Advanced GNSS Algorithms for Safe Autonomous Vehicles

Abstract:

The main concern of autonomous driving (AD) is the safety of human beings, both inside and outside the vehicle. Safety depends on a wide variety of complex factors such as vehicle speed, weather, state of the road, complexity of the environment (surrounding vehicles, pedestrians or obstacles), or situational awareness, among others. In order to cope with these factors, different sensors are placed in the vehicle to measure dozens of parameters (absolute speed, distance to surrounding vehicles and pedestrians, relative speed, absolute position, distance to next crossing, etc.). Accurate knowledge of these and other parameters is a key to safety, but even more important is to ensure their reliability. Such guarantee on reliability is what the aviation community refers to as integrity. The implementation of an integrity layer is crucial since in safety-critical applications it can be more important to know whether information …
