What does COM mean in a car?
2 Answers
COM in a car refers to the serial communication port. Here are the meanings of other buttons in a car: 1. SRC: SRC stands for Synchronous Remote Control, which is the source selection key used to switch between CD/USB/radio/Bluetooth audio, or to switch between songs and radio stations. It functions like a remote control and is usually located on the multifunction steering wheel. 2. Auto: In car button labels, Auto represents the automatic function. Generally, there are two positions labeled with Auto in a car: one is the automatic air conditioning button, and the other is the Auto position on the automatic headlight knob. The Auto button for automatic air conditioning is located on the central dashboard, on the air conditioning control panel. Pressing this button will activate the automatic air conditioning.
Regarding the 'com' on a car, usually found on the air conditioning panel, 'com' stands for comfort mode. It is an intelligent function of the air conditioning system. After pressing this button, the system automatically adjusts the temperature, fan speed, and airflow direction inside the car without requiring manual intervention. This design is based on data collected by sensors inside and outside the vehicle, such as external sunlight intensity or temperature changes. It calculates and optimizes parameters in real-time to ensure the cabin maintains the most comfortable constant temperature. For example, on a scorching summer day, pressing 'com' will cause the air conditioning to rapidly cool the cabin before adjusting to a suitable airflow, avoiding direct blasts that might cause discomfort. This feature is installed in most modern cars, enhancing driving convenience and allowing more focus on road conditions. If a car does not have automatic air conditioning, the 'com' mode will not function, so it's important to check the vehicle's configuration before purchasing or using it.
