utomotive innovation has majorly been in hardware during the last two decades. For instance, the efficiency of internal combustion engine has considerably increased during this time. However, during the last few years, the focus of automotive industry has shifted towards digitalisation, automation and electrification. The cars of the future will be electric, connected and autonomous. They will continuously accumulate, process and share data received from sensors and infotainment systems. By 2025, we expect, around 30% of cars sold

globally will support Level 2 or above automation. Advanced Driver Assistance Systems (ADAS) having multiple sensors will form the foundation of autonomous vehicles (AVs). The exhibit below highlights the increasing number of advanced sensors required for the goal of achieving highly or fully-automated driving. Vehicles will be increasingly designed to gather, process and store data locally as well as selectively upload data at an appropriate time. This will create a need for data storage and computing infrastructure within the car, as well as in the cloud.
How Much Data Will AVs Generate? AVs will generate huge amounts of data, not all of which will be stored in the vehicle. Some of it will be discarded or transferred to cloud. It is difficult to accurately gauge the amount of data generated by an AV. Data generated by a sensor depends on its application and specifications. For instance, data generated by a front camera could range between 70 GB/hr and 300 GB/hr depending on its resolution, color depth, frame rate and compression levels. The amount of data generated by an AV will also depend on the type
