A center prescribes, to a subject vehicle through wireless communication, at least one of a type of vehicle data to be collected, a conditional expression used when collecting the vehicle data, a sampling cycle when collecting the vehicle data, and a checking cycle of the conditional expression. A center-side checking section checks, based on its own check criterion, appropriateness of at least one of the type of the vehicle data, the conditional expression, the sampling cycle, and the checking cycle. A vehicle-side checking section checks whether the resources of the subject vehicle are appropriate when the vehicle data is collected based on the prescription from the center.

Remote vehicle data collection system

A vehicular drive assist system performs drive assist for a vehicle traveling in each predetermined area while receiving a feedback on evaluation relating to ease of travel on a road in each of the areas. In the system, a management center performs evaluation of ease of travel on a road for each of the areas on the basis of information obtained from the vehicle and feeds back the evaluation result to the vehicle. In this case, a variation width of the evaluation relating to ease of travel is restricted on a basis of static factors of road environment for each of the areas.
