Problems solved by technology

[0002] The engine of a car is controlled by an electronic control system. Usually, the driver controls the working state of the engine by stepping on the accelerator. When the vehicle is in a state of non-uniform speed, it is necessary to frequently control the engine state through the accelerator. The accuracy of the accelerator directly affects the fuel injection volume of the engine. And the acceleration of the vehicle, even experienced drivers, it is difficult to control the throttle in the best state, resulting in an increase in fuel consumption, so the present invention

Abstract

The invention discloses an automobile engine fuel-saving control system and a method, wherein the control system comprises an engine ECU, a condition selection controller and a body attitude sensor, the signal output end of the body attitude sensor is connected to the signal input end of the condition selection controller, and the signal output end of the condition selection controller is connected to the engine ECU, the condition selection controller sends a working command to the engine ECU according to a body attitude signal collected by the body attitude sensor so as to control the workingstate of the engine ECU. The fuel-saving control system and method of the automobile engine can realize automatic switching of the engine working conditions, save fuel and reduce consumption.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an automobile engine fuel-saving control system and method. Background technique [0002] The engine of a car is controlled by an electronic control system. Usually, the driver controls the working state of the engine by stepping on the accelerator. When the vehicle is in a state of non-uniform speed, it is necessary to frequently control the engine state through the accelerator. The accuracy of the accelerator directly affects the fuel injection volume of the engine. And the acceleration of vehicle, even experienced driver, it is also difficult to control the accelerator in the best state, resulting in the increase of fuel consumption, so the present invention comes. Contents of the invention [0003] The object of the present invention is to provide an automobile engine fuel-saving control system and method, the automatic selection of the engine working conditions can achieve...
