Modern electric vehicles (EVs) are mechatronic machines that combine electric propulsion, electronic control, mechanical actuators, and extensive sensor packages, to create a vehicle that is more intelligent, more efficient, and safer than traditional fossil fuel vehicles. And as they evolve, they are laying the foundations for true autonomous operation. The lifeblood of these systems is the trustworthy communication of data between the driver and the vehicle, the vehicle, and its environment, and the transfer of data among the different systems of the vehicle itself.
