Vehicle control system and vehicle control method

A vehicle control system comprising:

• a plurality of sensors, each of which is configured to detect an object in an external field of an own vehicle in accordance with a characteristic of each sensor;
• and
• one or more memory devices having a program stored thereon that, when executed by one or more processors, cause the one or more processors to:
• estimate information on a position and a speed of a target detected by at least one of the plurality of sensors,
• estimate, based on a detection result, the characteristic, and a type of the at least one sensor, an error of the detection result and a range of the error,
• based on the error and the range of the error, determine correlation between detection results for targets detected by at least two of the plurality of sensors,
• determine whether to recognize the targets as the object by integrating correlated detection results, and
• calculate the errors of the position and the speed of the target object, wherein the vehicle control system controls the own vehicle based at least in part on calculated errors of the position and the speed of the object.
