Automobile control method and system and automobile with control system

Abstract

The invention provides an automobile control method which includes the following steps that when an automobile is started or runs, the practical lodes of an automobile are detected; the power and the torque curves of an engine under automobile working conditions corresponding to the practical loads are selected according to the practical loads, wherein different working conditions correspond to different preset power and different torque curves of the engine; the fuel jetting pressure, the jetting moment and the jetting amount are controlled according to the requested torque, power and torque curves of a driver so as to reduce the fuel consumption of the automobile. According to the automobile control method, the automobile can select the engine power and torque curves corresponding to the practical loads according to the practical loads of the automobile, accordingly, the output performance of the engine is determined, and the automobile can run with the minimum fuel consumption rate under different working conditions. Thus, fuel can be saved, in addition, the method can avoid overspeed running when the automobile is in the no-load process or half-load process, and safe running is ensured. The invention further provides a control system of the automobile and the automobile with the control system.

Description

technical field [0001] The invention relates to the technical field of automobile internal combustion engines, in particular to an automobile control method, a control system and an automobile with the control system. Background technique [0002] The development of the automobile industry was accompanied by the development of the internal combustion engine. Usually, when it comes to cars, users are mainly concerned with the performance of the engine, and the performance of the engine is mainly dependent on its settings. With the development of the internal combustion engine, electronic equipment and systems have become an indispensable part of the internal combustion engine. Automatic control of the fuel system through the internal programming of the ECU has become one of the main technologies. [0003] Generally, most internal combustion engines of National III and above use electronically controlled common rail equipment to control fuel injection to meet national emissio...
