Abstract
A vehicle sensor diagnosis system and method, and a vehicle including such a system are provided. The vehicle sensor diagnosis system is configured to predict upcoming vehicle surrounding conditions along at least a section of a host vehicle route based on database information on the host vehicle surroundings along the section and information on a current host vehicle surrounding, estimate an expected level of sensor performance for the route section based on the prediction, assess the level of sensor performance detected during host vehicle travel along the host vehicle route section, assess if a difference between the estimated level of sensor performance and the detected level of sensor performance for the host vehicle route section exceeds a first threshold difference and, if so, initiate a diagnose result communication.
