Ultrasonic interior movement detector
The ultrasonic interior movement detector captures and evaluates movements in the vehicle interior. Initialization of the ultrasonic interior movement detector is started 6 seconds after the hood, trunk lid and the last door have been closed.
The ultrasonic interior movement detector is operational 30 seconds after the start of initialization and is included in the vehicle monitoring system. The ultrasonic interior movement detector has been integrated into the roof function center. The FZD is connected to the K-CAN2 and DWA bus.
