Abstract
An engine operation control apparatus and engine operation control method of a vehicle are provided. The engine operation control apparatus includes a coolant temperature sensor that detects a coolant temperature of a coolant line which passes through an engine. Further, the apparatus includes first and second maps in which corresponding engine operating points are mapped to a vehicle speed, a gear stage, a driver requesting torque, and an electric field load amount of the vehicle. A controller determines a candidate operating point using any one of the first and second maps based on a comparison between the coolant temperature and a predetermined threshold value and determines an optimal operating point of the engine using the candidate operating point.
