Abstract
Various and natural traffic environment is expressed by making action of each object which appears in scenario be performed autonomously, and a new scenario is easily constituted. When an operator drives a moving object for driving simulation in a virtual scene, other moving objects move as surrounding environment. Each moving object acknowledges and predicts a surrounding state by the surrounding environmental data in a presumption stage, and determines the action to be taken next, according to the result and characteristic of a moving object characteristic data associated with each moving object in an action judgement stage. Each moving object takes action given by an action data which is determined by a motion determination section in an action stage. The operator can see the action by the surrounding environment and each moving object characteristic, when the moving object exists within sight of a viewing field and the natural traffic environment is realized. By changing the characteristic of the moving object characteristic data, user's own scenario can be created within its range.
Description
Technology neck city
The present invention relates to by computer-controlled driving simulator, relate to the method and the device of mobile object motion that control becomes the surrounding environment part of the simulation mobile object that the operator drives.
Background technology
Pass through driving simulator, according to the script that is programmed in advance, in the virtual sight of regulation, carry out driver behavior, with driving technology and the safe driving consciousness that improves the operator, perhaps produce the situation be used for various education or research purpose, the operator is experienced or test processing it.
In the prior art, appear at vehicle in the script and personage's etc. mobile object,, speed, position and the direction of each object are encoded respectively according to the position of its appearance.The motion of predesignating, thus constitute script.
Appear at each object in the script, because will make its action based on position, speed, the direction order of object and dependence coordinate, so in order to constitute script, must at length provide the motion indication to all objects, in addition, because have only the control of regulation, so be difficult to make traffic environment to change naturally, this traffic environment is from the operator, be manifest in the virtual sight, produced by the driver's who drives other vehicles diversity operation.
Therefore, aforementioned mobile object except the simulation mobile object that the operator drives, always done identical motion on the virtual location that shows, therefore be difficult to be implemented in take place on the real road, drive the natural traffic environment that produces by driver's diversity.In addition, reconstitute script and cause very big cost burden.

Embodiment
(function formation portion)
Fig. 1 (a) is a functional block diagram of using driving simulator of the present invention, the 101st, and real-time control part, the 102nd, script control part, the 103rd, mobile object control part, the 104th, drawing section, the 105th, mobile object performance data portion, the 106th, environmental data portion.Fig. 1 (b) is the built-in function block diagram of the mobile object portion 103 among Fig. 1 (a), the 111st, and supposition portion, the 112nd, judging part, the 113rd, action portion, the 114th, the computing machine that control is whole.
(explanation of each function portion)
Mobile object control part 103 utilizes that each that appear at vehicle on the script, personage etc. as mobile object independently inferred, evaluation algorithm, determines their autonomous action.
Mobile object performance data 105 is set each aforesaid mobile object, if this mobile object (model) is a vehicle, then set car type, type (differences of common car, light-duty vehicle, general wagon etc.), route information and (, be set in advance in the place that to realize driving simulator for each mobile object.), peak acceleration is (according to the people's who drives mobile object property prediction, acceleration when for example setting out), maximum deceleration is (according to the people's who drives mobile object property prediction, retarded velocity when for example braking), braking property (according to vehicle, configuration status and the equipment situation of different brakes, promptly strong, in, weak) etc.If this mobile object (model) is the people, then set sex, height, age and physical trait etc.The content of each project of mobile object performance data 105, the user can upgrade.
Be set in the position of each road junction that exists on the map of the region that will realize driving simulator in environmental data portion 106, the crossing has under the situation of signal lamp sets the position of single display mode, road, the number of track-lines of this road etc.
Judging part 112 is based on identification in aforementioned supposition portion 111, prediction result and mobile object performance data that aforementioned each mobile object is distributed, to each mobile object except the drive simulating mobile object that the operator drives, in predetermined judgement level described later, determine the driver behavior that next should carry out.
The mobile data that action portion 113 is judged by aforementioned judging part 112 each mobile object output.
(action specification)
Below, the action of the mobile object control device in the driving simulator of such formation is described.
Fig. 2 is the process flow diagram of the action of explanation present embodiment.
In script control part 102, distribute its intrinsic separately characteristic for each pedestrian and vehicle based on mobile object performance data 105.When operator's drive simulation is driven the position of mobile object arrival regulation, then make as the pedestrian that should appear at the mobile object in this scene, vehicle to occur according to script.In mobile object control part 103.Based on environmental data portion 106, to the own traffic environment on every side of each aforementioned mobile object identification, and the prediction action (step ST1 (supposition stage)) of mobile object on every side.
In the judging part 112,, carry out driving judgement (step ST2 (judgement stage)) alone in action based on to the data of each mobile object in the mobile object performance data portion 105 of the identification of aforementioned supposition stage, prediction result and each mobile object.Independently judge alone action according to the data of mobile object performance data portion 105, can realize the traffic behavior of nature thus, the content of projects of mobile object performance data 105, the user can upgrade, to realize the traffic environment of its hope.
Here, judge level as shown in Figure 3, for example 7 levels (LEVEL) are arranged, promptly usually level (LEVEL1), may level (LEVEL2), level (LEVEL3), prevention level (LEVEL4), restriction level (LEVEL5), defence level (LEVEL6) and accident level (LEVEL7) smoothly.Its content separately as shown in Figure 3.In level, the digital big of LEVEL is upper layer.Judgment processing is that the common level (LEVEL1) from lower layer improves level successively and carries out until accident level (LEVEL7).Decision content in each level is cancelled in order to guarantee upper layer sometimes.That is to say, for example, because there is not relative driving vehicle, so be judged as " travelling " in the level (LEVEL1) usually to target velocity, but because because of judging successively, in the prevention level of LEVEL4, be judged as " guaranteeing the place ahead safe distance ", then cancel the judgement of in aforesaid common level (LEVEL1) " travelling " sometimes to target velocity.
After a series of processing of the mobile object that appears at the model 1 in the script being finished from this step 1 to step 3, then the mobile object of next model is handled, thereby all mobile objects are carried out these processing successively.
With the cycle of regulation, carry out repeatedly from the real-time control part 101 of Fig. 1 (a), arrive script control part 102, mobile object control part 103 so that the processing of drawing section 104.
