Abstract

The invention discloses a gear recognition system and method. The gear recognition system involves a shift lever, a recognition assembly relatively fixedly connected with the shift lever and a reference member used as a reference system, wherein the shift lever and the recognition assembly rotate or move horizontally relative to the reference member, and the reference member comprises a reflectionface plate; and the recognition assembly comprises a light-emitting element, a light guide element, an optical sensor and an image analysis chip, the light-emitting element and the optical sensor arefixedly arranged on the same side of the light guide element, the reflection face plate is located on the other side of the light guide element, and the optical sensor is in signal connection with the image analysis chip. According to the gear recognition system and method, by means of the optical principle, the rotating angle of the shift lever is recognized through photoelectric equipment, interference of a magnetic field is avoided, the recognition and positioning precision is high, and the influence of assembly errors is avoided.

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...
