signal set to invalid). Validity signals to be monitored have to be specified in
the “target vehicle” CAN database.
•
Loss of transmission: a required CAN signal is not available or has not been
received according to LOSS OF TRANSMISSION timeout. The signals to
be monitored for loss of are specified in the “target vehicle” CAN database.

when the parking brake is set. Radar transmission to monitor the field of view is
not performed while in this state.
4.1.3.9. SYSTEM ACTIVE state
In this state, the field of view of the sensor is constantly monitored.
4.1.4. HMI output function
Each sensor has CAN signals for independently controlling an alert display and a
status message. Each rBLIS Sensor provides independent displays for its own
side of the vehicle. No other directly controlled (e.g. audible) alert will be provided.

CAN communication shall be provided through a two wire transceiver, compliant
with the specifications listed in section 2.3. The required CAN messages, CAN-ID
