Power control system and control method for double-motor hybrid vehicle

Abstract

The invention provides a power control system. In the power control system, a second motor controller outputs at leas one electric signal for controlling the power output of at least one of a first motor, a second motor and an engine to at least one of the first motor controller, the second motor controller and an engine controller according to a received electric signal indicating the battery capacity SOC value and an electric signal indicating required driving power. In a power control method provided by the invention, the second motor controller controls the power output of at least one ofthe first motor, the second motor and the engine according to the received electric signal indicating the battery capacity SOC value and the electric signal indicating required driving power. The power control system and the power control method reduce development cost and contribute to the fuel economy and emission reduction of the whole vehicle.

Description

Technical field [0001] The invention relates to an automobile power system, and in particular to a power control system and a control method for a dual-motor hybrid electric vehicle. Background technique [0002] At present, due to people's increasing emphasis on environmental protection and the effective and rational use of energy, gasoline-electric hybrid dual-motor hybrid vehicles with high efficiency, energy saving, and environmental protection models have the advantages of low emissions of electric vehicles and high specific energy of internal combustion engine vehicles. It has become a development trend in the automobile industry. Since the 1990s, major automobile companies in Japan, the United States, and Europe have begun to develop hybrid vehicles. In China, the government, scientific research institutions, universities and automobile companies have begun to pay attention to the development and research of dual-motor hybrid vehicles. [0003] The power system of e...
