All-round vision camera control unit

The light spots, light colors and light intensities recorded by the camera are transmitted to the TRSVC control unit via Ethernet.

Standard Ethernet: 

Ethernet is a technology that specifies software (e.g. protocols) and hardware (e.g. cables,) for wired data networks. The combination corresponds to a local Network (LAN = local area network). The local network enables the data exchange in the form of data packets between the components which are connected in a local network. Transmission rates of 10 MBits/s are currently specified.

The TRSVC control unit is connected to the K-CAN2 (I01 at K-CAN3). The all-round vision camera control unit is supplied by the rear power distribution box via terminal 15N. The all-round vision camera control unit provides the voltage supply for each of the cameras.

Depending on the vehicle equipment, the video signal is transmitted by the all-round vision camera control unit over the CVBS line (Color Video Blanking Signal):

• On the video switch (VSW) which forwards the video signal to the headunit
• On the headunit itself.

The headunit transmits the prepared video signal via an APIX data cable to the central information display.
