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. |
