System for distributing road surface information, system for collecting and distributing vehicle information, device for transmitting vehicle information and program for controlling vehicle

摘要

A system for distributing road surface information comprising means for sensing numerical information on slipperiness of a road surface; means for sensing positional information of the travelling vehicle; means for transmitting the numerical information and/or positional information from the vehicle; means for collecting the information transmitted by a plurality of vehicles; means for preparing road surface information of a road on the basis of each information; means for distributing the road surface information also to a vehicle other than the vehicle; and means for receiving the distributed road surface information. By changing a parameter of road surface information in a vehicle movement control system such as an ABS or a VSC, the performance of the control can be improved.
