Specific embodiment
In the accompanying drawings, same or similar element is indicated using same or similar label or there is same or like function
Element.The embodiment of the present invention is described in detail with reference to the accompanying drawing.
Present invention machine to be utilized imitates three kinds of traffic objects, and the complex road condition being likely to occur is restored in real roads,
Test reply of the intelligent vehicle under complex environment.As Figure 1-1, intelligent network provided by the present embodiment joins the omnipotent test of vehicle
Platform includes tested vechicle 10, traffic object simulator, Communication topology and motion control unit.It below will be to each portion
Divide and carries out expansion explanation.
Tested vechicle 10 is disposed in traffic scene, and the traffic scene is built by multiple sliceable units, is passed through
Traffic scene is used to restore the environment of real roads as test site.As shown in Figure 1-3, A and B are that shape is each in Fig. 1-3
Different sliceable unit, A indicate ordinary road, and B indicates crossing roadside.Building for traffic scene is intended to restore true road conditions ring
Border is taken the thought for being similar to happy high building blocks that all traffic scene discretizations are become sliceable module, is tested in this way
What the scene of demand is, which type of scene the present embodiment can build, and module recycling substantially reduces test
Field occupied area, has saved resource.These traffic scenes can be abstracted into the combination of some individual modules: common roadside, crossing
Roadside and traffic lights.The present embodiment carries out unit using EPE pearl wool plate, PP rigid plastic sheets and rubber road shoulder
Production.
Test carriage control method provided in this embodiment for intelligent network connection vehicle test by motion profile dimension and
Consciousness reacts two dimensions of dimension to simulate the behavior pattern of traffic object model.
According to the classification in road traffic, the participation object in real traffic can substantially be divided into: motor vehicle, non-maneuver
Vehicle, row humans and animals (such as: cat, dog etc.), in consideration of it, the population of traffic object to be simulated is divided into 6 classes: people by the present embodiment
Class, non-motor vehicle, pet, poultry and livestock.Below with reference to the kind heap sort of traffic object, to the simulation of motion profile dimension and
The principle of consciousness reaction dimension simulation is described in detail.
(1) about motion profile dimension
The emulation of motion profile dimension includes speed, route and period.Those of ordinary skill in the art are knowable: no matter
Which kind of population, movement is all not simple uniform motion, is periodically moved, and the period depends on the movement of population
Feature.Such as: for pedestrian, the movement of arm constitutes a period of motion；For dog, movement can by the period
To be defined as the time that two half soles contact to earth.That is, the difference of population essentially consists in the length in period, the sequence of movement
And course bearing in the period etc..According to the pertinent literature of many bionics and traffic behavior, a series of populations have been taken out
Motion profile and rate profile.The data of certain populations are inconvenient to acquire, therefore current embodiment require that using real-time people
Class or the sampled data of animal.
Simultaneously, it is clear that different populations has different speed, can be according to mood, age, body same population
Situations such as situation, switches different movement rates.The present embodiment stresses the classification of mood, and " mood " refers mainly to fast in the period
The variation of rate.Under study for action, mood is divided into three classes: sluggish (slow), average (normal) and restive (active),
Respectively correspond low rate, medium-rate and high-speed.By two dimensions of population and mood, the present invention can preferably will be any
One traffic object model corresponds in corresponding characteristic.For example, corresponding with old man is (people, slowly), it is corresponding with young man
Be (people, active), corresponding with wildcat is (pet, active), and corresponding with common dog is (pet, normal).
(2) emulation about consciousness reaction dimension
In view of the consciousness of traffic object, they should can make corresponding reaction when by extrinsic motivated.It is different
Object reaction it is different.For going across the road, when certain object cross street meet with laterally carry out vehicle when, have following three kinds of tables
It is existing: 1) to accelerate to pass through, and with slight turning；2) it stops until vehicle passes through；3) it steps back to guarantee safety.It is sent out by investigation
2) and reaction 3) existing: the mankind are more likely to make, and pet tends to accelerate to pass through.
It should be noted that reaction is not a definite event, it is a probability distribution on the contrary, therefore realize
Difference is not reflected in reply itself, but divides the difference less than the probability in various actions.It, may 80 people in 100 people
It can select to wait vehicles mistake, vehicle mistake is robbed in 20 personal choices；And in 100 cats, 20 selections wait vehicles mistake, and vehicle mistake is robbed in 80 selections.For
One people of monomer and a cat, it is possible to they can make same reaction in outer plus stimulation, but when test sample tends to
When infinite, otherness will show obvious.
In terms of code, the present invention also describes the difference of this consciousness dimension using probability.Point from population to population
Cloth difference is very big, is slightly different from mood to mood.Logical object model judgement is built for single, the present invention generates one at random
Number adjusts the threshold value of judgement to judge to change different reaction patterns.For entire complete series of acts, the present invention makes
It is realized with decision tree, and program is by continuous service, until outside stimulus disappears.
In view of above-mentioned principle, as shown in Fig. 4-1, the test carriage control provided in this embodiment for intelligent network connection vehicle test
Method includes:
Step 1, traffic scene is preset.Wherein: traffic scene such as can be the people's vehicle that goes across the road cross, people's vehicle of overtaking other vehicles in the same direction
It crosses, turn to people's vehicle and the traffic scenes such as cross.
Step 2, the traffic scene preset according to the step 1 determines required traffic object model and its institute
The population of category and mood.
Step 3, the traffic object model and its affiliated population and mood determined according to the step 2, generates
The traffic object model is in the behavior pattern in the traffic scene.
The behavior pattern is divided into normal mode and incentive mode.
Under the normal mode, the traffic object model have conventional consciousness in the default traffic scene and with
The routine realizes the behavior pattern to match；Under the incentive mode, the traffic object model is in the default traffic scene
In by the reaction made after external drive be divided into the first reaction, second reaction and third reaction, it is described first reaction probability
Pi1, second reaction probability P i2 and third reaction probability P i3's and for 1, i by the external drive and the default friendship
The population of logical scene determines.
If the behavior pattern is the incentive mode, a random number range, the traffic object model are also generated
It will be moved according to the matched behavior pattern of reaction corresponding to the probability fallen into the random range, the behavior pattern
Including each corresponding speed of point and period on route and route.Wherein: in the behavior pattern of the traffic object model
" speed " is switched over according to population and its mood." route " in the behavior pattern of the traffic object model is according to the population
Motion profile and rate profile determine that the acquisition methods of the motion profile of population are literature survey and sampling in kind, fortune
Dynamic rail mark determines the direction of motion of full ground anthropomorphic robot 1, and the rate that rate profile obtains determines to exist in full ground anthropomorphic robot 1
Motion profile says the movement velocity on determining direction." period " in the behavior pattern of the traffic object model is according to described kind
The motion feature and mood of group determines that the period determines left and right shoulder joint, left and right knee joint or the animal of the adjustable image model 3 of height
The time span of extremities joint one circulation of activity of model 4.
Step 4, external drive has been monitored whether, if so, then entering the incentive mode, otherwise, into the routine
Mode.
In one embodiment, before step 1 further include:
Step 5, the population setting are as follows: the mankind, non-motor vehicle, pet, poultry and livestock, the mood setting are as follows: slow
Slowly, normally and active.The population and mood are built into traffic object library, in the traffic object library: the population
Difference shows as curve shape difference, and the difference of the mood shows as amplitude difference.Wherein, traffic object library can join
Following table 1 (being only for example in table, not all classification) is examined, velocity mode is determined according to population and mood, is specifically included:
It is low-speed mode with the slowly corresponding velocity mode, it is all that the numerical values recited of the low speed can be understood as original period of motion
Velocity amplitude is multiplied by the numerical value after 0.8.It is middle fast mode with the normal corresponding velocity mode, the numerical values recited of the middling speed can
To be interpreted as all velocity amplitudes of original period of motion.With it is described enliven corresponding velocity mode be high-speed mode, the number of the high speed
Value size can be understood as all velocity amplitudes of original period of motion multiplied by the numerical value after 1.25.
