Claim 0:
1. A non-transitory storage medium for use in an information processing device in a vehicle control system, the storage medium storing:
pieces of positional information each associated with a unique traveling point of traveling points that one or more of a plurality of vehicles have traveled through;
pieces of first cumulative relative frequency distribution information associated with individual vehicle traveling directions, the pieces of first cumulative relative frequency distribution information being related to first data on traveling load amounts of the plurality of vehicles at the traveling points or the traveling load amounts of the plurality of vehicles a traveling time or a traveling distance away from the traveling points;
pieces of second cumulative relative frequency distribution information associated with the individual vehicle traveling directions, the pieces of second cumulative relative frequency distribution information being related to second data on the traveling load amounts of the plurality of vehicles at additional points different from the traveling points the traveling time or the traveling distance away from the traveling points, the additional traveling points identifying where the plurality of vehicles travel to after an elapse of a predetermined maximum communication delay time from the traveling points; and
instructions that are executable by one or more processors and that cause the one or more processors to perform functions comprising:
calculating a predicted value of a traveling load amount of the traveling load amounts for each vehicle of the plurality of vehicles depending on the traveling time or the traveling distance from an arbitrary traveling point of the traveling points or of the additional traveling points based on the pieces of first cumulative relative frequency distribution information and the pieces of second cumulative relative frequency distribution information associated with each individual vehicle traveling direction of the individual vehicle traveling directions at the arbitrary traveling point, and
when a request signal containing a current position and a current traveling direction of a first vehicle of the plurality of vehicles is received from the first vehicle,
setting the current position as the arbitrary traveling point and setting the current traveling direction as a first vehicle traveling direction of the individual vehicle traveling directions;
calculating the predicted value of a first traveling load amount as the traveling load amount depending on the traveling time or the traveling distance away from the arbitrary traveling point based on the pieces of first cumulative relative frequency distribution information associated with the first vehicle traveling direction at the arbitrary traveling point;
calculating the predicted value of a second traveling load amount as the traveling load amount depending on the traveling time or the traveling distance away from the arbitrary traveling point based on the pieces of second cumulative relative frequency distribution information associated with the first vehicle traveling direction at the arbitrary traveling point; and
transmitting the predicted value of the first traveling load amount and the predicted value of the second traveling load amount to the first vehicle,

wherein, at a time of receipt of the predicted value of the first traveling load amount and the predicted value of the second traveling load amount at the first vehicle, the vehicle control system is configured to enable the first vehicle to update the predicted value of the traveling load amount using linear interpolation to account for an additional predicted traveling load used for heating a catalyst device associated with an exhaust passage of an internal combustion engine onboard the first vehicle during a preheating time based on the current position of the first vehicle at the time of receipt, the predicted value of the first traveling load amount, the predicted value of the second traveling load amount and the time of receipt.
