The invention relates to a hybrid power system with a series-parallel connection structure, and particularly discloses a low-cost parallel shaft type hybrid power system and a control method thereof.The hybrid power system comprises an engine (1), a first clutch (2), a first gear set (3), an accessory drive gear set (4), an accessory drive device (5), a second clutch (6), a low pressure mechanical accessory (7), a second gear set (8), a rear axle main reducing gear (9), a first motor (12), a second motor (10), a power battery (13) and an inverter (14). The parallel shaft type hybrid power system is applied to a vertically arranged rear drive hybrid electric vehicle, and has the advantages that structure is compact and control is simple, a low-pressure mechanical accessory of a conventional fuel vehicle can be used, the overall vehicle cost of the hybrid electric vehicle and the fuel consumption of the whole vehicle are reduced, a clutch C1 can be separated when the engine is not in work, and the engine is prevented from being dragged.
Description
technical field [0001] The invention relates to the technical field of automobile power systems, in particular to a series-parallel hybrid power system. Background technique [0002] In order to overcome the problems of short driving range and limited long-distance driving of pure electric vehicles, hybrid technology has become an inevitable choice for major vehicle manufacturers to cope with increasingly stringent fuel consumption limits and emission regulations. There are three configurations of the hybrid system: series, parallel, and hybrid, and the hybrid is further divided into series-parallel and power-split hybrid. The tandem configuration is simple in structure, but has low energy conversion efficiency and poor dynamic performance under high-speed conditions. The parallel configuration is powerful, but since there is only one motor, it cannot drive the vehicle while charging. The power-split hybrid configuration has a good fuel-saving effect, but the structure and...
