STV2 is a set of processes that support the development, validation, and operation of autonomous driving systems from the perspectives of safety and cost. The scope, architecture, and critical components of STV2, as well as how the full lifecycle of autonomous driving systems is covered, is presented in this white paper. STV2 is part of the infrastructure and tooling layer of autonomous driving architecture. STV2’s business objective and process are fulfilled by a simulation system supported by data infrastructure as described in this white paper
