VEHICLE SENSOR DIAGNOSIS SYSTEM AND METHOD AND A VEHICLE COMPRISING SUCH A SYSTEM
First Claim
1. A vehicle sensor diagnosis system comprising:
- one or more sensors configured to monitor a host vehicle surrounding during driving along a host vehicle route; and
one or more processing units connectable to a database;
the vehicle sensor diagnosis system being connectable to a host vehicle positioning arrangement configured to determine a host vehicle position and driving direction, wherein the vehicle sensor diagnosis system is configured to;
predict, by the processing unit, upcoming vehicle surrounding conditions along at least a section of the host vehicle route based on, information retrieved from the database on the host vehicle surroundings along the section, and information on a current host vehicle surrounding;
estimate, by the processing unit, an expected level of sensor performance for the route section based on the prediction;
assess, by the processing unit, a level of sensor performance detected during host vehicle travel along the host vehicle route section;
assess, by the processing unit, 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, by the processing unit, a diagnosis result communication.

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.

11. A method for diagnosing vehicle sensors with a vehicle sensor diagnosis system comprising one or more sensors configured to monitor a host vehicle surrounding during driving along a host vehicle route and one or more processing units connectable to a database, the vehicle sensor diagnosis system being connectable to a host vehicle positioning arrangement configured to determine a host vehicle position and driving direction, the method comprising:
-
predicting, by the processing unit, upcoming vehicle surrounding conditions along at least a section of the host vehicle route based on, information retrieved from the database on the host vehicle surroundings along the section, and information on a current host vehicle surrounding; estimating, by the processing unit, an expected level of sensor performance for the route section based on the prediction; assessing, by the processing unit, a level of sensor performance detected during host vehicle travel along the host vehicle route section; assessing, by the processing unit, 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; initiating, by the processing unit, a diagnosis result communication.
