Problems solved by technology
Toyota's single-mode hybrid system uses a single planetary row as the power coupling mechanism, and the powertrain layout is relatively simple, but power circulation occurs under high-speed conditions, resulting in multiple energy conversion losses
In order to overcome the power cycle phenomenon of Toyota's single-mode hybrid system under high-speed conditions, the general-purpose dual-mode hybrid system increases the number of power split mechanical points by increasing the number of planetary rows and multiple clutches, thereby reducing the high-speed The probability of power cycling under working conditions, but this brings about an increase in the complexity and control difficulty of the entire power distribution mechanism

Description
technical field [0001] The invention relates to the technical field of a drive system of a hybrid electric vehicle, in particular to a drive system configuration of a dual-planetary double-mode hybrid electric vehicle and the vehicle. Background technique [0002] With the intensification of the energy crisis and the deterioration of the ecological environment, energy conservation and environmental protection have become the two major themes of the current automotive industry, so various new energy vehicles have emerged as the times require. At present, fuel cell vehicles and pure electric vehicles are restricted by problems such as cost, battery life, and battery electrolyte pollution, and cannot be widely promoted for the time being. Hybrid vehicles rely on their relatively mature technology, good power and fuel economy. It has become the best choice for current auto manufacturers. [0003] At present, the hybrid power system can be divided into three types: series, paral...
