Description

Technical field

[0001] The invention relates to a control method of a power system of a hybrid electric vehicle, in particular to a "dual parameter" control method for the braking and deceleration process of a hybrid electric vehicle motor. Background technique

[0002] With the increasingly prominent global environmental and energy issues, the development of new vehicles with low emissions and low fuel consumption has become the primary task of today's automotive industry. Hybrid electric vehicle technology avoids the shortcomings of pure electric vehicles in battery technology and energy infrastructure. It is a good solution to current problems and has become a hot spot in international automotive research and development today.

[0003] The use of electric motors to generate power to recover braking energy is one of the main ways to save energy in hybrid vehicles. At present, the intensity of the braking energy recovered by the electric motor is determined by the braking inten...
