US Patent 11370451 Information providing system and information providing method

A server includes a storage device that stores history information indicating a history of a state of a vehicle, and a controller that performs a process using the history information. The controller makes a first determination of whether or not a vehicle load exceeds a first load. For the vehicle for which it has been determined that the vehicle load is higher than the first load in the first determination, the controller makes a second determination of whether or not an environmental load is higher than a second load. When it is determined that the environmental load is higher than the second load in the second determination, the controller outputs an area change request requesting a change of the dispatch area of the vehicle to another dispatch area lower in the environmental load than a current dispatch area.
