Abstract
A fleet operation management system for a vehicle traveling on a predetermined travel route comprises: a storage unit () which stores travel route information including the position, height and surface resistance of the vehicle's travel route; a speed prediction unit () which predicts future change in the speed of the vehicle coasting on the travel route based on the current position, the current speed, and the travel route information; and an operation timing calculation unit () which judges which of acceleration, deceleration and coasting should be performed at the current position based on the change in the coasting speed so that the vehicle speed after the lapse of a predetermined time will be within a predetermined range. This configuration makes it possible to properly judge which of the acceleration, the deceleration and the coasting should be performed on the vehicle's travel route from the viewpoint of fuel-efficient operation.
