ADAS CAN Outputs - Static Point

This article describes which CAN messages are transmitted from the VB3i when testing to a static target point within a AEB or FCW test.
 

It is possible to output the VBOX ADAS channels to a 3rd party data logger on the VBOX ‘VCi’ CAN port, which is as default assigned to the ‘SER’ connector.

If the 3rd party logger has a 9 way D-sub connector then a RLCAB019L cable should provide the required interface.

Note that when this CAN port is outputting CAN that the VBOX cannot log CAN signals via this port.

All standard and ADAS parameters are output in a set format, which is outlined in the ‘CAN Bus data format’ section below.

It is possible to change the ID of each output CAN message, via the CAN page of VBOX Tools - VBOX setup or VBOX Setup Software.

CAN Signal Latency

The VBOX in vehicle separation ADAS mode will have the following CAN output timings.

47.5 – 49.5 ms delay from ‘ground truth’ to leading edge of the associated CAN message when IMU integration and fixed CAN delay is disabled.

This becomes 60 ms delay when IMU integration or Fixed CAN delay is enabled.

VBOX output CAN message is 5 ms in length at 500 kbit/s.

Standard ADAS CAN Data

Listed below are the standard CAN messages that are transmitted from the VB3iSL-RTK in any mode of operation. The ID’s of the CAN messages can be configured through VBOX Tools or VBOX Setup Software if required.

All channels shown in blue are channels available when Twin antenna mode is enabled.

All CAN id’s highlighted in yellow are not subject to an additional 4 or 5 sample delay that is present when any ADAS mode is enabled.
