The invention discloses a torque distribution method, a system and equipment of a hybrid electric vehicle and a storage medium. The method comprises the steps that the request torque of a driver is obtained; if it is detected that an engine does not work in the efficient area, the output torque of the engine is increased so that the engine can work in the efficient area; and if it is detected thata vehicle battery needs to be charged, torque used for charging the vehicle battery is determined according to the request torque and the output torque. The problems that when an engine of a traditional oil consumption automobile works under different working conditions, the working efficiency of an engine system is low, the oil consumption of the whole automobile is easily increased, and the NVHperformance of the whole automobile is poor are solved, the oil consumption of the whole automobile is reduced, the fuel cost is saved, and the NVH performance of the whole automobile is improved.
Description
technical field [0001] The present invention relates to the technical field of vehicle control, in particular to a torque distribution method, system, device and storage medium of a hybrid electric vehicle. Background technique [0002] Cars are "machines that change the world" and the wheels that drive social progress. Cars have become an indispensable part of our daily lives, bringing great convenience to our life and work travel. [0003] Traditional fuel-efficient vehicles use the engine and clutch to control vehicle start-up and gear shifting. When the engine is started at low temperature, due to insufficient gasoline combustion, the fuel consumption of the engine is relatively high during low-temperature start-up, and the vibration and noise are obvious, making the vehicle's NVH ( Noise, Vibration, Harshness; that is, noise, vibration, and harshness) have poor performance; when the engine is in a static idle process, it needs continuous fuel consumption, and at this ti...
