Problems solved by technology

[0005] Because when the idle ignition angle of the engine is equal to the optimum ignition angle, the fuel combustion efficiency of the engine at idle is the highest, while the idle ignition angle of the engine is not equal to the optimum ignition angle but equal to the torque reserve ignition in the electrical load work process of the prior art Therefore, it reduces the fuel combustion efficiency of the engine at idle speed and increases the fuel consumption

Embodiment 1

[0058] The embodiment of the present invention provides a method for controlling the idle speed of the engine, see figure 1 , the method includes:

[0059] Step 101: receiving an opening request of an electrical load;

[0060] Step 102: Control the electrical load to work, and during the electrical load work, adjust the idle ignition angle of the engine to the optimum ignition angle, and adjust the intake air volume of the throttle to increase the actual speed of the engine until the actual engine speed is reached. When the rotation speed is equal to the first target idle speed, stop adjusting the intake air volume of the throttle valve;

[0061] Step 103: Receive the shutdown request of the electrical load;

[0062] Step 104: Control the electrical load to stop working, adjust the idle ignition angle of the engine to the optimum ignition angle, and reduce the intake air volume of the throttle to reduce the actual speed of the engine until the actual speed of the engine is e...

Embodiment 2

[0080] The embodiment of the present invention provides a method for controlling the idle speed of the engine, see figure 2 , the method includes:

[0081] Step 201: the ECU receives a request to turn on the electrical load;

[0082] Wherein, when the user wants to turn on the electrical load, the user may submit an opening request to the ECU through the switch of the electrical load. When the electrical load is power steering, the preset steering angle for turning on the power steering can be set, and when the ECU detects that the steering angle of the power steering is equal to the preset steering angle, it is determined that the user needs to turn on the power steering. Preferably, the difference between the preset steering angle and the maximum steering angle of the power steering is as large as possible, but the preset steering angle cannot be set smaller, so as to avoid misoperation of turning on the power steering due to slight adjustment of the steering wheel. For e...

Embodiment 3

[0119] see Figure 7 , an embodiment of the present invention provides a device for controlling the idle speed of an engine, the device comprising:

[0120] The first receiving module 301 is configured to receive an opening request of an electrical load;

[0121] The first adjustment module 302 is used to control the electrical load operation, and adjust the idle ignition angle of the engine to the optimal ignition angle during the electrical load operation process, and adjust the intake air volume of the throttle to increase the actual speed of the engine , stop adjusting the intake air volume of the throttle until the actual speed of the engine is equal to the first target idle speed;

[0122] The second receiving module 303 is configured to receive the shutdown request of the electrical load;

[0123]The second adjustment module 304 is used to control the electrical load to stop working, adjust the idle ignition angle of the engine to the optimum ignition angle, and reduc...

Abstract

The invention discloses a method and equipment for controlling the idle speed of an engine, and belongs to the field of automotive electronic control. The method includes: receiving an opening request of the electrical load; controlling the operation of the electrical load, and during the operation of the electrical load, adjusting the idle ignition angle of the engine to the optimal ignition angle, and adjusting the air intake volume of the throttle to increase the actual speed until the actual speed of the engine is equal to the first target idle speed, stop adjusting the intake air volume of the throttle; receive the shutdown request of the electrical load; control the electrical load to stop working, adjust the idle ignition angle of the engine to the optimal ignition angle, and reduce Small the air intake volume of the throttle valve to reduce the actual engine speed, and stop reducing the air intake volume of the throttle valve until the actual engine speed is equal to the second target idle speed, and the second target idle speed is less than or equal to the first target idle speed. The invention ensures the highest fuel combustion efficiency when the engine is idling and reduces fuel consumption.

Description

technical field [0001] The invention relates to the field of automobile electronic control, in particular to a method and equipment for controlling the idling speed of an engine. Background technique [0002] If a car encounters a red light while the car is running, the car needs to stop and wait for the green light to come; Turn off and idle. Because the engine of the car may turn on or off a large electrical load when it is in the idling state, the opening or closing of the large electrical load will have an impact on the idling speed of the engine, causing the body of the car to vibrate or cause the engine to stall, affecting the interior of the car. Therefore, it is necessary to control the idle speed of the engine. [0003] At present, a method for controlling the idle speed of the engine is provided, specifically: ECU (Electronic Control Unit, electronic control unit) receives a request to turn on the electrical load, and immediately controls the electrical load to w...
