Abstract
A fuel-saving drive recommendation system is mounted on a vehicle that includes a step-gear automatic transmission of which a gear is shifted in response to a gear instruction signal. The fuel-saving drive recommendation system calculates a required driving force based on an amount by which an output operating component is operated by a driver and a gear of the automatic transmission, makes determination for fuel-saving drive for the vehicle based on the required driving force and notifies the determination result. The fuel-saving drive recommendation system calculates a required driving force for performing output control on an engine and a required driving force for determining whether it is a fuel-saving drive state. A determination gear signal different from the gear instruction signal is used when the determination required driving force is calculated, and is changed to coincide with the gear instruction signal that has been changed.
