Problems solved by technology

[0007] However, in a conventional vehicle, instead of interconnecting the power generation of the alternator and the power generation of the turbocharger to perform control
In addition, the process in conventional vehicles is not to establish the generation load of each according to the generation efficiency of each
Therefore, although a conventional vehicle has an alternator and a turbocharger, it cannot achieve maximum efficiency from both in generating electricity

Embodiment Construction

[0033] figure 1 The configuration of the first embodiment of the present invention is shown. figure 1 The system shown in has a motor-assisted turbocharger (MAT) 10 . The MAT 10 has a compressor disposed in an intake passage of the internal combustion engine, a turbine disposed in an exhaust passage, and an electric motor providing motive power to these components (none of which are shown).

[0034] In the MAT10, in addition to being able to rotate the turbine and the compressor using exhaust energy, it is also possible to rotate the turbine and / or the compressor using an electric motor as a drive source. When the turbine and compressor are spinning, the MAT10 enables the electric motor to act as a generator, the energy of its rotation being converted into electricity.

[0035] A battery 14 is connected to the MAT 10 via an inverter 12 . A motor control device 16 is connected to the inverter 12 . Motor control device 16 may apply a signal having a desired conduction mode to ...

Abstract

A vehicle has an alternator (20) and a motor-assisted turbocharger (MAT) (10). A electrical generation amount control apparatus (24) calculates the electrical generation efficiency ?m of the MAT (10) and the electrical generation efficiency ?a of the alternator (20) and, based on these values, calculates the electrical generation instruction amount 1 to be demanded of the MAT (10) and the electrical generation instruction amount 2 to be demanded of the alternator (20). Of the electrical generation instruction amount 1 and the electrical generation instruction amount (2) are calculated to give priority in electrical generation to which of the MAT 10 and the alternator (20) has the higher electrical generation efficiency.

Description

technical field [0001] The present invention relates to a power generation control device and a control method in a vehicle, and particularly to a power generation control device suitable for controlling power generation in a vehicle including a turbocharger having a power generation function. Background technique [0002] As disclosed in Japanese Patent Application Publication No. JP-A-H11-324688, there is known a vehicle including a turbocharger having a power generating function. When the vehicle is decelerating, the turbocharger acts as a generator to perform regeneration of electrical energy. [0003] The aforementioned vehicle can store energy to be consumed during deceleration, and convert this energy into electrical energy. Such a vehicle has improved energy efficiency such that the energy efficiency is higher than that of a vehicle in which the turbocharger does not perform regeneration. [0004] An alternator that generates electric power as energy using output t...
