STISIM Drive (SDL) - CV - Control Vehicle

Control the vehicle automatically. In the program's Configuration form (in the "Options" menu) there is an option to use an automatic pilot (Autopilot mode under the I/O Control tab). The automatic pilot is limited in that it controls both the steering and the speed for the entire simulation run. Unlike the Autopilot option, this event allows the scenario designer to control either the steering, the speed or both. Furthermore, you can change what the driver is controlling in the middle of a run. This is ideal for training drivers on how to use the steering and accelerator. The CV event can only be used on systems running the simple dynamics. Advanced dynamics systems may hang during curves if the CV event is used.

EVENT PARAMETERS:

PARAMETER 1:

The speed, in feet/second, that the vehicle will be traveling. If this value is set to 0, then the driver will have control of the accelerator.

PARAMETER 2:

Flag giving the driver control of the steering wheel. To specify the steering wheel control option, set parameter 2 to one of the following: 0 - Driver controls the vehicle's steering. When this value is used, the program returns the crash parameters to the values that were set before the previous CV event was processed. See the CSET event. 1 - Driver controls the vehicle's steering and all crashes will be ignored 2 - Computer controls the steering and all crashes will be ignored

EXAMPLES:

0,CV,0,2
1000,CV,80,1
2000,CV,0,0

This event is usually associated with training drivers. One of the problems you have with a simulator is allowing the driver to get familiar with the different control aspects, in this case throttle, brake and steering. This event was included so that you can selective turn the steering and pedals on and off so that the driver can concentrate on controlling only one aspect of the simulator at a time.

The examples shown could be used as part of a training scenario. The first line sets the system so that as soon as the run begins the driver will have control of the throttle and brake (speed is set to 0), and the steering will be controlled by the computer. This will allow the driver to become familiar with the simulator’s pedals. The second line tells the software that after the driver has traveled 1000 feet down the road, the computer will control speed (80 feet/second) and the driver will be given control of the steering wheel (1). This allows the driver to become familiar with the simulator’s steering system. The final line gives total control of the simulator (both steering and pedals) to the driver.
