The invention discloses a series mode combustion efficiency control method for a hybrid electric vehicle and a storage medium. When the whole vehicle is in a high-temperature series control mode, thetarget output power is kept unchanged, and the engine speed is increased and the engine output torque is reduced, so that the combustion efficiency reaches the optimal combustion efficiency under thecurrent working condition. The knocking phenomenon of the engine is eliminated by increasing the rotating speed of the engine and reducing the output torque of the engine, so that the combustion efficiency of the engine reaches the optimal combustion efficiency under the current working condition, the output power is kept unchanged, the knocking phenomenon of the engine is eliminated, and deterioration of fuel economy is avoided.
本发明公开了一种混动汽车串联模式燃烧效率控制方法、存储介质,当整车处于高温串联控制模式时,保持目标输出功率不变,同时增大发动机转速和降低发动机输出扭矩,使燃烧效率达到当前工况下的最佳燃烧效率。通过增大发动机转速和降低发动机输出扭矩来消除发动机的爆震现象,从而使发动机的燃烧效率达到当前工况下的最佳燃烧效率,既保证了输出功率不变,又消除了发动机的爆震现象,避免了燃油经济性的恶化。
