Energy consumption and environment protection have become increasingly important, and thus are drivers for developing energy-saving and environment-friendly vehicles. New energy vehicles^1,2 and hybrid powertrain vehicles^3–5 are the main solutions. However, new energy vehicles have not found an acceptable solution with safety, stability and low cost. The hybrid powertrain vehicle has become a concerned technical solution to reduce energy consumption and pollution emissions.⁶ The hybrid powertrain vehicle has gained research interest as a short- and mid-term solution worldwide.
