Figure.By Orientation on map, increased in binding test field using the GPS/ the North ground based on RTK (carrier phase difference) location technology
Strong system, it can be achieved that vehicle Centimeter Level high accuracy positioning.
In a kind of possible embodiment, the specific embodiment of step S111, as shown in Figure 3, comprising:
Step S1111: the field data of the scene to be reproduced is extracted.
In the specific implementation process, accident scene or normally travel that scene to be reproduced can be to be reproduced for automatic Pilot vehicle
Scene.All accidents that front and back certain period of time occurs for accident can be extracted for accident scene to be reproduced, in step S1111
The location data of associated vehicle.Location data can be extracted from accident vehicle on-board positioning device, the vehicle-mounted band positions function
The equipment of energy includes Vehicular satellite positioning device, on-vehicle navigation apparatus etc..In general, vehicle equipped with navigation or automobile positioner, one
As be GPS (Global Positioning System, global positioning system) or BDS (BeiDou Navigation
Satellite System, Beidou satellite navigation system).It in the specific implementation process, can be from navigation or vapour in step S1111
All positioning of front and back a period of time (such as front and back 1 minute or 2 minutes or 5 minutes) occur for the accident that vehicle is exported in vehicle locator
Data, including longitude, latitude, elevation, speed, acceleration, traveling azimuth, time.
For automatic Pilot vehicle, vehicle positioning equipment is widely used that RTK positioning, Orientation on map and inertia measurement
The fusion of unit can reach a centimetre class precision.For error caused by precision low on general vehicle navigation or locator, use
Field observation the methods of is taken pictures, and traveling trace, braking mark, the vehicle-mounted video recording, road surface monitoring video on road surface are stayed in conjunction with wheel
Equal analyses obtain, to determine navigation or the specific position of locator.
Step S1112: according to the field data, the scene overall process to be reproduced is emulated, obtains the field to be reproduced
The preliminary simulation model of scape.
According to the positioning data of vehicles that step S1111 is collected, in conjunction with the model of vehicle, initial position, driving condition parameter
(such as acceleration and deceleration, braking, steering) establishes the complete mathematical model of accident process, based on checkout area high-precision map to accident
Process carries out digital to analog simulation, reproduces the overall process of car accident.Entire simulation process is on the server of control centre
It carries out.
By above step, the preliminary simulation model of scene to be reproduced is obtained, model parameter includes accident associated vehicle
Initial position, track, speed, traffic injury time etc..
Step S1113: adjustment model parameter optimizes the preliminary simulation model until kissing substantially with the scene to be reproduced
It closes, obtains simulation model.
But the preliminary simulation model due to acquisition is with scene to be reproduced that there may be not very identical situation, step
S1113 optimizes the preliminary simulation model until coincideing with the scene to be reproduced, obtains emulation mould for adjusting model parameter
Type.
Step S1113 is optimization primary condition with the PRELIMINARY RESULTS of step S1112, by repeatedly adjusting vehicle location, speed
The model parameters such as degree, actuation time optimize Failure Simulation process, until analog result and truth substantially conform to.
Step S1114: it according to the simulation model, generates for controlling the automatic Pilot vehicle and the operation of unmanned testing vehicle
Instruction sequence.
In the specific implementation process, model of place interpreter can read the data information of simulation model, parse therein
Data sequentially generate the instruction sequence of control vehicle operation.When instruction sequence includes position, movement and the execution of associated vehicle
Between, track, the information such as speed, as shown in the table.
Wherein, position coordinates are WGS84 coordinate, and the node of track includes the information such as vehicle location, moment, speed.
Step S1115: described instruction sequence is sent respectively to the automatic Pilot vehicle and unmanned testing vehicle, so that described
Automatic Pilot vehicle and unmanned testing vehicle carry out scene reproduction in the checkout area.
Control centre will control the instruction sequence of automatic Pilot vehicle and the operation of unmanned testing vehicle by instruction publication submodule
It is sent respectively to automatic Pilot vehicle and unmanned testing vehicle, so that automatic Pilot vehicle and unmanned testing vehicle carry out in the checkout area
Scene reproduction.

Examination hall car networking environment is in real time sent to instruction sequence automatic Pilot vehicle and unmanned testing vehicle.Automatic Pilot vehicle and unmanned survey
After test run receives control instruction, scene reproduction is carried out in checkout area.
Step S1116: according to the scene reproduction as a result, adjustment model parameter, until scene reproduction result with it is described
Scene to be reproduced is coincide.
It, can not completely truly again according only to the model of place of emulation due to the otherness of simulated environment and actual environment
Existing actual scene.Therefore, the result of scene reproduction can not truly reproduce scene to be reproduced completely in step S1114, also need
Accident process is repeated several times, directly by further adjusting the model parameters such as speed, position, movement execution time, running track
Reconstruction results in checkout area are substantially conformed to truth, to obtain scene reproduction model.
The scene reproduction model that step S111 is obtained includes the data of scene to be reproduced from start to finish entire motion process
File specifically includes following data information: controlled vehicle starts state (position, posture, initial velocity etc.);Controlled vehicle intermediate state
(position, posture, speed, track, movement etc.);Controlled vehicle final state (position, state, final speed etc.).
Step S112: according to the scene reproduction model, automatic Pilot vehicle and unmanned testing vehicle are controlled in checkout area
Realize scene reproduction.
In a kind of possible embodiment, according to the scene reproduction model that step S111 is obtained, needing to be reproduced
When scene is reproduced, according to the data file of the model, instruction sequence can be generated by model of place interpreter, then by referring to
Enable publication submodule be sent to automatic Pilot vehicle and unmanned testing vehicle by checkout area car networking environment, control automatic Pilot vehicle with
And unmanned testing vehicle realizes scene reproduction.
Step S113: the data letter of the automatic Pilot vehicle and unmanned testing vehicle in scene reproducing processes is obtained in real time
Breath.
By checkout area car networking environment, the data of automatic Pilot vehicle and unmanned testing vehicle in scene reproducing processes are believed
Breath transmit simultaneously save the server to control centre, data information includes: vehicle location, azimuth, motion track, speed and
Sensor information etc.;The intermediate output of the modules such as environment understanding, the programmed decision-making of automatic Pilot vehicle (tested vechicle) is as a result, include vehicle
Self-positioning information, the identification information of lane line, traffic signals, barrier, pedestrian, the identification of background vehicle (test carriage) and fixed
Position information and path planning, action selection, track generate etc. result information.Certainly in the specific implementation process, checkout area one
As be fitted with video monitoring system, the on-site supervision video as captured by checkout area video monitoring system can also be for transmission to control
Central server processed;If automatic Pilot vehicle and unmanned testing vehicle installation automobile data recorder or in-vehicle camera, by automobile data recorder
Or process video captured by in-vehicle camera can also be transferred to server, so that server obtains more data, more favorably
In the parsing of cause of accident.
