Abstract

The invention is a power output switching method and control system of power assembly of mixed power saloon car. It can switch the power output and manage system energy, and according to state switching boundary value and result judgment of data collection, makes the power assembly switch to the states such as reclaiming plugging energy; charging accumulator by engine; electric driving; mixed driving; engine driving; etc to make coordination treatment. Its control system includes main chip, as well as switch quantity conditioning circuit, analogue quantity conditioning circuit, pulse signal conditioning circuit, CAN bus interface, D / A converting circuit, drive isolating circuit, etc, where they are all connected with the main chip. It can make the output torque realize fast smooth switch in a large range, and heightens the energy using efficiency.

Description

technical field [0001] The invention belongs to the technical field of hybrid car power assembly control, and in particular relates to a power output switching method of a hybrid electric car power assembly and a multi-energy power assembly control system. Background technique [0002] With its advantages of low energy consumption and low emission, the hybrid car has become a hot spot in the research of future automobile technology. The research on the powertrain control system of hybrid electric vehicles is still in its infancy in China, and there is still no mature technology. The multi-energy control system of a hybrid car is a relatively complex system, which needs to coordinate the relationship between the engine as the power source and the battery motor system, and also communicate with the AMT (electronically controlled mechanical transmission) control system to provide The signals required for gear shift control and the combination and disengagement of the control g...
