On-vehicle system, externality recognition sensor, electronic control device

An externality recognition sensor to be mounted in a vehicle, comprising:

• a sensing unit that acquires pre-processing externality information through sensing operation;
• a reception unit that acquires a processing condition which is created on the basis of a position of the vehicle, traveling direction of the vehicle, and map information and in which information identifying an area on the map is associated with processing priority of the pre-processing externality information acquired by the externality recognition sensor;
• and
• a processing object determination unit that, on the basis of the pre-processing externality information and the processing condition, creates externality information having a smaller amount of information than the pre-processing externality information,
• wherein the externality information includes probability indicating a degree of correctness, and
• the condition calculation unit corrects the processing condition according to the probability.

An electronic control device to be mounted in a vehicle and connected to an externality recognition sensor that acquires pre-processing externality information through sensing operation,

• the electronic control device comprising:
• a condition calculation unit that, on the basis of a position of the vehicle, traveling direction of the vehicle, and map information, calculates a processing condition in which information identifying an area on the map is associated with processing priority of the pre-processing externality information acquired by the externality recognition sensor;
• a pre-processing externality information acquisition unit that acquires the pre-processing externality information from the externality recognition sensor;
• and
• a processing object determination unit that, on the basis of the pre-processing externality information and the processing condition, creates externality information having a smaller amount of information than the pre-processing externality information,
• wherein the externality information includes probability indicating a degree of correctness, and
• the condition calculation unit corrects the processing condition according to the probability.
