Fig. 1 shows auxiliary wheel group structural schematic diagram of parking；
Fig. 2 shows auxiliary wheel group composition block diagrams of parking；
Fig. 3 shows ideal parking place schematic diagram；
Fig. 4 shows first position schematic diagram；
Fig. 5 shows non-ideal parking place schematic diagram.
Specific embodiment
With reference to the accompanying drawings, the function that the structure of this system is described in detail and is realized.
It parks auxiliary wheel group, including data acquisition portion 1, device adjustment portion 2 and control system 3, control system 3 is according to data
The working condition for the information control device adjustment portion 2 that acquisition portion 1 is collected, makes the supplementary structures such as auxiliary wheel and is adaptively adjusted,
Intact stability when being parked with improving is reduced and is parked time-consuming.
Data acquisition portion 1 includes:
Imaging sensor 11, is installed on automobile top, the acquisition for image near parking stall；
Device adjustment portion 2 includes:
Auxiliary wheel 21 supports when for parking and drives vehicle rear transverse movement；
First driving device is installed on inside auxiliary wheel 21, for driving auxiliary wheel 21 to rotate；
Elevating lever 22, for adjusting the adjustable height of auxiliary wheel 21；
Hydraulic pump 23, for driving elevating lever 22 to go up and down；
Connecting bracket 24, for connecting auxiliary wheel 21 and elevating lever 22；
Control system 3 is configured as:
The image recognition near parking stall is acquired according to imaging sensor 11 and goes out marker, and image taking sensor 11 is original
Point establishes focal length when three-dimensional system of coordinate, the mounting height of record imaging sensor 11 and the angle of depression and shooting photo, to count
Calculate distance of the vehicle with respect to marker；
It is on the central axes of parking stall when detecting vehicle body and being greater than or equal to the first value and two front wheels at a distance from the edge of parking stall,
Vehicle is in ideal parking position at this time for judgement；
Parking stall central axes: wheel is all equal along distance with parking stall left and right side, and the point for crossing wheel is made perpendicular to parking stall bottom end
Vertical line, the vertical line are called parking stall central axes；
When vehicle is in ideal parking position, control system 3 controls elevating lever 22 and falls auxiliary wheel 21, by vehicle rear top
It rises and is lifted away from ground, first driving device drives auxiliary wheel 21 to rotate, rotation vehicle tail to first position, then storage of moving backward；
First position: vehicle is in central axes and tailstock face parking stall bottom；
When detecting that automobile tail and parking stall distance from bottom are greater than second value, vehicle does not pour into vehicle also completely at this time for judgement
In position, need to continue reversing until reaching second value；If this distance is less than or equal to second value, judge vehicle completely into library
In, stop operation of parking immediately；
When vehicle two front wheels be in parking stall central axes but vehicle body at a distance from the edge of parking stall less than the first value, at this time at vehicle
In non-ideal parking position, control system 3 controls elevating lever 22 and falls auxiliary wheel 21, and vehicle rear is jacked up and is lifted away from ground, and first
Driving device drives auxiliary wheel 21 to rotate, and rotation vehicle tail to the second position carries out subsequent operation of parking；
The second position: vehicle is in central axes and headstock face parking stall bottom；
One skilled in the art would recognize that without departing substantially from the spirit and scope of the invention as generally describing,
