Problems solved by technology

[0005] However, if only four Hall ICs are replaced with 3D Hall ICs, after the assembly of the shift lever position detection device, that is, after the assembly of the shift lever unit, there will be deviations in assembly accuracy, and differences between the Hall ICs and the magnets will occur. The magnetic deviation of the magnet in the Hall IC caused by tolerances, etc.
Therefore, it is considered that the 3D Hall IC no longer correctly generates the electrical shift position signal, and it is difficult to detect the position of the shift lever with high precision.

Abstract

PROBLEM TO BE SOLVED: To detect the position of a change lever with excellent accuracy with a simpler structure. SOLUTION: The electric shift position signal value and the electric select position signal value of a Hall element 3 which are output corresponding to the magnetism of a magnet 2 in three ranges in the shift direction of the change lever and three ranges in the select direction of the change lever are recorded in a memory of the Hall element as the sensor characteristic values. Between ranges, the Hall element 3 performs the complementary output of the electric shift position signal value and the electric select position signal value corresponding to the position of the Hall element 3 as the sensor characteristic values by using the shift side virtual line connecting the adjacent electric shift position signal values to each other and the select side virtual line connecting the adjacent electric select position signal values to each other. Thus, even when various kinds of dispersions occur, the position of the change lever can be detected with excellent accuracy. COPYRIGHT: (C)2012,JPO&INPIT

Description

technical field [0001] The present invention relates to a shift lever position detection device for detecting the position of a shift lever operated for shift control of a vehicle transmission, a shift lever unit including the shift lever position detection device, and a shift lever position detection device The technical field of the method. Background technique [0002] In the transmission of the vehicle, the gear position of the transmission is set by operating the shift lever of the gear lever unit in the select direction and the shift direction orthogonal to the selection direction, and the gear position of the transmission is set. The transmission is controlled within the specified gear. Therefore, a shift lever position detection device that detects the position of the shift lever when a gear position is set is provided in the shift lever unit. [0003] As a conventional position detection device for a shift lever, in the position detection device for a shift lever ...
