A vehicle includes an engine, a power source, and a motor. The power source outputs electrical energy in accordance with an actual state of charge, and the motor generates electrical energy when provided with torque from the engine. A position sensor generates a route signal representing drive cycle data between a present location of the vehicle and a selected destination. A controller determines a reference state of charge of the power source at the present location from the drive cycle data and commands the engine to charge the power source if the actual state of charge is below the reference state of charge determined for the present location. A method includes receiving the selected destination, generating the route signal, determining the reference state of charge from the drive cycle data, and commanding the engine to charge the power source in accordance with the reference state of charge.
