Description
Technical field
The utility model relates to vehicular field, especially relates to a kind of vehicle lane change ancillary system.
Background technology
Along with popularizing of automobile consumption, the requirement of people to automotive safety is more and more higher, and nonstandard driving behavior is the one of the main reasons causing having an accident.Wherein, not playing steering indicating light before lane change is the major cause causing car accident in the same way.Simultaneously, existing lane change ancillary system can be passed through sensor (as radar, ultrasonic etc.) and detect target in vehicle blind zone, thus after chaufeur passes through to beat steering indicating light apprizing system lane change intention, the unsafe lane change behavior of chaufeur can be reminded by alarm forms such as sound.But the prerequisite that current lane change ancillary system effectively works is that system is intended to by the lane change of steering indicating light signal acquisition chaufeur.If chaufeur causes not opening steering indicating light during lane change due to nonstandard driving behavior (as lane change does not play lamp) or other any reason, then current lane change ancillary system cannot know the lane change intention of chaufeur effectively, thus can not provide alerting signal for dangerous lane change behavior in time.
Forward-looking vision system is installed on various vehicle widely as a kind of active safety product at present, realize deviation warning by image procossing, frontal collisions early warning, track keep auxiliary etc., however system not relevant at present using forward-looking vision system as a module integration in other system of vehicle.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and the vehicle lane change ancillary system that a kind of drive safety is high, lane change reliability is high, compatible extensions is strong is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of vehicle lane change ancillary system, in order to auxiliary vehicle safety lane change in the process of moving, comprise vehicle-mounted lane change accessory equipment, described vehicle-mounted lane change accessory equipment comprises the trailer-mounted radar, vehicle-mounted ECU and the warning display device that connect successively, this system also comprises vehicle-mounted forward looking device, described vehicle-mounted forward looking device comprises the forward sight camera, A/D converter, Video Decoder and the signal processor that connect successively, described forward sight camera is arranged on automotive front end, and described signal processor is connected with vehicle-mounted ECU by automobile bus.
Described forward sight camera can be the camera of any type, comprises fine resolution full-view camera.
Described A/D converter is AD8112 Video Quality Metric matrix.
Described signal processor is dsp processor, arm processor or Embedded PC treater, and Built-in Image recognizer module.
Described warning display device comprises Vehicular display device, vehicle carried lamp and vehicle-mounted buzzer phone, and described Vehicular display device, vehicle carried lamp are connected with vehicle-mounted ECU respectively with vehicle-mounted buzzer phone.
Described automobile bus is CAN, Lin bus or MOST bus.
Described vehicle-mounted ECU is provided with onboard sensor expansion interface.
When automobile lane change, the lane mark video image in track, forward sight camera Real-time Obtaining automobile place, and the lane mark video image of acquisition is delivered in signal processor by the conversion of A/D converter and Video Decoder and decoding, signal processor is by judging that lane mark video image information determines vehicle whether lane change, then lane change information is sent to vehicle-mounted ECU, vehicle-mounted ECU is judged by the signal of trailer-mounted radar that gets and lane change informix, and is undertaken showing and reporting to the police by warning display device.
Compared with prior art, the utility model has the following advantages:
One, drive safety is high: the utility model can carry out lane change by video monitoring vehicle, and automatically identifies lane change behavior thus provide alerting signal, thus the accident that prevention is not opened steering indicating light and system work not yet in effect due to chaufeur and caused
Two, lane change reliability is high: the utility model can carry out lane change during in track, when chaufeur does not open steering indicating light, still normally effectively can work by video identification, thus reduces the operation requirements of system for chaufeur.
Three, compatible extensions is strong: vehicle-mounted ECU of the present utility model is provided with onboard sensor expansion interface, changes control signal a little and can apply the utility model and follow and integrate mutually based on dissimilar lane change ancillary systems such as radar, ultrasonic and light sensations.
