Distributed hybrid power system of heavy vehicle and vehicle

Abstract

The invention discloses a distributed hybrid power system of a heavy vehicle and a vehicle. The power system comprises a power module, a driving module, an energy storage module and a whole vehicle controller, wherein the power module comprises one or more auxiliary power units used for providing power for an electric power system of the heavy vehicle; the driving module comprises a plurality of driving units; each driving unit is used for directly driving one or more driving axles of the heavy vehicle or directly driving a vehicle wheel of the heavy vehicle to run; the energy storage module is used for storing energy; the whole vehicle controller is connected with the power module, the driving module and the energy storage module and used for controlling whether the driving units are started or not and controlling outputting of the driving units to control the driving state of the heavy vehicle. The distributed hybrid power system of the heavy vehicle and the vehicle have the following advantages that the auxiliary power units are adopted for being electrically connected with the driving units through the distributed system, and a traditional mechanical power transmission system of an engine and the driving axles is omitted, so that the auxiliary power units and the driving units are flexibly arranged on the heavy vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a distributed hybrid power system of a heavy vehicle and the vehicle. Background technique [0002] With the increasingly severe energy crisis and global warming, energy conservation and emission reduction has become an urgent task for the global automotive industry, and new energy vehicles have therefore developed rapidly. How to combine the engine, generator, drive motor and energy storage system (including power battery, super capacitor or composite energy storage system, etc.) Hybrid and other configurations. In the series configuration, the auxiliary power unit (APU) is composed of the engine, shock absorber and generator (including the generator controller, the same below), and there is only electrical connection between the APU unit and the driving motor (including the controller), without The mechanical connection enables the APU unit and drive motor to be arranged ind...

AI Technical Summary

Problems solved by technology

A single large engine + generator often has a relatively large weight and height, and it is difficult to arrange it on the vehicle, which will affect the height of the bodywork and the center of gravity
