Abstract
A coasting driving control method and system for a vehicle may determine virtual engine RPM for a current driving state using engine RPM, vehicle speed, and gear stage information by a controller when coasting is started with the clutch in the neutral position and outputs a downshifting instruction signal for a gear stage by the controller when the virtual engine RPM is less than a coasting engine RPM which is greater than an idling RPM by a predetermined value.
