Collision warning and avoidance system (CWAS): There are many forms of this system. Some of them will automatically alarm when the distance between the two vehicles is as small as the safe distance when the car is driving. , Automatically control the car brake to stop the car; some show the distance of obstacles behind the car when the car is reversing, effectively preventing the occurrence of reversing accidents.
Automobile air conditioning automatic temperature control (Automatic Temperature Control, ATC), commonly known as constant temperature air conditioning system. Once the target temperature is set, the ATC system will automatically control and adjust to keep the temperature inside the vehicle at the set value. The automatic air conditioning system consists of five parts: refrigeration system, heating system, ventilation (gas distribution) system, automatic control system, and air purification system.
The composition of the automatic temperature control system includes temperature sensors, control system ECU, actuators, etc. The temperature sensors include the outside air temperature sensor, the inside air temperature sensor, the sunlight sensor (sunlight intensity sensor) and the evaporator temperature sensor.
