Shift-by-wire switch test device, system and method

Abstract

The invention discloses a shift-by-wire switch test device, system and method based on a six-degree-of-freedom mechanical arm. The test device comprises a position information management system for establishing a space coordinate system for determining all working planes of the mechanical arm in a working area of the mechanical arm, a test module for sending a test instruction corresponding to a test case according to the test case selected by a user, a motion control module and a shooting module. The test module is also used for obtaining the gear, where a shift-by-wire switch locates, according to a position map, judging whether the gear obtained when the mechanical arm reaches a preset target position corresponding to the test instruction is consistent with the gear, where the shift-by-wire switch locates, and testing whether the shift-by-wire switch is qualified. The shift-by-wire switch test device, system and method comprise the six-degree-of-freedom mechanical arm and the test system corresponding to the six-degree-of-freedom mechanical arm; motion redundancy thereof can meet test requirements of a new shift-by-wire switch; and the shift-by-wire switch test device, system and method have stable repeatability and wide application range.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a testing device, system and method for a shift-by-wire switch. Background technique [0002] With the development of shift-by-wire switch technology, its design form, function, motion mode and complexity have greatly changed and improved, which also poses new challenges to the automated test system. At present, for the traditional shifting system, the servo system is generally used for single-axis or multi-axis operation test or calibration. Its advantage is that the technology is mature and reliable; but its disadvantages are also obvious. , With 3D Hall positioning as the core technology, the shift-by-wire switch that can move in space, the movement margin of the traditional test system cannot meet the test requirements under the new design conditions. [0003] Therefore, how to provide a test device, system and method for a shift-by-wire switch that solves the above technica...
