470. New Car Assessment Program (NCAP) introduction

New Car Assessment Program (NCAP) is a set of ADAS functions that help in evaluating and assessing automobile performance against various safety threats.

NCAP Directory Structure

The New Car Assessment Program (NCAP) library components are located in $FTX_PACKAGES/adas/NCAP as shown in Figure 1.

Figure 1: NCAP directory structure

The scenario families covered in NCAP are described in the following table:

Directory/File Description
EuroNCAP_AEB_C2C A directory containing the components for Euro NCAP AEB car-to-car scenarios
EuroNCAP_AEB_LSS_VRU A directory containing the components for Euro NCAP AEB/LSS VRU scenarios
EuroNCAP_LSS A directory containing the components for Euro NCAP LSS scenarios
common A directory containing the library components shared by EuroNCAP_AEB_C2C, EuroNCAP_AEB_LSS_VRU, and EuroNCAP_LSS

The subdirectories within the EuroNCAP_AEB_C2C, EuroNCAP_AEB_LSS_VRU, and EuroNCAP_LSS directories are described in the following table:

Directory/File Description
test_suite_definitions A directory containing CSV files for executing the EuroNCAP_AEB_C2C, EuroNCAP_AEB_LSS_VRU, or EuroNCAP_LSS tests with FRun
example_test_cases A directory containing example test files for running a single test with Foretify
scenarios A directory containing the OSC2 source files for each scenario
templates A directory containing the templates used to generate tests to be executed with FRun

The subdirectories within the common directory are described in the following table:

Directory/File Description
activation_coverage A directory containing the metrics that evaluate how well the system's behavior is exercised across various scenarios that trigger its activation
ncap_config A directory containing the OSC configuration files that import ADAS functions
utils A directory containing files required for integrating user-defined C++ functions with Foretify

To run a single test with Foretify:

  1. Invoke Foretify with a test file from the example_test_cases directory.

    For example: 

    $ foretify --load $FTX/packages/adas/NCAP/EuroNCAP_AEB_C2C/test_suites/example_test_cases/t_aeb_car_to_car_rear_braking.osc
           --load $FTX/packages/adas/NCAP/common/ncap_config/lss_carla_config.osc 
           --run
    In this example, the configured simulator is CARLA.

  2. Enter quit at the "Foretify>" prompt, after the completion of run.

To run a set of tests with FRun:

  1. Invoke FRun in batch mode with all the CSV files required for the set of tests that you chose.

    For example: 

    frun --csv $FTX_PACKAGES/adas/NCAP/EuroNCAP_LSS/test_suites/test_suite_definitions/bsm_motorcycle_overtaking_main.csv 
     --csv $FTX_PACKAGES/adas/NCAP/EuroNCAP_LSS/test_suites/test_suite_definitions/bsm_motorcycle_overtaking.csv 
     --csv $FTX_PACKAGES/common/csv/uncontrolled_carla_config.csv
     --batch
    2. Review the regression results in the default work directory:

    ~/foretify/sessions/<timestamp>/<timestamp>/

To run all the NCAP tests at once:

```bash
frun --file $FTX/packages/adas/NCAP/EuroNCAP_AEB_C2C/test_suites/test_suite_definitions/euroncap_aeb_c2c.txt
     --file $FTX/packages/adas/NCAP/EuroNCAP_AEB_LSS_VRU/test_suites/test_suite_definitions/euroncap_aeb_lss_vru.txt
     --file $FTX/packages/adas/NCAP/EuroNCAP_LSS/test_suites/test_suite_definitions/euroncap_lss.txt 
```
