NOVELTY - The method involves determining (S20) whether the operation of first high power consumer is performed or not by major load dispersion logic if engine cranking is stopped, when key-on is detected. The operation of first high power consumer is stopped, when working operation of engine is performed. The operability of second high power consumer is determined, and is lower than the first high power consumer. The minor load dispersion logic is stopped and performed in engine stop, when operability of first high power consumer is determined.    USE - Method for controlling load in vehicle for high power consumption apparatus (claimed).    ADVANTAGE - The frequent driving of alternator and frequent charging/discharging of the battery are prevented in the normal operation of the positive temperature co-efficient heater and electrically heated catalyst (EHC). The durability weakening of the alternator and battery is prevented in the driving of the positive temperature co-efficient heater and EHC. The driving of the EHC is performed normally without the durability weakening of the alternator and battery, so that the power consumption of the high power consumption apparatus is reduced. The performance of the catalyst is operated rapidly.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the vehicle for high power consumption apparatus.    DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the process for controlling load in vehicle for high power consumption apparatus. (Drawing includes non-English language text)    Step for driving EHC classified into engine cranking in load best distribution logic (S10)    Step for determining whether the operation of first high power consumer is performed or not by major load dispersion logic (S20)    Step for checking state of driving engine (S40)    Step for checking operability of the positive temperature co-efficient heater (S60)    Step for checking the coolant temperature and outside air temperature (S70)
