The exponential increase in the number and complexity of in-vehicle electronics has transformed the automobile. At one time, the car was primarily an assembly of mechanical components; it has now become a system that integrates both mechanical and electronic components, with the electronic components representing a substantial portion of the added value and a disproportionate share of the headaches.
In modern cars, dozens of computers and hundreds of sensors continuously generate, store and transmit data. Only the car manufacturers know what are those data. Based on the example of three vehicles – Mercedes-Benz B-series, BMW 320d and i3 as well as Renault Zoe - the German motor club ADAC has examined which data are sent to the manufacturer.
The advent of advanced assisted drive functions and autonomous vehicles will require a transformation in the architecture of automobile control systems. Today’s car has typically more than 50 electronic control units (ECU) managing most aspects of the vehicle’s performance and behavior.
Many cars on the road today, and even more new cars in the show rooms, have some form of advanced driver assistance system (ADAS) based on sensors like cameras, radar, ultrasound or LIDAR.
