The utility model discloses a to ADAS function expand, lane departure warning, preceding to collision early warning, pedestrian's protection has been realized simultaneously to intelligent rear miscellaneous function has been increased, initiative safety precaution when having realized backing a car.
Description
Technical field
This utility model relates to onboard safety systems, is specifically related to the ADAS system of the integrated rear portion active safety early warning of a kind of view-based access control model.
Background technology
After entering 21 century, socio-economic development is rapid, and urbanization process is very fast, and domestic automobile owning amount steeply rises.Along with increasing sharply of China's vehicle guaranteeding organic quantity, vehicle accident quantity also increases as.As a kind of important active safety system, ADAS(advanced person's drive assist system of view-based access control model) there is the features such as low cost, accuracy height, visualization, the ADAS of view-based access control model applies more and more extensive in field of automobile safety, it has also become one of electronic equipment indispensable in automobile safety system.The most in recent years, along with people's reinforcement to motor-vehicle accident control consciousness, in the unit of operation of many passenger vehicles, car steering aid system has obtained emphasis application, and serves the effect of well prevention major accident generation.At present, on market, the ADAS product of existing view-based access control model mainly has following two feature: 1, being an independent electronic equipment, the most other electronic product with automobile is not linked up, and needs to gather the speed of car load, windscreen wiper state, the hard signal such as turn to；Need to install independent information process unit alarm unit and display unit additional；2, function is just for the application of front video and function singleness (such as only deviation alarm, frontal collisions early warning).
In a word, independent ADAS not only function singleness, and need to increase overall wire sheaves, the equipment installed additional is many, and install with vehicle has inconvenience more, with current vehicle electronics information sharing and function fusion, it is to avoid design iterations causes the theory of the wasting of resources incompatible with.
Utility model content
ADAS function, in order to solve the problems referred to above, is extended by this utility model, can realize lane departur warning, forward direction anti-collision warning, pedestrian protecting simultaneously, and add intelligence rear miscellaneous function, it is achieved that active safety early warning during reversing.
The technical solution adopted in the utility model is: the ADAS system of the integrated rear portion active safety early warning of a kind of view-based access control model, including ADAS controller, rearview camera, forward sight photographic head, supervise display, DVR system and instrument system and alarm unit, described ADAS controller is connected with rearview camera, forward sight photographic head and the prison display that falls respectively by CVBS interface, ADAS controller connects DVR system and instrument system and alarm unit by car load CAN network, and front raw video signal is sent to DVR system by CVBS interface by ADAS controller simultaneously.
This utility model uses and provides the benefit that: ADAS function is extended by the present invention, can realize lane departur warning, forward direction anti-collision warning, pedestrian protecting simultaneously, and add intelligence rear miscellaneous function, it is achieved that active safety early warning during reversing；Network facet, accesses car load CAN network, by Network Capture speed, turn to, move backward, windscreen wiper lamp switch amount information, simplified overall wire sheaves；By ADAS warning message by being sent in car load CAN network, instrument parse alarm condition, control voice module and LCD carries out sound and image alarm；Video image after matching can be exported to supervising display, the video at vivider statement rear by intelligence rear auxiliary；Front original video interface is provided, can record a video to DVR system.
Accompanying drawing explanation
Fig. 1 is system construction drawing of the present utility model.
Detailed description of the invention
As shown in Figure 1, this utility model is the ADAS system of the integrated rear portion active safety early warning of a kind of view-based access control model, by transmission of video information at car load CAN network, the video information collected by vehicle is separately sent in ADAS controller 5, instrument system and alarm unit 4 and DVR system 6.Video collect device used in this utility model includes rearview camera 1, forward sight photographic head 2 and the prison display 3 that falls; video information is saved as the file of CVBS form by above-mentioned photographic head; and send the file in ADAS controller 5; shown by prison display 3 after ADAS controller 5 processes; in order to complete such as lane departur warning, forward direction anti-collision warning, pedestrian protecting and intelligence rear auxiliary control system implementation strategy, the original video information that photographic head shoots can be stored in DVR system by ADAS controller simultaneously.
The picture signal that lane departur warning (LDW) transmits with forward sight photographic head 2 is input, with software algorithm capture, the lane line that identifies on road, and according to body width in nominal data, it is judged that whether two sidecar wheels delay unloading diatom.When two sidecar wheels roll lane line, algorithm is identified by calculating and decides whether, according to the steering indicating light information obtained from car load CAN, the information of giving a warning.If steering indicating light is not switched on, ADAS controller sends warning message, instrument control voice module and LCD screen, and prompting driver's travel direction deviates.If steering indicating light is opened, even if identifying vehicle line ball situation, also will not alert.
The picture signal that forward direction anti-collision warning (FCW) transmits with forward sight photographic head 2 is for input, captured, identify the existence of front vehicles by software algorithm, by estimating the movement locus from car, relative with front truck with car's location and relative velocity, when there being risk of collision, give a warning to driver.Obtain from car load CAN from car speed, with the relative speed of front truck with picture signal for input, use software algorithm to obtain.FCW reminds driver avoid rear-end impact or reduce crash severity by giving a warning.System should give a warning in time and help driver to avoid most of common rear-end impact in the way of applying brake force.Warning should select suitably opportunity, is allowed to can not result in again interference or false alarm enough in time with collision free.In work process, FCW only provides warning, does not carry out wagon control.
The picture signal that pedestrian protecting (PP) transmits with forward sight photographic head 2 is for input; calculate in real time the time (TTC) that pedestrian and car in front side will collide; when TTC is once reduced to a dangerous values when, before system can produce warning at once.Pedestrian protecting typically requires that the pedestrian jaywalked suddenly, when travel speed is slower, is identified, and gives a warning by vehicle, reminds driver mainly to dodge.
Intelligence rear aid system (MOD) is during reversing, it is possible to auxiliary driver drive.Remind driver to avoid and the barrier collision from car rear by giving a warning.Warning should select suitably opportunity, be allowed to can either collision free in time, do not result in again interference and false alarm.In work process, MOD only provides warning, does not carry out wagon control.
Claims (1)
1. the ADAS system of the integrated rear portion active safety early warning of a view-based access control model, including ADAS controller, rearview camera, forward sight photographic head, supervise display, DVR system and instrument system and alarm unit, it is characterized in that: described ADAS controller is connected with rearview camera, forward sight photographic head and the prison display that falls respectively by CVBS interface, ADAS controller connects DVR system and instrument system and alarm unit by car load CAN network, and front raw video signal is sent to DVR system by CVBS interface by ADAS controller simultaneously.
