Automobile quick starting method, device and equipment and storage medium

Abstract

The invention discloses an automobile quick starting method, device and equipment and a storage medium. The automobile quick starting method comprises the steps that the current shutdown phase of an engine of an automobile is obtained, wherein the shutdown phase comprises a first shutdown phase stored in a first electronic control unit of the automobile and a second shutdown phase stored in a second electronic control unit of the automobile; whether a difference value between the first shutdown phase and the second shutdown phase is within a preset threshold range or not is judged; and if the difference value is within the preset threshold value range, the first shutdown phase or the second shutdown phase serves as a target phase of the engine to complete synchronization of a target crankshaft signal. Whether the current shutdown phases stored in two electronic control units meet the preset conditions or not is judged, whether the current shutdown phases stored in the two electronic control units are directly used for starting the engine of the automobile or not is judged, quick starting of the engine can be achieved, and the time consumed for starting synchronous identification of the engine of the automobile is shortened.

Description

technical field [0001] Embodiments of the present invention relate to automobile control technology, and in particular to a method, device, equipment and storage medium for quick starting of an automobile. Background technique [0002] The phase of a car engine refers to the angle at which the crankshaft of the engine is currently at. The synchronous recognition of the crankshaft and camshaft signals of the engine during the starting process of the automobile engine is a key factor in determining the starting performance of the engine in the engine control. [0003] The automotive electronic controller determines the phase of the engine according to the received crankshaft signal and cam signal, and can perform timing control such as fuel injection and ignition in sequence according to the defined cylinder sequence after synchronous identification. A common practice is to complete timing synchronization and pre-injection by reading the stored memory value of the last phase ...

AI Technical Summary

Problems solved by technology

[0004] For the above method, it is necessary to judge the crankshaft signal and camshaft signal to verify the accuracy of the shutdown phase storage to judge whether to perform ignition. If the memory phase is judged incorrectly, it will cause an increase in exhaust hydrocarbon emissions and waste of fuel.

In order to accurately identify the engine synchronization information, the engine needs to be dragged by the starter to form a complete cycle of 360 ° crankshaft signal, resulting in a waste of start-up time
