A method and system for detecting a knob shifter

Abstract

The invention discloses a detection method and system for a knob shifter, which relates to the field of vehicle shifters, and specifically includes the steps of: after acquiring an initial point position signal of an execution part, clamping the shifter knob by a clamping part of the execution part; According to the preset gear angle, the actuator is controlled to drive the shifter knob to rotate and read the Hall value at each gear, and at the same time obtain the torque curve during the rotation of the knob; according to the Hall value at each gear The knob is calibrated, and the displacement-torque curve is drawn according to the angular relationship between the torque curve and the shifter knob; the torque of the shifter knob is adjusted according to the displacement-torque curve and the preset torque standard; according to the calibration results and adjustment results Barcodes are generated and printed on the knob shifter labels. By adjusting or recording various data that do not meet the standard parameters, the invention ensures that the parameters of the knob shifter meet the technical requirements when leaving the factory, and greatly reduces the defective rate of the product.

Description

technical field [0001] The invention relates to the field of vehicle shifters, in particular to a detection method and system for a knob shifter. Background technique [0002] The gear shifter of the vehicle shoulders the important responsibility of shifting the gear position of the vehicle. Its quality, accuracy and durability greatly affect the final driving state of the vehicle. This is especially obvious on electronic shifters such as knob shifters, because they are electronic shifters, and because of the safety settings of the shifter control chip, it is difficult for non-professional maintenance personnel to adjust them after leaving the factory. parameters are modified. Therefore, the calibration state of this type of electronic shifter at the factory has determined its later use effect. If this type of shifter is not well calibrated and quality controlled at the factory, it will undoubtedly affect the user's driving The experience brings great negative feelings. T...
