Abstract
Managing a vehicle body including computing an efficiency value of a monitoring target, the monitoring target being the power train or a part or a subsystem of the power train, on the basis of information about the vehicle body, the information being sensed by a sensor provided to the vehicle body. An output terminal that outputs the efficiency value of the monitoring target. Determining whether a load parameter is larger than a load determination value set in advance, and computing the efficiency value of the monitoring target on the basis of input energy and output energy of the monitoring target on condition that the load parameter be larger than the load determination value, and recording the computed efficiency value of the monitoring target.
