Electromotive type range switching arrangement null of automatic

摘要

PURPOSE: To improve mountability by generating a voltage value correctable of a valve position sensor for generating an output signal in accordance with each range position, so as to eliminate necessity for adjusting reference potential at the time of installation in a vehicle, in an electrically-operated range shift device for actuating a drive motor by operating an electric switch. ;CONSTITUTION: In a detent mechanism controlling a manual valve through a reduction gear 3 and a manual shaft 5 by power of a motor 2 driven by operating a range select switch 41, changing a rotational position of the detent mechanism can be detected by a valve position sensor 23. A changing rate of an output value of the valve position sensor 23 is compared with a reference value, to judge a position of the manual shaft 5. A memory 33, storing one after another a voltage value in accordance with each range position detected by the sensor 23, is provided, and in a CPU31, the voltage value stored in the memory 33 is learned so as to correct this learning voltage value as a new range position corresponding voltage value.;COPYRIGHT: (C)1995,JPO
