Abstract

The invention discloses a gear recognition system and method. The gear recognition system includes a shift lever, an identification component relatively fixedly connected to the shift lever, and a reference member as a frame of reference. The shift lever and The identification assembly rotates or translates relative to the reference member, the reference member includes a reflective panel; the identification assembly includes a light emitting element, a light guide element, an optical sensor and an image analysis chip, and the light emitting element and the optical sensor are fixed It is arranged on the same side of the light guide element, the reflective panel is located on the other side of the light guide element, and the optical sensor is signally connected to the image analysis chip. The invention utilizes the optical principle to identify the rotation angle of the shift lever through the photoelectric device without being disturbed by the magnetic field, and has high identification and positioning accuracy and is not affected by assembly errors.

Description

technical field [0001] The invention relates to the technical field of shift-by-wire, in particular to a gear recognition system and method. Background technique [0002] With the development of passenger car technology, customers have higher and higher requirements for the automation and technology of passenger cars, and high-tech configurations are becoming more and more popular. The new model is equipped with a technological sense of wire control shift. Compared with mechanical shifting, shift-by-wire can significantly reduce the noise during the shifting process and improve the shifting quality of the vehicle, so it is more and more recognized and sought after by consumers. [0003] The gear position recognition of the existing shift-by-wire is generally realized by Hall sensors or micro switches. A group or a Hall sensor and a magnet cooperate to identify changes in the magnetic field to determine the target gear of the shifter, thereby identifying the driver. shift i...
