Description
Technical field
The present invention relates to light automatic parking technical field more particularly to a kind of efficient generation visitors cooperateed with based on field end, vehicle end
It parks planing method.
Background technique
As city vehicle increases, parking also becomes more difficult, particularly with more difficult for new hand driver.It is another
Aspect, with the progress and the accelerating rhythm of life in epoch, driver more focuses on the time efficiency of oneself, then major master
Machine factory starts to increase automatic parking function to oneself vehicle.
Automatic parking technology on the market is generally based on the sensor installed on vehicle at present, however because vehicle uploads
The function restriction of sensor itself, so that available parking stall in Vehicular intelligent detection vehicle periphery close range, vehicle stop driving into
It is travelled behind parking lot or repeatedly in parking lot as manually stopping to find suitable parking stall and stop, for many
For large parking lot, vehicle time for wasting on finding parking stall as many as quite, thus can not fundamentally save driving
The pick-up of member is parked the time.Meanwhile being detected based on vehicle self-sensor device, investigative range is not only small, and also increasing can vehicle
Cost, and it is more demanding to draw lines to parking stall.And be only limitted to park, it cannot pick up the car, can not fundamentally solve difficulty of picking up the car of parking,
The technical issues of low efficiency.It is also favorably used in parking lot in the prior art and installs sensor, then using server by sensing
Device obtains detection information to realize although the technology for carrying out parking path planning to vehicle, this technology overcome vehicle entrance and stop
The problem of parking stall is blindly looked for behind parking lot, but the vehicle for travelling according to planning path encounters the situation of burst on path
When, such as mobile barrier etc. is encountered, vehicle needs to return to the signal for encountering obstacle to server, is then thought highly of again by service
New planning path, this process need the more time, are not able to satisfy saving driver equally and take the problem of parking the time.

The high efficiency of automatic parking.
Further advantage, target and feature of the invention will be partially reflected by the following instructions, and part will also be by this
The research and practice of invention and be understood by the person skilled in the art.
Specific embodiment
It elaborates below to the present invention, to enable those of ordinary skill in the art refering to can be real accordingly after this specification
It applies.
A kind of efficient valet parking planing method cooperateed with based on field end, vehicle end, comprising the following steps: S1, the service of field end
Device receives after the request of parking of parking vehicles, plans parking path to parking vehicles to be described, and by the parking path
It is sent to vehicle end server.
S2, the vehicle end server control control system driving vehicle to parking vehicles are according to the parking path row
It sails.
S3, vehicle end server are described on the subsequent parking path of real-time judge in parking vehicles' driving process
Whether road conditions are suitable for traveling;It is accurate driving path then to be planned on the parking path, and control described to parking vehicles
Control system driving vehicle continues to travel according to the accurate driving path;It is no, then it is advised again to the request of field end server
Draw path.
S4, field end server are after receiving the request of planning path again of vehicle end server transmission, to be described wait moor
Vehicle vehicle plans parking path again, and is sent to vehicle end server.
S5, S2-S3 is repeated, until described travel to parking vehicles to the terminal of the parking path of planning.
In the above scheme, after receiving and parking instruction, field end server by utilizing itself is to field end road and parking stall
The understanding of real-time condition can be vehicle Rapid matching parking stall, and be vehicle planning parking road according to parking stall and the position of vehicle
Diameter, and the road conditions on vehicle end server real-time detection driving path in the process of moving, can be according to road conditions for driving path
Carry out fine planning, thus when vehicle encounters barrier or road is relatively narrow, can real-time judge vehicle whether
Can safety, that is, realize macroscopical path planning and local path and adjust the automatic parking mode combined, thus effectively
Avoid because of emergency situations caused by vehicle collide with, effectively raise the efficiency of automatic parking.
In one preferred embodiment, the server of field end described in S1 is described to parking vehicles' rule according to the real-time condition at field end
Draw parking path.
In the above scheme, field end server is to plan parking path to parking vehicles according to the real-time condition at field end, is made
It obtains parking path and adapts to real-time road, i.e., so that parking path is more accurate, feasibility is higher.
In one preferred embodiment, the real-time condition at the field end includes the road conditions and parking stall situation at end;It is described
The road conditions and parking stall situation at field end are obtained using the field end sensor for being set to the field end.
In the above scheme, field end server is according to the real-time road conditions in field end and parking stall situation to the road of parking of vehicle
Diameter is planned, enables to the parking path of planning more efficient.
In one preferred embodiment, the server of vehicle end described in S3 judges whether the road conditions on the subsequent parking path fit
The standard preferably travelled includes: width, barrier, traffic density and the road flatness of road.
In the above scheme, the vehicle difference of vehicle causes the of different sizes of vehicle, road of the field end server for vehicle
Diameter planning does not consider the of different sizes of the vehicle of a variety of models only for vehicle, thus vehicle end server judges subsequent pool
Whether the road conditions of bus or train route diameter are suitable for the width for when driving including road, to be not enough to when vehicle width is larger by current
When road, can inform an end server be the new planning path of the car weight, equally, vehicle driving arrive certain position when, possibility
Occur movable barrier occur or other vehicles also drive to the position on path so that the traveling of vehicle by
Limitation, furthermore road flatness is too low, vehicle lower for chassis is also easily detected by, thus after the judgement of vehicle end server
