ATPS(Automatic Transmission Position Sensor) is the position sensor of an automatic transmission which transforms the gear changes into the electrical signals and transmits them to TCU. This paper deals with an development of the sensor output signal analysis system for ATPS inspection using LabVIEW. The developed system is designed to carry easily, and it can be installed for inspection directly in a car fitted with an automatic transmission. The system can not only detect the output signals of the sensor but also inspect the sensor behavior under the running state of a car. For this, the system is designed to control the position and the speed of motor. Also, it has the database system for the systematic output data management and the convenient GUI for user.

In this paper, a system of durability test for ATPS(Automatic Transmission Position Switch), which is used for automatic transmission, has been developed. ATPS is the position sensor for an automatic transmission which transforms the gear changes into the electrical signals and transmits them to TCU(Transmission Control Unit). This system can detect the output signals of the sensor, and also it has been designed to control the position and velocity of a motor to realize the sensor's movement under the running state of a car. And a database system and a GUI system have been developed for the systematic output data management and the convenient interface for users. Also, the operation data and the inspection reference data of a motor can be easily changed in this system, and with some modification the system is also able to used for the durability test of the similar products.
