The active air intake grille is an air intake grille that can adjust its opening and closing. The active air intake grille can adjust the opening or closing state of the air intake grille according to vehicle speed and coolant temperature. After the vehicle is started, the active air intake grille can adjust the opening and closing degree according to the temperature of the coolant, thereby achieving the effect of quickly warming up the car and putting the vehicle into working condition in a short time. During high-speed driving, keeping the air intake grille open will increase wind resistance. If the air intake grille is closed in a timely manner, it will bring a lower wind resistance coefficient to the vehicle, thus improving vehicle stability.主动进气格栅就是可以调节开合度的进气格栅。主动进气格栅可以根据车速、冷却液温度调节进气格栅的打开或关闭状态，在车辆启动后，主动进气格栅可以根据冷却液的温度调节开合度，从而达到快速热车的效果，使车辆在较短时间内进入工作状态。在高速行驶中，进气格栅一直处于开启状态会增大风阻，如果进气格栅适时关闭，就会为车辆带来更低的风阻系数，从而提升车辆稳定性。
Principle explanation原理说明
|
1. |
There is one active grille (AGS) actuator, which is arranged on the lower grille;主动格栅（AGS）执行器有一个，布置在下格栅； |
|
2. |
When the active grille is powered on normally and loses LIN communication, the normal working condition is: fully open.主动格栅在正常通电情况下，丢失LIN通信后，常规工况：全开。 |
|
3. |
Under normal working conditions, the active grille will be powered off immediately and the grille blades will remain in the current state; if the grille blades are opened at a small opening at this time, it may cause the motor to overheat and report an error.主动格栅在正常工作情况下，立即掉电，栅叶会保持在当前状态；此时若栅叶开度较小，有可能会引起电机过热而报错。 |
|
4. |
AGS fuse advice is independent. It is really necessary to recommend sharing fuse with nodes with a higher security level that are not likely to affect each other.AGS保险建议独立。实在需要共用建议与安全等级较高的、不容易互相影响的节点共用保险。 |
