Partitioning enables updates in the field and makes electronics safer

Where control unit software is concerned, the automotive industry increasingly relies on agile software development. With agile software development, software-controlled vehicle functions are kept current via continual updates and upgrades -- also in the field. For these updates to be installed without safety risks, the individual functions must be kept absolutely separate. At same time, the trend is towards increasing connectivity of ever more functions on central control units. Partitioning is a way of solving this contradiction. Previously, this was not technically possible with the microcontrollers in automotive control units. The Lightweight Hypervisor from ETAS is the answer.
