Abstract
In a gear-shift instruction device for the hybrid vehicle that includes an engine that can output power for running, an electric motor (such as a motor-generator and a motor) that can output power for running, a power transmission system that transmits power to a drive wheel and can manually select a gear shift position, and a gear-shift instruction unit that prompts a change of the gear shift position to a driver, modes of the guide for gear shift are different between during electric motor running (EV running) and during hybrid running (HV running) for a same accelerator depression amount and vehicle speed in a state that allows manual gear shift operation (manual gear shift mode). This ensures the compatibility between: improvement in energy efficiency and fuel consumption by the gear shift instruction; and reduction in burden of the driver due to gear shifting based on the gear shift instruction.
