Abstract
A method of controlling a hybrid-electric vehicle includes determining that a slow-down condition of the hybrid-electric vehicle comprises a reduction in speed of the hybrid-electric vehicle that is greater than or equal to a threshold. The method also includes modifying transmission shifting points in a regenerative braking mode to rotate an electric machine of the hybrid-electric vehicle above an engine start limit. The method also includes, in response to receiving an indication of an end of the slow-down condition, causing rotation of the electric machine above the engine start limit to trigger starting an engine of the hybrid-electric vehicle.
