As shown in fig. 17, the sliding electronic shifter of the present invention has three operating positions, namely a steady state position (O position), an F1 position, and an R1 position. When not in operation, the slider body 81 is in a steady-state position, the slider body 81 is operated to move forward to reach the F1 position, and the slider body 81 is operated to move backward to reach the R1 position. When a gear change is required, the operating mechanism 9 is operated once forward or backward to reach the F1 position or the R1 position, and a gear change request is sent once. For example, if the current gear is N gear, moving the slide block body 81 forward to the F1 position, changing to R gear, moving the slide block body 81 backward to the R1 position, cutting into D gear; if the current gear is D gear, moving the sliding block body 81 forward to F1 position, cutting into N gear, moving the sliding block body 81 backward to R1 position, the gear remains unchanged, if the gear is to be shifted from D gear to R gear, the sliding block body 81 needs to be moved to F1 position twice, or the sliding block body 81 is kept at F1 position for more than 2 seconds, and the specific control strategy can be specified according to the requirement, which is not repeated in the present invention.

During the movement of the slider body 81, when the slider body 81 is located at a steady-state position (O position) of the middle part of the shifter housing 80 or within a certain range around the steady-state position, the sliders of the first slider group 6 are in contact with the copper clad sheets of the first copper clad sheet group 15, and are connected with the I/O port of the MCU through the internal circuit of the shifter circuit board 1, so that the interval sliders of the first slider group 6 and the corresponding copper clad sheets (e.g., O-1 and O-3, O-2 and O-4) of the first copper clad sheet group 15 form a passage; when the slider body 81 slides forward and leaves the steady-state position area, the sliding pieces of the first sliding piece group 6 are no longer in contact with the copper-clad pieces of the first copper-clad piece group 15, and the passage is disconnected. The whole process is similar to the same normally closed switch, when the operating mechanism 9 is not operated, the sliding block body 81 is positioned at a steady-state position, and the switch is closed, otherwise, the switch is opened;

when the slider body 81 slides forward into the F1 position area (or slides backward into the R1 position area), the sliders of the second slider group 4 (or the third slider group 5) contact with the copper clad sheets of the second copper clad sheet group 13 (or the third copper clad sheet group 14), a passage is formed between the shifter circuit board 1 and the MCU, but the position of the slider forming the passage is different from that of the slider body 81 in the steady-state position. When the sliding block body 81 is in the F1 or R1 position area, the adjacent sliding sheets of the second sliding sheet set 4 (or the third sliding sheet set 5) and the corresponding copper-clad sheets of the second copper-clad sheet set 13 (or the third copper-clad sheet set 14) form a passage.
