Title:
HYBRID ELECTRIC VEHICLE AND METHOD FOR CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2014/188877
Kind Code:
A1
Abstract:
In the present invention, when the load (requested load) required for the driving of a hybrid electric vehicle (1A) is in a pre-set high-load region and the temperature of an NOx occlusive reducing catalyst (17) is below the lower limit value of activation temperatures, a portion of the drive force of a diesel engine (5) is substituted with drive force from a travel motor (6); when the requested load is in a pre-set low-load region and the temperature of the NOx occlusive reducing catalyst (17) is below the lower limit value, the travel motor (6) is driven by a portion of the drive force of the diesel engine (5) and caused to generate electricity; and when the temperature of the NOx occlusive reducing catalyst (17) is above an upper limit value of activation temperatures, a portion of the drive force of the diesel engine (5) is substituted with drive force from the travel motor (6).
