility model content

The purpose of the utility model is to avoid the deficiencies in the prior art and provide an automobile anti-collision system capable of detecting safety distance and intelligent alarm.

The purpose of this utility model is achieved through the following technical solutions.

An automobile anti-collision system includes an alarm, a braking system, a control circuit board and a detection device for measuring distance, and the detection device, the alarm and the braking system are respectively electrically connected with the control circuit board.

Wherein, a speed sensor is also included, and the speed sensor is electrically connected with the control circuit board.

Among them, the detection device includes two rangefinders, specifically the front rangefinder and the rear rangefinder. The front rangefinder is installed at the front of the vehicle, and the rear rangefinder is installed at the rear of the vehicle. The distance meter is electrically connected with the control circuit board respectively.

Wherein, the range finder is a laser range finder.

Wherein, the range finder is an infrared range finder.

Wherein, the braking system is a dynamic braking system.

Wherein, the automobile collision avoidance system also includes an emergency light, and the emergency light is electrically connected with the control circuit board.

Beneficial effects of the utility model: an automobile anti-collision system includes a detection device for distance measurement, an alarm, a braking system and a control circuit board, and the detection device, the alarm and the braking system are respectively electrically connected to the control circuit board. The utility model measures the distance between the cars through the detection device. When the distance between the cars is less than the safe distance, the alarm sounds to remind the driver. The driver can perform emergency operations such as braking or dodging according to the current situation. When the alarm sounds or other factors fail to brake and decelerate in time within the preset time or distance, the control circuit board starts the braking system to force deceleration. Compared with the prior art, the utility model can efficiently reduce traffic accidents, and is safe and practical.

Description of drawings

Utilize accompanying drawing to further illustrate the utility model, but the content in the accompanying drawing does not constitute any restriction to the utility model.

Fig. 1 is a structural schematic diagram of Embodiment 1 of an automobile anti-collision system of the present invention.

Figure 1 includes:

1 front range finder, 2 rear range finder, 3 speed sensor, 4 control circuit board, 5 siren, 6 dynamic braking system.

Detailed ways

The utility model will be further described in conjunction with the following examples.

Example 1.

A kind of automobile anti-collision system, as shown in Figure 1, comprises speed sensor 3, siren 5, dynamic braking system 6, emergency light, control circuit board 4 and the detection device for measuring distance, this speed sensor 3, detection The device, the siren 5, the dynamic braking system 6 and the emergency light are electrically connected to the control circuit board 4 respectively. The detection device of the present embodiment includes two laser range finders, specifically a front range finder 1 and a rear range finder 2, the front range finder 1 is installed at the front of the vehicle, and the rear range finder 2 is installed at the rear of the vehicle, and The front range finder 1 and the rear range finder 2 are electrically connected to the control circuit board 4 respectively.

The speed sensor 3 of the automobile anti-collision system is used to detect the driving speed of the car and feed back the driving speed to the control circuit board 4 in the form of a signal. The distance between the front of the car, the rear of the car and the rear object, and the distance between the front and the rear of the car are fed back to the control circuit board 4 in the form of a signal, and the microprocessor on the control circuit board 4 will learn from the speed sensor 3 and detect The data signal obtained by the device is processed. When within the distance of the front distance or the rear distance of the car, the speed of a vehicle is a dangerous speed of a vehicle, and the control circuit board 4 then sends an instruction to allow the siren 5 to sound the alarm, prompting the driver to take corresponding measures. And when the speed of the vehicle is too fast, and the driver does not respond within the preset time or the preset distance, the control circuit board 4 then controls the dynamic braking system 6 to automatically brake and slow down, so as to avoid collision accidents. Simultaneously, the control circuit board 4 controls the emergency light to turn on to alert the vehicles behind.

Example 2.

The car collision avoidance system of this embodiment differs from Embodiment 1 in that the range finder of this embodiment is an infrared range finder. Other structures and principles of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model rather than limiting the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should It is understood that the technical solution of the utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solution of the utility model.
