Abstract
When an accelerator is put in an OFF state to decelerate a vehicle and perform inertia travel with supply of fuel being cut off, measurement of an accelerator OFF lapse time is started. When a travel speed falls down to be lower than a pre-stop speed, a measured lapse time is stored in a memory, with the measurement of the lapse time being further continued. After finishing a travel of a downward slope, the travel speed is reduced to fall down to the pre-stop speed again, a lapse time continuously measured up to that time is updated in the memory. When the travel speed falls to a stop speed, the measurement of the lapse time is finished and the continuously-measured lapse time is determined as a required stop time of the vehicle. As the required stop time increases, driving is diagnosed as being fuel-efficient.
