Document Type and Number:
WIPO Patent Application WO/2019/206227
Kind Code:
A1
Abstract:
The present application provides a design method and a control strategy for a dual-power hybrid system, belonging to the technical field of traditional automobile, hybrid electric vehicle, new energy automobile power assembly design and manufacture. Two motors are used to combine with a two-shift or a multi-shift gear set to form a pure electric dual-power system, so as to realize a stepless shift with alternate relay and unpowered interruption. The motors are enabled to regulate speed in a high-efficiency area within a small range, by means of a switch between the multi-shift gear set, to obtain a stepless speed change that has a high speed ratio range, and the power performance, the economical efficiency and the comfortability are all thus improved. The two motors can be a motor with adjustable speed or two motors with adjustable speed to complete speed changing and gear shifting, the power source thereof can also be a dual-engine, or a motor plus an engine, which are combined into a traditional engine dual-power system or a hybrid system, respectively.
