Problems solved by technology

However, at present, the matching of the coupling between the electronic supercharger and the turbocharger is a difficult problem. If the two are not well matched, not only will the effect of 1+1>2 not be obtained, but the driving experience may be frustrated, thereby reducing the driver's driving experience

Abstract

The invention provides a hybrid supercharging system, a control method of the hybrid supercharging system, and a vehicle. The system comprises an electronic supercharger, an exhaust gas turbosupercharger and a controller, wherein the controller is separately connected with the electronic supercharger and the exhaust gas turbosupercharger, and is used for obtaining the accelerator pedal change rate of the vehicle; when the accelerator pedal change rate is larger than a first preset change rate and the allowed start-up conditions of the electronic supercharger are met, the electronic supercharger is controlled by the controller to start up, and an engine is supercharged at the same time by the electronic supercharger and the exhaust gas turbosupercharger; and when the accelerator pedal change rate is smaller than the first preset change rate, the electronic supercharger is controlled by the controller to shut down, and the engine is supercharged by the exhaust gas turbosupercharger. Through the adoption of the hybrid supercharging system disclosed by the invention, the coupling problem of the electronic supercharger and the exhaust gas turbosupercharger is solved, and the maximum torque and the acceleration response of the engine are increased, so that the acceleration property of the whole vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a hybrid supercharging system, a control method thereof, and a vehicle. Background technique [0002] Environmental issues, energy crisis, stringent emission and fuel consumption regulations have brought severe challenges to the internal combustion engine industry. Reducing fuel consumption and reducing emissions are the two core issues at present. [0003] At present, in Europe and China, miniaturization of supercharging is used as a method of saving energy and reducing consumption of internal combustion engines, so the displacement of internal combustion engines is getting smaller and smaller, and the supercharging pressure is getting higher and higher. Most of the superchargers currently used are exhaust gas turbochargers. When accelerating, it is necessary to use the high-temperature and high-pressure exhaust gas discharged from the current several cycles to drive the tu...
