Meet the CAN Invader – How Can Automotive Ethernet Curb Car Theft?

Claude Gauthier, Director of Strategic Innovation for Automotive Ethernet Solutions in NXP’s In-Vehicle Network Group, presented that part of the keynote. Figure 1 illustrates the growing bandwidth needed in these evolving in-vehicle networks through the thicker and thicker lines used to interconnect various functions. Overall, cameras consume 90 percent of a car’s network bandwidth, he explained. He made the following comparisons:Skeletal and nervous systems – Vehicle electrical/electronic architecture, networking, sensorsMuscular system – Vehicle dynamics control (motor, traction control, chassis, etc.) However, the exponential increase in the use of electronics in vehicles now demands more performance than the CAN Bus can provide, while efforts like the Automotive SerDes Alliance continues to reduce the cost of automotive Ethernet networks, so the shift to Ethernet is inevitable.
