GENERAL MOTORS DEVELOPS TWO- MODE HYBRID POWERTRAIN USING MODEL-BASED DESIGN

摘要

The Two-Mode Hybrid powertrain is part of GM's hybrid program, with multiple hybrid and electric vehicle technologies designed to meet diverse driving patterns and needs. Created to optimise fuel efficiency in both city and highway driving, the Two-Mode Hybrid powertrain combines a conventional engine with two 60kW electric motors integrated into an automatic transmission, as well as using new components such as battery and power electronics.rnUsing maths and simulation-based software tools, such as Matlab and Simulink, GM designed the powertrain prototype within nine months, shaving 24 months off the expected development time.
