Abstract

A vehicle sensor diagnosis system (1) and method (100) and a vehicle (2) comprising such a system (1) are provided. The vehicle sensor diagnostic system (1) is arranged to: predict a route along the host vehicle based on information about the surroundings of the host vehicle along the segment and information about the surroundings of the current host vehicle retrieved from a database (8). upcoming vehicle surrounding conditions for at least one segment of the route, estimating an expected sensor performance level for the route segment based on the prediction, evaluating the detected sensor performance level during the ego vehicle traveling along the ego vehicle route segment , evaluating whether a difference between the estimated level of sensor performance and the detected sensor performance level within the host vehicle route segment exceeds a first threshold difference and if so, initiating transmission of diagnostic results.

Description

technical field [0001] Embodiments herein relate to vehicle sensor diagnostic systems. Embodiments herein also relate to a vehicle including a vehicle sensor diagnostic system and a method for diagnosing a vehicle sensor. Background technique [0002] Some of today's vehicles are equipped with various driver support systems, such as predictive safety systems and adaptive cruise control systems. The purpose of these systems is usually to increase driver safety and / or comfort. Some systems assist the driver in tasks he or she would need to do manually, such as keeping the vehicle within a specific lane or maintaining a distance from the vehicle in front. [0003] To provide these semi-autonomous or autonomous functions, vehicle systems often monitor the vehicle's surroundings using several vehicle sensors. Sensors provide the system with information about surrounding vehicles, obstacles and road signs. Accordingly, vehicle systems rely on reliable sensor information in ord...
