Description

Technical Field

[0001] This utility model belongs to the field of automated testing technology, specifically relating to an automated testing device for vehicle-mounted temperature sensors. Background Technology

[0002] Onboard temperature sensors play several important roles in automobiles. First, they detect the ambient temperature outside the vehicle and, through the control system, adjust the interior temperature based on the temperature difference between the outside and inside, providing a more comfortable environment for passengers. Simultaneously, the onboard temperature sensor provides the outside temperature signal to the ECU (Electronic Control Unit). The ECU compares this signal with the interior temperature to determine a suitable temperature, ensuring that passengers do not feel overheated or overcooled. Onboard temperature sensors come in different types depending on their location within the vehicle, including coolant temperature sensors, transmission oil temperature sensors, and intake air temperature sensors. Regardless of the type, after assembly, temperature sensors require end-of-life (EOL) testing, weighing, and other tests to determine if the assembled product meets quality standards. Products that pass or fail are then categorized. Currently, most of this process is done manually, resulting in low overall efficiency. Utility Model Content
