Understanding the levels of automated driving

A breakdown of automated driving levels explains the key difference between Level 2, where the driver is responsible, and Level 3, where the car is responsible.

#3about 4 minutes

The architecture of the autonomous driving software stack

The software stack processes data from sensors through perception and fusion layers to create an environmental model, enhanced by a swarm-data-trained behavior map.

Building a neutral cloud-based development playground

A neutral development environment was created on a cloud hyperscaler to support three core feedback loops: the data loop, the deep learning loop, and the DevOps loop.

Evolving the build system from multi-repo to monorepo

Switching from a complex multi-repo structure to a monorepo with Bazel reduced build and integration times from five hours to just ten minutes.

#6about 3 minutes

Scaling the testing pipeline across multiple levels

The testing process scales from cloud-based resimulation to on-target ECU testing in data centers and finally to in-vehicle tests to manage a high volume of daily integrations.

A multi-layered strategy for embedded software validation

Validation is accelerated using a combination of software-in-the-loop, processor-in-the-loop, and hardware-in-the-loop testing to ensure quality before road tests.
