Specific embodiment
Specific embodiment of the present utility model is further described below in conjunction with the accompanying drawings.
A kind of car doubling auxiliary device of the utility model, including controller, the camera being connect with controller, thunder
It reaches and warning device, camera is two, be separately positioned on car both sides, for dead zone-eliminating A and blind area B, connect controller
Radar be used to obtain the obstacle position information at car rear, dead zone-eliminating C, above controller is adopted according to camera and radar
The obstacle position information control warning device collected is alarmed, and avoids crashing.The utility model can be adopted only
The blind area of vehicle side and rear just can be eliminated with two cameras and a radar, effectively finds the doubling vehicle at side, rear
, it ensure that the safety for the process of driving.
Specifically, a kind of doubling auxiliary device as shown in Figure 2, including two cameras, respectively left side camera U1,
Right side camera U2, two millimetre-wave radars, respectively left back radar U3, right back radar U4, controller U0, two alarms
Lamp, respectively left side alarm lamp U6, right side alarm lamp U7, buzzer U8, steering indicating light detection device (being not drawn into figure) and power supply.
Left side camera U1, right side camera U2 control U0, left back radar U3, right back radar U4 difference by CVBS connections respectively
Control U0 is connected by CAN bus, two alarm lamps connect controller U0 by I/O port respectively with buzzer U7, and controller U0 leads to
CAN bus connection vehicle CAN network is crossed, speed is obtained, turns to the information such as modulating signal.
Camera is respectively arranged on left and right rearview mirror, and visual angle coverage area is as shown in figure 3, camera detection range I
Width with II coverings is at 4 meters or more, it is ensured that covering left and right adjacent lane, length are at least up to full car length, it is ensured that covering vehicle
Blind area A, B at left and right sides of.
Millimetre-wave radar is installed on vehicle tail arranged on left and right sides, and electromagnetic wave coverage area is as shown in figure 3, its covering is wide
Degree is at least each 4 meters of vehicle both sides, and 30 meters of rear view of vehicle meets lane-change decision support system (DSS) laws and regulations requirement.
Camera is detected the pedestrian in detection range and vehicle, and image information is sent to controller U0 processing
It calculates, by lighting alarm lamp (flicker) driver is reminded when judging and have pedestrian or vehicle in the region.
Left side alarm lamp U5 is installed on left-hand mirror, and right side alarm lamp U6 is installed on right rear view mirror, controller according to
Alarm lamp on the obstacle position information control left-hand mirror of camera acquisition on left-hand mirror, according on right rear view mirror
Alarm lamp on the obstacle position information control right rear view mirror of camera acquisition.For example, when the camera of left side camera U1
In pedestrian or vehicle, left side alarm lamp U5 is lighted detection range I memories, as the camera detection range II of right side camera U2
In pedestrian or vehicle, right side alarm lamp U6 is lighted memory, in this way when driver intends turning or doubling, after first passing through
Visor is observed, though pedestrian or vehicle in blind area A, B, can also learn dangerous information by alarm lamp, and then it may be noted that
Observation, drives with caution, avoids accident.
If camera detection range I memories are in pedestrian or vehicle, while driver's unlocking vehicle left steering lamp, at this time not only
Light left side alarm lamp U5, while buzzer U7 makes a sound alarm, similarly, if camera detection range II memories in pedestrian or
Vehicle, while driver's unlocking vehicle right turn lamp not only light right side alarm lamp U6, while buzzer U7 makes a sound at this time
Alarm, the alarm strategy are simultaneously emitted by alarming in terms of vision and the sense of hearing two, not only ensure the validity of early warning effect, simultaneously
Audible alarm can not also be started when driver is being not desired to turning or lane change, driver is avoided to be interfered by audible alarm, from
And generate dislike.In addition, when steering indicating light detection device detects bright steering indicating light and camera or detections of radar are to Obstacle Position
During information, controller starts buzzer warning.
Left back radar U3 and right back radar U4 are detected the vehicle in its electromagnetic wave coverage area, radar data
Information is sent to controller U0 by CAN bus and carries out processing calculating, when judge the region in have vehicle when by light alarm
Lamp (flicker) reminds driver.
When, there are during vehicle, left side alarm lamp U5 is lighted, when right back thunder in the detections of radar range I of left back radar U3
There are during vehicle in up to the detections of radar range II of U4, right side alarm lamp U6 is lighted, in this way when driver intends turning or doubling
When, it first passes through rearview mirror and is observed, even if not observing the vehicle in danger zone, danger can be also learnt by alarm lamp
Dangerous information, and then it may be noted that observation, drives with caution, avoids accident.
If there are vehicle in detections of radar range I, while driver's unlocking vehicle left steering lamp, left side is not only lighted at this time
Alarm lamp U5, while buzzer U7 makes a sound alarm, if similarly there are vehicle in detections of radar range II, while driver opens
Vehicle right turn lamp is opened, the steering indicating light detection device for connecting controller detects that right turn lamp is bright, and controller not only controls at this time
Right side alarm lamp U6 is lighted, while controller buzzer U7 makes a sound alarm, is simultaneously emitted by terms of vision and the sense of hearing two
Alarm not only ensures the validity of early warning effect, while can not also start sound report when driver is being not desired to turning or lane change
It is alert, driver is avoided to be interfered by audible alarm, so as to generate dislike.
The utility model is detected front vehicle by radar, solves the problems, such as that camera detection range is insufficient.
If vehicle body both sides are also detected using radar, first radar because volume it is larger, vehicle width, currently available technology may be influenced
In temporarily without suitable radar installation method, be secondly metal material from vehicle vehicle body, there is strong interference to radar electromagnetic wave signal
And influence, technology requirement is unsatisfactory in Radar Signal Processing, vehicle body both sides pedestrian and vehicle are detected by camera,
It is not only convenient for installing, and vision signal is not influenced by body material, it is technologically simple to implement.
As other embodiment, other sound-producing devices may be used instead of the above-mentioned control of buzzer U7 connections in the utility model
Device processed, for example, loud speaker.
In addition, the utility model also proposed a kind of car, including doubling auxiliary device, doubling auxiliary device includes control
Device, the camera being connect with controller, radar and warning device, camera are two, are respectively used to be arranged on car both sides, thunder
Up to for obtaining the obstacle information at car rear, controller is used to be believed according to camera and the collected Obstacle Position of radar
Breath control warning device.Due to the utility model proposes car doubling auxiliary device introduction in the present embodiment foot
It is enough clear complete, therefore no longer car is described in detail.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model,
Any modification, equivalent replacement, improvement and so on should be included within the right of the utility model.
