Troubleshooting Workflow

(1) Check whether the data communication link is working properly:

  • Is communication between the SimOne host and the real-time target functioning normally?
  • Is the BridgeIO-IP in TransConfig.ini set to the IP address of the machine running SimOne?
  • Is the CD-IP in TransConfig.ini set to the IP of the real-time target?

(2) Check whether the ego vehicle sensors are configured correctly:

  • Lane line information depends on an object-level camera configured on the ego vehicle.
  • Object-level information depends on an object-level sensor configured on the ego vehicle.
  • GPS and IMU depend on a GPS sensor configured on the ego vehicle.

(3) Check whether the data channel port configuration is consistent:

  • Confirm that the data sending port configuration in TransConfig.ini matches the data receiving port configuration in the Simulation models.

Common Issues

(1) No lane information data received

  • Symptom: No lane line information is received in the SimOneLaneInfo model in VeriStand.
  • Cause: Data link error, or no object-level camera sensor configured on the ego vehicle in SimOne.
  • Resolution: Configure an object-level camera sensor on the ego vehicle model.

(2) Real-time target not receiving data

  • Symptom: After the use case and Trans are running and sensor data has been pushed to the real-time target, the sensor model deployed on the real-time target is not receiving the sensor data.
  • Cause: The ego vehicle and SimOne use case are running normally and Trans is sending data normally. The destination IP address of Trans needs to be verified.
  • Resolution: Check whether the CD-IP in TransConfig.ini matches the IP of the real-time target.

(3) Trans cannot acquire sensor data

  • Symptom: SimOne is running a use case, but Trans is not acquiring data, so the real-time target receives nothing.
  • Cause: The SimOne API in Trans has not detected that the use case is running and cannot acquire sensor data.
  • Resolution: Check whether the address under SimOne → Global Settings → System Settings → IP Address matches the BridgeIO-IP in TransConfig.ini.
