Description
Technical field
Present invention relates generally to City Rail Transit System field, refers in particular to a kind of track suitable for virtual rail train
Following control system.
Background technology
City Rail Transit System is the special line public transportation system for having continuous steerable ability, and its feature shows as possessing
Whole piece dedicated track, and row can not be mixed with motor vehicle.(for example no crossroad, its road foundation construction do not set people's row horizontal stroke
Road, the special road of no bicycle and without motor vehicle circuit).Normal conditions, City Rail Transit System are mostly built in underground or height
On bridge formation.Its free-running operation in track special line is realized by using inaccessible pattern.City Rail Transit System can also
Use full-automatic operational mode.In addition, City Rail Transit System is divided into heavy and light-duty two kinds, such as subway and light again
Rail.But the obvious infrastructure construction input of this form is larger.
Modern City Traffic system main composition is subway, tramcar, bus etc., although subway transport capacity is powerful,
But its cost is huge so that it can not extensive use in small and medium-sized cities;Tramcar needs special power system and track to match somebody with somebody
Design is closed, either design and construction cost or maintenance cost are relatively large and are easily limited by running environment;
Traditional bus cost is lower, and very flexible relative to railroad vehicle, can be very square when there is barrier in front
Just barrier of avoiding continues to travel, and when vehicle breaks down, can keep to the side, and does not interfere with other vehicles traveling.But tradition
Bus transport power is few, it will usually increases transport power by be hinged more piece compartment come formed automobile train.Develop vapour in small and medium-sized cities
Car team car substitutes traditional bus, and under the conditions of ensureing truck combination by safety factors such as property and steering behaviours, it is not only
Transport capacity can be improved and cost of transportation 30% or so can be reduced.Although articulated road train car passenger carrying capacity is big,
It is that it is compared with monomer car, maximum difference is the change by property because of the road that length of wagon longthening belt comes, and shows as turning
Curved radius increase, track area shared by turning increase, and easily the other elements of road traffic with side interfere, so that can not be suitable
Profit by, or even deteriorate traffic circulation environment, can not fast and efficiently realize public transportation.
Four-wheel steering technology especially rear-axle steering technology occurs to realize that the all-wheel steering function of automobile provides technology branch
Hold.At present, all-wheel steering technology has obtained ripe application in some vehicles, such as new 7 system of BMW, produces elegant 350GT daily
Etc. vehicle, also it is widely used in the special vehicle such as beach buggy in addition.The further investigation of linear control system is simultaneously applied to certain
A little vehicles, such as BMW " Z22 concept cars ", Toyota Company " Lexus HPX " etc., it is domestic at present for four-wheel steering and linear to turn
Research to control system is also increasingly subject to pay attention to.By using line traffic control holoaxial steering technique, the car of truck combination can be caused
It is controllable to take turns track, can significantly increase the passing through property of truck combination.
But how using line traffic control multi-axle steering technology to realize that the wheel trajectories of rubber tire train are controllable, even ensure to advance
The track coincidence factor of direction wheel, it is necessary to invent a kind of track following control system be used for using line traffic control holoaxial steering automobile
The steering of wheel is controlled on train, to increase the track coincidence factor of rear wheel and front-wheel in direction of advance, reduces and turns to " lubrication groove
Difference ", reduce the influence that " visual dead angles " are brought.

Comprising)The coordinate information of truck combination first segment vehicle centroid is obtained by the Multi-sensor Fusion such as Kalman filtering algorithm
(For origin before being started with truck combination, truck combination first segment automobile body direction is X-axis, and vertical vehicle body is Y direction).Car
Head rail mark following controller 1 passes through feedforward control and feedback closed loop control by calculating the coordinate data at the second steeraxle center
System obtains the steering angle of the second steeraxle, then is turned to by the driving moment of steer by wire apparatus 108 and remove the second steeraxle to correct
The lateral displacement relative to the first steeraxle track, so as to realize control targe that the second track shaft follows, while second turn
The track model- following control on next section compartment is transferred to by way of CAN communication or other high speed communications to the coordinate data of bridge
Device.
When all wheels travels of vehicle are in identical track, lubrication groove difference is zero, and the rubber tire train can be with the side of track traffic
Formula is oriented to traveling, travels in fixed route, the vehicle in other tracks, pedestrian will not be interfered.
In the present embodiment, compartment track following controller 2 receives upper one by way of CAN communication or other high speed communications
The coordinate data of axle, the data gathered in conjunction with all angles sensor on this section compartment and wheel speed sensors and and first segment
The splice angle of compartment junction, the coordinate of axletree on the section compartment is extrapolated, then obtained by feedforward control and feedback closed loop control
The steering angle of axletree on the section compartment must be removed, is turned to by steer by wire apparatus driving moment and removes axletree on the section compartment to correct
The lateral displacement relative to previous axletree track, so as to realize control targe that track follows.Tailstock track model- following control
The working method of device 3 is as compartment track following controller 2.
From the foregoing, it will be observed that the rubber tire train track following control system of the present invention, using scattered control for permutation vehicle
The thinking of system, sampled data and the steering controller and model- following control of single-unit vehicle can follow control in the unit of the section vehicle
Device processed realizes that unit following controller directly sends steering order to steering controller.The coordinate trajectory data of vehicle passes through
The mode of CAN or the mode of other high speed communications realize the transmission between previous section vehicle and later section vehicle.
I.e.:Headstock track following controller 1 is by gathering steering wheel angle, the steering angle of each vehicle bridge, each wheel
Information that wheel speed and guider provide obtains the coordinate at headstock units centre of mass;Compartment track following controller 2 and car
Tail track following controller 3 is acquired simultaneously to the sensor in the compartment and with the splice angle on the pin joint of front truck hinged place
The running orbit of this section compartment axletree is controlled by the coordinate data in the upper section compartment of communication network transmission reception again.This control
Each sensor data acquisition and sensor fusion algorithm are dispersed in the following controller of each vehicle unit track by mode processed
To realize, the structure of track following control system can be greatly simplified, while also allows for the modular arrangements of vehicle, such as needs to increase
The joint number of vehicle, vehicle unit track following controller need to be only connected in CAN or in other high speed communication buses.
The above is only the preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-described embodiment,
All technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art
For those of ordinary skill, some improvements and modifications without departing from the principles of the present invention, the protection of the present invention should be regarded as
Scope.
