Method and system for assessing the correctness of information transmitted by a vehicle

A remote server for establishing a chain of vehicles with updated vehicle trust values, comprising repeating a cycle, wherein said cycle comprises:

• receiving vehicle information about vehicle characteristics of a first vehicle, wherein a vehicle trust value is assigned to said first vehicle;
• receiving detector information about said vehicle characteristics, which is based on a detection of said first vehicle characteristics by at least one detector outside said first vehicle, wherein a detector trust value is assigned to said detector;
• assessing the correctness of said vehicle information based on said vehicle information, said vehicle trust value, said detector information, and/or said detector trust value;
• assigning a correctness value to said vehicle information based on said assessment;
• update the vehicle trust value based on said vehicle information, said vehicle trust value, said detector information, and/or said detector trust value;
• identifying said first vehicle, wherein said identifying comprises:
• sending information about a predetermined light sequence to said first vehicle, wherein said predetermined light sequence activates one or more vehicle lights of said first vehicle in accordance with said predetermined light sequence;
• wherein said detector information comprises information about a light sequence of one of more vehicle lights detected by said detector;
• identifying said first vehicle based on a comparison of said predetermined light sequence with said detected light sequence;
• and
• processing said vehicle information using said correctness value;
• wherein said detector in a cycle n is said first vehicle with an updated vehicle trust value assigned to the first vehicle in cycle n−1 and wherein said detector in a cycle n+1 is a second vehicle such that an ability of the second vehicle to be the detector in cycle n+1 depends upon an ability of the first vehicle to be the detector in cycle n;
• wherein said detector in the cycle n−1 is a roadside unit with a high detector trust value.

A system for assessing the correctness of information transmitted by a vehicle, comprising:

• a remote server for assessing the correctness of information transmitted by a first vehicle, arranged for establishing a chain of vehicles with updated vehicle trust values, comprising repeating a cycle, wherein said cycle comprises:
• receiving vehicle information about vehicle characteristics of a first vehicle, wherein a vehicle trust value is assigned to said first vehicle;
• receiving detector information about said vehicle characteristics, which is based on a detection of said vehicle characteristics by at least one detector outside said first vehicle, wherein a detector trust value is assigned to said detector;
• assessing the correctness of said vehicle information based on said vehicle information, said vehicle trust value, said detector information, and/or said detector trust value;
• assigning a correctness value to said vehicle information based on said assessment;
• update the vehicle trust value based on said vehicle information, said vehicle trust value, said detector information, and/or said detector trust value;
• identifying said first vehicle, wherein said identifying comprises:
• sending information about a predetermined light sequence to said first vehicle, wherein said predetermined light sequence activates one or more vehicle lights of said vehicle in accordance with said predetermined light sequence;
• wherein said detector information comprises information about a light sequence of one of more vehicle lights detected by said detector;
• identifying said first vehicle based on a comparison of said predetermined light sequence with said detected light sequence;
• and
• processing said vehicle information using said correctness value;
• said detector outside said first vehicle arranged for detecting said vehicle characteristics of said first vehicle and sending detector information about said detected vehicle characteristics by said detector to said remote server;
• wherein said detector in a cycle n is said first vehicle with an updated vehicle trust value assigned to the first vehicle in cycle n−1 and wherein said detector in a cycle n+1 is a second vehicle such that an ability of the second vehicle to be the detector in cycle n+1 depends upon an ability of the first vehicle to be the detector in cycle n;
• wherein said detector in the cycle n−1 is a roadside unit with a high detector trust value.
