Clutch starting recognition and engine auxiliary control system for manual-gear automobile

Abstract

The invention provides a clutch starting recognition and engine auxiliary control system for a manual-gear automobile. The clutch starting recognition and engine auxiliary control system comprises a signal acquisition unit, a signal processing circuit, an engine controller and a driving control circuit, wherein the signal acquisition unit comprises a signal acquisition module for acquiring various signal inputs; the signal processing circuit is used for converting various acquired analog signals into digital signals; the engine controller is used for judging according to the digital signals after processing so as to recognize whether the current clutch is at a starting working condition; if the clutch is at the starting working condition, an idling spark advance angle capable of increasing the torque reserve of an engine and electronic throttle opening are calculated; the driving control circuit is used for outputting a control signal and controlling an automobile ignition coil and the electronic throttle opening so as to improve the current torque reserve of the engine. According to the clutch starting recognition and engine auxiliary control system, higher torque reserve can be achieved during clutch starting of the automobile, much dropping of the rotating speed of the engine or even flameout of the engine is prevented, and the disadvantage of easy flameout during starting is overcome.

Description

technical field [0001] The invention belongs to the technical field of engine control, and in particular relates to a clutch start recognition and engine auxiliary control system of a manual transmission automobile. Background technique [0002] In the development process of automobile products, drivability, as one of the important indicators for evaluating automobile performance, is increasingly valued by consumers, and the clutch starting condition, as one of the most frequently used operations, has a significant impact on drivability. important. The inventor of the present invention has found through research that in order to improve the fuel economy and emission performance of automobiles, reducing the engine target idle speed is a common method selected by automobile manufacturers; but at the same time, due to the reduction of the engine target speed, the engine reserve Torque is also reduced, making it easier for the driver to stall when the clutch starts.
