Prescan quick start to master Lesson 19: prescan actuator configuration, track synchronization and non configuration of multiple tracks

19.1 Actuator configuration

After creating a set of tracks , Can pass " actuator ( Actuator refers to the target object that can be dynamically controlled in the simulation process ) Object configuration " The dialog box assigns these tracks to the vehicle . This is shown in the figure below . About the actuator and its trajectory Follow up explanation , Welcome to your attention .

The trajectory assigned to a specific car can be found in the experiment tree ：Linked_to_Trajectory_1.

stay " Build area " in , For trajectory "+"- Symbolic representation . If an actuator is assigned to a track , Then use 'o'- Symbolic representation .

Although you can assign multiple tracks to a car , But only one track is active . Only the active track can be in GUI and VisViewer Animated .

19.2  Trajectory synchronization

Track synchronization involves time matching at specific positions selected on different tracks . for example , Trajectory synchronization can be used to simulate the collision between actuators , Or simulate complex manipulation involving multiple actuators . Think about it , When the third car is driving in the opposite lane , One car tries to overtake another , The third car is driving in the opposite lane . Another example relates to the traffic flow entering the roundabout . These two examples are shown here .

Synchronization

If you want to synchronize tracks , You need to select a vehicle as the reference vehicle for synchronization . The trajectory of other vehicles will change relative to the reference trajectory . This can be done by connecting the end of these tracks with / Or automatically join the waiting at the beginning , And shorten these tracks
