I helped to build a team for Continental several years ago, when sensor fusion was the sexy new thing. The way it was explained to me... people use several senses to perceive the world when driving. Vehicles need to do this to enhance safety. When lighting conditions and road markings are poor, it can rely on LiDAR and radar over and above the computer vision system for instance. We call it Sensor Fusion (usually) when talking about vehicles, but the same concept is helping many applications to do better. Whether it's perception in a robot, or multimodal data powering an advanced LLM for an e-commerce company, adding more ways for a model to perceive the world only increases performance.

Redundancy and reliability are vital for ensuring that autonomous vehicles can operate safely even if some sensors fail or provide inaccurate data. Sensor fusion provides multiple sources of information, allowing the system to cross-verify data and maintain functionality despite individual sensor errors. To enhance redundancy and reliability, implement fail-safe mechanisms, cross-check sensor data, and use robust algorithms to handle discrepancies and sensor malfunctions.

The idea is that autonomous vehicles use multiple sensors like cameras, lidar, radar all working together. So if one sensor feed gets glitchy or drops out, there are backups providing the same info from different angles. It's like having a bunch of eyes on the road instead of just relying on one perspective. The car's AI can cross-reference all the sensor data to get a complete, reliable picture of its surroundings. That redundancy is key for ensuring the system makes smart, safe decisions even if a sensor fails. As an example, let's say a camera gets obstructed but the lidar and radar are still working. The AI can lean more on those sensors to still "see" other cars, pedestrians, obstacles and so on. So it’s super important.
