Abstract

A method of controlling an engine and a transmission of a vehicle, which is a hybrid vehicle, includes the following steps that are carried out by a controller: determining whether the vehicle is under NCC (Neutral Coasting Control), determining whether an engine RPM reaches an engine RPM control point if it is determined that the NCC is in effect, determining an RPM and a gear stage of a vehicle transmission if it is determined that the engine RPM has reached the engine RPM control point, determining an engine target RPM of the vehicle, determining whether the engine RPM has reached a mild hybrid starter & generator (MHSG) control point, and controlling the MHSG according to a condition if it is determined that the engine RPM has reached the MHSG control point.
