Abstract

The invention discloses a gear testing system and testing method, and relates to the technical field of gear testing. The system comprises a monostable electronic gear shifter used for outputting a first output signal, a brake analog switch used for outputting a second output signal, and a processor respectively connected with the monostable electronic shifter and the brake analog switch and usedfor calculating gear information according to the first output signal output by the monostable electronic gear shifter and the second output signal output by the brake analog switch and feeding back the gear information to the monostable electronic gear shifter, and the monostable electronic gear shifter is used for lightening a corresponding gear lamp according to the gear information. By arranging the monostable electronic shifter, the brake simulation switch and the processor, a simulation test environment based on a real vehicle is constructed, the monostable electronic shifter is comprehensively and systematically tested, the test strength of a product is greatly improved, and the quality of the product is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of gear testing, in particular to a gear testing system and testing method. Background technique

[0002] In the functional test of the current monostable electronic shifter, because the monostable electronic shifter manufacturer lacks the automatic transmission control unit (Transmissin Cntrl Unit, TCU) or vehicle control unit (Vehicle Cntrl Unit, VCU) to cooperate, so it can only simply test whether the change of the position of the shift handle can be output normally, to confirm whether the function of the monostable electronic shifter is normal. Such a test can only test the output function of the monostable electronic shifter, and cannot truly simulate the real gear information in the real vehicle environment to conduct a comprehensive test of the monostable electronic shifter function. Contents of the invention

[0003] The present invention aims to solve at least one of the technical problems exist...
