METHOD AND SYSTEM FOR CONTROLLING ELECTRICAL POWER FOR VEHICLE AND VEHICLE HAVING THE SYSTEM

摘要

The present invention relates to a method and a system for controlling power generation of a vehicle, and a vehicle having the same which are able to prevent a sudden load change of an engine by appropriately controlling the load of a generator based on battery information, and information of coolant temperature and outside air temperature when starting the engine; to improve the starting feeling of the engine; and to alleviate the NVH (noise, vibration and harshness). An embodiment of the present invention is a control method of the generator generating electric power using rotary power of an engine and comprising: a step of determining if the engine starting is an initial starting or a starting by ISG (idle stop and go); a step of calculating a starting voltage control time (t1) based on the outside air temperature and the coolant temperature when the engine starting is an initial starting; a step of calculating a starting voltage control time (t2) based on the state of charge (SOC) of the battery when the engine starting is a starting by ISG; and a step of controlling the starting voltage during the calculated control time (t1 or t2).
