Temperature sensor signal processing device for determining temperature of oil of automatic transmission in motorvehicle, has output interface with output terminal, which is connected with sensor terminal and outputs processed sensor signal

摘要

The device (200) has a sensor interface (210) with sensor terminals (210a, 210b), where a temperature sensor (190) i.e. negative temperature coefficient sensor, is connected between the sensor terminals. A resistor (R1) is connected between a reference voltage terminal (240) and one of the sensor terminals. Another resistor (R2) is connected between the other sensor terminal and a ground (GND). An output interface (250) includes an output terminal (250a), which is connected with one of the sensor terminals and outputs a processed sensor signal. An independent claim is also included for a method for determining a temperature of transmission oil of a vehicle transmission.
