3.2.1 Test Setup

Sensor Mounting Position: The sensor was mounted on the ceiling of the vehicle centered over the console separating the driver and passenger seat.

Zone Definitions: Based on the mounting position of the sensor. The XYZ definitions of each zone (seat) position in the car was measured and updated in the chirp configuration file. The demo project provides example chirp configurations for each use case and supported device. These files are located in the /chirp_configs folder of the demo. NOTE: Due to variations in mounting position and vehicle geometries, users should measure and update zone definitions for their test setup in the configuration file. Details are provided in the demo user guide with the downloaded software.
