In a method for data collection by means of a vehicle fleet and a control center, the control center produces data collection tasks for data collection and transmits at least one of the data collection tasks (6) to at least one vehicle in the vehicle fleet, the vehicles in the vehicle fleet being identifiable by means of vehicle attributes. The control center links each data collection task with an objective, wherein the vehicle attributes of the vehicles logged in to the control center are compared with the objectives of the data collection tasks, after which, if the objective of one of the data collection tasks matches the vehicle attributes of one of the vehicles, the corresponding data collection task is transmitted to the corresponding vehicle, after which a data collection device in the vehicle acquires task-specific data and transmits it to the control center.
