Abstract

The invention discloses a turbocharger control method and device, and a storage medium. The method comprises the steps of determining the required air inflow of an engine when a vehicle decelerates and retracts an accelerator, determining the rotating speed of a turbocharger according to the required air inflow of the engine, and adjusting a waste gate of the turbocharger so as to enable the turbocharger to work at the rotating speed. According to the turbocharger control method and device, and the storage medium provided by the invention, the rotating speed of the turbocharger is determined according to the air inflow demand of the engine, and the rotating speed of the turbocharger is controlled through the linkage between the rotating speed of the turbocharger and the waste gate, so thatthe turbocharger has a certain rotating speed when the accelerator is closed, the turbocharger can quickly reach a target working state when the accelerator is accelerated next time, hysteresis generated when the turbocharger reaches the target working state from the very low rotating speed is reduced, the hysteresis phenomenon generated when the turbocharger is accelerated is reduced on the premise that the cost and oil consumption are not increased, the acceleration responsiveness of the engine is improved, and a power performance of the engine is further improved.

Description

technical field [0001] The invention relates to the field of supercharged engines, in particular to a turbocharger control method, device and storage medium. Background technique [0002] During the operation of the vehicle, the acceleration responsiveness of the engine is very critical to the power performance of the vehicle, and the dynamic performance of the vehicle is related to the driving experience of the user. Therefore, it is necessary to continuously improve the acceleration responsiveness of the engine to meet the increasingly demanding driving requirements of the user. need. [0003] For a supercharged engine, the power performance of a supercharged engine depends on the turbocharger to increase the air intake of the engine to achieve a greater power output. The turbocharger needs to reach a certain speed to increase the intake air of the engine. The role of quantity. The speed of the turbocharger depends on the amount of exhaust gas generated by the engine and...
