To achieve data distribution control for satisfying communication delay required by an application when distributing a message from a center to a vehicle via a network.SOLUTION: A message distribution control system includes a vehicle data generation device 210 and a telematics center 100. The vehicle data generation device includes: a probe information generation unit 212 for collecting probe information of a vehicle and performing predetermined processing; an event detection unit 213 for detecting an event on the basis of probe information; and a vehicle data transmission unit 214 for transmitting probe information with predetermined processing performed therein and detected event information to the telematics center as vehicle data information. The telematics center includes: a vehicle data information database 122 for storing vehicle data information; an event occurrence information database 123 for storing event information; an encounter time calculation unit 114 for calculating an encounter time with respect to an event for each vehicle; and a message distribution unit for preferentially distributing a message to a vehicle with a shorter encounter time.SELECTED DRAWING: Figure 1
