Title:
CONTROL DEVICE AND CONTROL METHOD FOR INTERNAL COMBUSTION ELECTRIC TRANSMISSION TRACTOR TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/000593
Kind Code:
A1
Abstract:
Disclosed in the present invention are a control device and control method for an internal combustion electric transmission tractor transmission system. The control device comprises an internal combustion electric transmission system transmission control unit and an internal combustion electric transmission system, the internal combustion electric transmission system comprising an asynchronous power generator, a power generator converter, an electric motor converter, a brake unit, a DC-DC converter and an asynchronous electric motor. In the present invention, an asynchronous power generation/electric internal combustion electric transmission system is used, such that the reliability of the system can be improved, the maintenance cost can be reduced, and the volume of the transmission system can be reduced, thereby facilitating the optimization of the spatial layout of a whole vehicle. By means of optimizing the design of a controller hardware circuit and a control method therefor, the technical advantages of the asynchronous power generation/electric internal combustion electric transmission system can be brought into full play. By means of joint optimization control of a diesel engine, an asynchronous power generator and an asynchronous electric motor, the utilization rate of fuel oil and the efficiency of a transmission system are improved, which is more energy-saving and environmentally friendly.
