Fig. 1 is a schematic block diagram of the principle of the utility model automobile active safety anti-collision warning system.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the structural principle of the present utility model will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

As shown in Figure 1, a kind of automobile active safety anti-collision early warning system, comprises lane line detection unit, vehicle speed detection unit, turn signal detection unit, head-up display unit and the control unit that is used to control each functional unit to coordinate work, described The lane line detection unit, vehicle speed detection unit, direction light detection unit, and head-up display unit are respectively connected to the control unit, the lane line detection unit is connected to the image acquisition unit, and the head-up display unit is connected to the voice prompt unit.

The image acquisition unit described in the utility model includes a plurality of cameras installed on the windshield in the vehicle to collect image information of road conditions ahead of the vehicle. The lane line detection unit includes an image comparison processor. The vehicle speed detection unit includes a GPS module. The direction light detection unit includes a comparator connected with the direction light and capable of judging whether the direction light is triggered, and the output terminal of the comparator is connected with the control unit. The control unit includes a central processor for judging and analyzing the image information processed by the image comparison processor and checking whether the lane lines and vehicle speed are within the allowable range. The head-up display unit includes a head-up digital display (HUD) for displaying the information sent by the control unit on the front windshield of the car according to different presets. The head-up display unit also includes an automatic photoreceptor that can automatically adjust the brightness of the head-up display according to light changes outside the vehicle. The voice prompt unit includes a loudspeaker capable of realizing male voice or female voice or single ring tone and English alarm prompt. The above-mentioned components or instruments can adopt existing mature components or instruments. The utility model is not a simple combination of existing components or instruments. The utility model uses existing mature components or instruments through efforts to solve the phenomenon of driving deviation, drowsiness, and unconscious driving. It is an active safety anti-collision warning measure for automobiles that detects and makes an alarm in time.

The lane departure warning function provided by the utility model is aimed at situations such as negligence, lack of concentration, drowsiness, fatigue, etc. that often occur when the driver is driving the vehicle. At this time, the vehicle is easy to deviate from the normal lane. At this time, if the rear vehicle does not take appropriate avoidance measures, the two vehicles are prone to side collision accidents, or even rollover and hit the guardrail. The lane departure warning function uses high-tech visual radar to accurately detect road markings. When the vehicle unintentionally deviates from the lane, it will give an alarm 0.5-1 second in advance to reserve enough time for the driver to react and take corresponding measures to keep driving in the normal lane. .

Especially on the expressway, monotonous, long-term driving is prone to negligence and fatigue, resulting in lane departure, which is also the main reason for the frequent occurrence of expressway accidents. For long-distance driving and beginners on the road, the lane departure warning function can be used to increase driving safety.

When the vehicle enters and exits the tunnel and the eye pupil light source is not adjusted properly, the lane departure warning function still monitors the road surface and the traffic conditions ahead in real time, and if there is a threat, it will issue a warning in time to remind the driver to take measures.

The utility model can also realize the function of alarming when overspeeding. It obtains the vehicle speed signal through GPS, and alarms when the vehicle is overspeeding, so as to avoid overspeeding danger and a large number of overspeeding electronic fines.

The HUD head-up display function of the utility model is the first to apply the HUD head-up centralized display system used on fighter jets to the automobile technology. The driving information is displayed on the front windshield, and the driver can see the driving information such as vehicle speed, lane departure, overspeed, and battery at a glance without looking down while observing the lane and road conditions ahead. It avoids the visual contradiction of looking down at the instrument panel for 1-1.5 seconds and alternately observing inside and outside, effectively avoiding the occurrence of potential danger at this time.

The utility model can also realize the vehicle distance monitoring function, timely monitor the vehicle distance in front of the car, and when the relative distance is less than 0.6 seconds, the audible and visual alarm reminds the driver to keep a safe distance between vehicles. The utility model can also realize the collision warning function, and when the collision danger can be accurately judged, an alarm can be sent to the driver 2.5 seconds in advance.

The utility model can also realize the rear-end collision warning function. Once it is judged that there is a collision risk ahead, the rear brake light will automatically flash in advance to remind the driver behind to keep a safe distance between vehicles, thereby effectively avoiding serial rear-end collision accidents.

The working principle of the utility model: through the camera installed on the windshield inside the car, collect and analyze the roadway route, when the vehicle deviates from the lane (unconsciously: do not turn on the turn signal), the system sends out an alarm 0.5-1 second in advance , assist the driver to correct the direction, and actively avoid traffic accidents such as side collisions and rollovers.

The above content is only a preferred embodiment of the present utility model, and is not intended to limit the implementation of the present utility model. Appropriate modifications or modifications made by those skilled in the art according to the concept of the present utility model are included in the scope of the present utility model. within the scope of protection.
