Updating driver behavior parameters at the run time

All Foretellix Human Driver Model behavior parameters can be updated by calling the update_config function during runtime. You can find these parameters in the parameter tables of the specific behavior section in this documentation.

To update behavior parameters at the run time:

  1. Set a new behavior_param value.

  2. Call the update_config.

    In the log file you can see, "“BEHAVIOR NAME” :update_config is called“.

The following example shows how to set a new distance_from_stop_line value:

extend sut.example:
    # event to trigger update the distance_from_stop_line of the junction_behavior
    # the change happens at time 1 second - so from this simulation time onwards the new parameter value will be active
    on @top.clk if (top.time == 1s):
        #define a new value for distance_from_stop_line
        sut.car.ftx_driver.junction_behavior.distance_from_stop_line = 1.5m
        #call to update_config function to update the config param of junction behavior
        call sut.car.ftx_driver.junction_behavior.update_config()

Similarly, you can call update_config for other behaviors.
