Abstract

The invention provides an automobile hybrid driving device and a control method thereof, which belong to the technical field of hybrid and solve the problem that the existing hybrid driving device is long in axial length and extremely difficult in layout. The hybrid driving device comprises an engine, a front driving motor, a back driving motor and a storage battery, the engine is connected with the front driving motor through a first clutch, the front driving motor is connected with a front driving shaft through a speed changer, a second clutch is arranged between a front speed changer and the front driving motor, the back driving motor is connected with a back driving shaft through a speed changer, and the front driving motor and the back driving motor are both connected with the storage battery. The control method achieves driving of the whole automobile under different models and recovery of braking energy by judging stored electric quantity of the storage battery, automobile speed signals and acceleration speed signals. The automobile hybrid driving device and the control method are easy to install and lay out, and improve recovery ratio of the braking energy and the whole automobile all-electric range.

Description

technical field [0001] The invention belongs to the technical field of hybrid power, and relates to a vehicle hybrid drive device and a control method thereof. Background technique [0002] Due to the depletion of oil resources and the improvement of public awareness of environmental protection, automobile factories around the world are engaged in the development of new energy vehicles, especially hybrid vehicles. However, at present, hybrid vehicles are mainly mild and medium hybrid vehicles, and strong hybrid vehicles are relatively rare. There are many reasons for this phenomenon. The main reason is that the powertrain system of a strong hybrid vehicle has a complex structure and a large volume, and it is difficult to install and arrange it in the limited space of the vehicle. [0003] ISG is an integrated car starter and generator, which is directly integrated on the engine shaft. ISG integrates motor, modern power electronics, digital signal processing, modern control ...
