Problems solved by technology

[0003] At present, gasoline direct injection (GDI) technology is the most effective method for gasoline engines to organize lean combustion, and the main control chip of the current domestic gasoline direct injection engine (GDI) control system usually adopts 8-bit or 16-bit single-chip microcomputer, As a result, the running speed of the program is slow, and the main control chip cannot respond to changes in the vehicle environment and engine operating conditions in a timely manner, which cannot meet the needs of vehicle safety and engine precise control when the vehicle is moving at high speed, and limits the economy of the vehicle. , comfort and safety are further improved, and its emissions cannot meet increasingly stringent emission standards
Some engine electronic control units cannot work stably, reliably and for a long time in harsh environments and cabins with many sources of electromagnetic interference

Abstract

The invention provides a control system of a direct injection engine in a gasoline cylinder of an automobile and the automobile. The control system comprises multiple engine and automobile signal processing circuits, multiple engine actuating unit driving circuits and an engine main controller. The engine and automobile signal processing circuits are used for processing a received automobile signal. The engine actuating unit driving circuits are used for carrying out driving control on engine actuating units according to control orders. The engine main controller comprises multiple signal transmission interfaces and multiple order control interfaces. The signal transmission interfaces are connected with the automobile signal processing circuits correspondingly in a one-to-one mode and the order control interfaces are connected with the engine actuating unit driving circuits correspondingly in a one-to-one mode. The engine main controller is used for generating the control order. The control system can accurately regulate the engine in time, so that the engine is placed in the optimal working state, a gasoline combustion process is full and the power output by the engine is more powerful.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a control system of a gasoline in-cylinder direct injection engine of a vehicle and the vehicle. Background technique [0002] Gasoline direct injection engine (GDI) has been widely developed due to its advantages of high combustion efficiency. As the control system of direct injection engine (GDI), such as the engine controller is the key to control the normal operation of the engine, and its work must meet the requirements of the automotive control system. Extremely high real-time requirements can meet harsh and drastically changing environmental requirements, and its design must have a high degree of flexibility and reliability. [0003] At present, gasoline direct injection (GDI) technology is the most effective method for gasoline engines to organize lean combustion, and the main control chip of the current domestic gasoline direct injection engine (GDI) con...
