Field of the Invention The present invention relates to a method and apparatus for detecting an oil temperature of an automobile, and in particular, to construct an oil control apparatus for an automobile including a microcomputer (1), a transistor (Tr), and a solenoid (2), the coil of the solenoid (2). A resistor Ri provided between the ground and the ground to detect a current flowing through the solenoid; By adding an A / D converter 3 which converts the analog voltage induced in the resistor into a digital signal and inputs it to the microcomputer 1, the temperature of the oil can be detected by using the internal resistance value change of the solenoid coil. By reducing the elements required for temperature control of parts, the production cost of the product can be greatly reduced.
