A Review on Hybrid Vehicle Powertrain Matching and Integrated Control Based on ECVT

摘要

Powertrain Matching has a greater impact on dynamics, fuel economy, and emissions performance. In order to improve the Hybrid Vehicle efficiency and drive quality, and reduce the pollutions, taking electronic continuously variable transmission (ECVT) as the research object, we comprehensively analyzed the Vehicle Matching Theory, Integrated Control and Intelligent Calibration, and developed a road map for the current and future ECVT technologies: taking the engine power loss rate, fuel utilization, and purification rate of pollutants as the optimization objectives; matching the ECVT, Engine, Motor and Battery with Vehicle's best working status; and establishing the ECVT Matching and Intelligent Calibration and Control Strategy.
