  • Patent number: 9139106
    Abstract: Provided is a method of controlling an electric vehicle capable of preferably performing a regenerative control when a plurality of forward driving ranges are shifted to each other. During travelling on a downhill road, the vehicle executes a downhill regenerative control for adjusting the regenerative amount of an electric motor so that acceleration obtained when an accelerator is closed becomes a downhill acceleration according to a road surface slope. The vehicle also executes an acceleration increase control in which the downhill acceleration obtained when the forward driving ranges are shifted from a second forward driving range to a first forward driving range during travelling on the downhill road is at least temporarily set to an acceleration exceeding the downhill acceleration obtained on the assumption that the vehicle continuously travels on the same road surface slope as that of the currently travelling downhill road in the first forward driving range.
