Vehicle control apparatus

摘要

A vehicle control apparatus computes a fuel consumption decrease or a fuel consumption increase for each of a plurality of travel modes. The vehicle control apparatus includes a control section that calculates an engine efficiency of an engine and an MG-INV efficiency which is a combined efficiency of a motor generator and an inverter. The engine efficiency is calculated based on an engine power and an ideal fuel consumption line. The MG-INV efficiency is calculated based on an MG power. As such, based on the engine efficiency and the MG-INV efficiency, the control section computes the per-unit-electric-power fuel consumption decrease or the per-unit-electric-power fuel consumption increase.
