What is the function of an automotive temperature sensor?
1 Answers
Automotive temperature sensors serve the following purposes: 1. They detect the ambient temperature outside the vehicle, and the control system determines the control method based on the difference between the outdoor temperature and the indoor temperature; 2. They provide the ECU with the temperature signal outside the vehicle cabin. The ECU compares this signal with the indoor temperature signal to determine the temperature inside the cabin, meeting the needs of the occupants. For example: if the outdoor temperature is 5 degrees and the indoor temperature is 30 degrees, the temperature difference is too large. The ECU will control the air conditioning to operate, reducing the indoor temperature to around 20 degrees. At this point, people inside the vehicle will not feel too hot or too cold. The automotive temperature sensor is installed on the front bumper mounting bracket and is a thermistor.
