Automobile electronic gear shifting device and gear shifting method

Abstract

The invention discloses an automobile electronic gear shifting device and a gear shifting method. The automobile electronic gear shifting device comprises a gear level panel, a gear shifting rod and a circuit plate. The gear panel is marked with different gear levels such as R, D, E, N and P, a permanent magnet is fixedly arranged at the lower end of the gear shifting rod, the original position of the permanent magnet corresponds to the starting point of the circuit plate, and the circuit plate is provided with Hall sensors, wherein the Hall sensors respectively correspond to the gear levels of R, D, E, N, P which are marked on the gear level panel and are arranged on the left side, the upper side, the lower side, the right side, and the lower right side of the starting point. A gear shifting control unit on the circuit plate collects output signals of the Hall sensors respectively corresponding to every gear level, judges the switch state of the gear levels, and outputs a gear shifting control signal after the output signals are handled to a control unit of a transmission, and the control unit of the transmission controls a clutch actuator to conduct the gear shifting according to the gear shifting control signal. A smaller and longitudinal space arrangement can be achieved, error gear shifting is avoided, operation is simplified, and vehicle running safety in the gear shifting process is guaranteed.

Description

technical field [0001] The invention relates to an automotive electronic shifter and a shifting method. Background technique [0002] Electronic shifters are more and more used in modern automobiles due to their advantages of simple operation, easy layout, convenient installation, and sensitive response. Among them, the gear arrangement and reasonable shifting method are important development contents of the electronic shifter, which must not only meet the functional requirements of the vehicle, but also enable a better match between the shifter and the transmission to achieve the overall Vehicle reliability and safety. [0003] At present, automotive electronic shifters mainly use inline shifters and serpentine shifters. The gear positions of the inline shifter are arranged on the same vertical straight line (that is, the Hall sensors corresponding to the gear positions are arranged on the same vertical straight line), and the shifting action can be completed by moving th...

AI Technical Summary

Problems solved by technology

The gear positions of the inline shifter are arranged on the same vertical straight line (that is, the Hall sensors corresponding to the gear positions are arranged on the same vertical straight line), and the shifting action can be completed by moving the shift lever in one direction, but If the shifting force is too large, it is easy to cause mistaken gear shifting. In order to avoid mistaken shifting, an unlock button is added to the handball of the inline shifter, but it is inconvenient to operate the unlock button, and the gears are arranged vertically. The space is relatively large; the gear positions of the serpentine shifter are not arranged on the same longitudinal straight line, and the shift lever needs to move in at least two directions to complete the shift action, although it can pass through two or more directions The gear shifting movement prevents mis-shifting gears, but its gears are usually arranged vertically, which also requires a large vertical layout space

The gear positions of the electronic shifter of a car generally include P gear, R gear, N gear and D gear. In addition to the above gear functions, new energy vehicles can also include economic gear E gear or energy recovery gear. If the two kinds of shifters are added with economic gear or energy recovery gear, it will take up more layout space
