Embodiment Construction

[0026] It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict.

[0027] The current diesel engine or gasoline engine basically uses supercharging technology and is equipped with a supercharger. The supercharger includes a bladeless turbine casing, a turbine working wheel, a first sealing device, a bearing, lubricating oil, a thrust bearing, and a second sealing device. , Compressor casing and compressor and its working wheel, when the supercharger is working, the air and the exhaust gas discharged from the engine enter the supercharger.

[0028] At present, the exhaust gas turbocharging technology is basically used for cars, sport utility vehicles (sport / suburban utility vehicles, SUVs), pickups, light trucks and other models on the market. figure 1 A schematic diagram of a vehicle supercharging structure provided by an embodiment of the present application is shown. see...

Abstract

The invention provides a vehicle control method, a controller and a vehicle, and belongs to the technical field of vehicles. The method is applied to a controller in a vehicle, the controller is connected with a turbocharger and a supercharging compensator of the vehicle, and the turbocharger and the supercharging compensator are both connected to an air inlet pipe of an engine of the vehicle. The method comprises the steps that the current state of the turbocharger is obtained; when the current state of the turbocharger is the working state, the engine rotating speed of the vehicle is obtained; and when the rotating speed of the engine is smaller than the target rotating speed, the supercharging compensator is controlled to input air flow into the air inlet pipe so as to increase the air flow in the air inlet pipe, then a driving source of the turbocharger can be supercharged, and the problem that the driving force of the turbocharger is insufficient is solved. In this way, the supercharging effect of the vehicle can be guaranteed, and the effects of improving the power of the diesel engine and improving the power of the diesel engine can be achieved.

Description

technical field [0001] The present application belongs to the technical field of vehicles, and in particular, relates to a vehicle control method, a controller and a vehicle. Background technique [0002] At present, diesel engines are directly connected to the air filter through the intake pipe. The air filtered by the air filter enters the engine cylinder through the intake pipe. When the engine is running at a low speed, this natural intake method can meet its power. When the engine is running at high speed, the speed of the piston in the cylinder is accelerated, the valve opening time is shortened, and accompanied by air flow fluctuations, it will lead to insufficient intake air, insufficient combustion, affecting the power of the diesel engine, resulting in insufficient power. question. [0003] In the related art, in order to solve this problem, many vehicles have used supercharging technology, such as: exhaust gas turbocharging technology, which uses the exhaust gas ...
