  • Page 11 Setup Guide M212169EN-D Check that the mobile sensor is powered and operational (green LED in the mobile sensor is blinking). Check that there are no error messages by scrolling right in the RoadAI app measurement grid. In RoadAI mobile app, go to the menu and select Set Reference > Plate Reference. The adjustment takes typically 30 seconds.
  • Page 12 Setup Guide M212169EN-D Calibration step 3: dry road reference Sensor needs a reference of how local dry road looks like. The reference setting is performed while driving on the most common road surface type in the road network. This optimizes the sensor performance on the road type in question.
  • Page 13 Setup Guide M212169EN-D Option B: using factory coefficients Recommended to use factory default coefficient values if typical local dry road is not available and the values cannot be copied from another sensor for which dry reference has already been done. In the RoadAI app, scroll right in the measurement grid to check that the sensor uses the following co-efficient values: 3.696, 3.729, and 3.664 If not, select Set Reference >...
  • Page 14 Setup Guide M212169EN-D For the sensor that you want to calibrate, go to the RoadAI app, select Set Reference > Manual Road Reference, and type the 3 values. Verifying RoadAI operation Connect the mobile sensor and mobile device to the vehicle power outlet. Start the car. In RoadAI mobile app, enable Auto-record.

  • Page 22 Setup Guide M212169EN-D Drive for a minimum of 30 seconds on dry road. 30 s This changes road coefficient parameters 0x53, 0x54, and 0x55 (1 parameter for each laser). • When started, changes status bit reference setting ongoing to 1 = ongoing. When finished, changes back to 0 = not ongoing.
