Target idle speed and parking idle speed

What you want to ask is the difference between target idle speed and parking idle speed? Different application scenarios have different control purposes.

1, and the target idle speed refers to the idle speed when the car is running; Parking idle speed refers to the idle speed when the car is stationary.

2. When the vehicle is running, the engine will keep at the target idle speed by controlling the throttle opening and fuel injection. However, when the engine is idling, there is no external load (such as drive, air conditioner, generator, etc. ), the engine speed will be lower than the idle speed when driving.
