Series mode combustion efficiency control method for hybrid electric vehicle and storage medium

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of automobile control, and specifically refers to a method for controlling the combustion efficiency of a series mode of a hybrid automobile and a storage medium. Background technique [0002] With people's demand for lower fuel consumption and environmental protection, the market share of hybrid vehicles is increasing. Since the motor, engine and gearbox are arranged in the cabin of the hybrid car at the same time, the layout of the cabin is very compact, and the heat dissipation conditions are worse than those of traditional cars. If the vehicle runs in a high-temperature environment for a long time, the temperature of the engine room will rise, and the water temperature and intake air temperature of the engine will increase. Since the engine series power generation mode of hybrid vehicles generally operates in the best efficiency zone to ensure the best economy , but in the optimum efficiency zone, the e...

Problems solved by technology

If the vehicle runs in a high-temperature environment for a long time, the temperature of the engine room will rise, and the water temperature and intake air temperature of the engine will increase. Since the engine series power generation mode of hybrid vehicles generally operates in the best efficiency zone to ensure the best economy , but in the optimum efficiency zone, the engine is prone to knocking at high temperatures, which reduces the combustion efficiency of the engine, resulting in deterioration of fuel consumption and emissions. At the same time, it will cause deterioration of the cabin temperature field and affect the safety of the vehicle
