CAN BUS and Ethernet in automotive

The increase in connectivity has made cars more and more real computers on wheels.

CAN BUS has long been the only choice for communication between control units in cars, now the enormous increase in the data to be transmitted has increasingly pushed manufacturers to choose new solutions by launching the Ethernet standard in the automotive sector.

These innovations have increasingly challenged the dominance of CAN BUS in automotive industy,

the Ethernet standard offers a better solution as a standard for communication backbones with higher speed and greater security.

These innovations have increasingly challenged the dominance of CAN BUS in the automotive industry, the Ethernet standard offers a better solution as a standard for communication backbones with higher speed and greater security.

The technical characteristics of the CAN with greater tolerance to noise and the characteristic of being able to transmit in multicast and broadcast using only two wires makes it very economical even if as the connected devices increase there is a decrease in BUS performance.

With Ethernet technology, devices can be connected and disconnected in real time, without downtime, marking a significant progress compared to CAN-BUS.

To achieve these performances, the CAN BUS requires more connections and components of the Ethernet protocol which translate into higher costs.
