Hybrid technology is currently an effective countermeasure for automobiles to achieve immediate energy saving and emission reduction effects,and hybrid dedicated transmission is a key core component of hybrid vehicles(including plug-in),which directly affects the energy consumption of the vehicle,so the optimization and enhancement of the efficiency is an important topic in the development of hybrid dedicated transmission.To address the issue,based on the hybrid dedicated transmission characteristics of highly integrated mechanical transmission,motor,motor controller and multi-drive mode,three aspects of transmission loss,lubricant viscosity,motor system zero-torque compensation control are researched through theoretical analysis and test.First of all,the distribution of transmission loss is analyzed,and then the direction of efficiency optimization is obtained and experiment is carried out to verify the optimization effect;the different viscosity oil on the efficiency of the hybrid dedicated transmission is analysed,and the actual use of typical conditions for testing and verification is set up;the motor control of direct-drive mode of hybrid dedicated transmission is analysed and tested,revealing the impact of the system efficiency of different control strategies at the motor zero-torque state.Reference and basis for the efficiency improvement of the actual development process of hybrid dedicated transmission are provided.
