Engine idle speed compensation method and device, electronic equipment and storage medium

Abstract

The invention relates to an engine idle speed compensation method and device, electronic equipment and a storage medium. The method comprises the steps that the water temperature of a vehicle engine is collected; when the water temperature is larger than or equal to the preset temperature threshold value and the engine is at the idle speed, the running state of the vehicle air conditioner is determined; under the condition that the running state is the starting state, the working power of a vehicle air conditioner is obtained, a first target rotating speed compensation value corresponding to the working power is obtained, and idle speed compensation is conducted on an engine according to the first target rotating speed compensation value; under the condition that the running state is a closed state, determining target electric equipment in an open state, obtaining a first rotating speed compensation value corresponding to the target electric equipment, obtaining an SOC value of a storage battery of the vehicle, and obtaining a second rotating speed compensation value corresponding to the SOC value, and a second target rotating speed compensation value is calculated according to the first rotating speed compensation value and the second rotating speed compensation value, and idle speed compensation is conducted on the engine according to the second target rotating speed compensation value.

Description

technical field [0001] The present disclosure relates to the field of engine control, and relates to a method, device, electronic equipment and storage medium for engine idle speed compensation. Background technique [0002] Engine idle speed is one of the engine operating conditions. The idle speed condition refers to the state of the engine running without load (i.e. running in neutral). The engine idle speed performance has a great impact on emissions, fuel consumption and comfort. Therefore, the engine idle speed performance is the key to evaluating An important indicator of engine performance. [0003] The existing idle speed control is to calculate the engine speed compensation value through the engine water temperature and atmospheric pressure, so as to compensate the engine idle speed. However, in the case of a large vehicle power consumption, the engine load will increase, and the engine The jitter is large, that is to say, the existing idle speed compensation meth...

Problems solved by technology

[0003] The existing idle speed control is to calculate the engine speed compensation value through the engine water temperature and atmospheric pressure, so as to compensate the engine idle speed. In the case of a large amount, the load on the engine will increase and the engine will vibrate greatly. That is to say, the existing idle speed compensation method cannot accurately compensate the engine.

[0004]The existing idle speed control does not include the power consumption of the whole vehicle into the scope of compensation, resulting in an increase in engine load when the power consumption is large, resulting in increased engine vibration or even flameout, causing customer complain
