Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not considered as limiting the invention.
The control of the DAS (Driver Assistant System), DAS (Driver Assistant System) of vehicle according to embodiments of the present invention is described below in conjunction with accompanying drawing
Method processed and vehicle.
Fig. 1 is the structured flowchart of the DAS (Driver Assistant System) of vehicle according to an embodiment of the invention.As shown in figure 1, root
According to the DAS (Driver Assistant System) 100 of the vehicle of one embodiment of the invention, including:Camera assembly 110, detection module 120 and control
Device 130.
Wherein, camera assembly 110 can move up and down and left rotation and right rotation be arranged on vehicle body, schemed with gathering around vehicle body
Picture.Detection module 120 is used to detect body information and vehicle body ambient condition information.Controller 130 be used for according to body information and/
Or vehicle body ambient condition information control camera assembly moves up and down accordingly and/or left rotation and right rotation.Such as:According to body information and/
Or vehicle body ambient condition information determines the optimal acquisition region of image around vehicle body first, and according to around vehicle body image it is optimal
Pickup area control camera assembly moves up and down accordingly and/or left rotation and right rotation.
As shown in Fig. 2 camera assembly 110 can move up and down and left rotation and right rotation be arranged on the rear portion of vehicle body.Generally collection
Vehicle body rear or the image of rear ramp.Camera assembly 110 may include:Camera and actuator, wherein, camera collection vehicle body
Surrounding image.Actuator is connected with camera, and to drive camera to move up and down, actuator is controlled by controller 130.I.e.:Control
Device 130 processed can by actuator drive camera move up and down, so, camera can to move up and down, wherein, actuator bag
Include but be not limited to small-sized motor.
In one embodiment of the invention, camera is rotary pick-up head.So, controller 130 can drive shooting
Head left rotation and right rotation.Certainly, in the other examples of the present invention, camera left-right rotary can also be driven by the rotating mechanism of setting
Turn.
In the DAS (Driver Assistant System) of the vehicle of the embodiment of the present invention, detection module 120 is for example including range sensor, distance
Sensor is used to detect height of the vehicle body away from ground, and controller 130 is used for when height of the vehicle body away from ground changes, according to
Height change situation control camera assembly of the vehicle body away from ground moves up and down accordingly.
It should be noted that height of the vehicle body away from ground refers on vehicle body some target point to the distance on ground, the target
Point can be chassis, i.e., chassis is apart from ground.
As a specific example, with reference to shown in Fig. 2, it is assumed that the scope that camera is monitored under normal condition is away from ground
Height below 80 centimetres of face, the amount of movement of the height in the vertical direction of vehicle are 0~-30 millimeters, wherein, straight down for
It is negative, straight up for just, 0 refers to the amount of movement under vehicle no-load condition, for a certain truck, increase weight one on car
Ton, about -8 millimeters of overall height increase, vehicle at most can 5 tons of load-bearing.When the goods on car increases to 2 ton hours, the height of truck is big
About increase -15 millimeters.Now, the height of car change information that range sensor senses, can will be current by CAN
Bodywork height is sent to controller 130, and controller 130 highly obtains according to current bodywork height and vehicle no-load condition under body
15 millimeters are have dropped to difference in height, such as bodywork height, then controls height of the camera from vehicle without the state of goods to ramp up
It is higher, 12 millimeters are such as ramped up, so as to ensure that the scope that camera is detected remains regarding for early substantially sustained height
It is wild.Also, the image that now camera gathers can also be sent on the display terminal of in-car by controller 130 in real time, such as
Middle control display screen, the picture for ensureing to occur on display screen remain as the optimal detection angle of camera (i.e.:Image is most around body
The image of good pickup area, such as the blind area after car), so, no matter how much truck freights, and driver can be clear by display screen
Blind area situation after car is recognized clearly, lifts vehicle safety.
In addition, body information can not only include vehicle body the height away from ground, direction information, such as steering wheel can also be included
Corner etc., the DAS (Driver Assistant System) of the embodiment of the present invention, controller 130 can also control camera assembly 110 according to direction information
Corresponding left rotation and right rotation.Such as:Vehicle beats to the right wheel, therefore driver, can control shooting it should be understood that vehicle right side situation
Component 110, so as to the image of (such as right back) on the right side of collection vehicle, refers to right rotation for driver.
Wherein, camera assembly 110 may be provided at vehicle body rear, so, during left rotation and right rotation, can collect vehicle left back
Or the image of right back.
In another example of the present invention, detection module 120 may also include acquiring unit, and acquiring unit is used to obtain vehicle body
Ambient condition information, controller 130 determine to whether there is obstacle around vehicle body according to vehicle body ambient condition information, and it is determined that car
When obstacle around body be present, 110 corresponding left rotation and right rotation of camera assembly is controlled, so that driver gathers according to camera assembly 110
Image obstacle avoidance around the vehicle body arrived.
Specifically, such as:Controller 130 controls camera assembly 110 to dextrorotation when it is determined that obstacle be present on the left of vehicle body
Turn, so that driver is according to vehicle body image right obstacle avoidance, when it is determined that obstacle be present on the right side of vehicle body, control camera assembly
110 to anticlockwise, so as to driver's vehicle body left-side images obstacle avoidance.
As a specific example, when vehicle is during advance, if vehicle body left field is larger, but on the right side of vehicle body
There are barrier, such as fence, road tooth, camera detects traveling ambient state (i.e. by rotating first:Vehicle body surrounding environment is believed
Breath), after acquiring unit is got, controller 130 is sent to by CAN, controller 130 can pass through some image recognitions
Technology, which is identified on the right side of automobile body, barrier, just controls the monitoring direction of camera mainly to monitor on the left of vehicle body, makes driving
Member recognizes the situation on the left of vehicle body, so as to draw close to the left to evade the obstacle on right side, helps driver preferably to plan
Driving path.Lift traffic safety.
The DAS (Driver Assistant System) of vehicle according to embodiments of the present invention, it can be moved up and down and left rotation and right rotation in vehicle body dress installation
Camera assembly, the image pickup scope of camera assembly can be adjusted in real time according to body information and vehicle body ambient condition information, protected
Card camera assembly has optimal shooting angle, and the dynamically present image of display such as vehicle rear-side, and then, can be effectively
Auxiliary driver judges the situation around vehicle body, assists driver to be judged and planned, after prompting driver such as vehicle in time
Side and surrounding reduce the possibility that accident occurs, lift traffic safety with the presence or absence of danger.
