Abstract

Depression of an accelerator pedal by a vehicle operator in an operating condition in which fuel economy is deteriorated, is restrained. An actual opening degree of the accelerator pedal and a reference guide value of the accelerator pedal opening degree which allows a vehicle to accomplish both acceleration performance and fuel economy performance in a current operating condition are indicated in a display section together. In a case where a current gear ratio of a transmission is deviated from an optimal gear ratio of the transmission which is determined based on an operating condition of the vehicle, the reference guide value is changed such that engine output of the vehicle is decreased.
