Vehicle control unit for the generation of electric power and control system for the generation of electrical power, which is equipped with the device

摘要

An electric power generation controller (40) is mounted in a motor vehicle and predicts an operating point of an internal combustion engine (10) for the future based on lane information supplied from a navigation system (30) mounted in the motor vehicle is. The apparatus further predicts an increased amount of fuel consumption caused by the electric power generation of an alternator (20) based on the predicted operating point of the internal combustion engine (10). The apparatus sets a reference value of an electric power economy index, which is an amount of fuel consumption per electric power generation. When driving the motor vehicle on a route, the apparatus sequentially predicts the operating point of the internal combustion engine (10) and controls the alternator (20) in such a manner that the current electric power economy index becomes equal to a reference based on the operating point of the internal combustion engine (FIG. 10), which was predicted.
