Furthermore, a “P” display 18P, an “R” display 18R, an “N” display 18N, and a “D” display 18D are displayed in the center of the P position 20P, the R position 20R, the N position 20N, and the D position 20D, respectively.

[0027] A rectangular electrostatic sheet 22 as a detection member is fixed to the back side of the plate 18 , and the electrostatic sheet 22 covers the back side of the plate 18 .

[0028] On the front side of the electrostatic sheet 22, there are provided internal electrodes 24 serving as a detection portion (internal detection portion), namely, a rectangular thin film-shaped internal P electrode 24P, an internal R electrode 24R, an internal N electrode 24N and an internal D electrode 24D. The internal P electrode 24P, the internal R electrode 24R, the internal N electrode 24N and the internal D electrode 24D are set to have the same size and face the central portions of the P position 20P, the R position 20R, the N position 20N and the D position 20D in the front-to-back direction (the wall thickness direction of the plate 18), respectively.

[0029] On the front side of the electrostatic sheet 22, an external electrode 26 serving as a detection portion (external detection portion), namely, a rectangular frame thin film-shaped external P electrode 26P, an external R electrode 26R, an external N electrode 26N and an external D electrode 26D, is provided. The external P electrode 26P, the external R electrode 26R, the external N electrode 26N and the external D electrode 26D are set to the same size, and their outer peripheries in the front-to-back direction are respectively opposite to the outer peripheries of the P position 20P, the R position 20R, the N position 20N and the D position 20D.

[0030] The inner periphery of the outer electrode 26 (outer P electrode 26P, outer R electrode 26R, outer N electrode 26N, and outer D electrode 26D) is arranged along the outer periphery of the inner electrode 24 (inner P electrode 24P, inner R electrode 24R, inner N electrode 24N, and inner D electrode 24D), and a gap is provided between the inner electrode 24 and the outer electrode 26. The inner electrode 24 and the outer electrode 26 are made of metal, for example, and have conductivity.

[0031] The inner P electrode 24P, the inner R electrode 24R, the inner N electrode 24N, the inner D electrode 24D, and the outer P electrode 26P, the outer R electrode 26R, the outer N electrode 26N, and the outer D electrode 26D of the electrostatic sheet 22 are electrically connected to the vehicle control device 28, and the vehicle transmission 30 (automatic transmission) is electrically connected to the control device 28. The control device 28 is provided with a microcomputer that connects a CPU, a ROM, a RAM, a nonvolatile memory (storage), etc. through a bus. In the control device 28, the CPU reads out the program stored in the ROM and the storage, expands it in the RAM, and executes the program, thereby realizing various functions.

[0032] Next, the operation of this embodiment will be described.

[0033] In the shift device 10 with the above structure, when the passenger touches the P position 20P, R position 20R, N position 20N or D position 20D of the panel 16 (plate 18) with the finger F, the inner P electrode 24P of the panel 16 (electrostatic sheet 22) and the outer P electrode 26P of the panel 16 (electrostatic sheet 22) and the inner R electrode 24R of the panel 16 (electrostatic sheet 22) and the inner R electrode 24R of the panel 16 (electrostatic sheet 22) and the outer R electrode 26P of the panel 16 (electrostatic sheet 22) are respectively connected to the surface of the shift device 10. Electrostatic capacitance is generated between the inner and outer R electrodes 26R, between the finger F and the inner N electrode 24N in the panel 16 (electrostatic sheet 22) and between the finger F and the outer N electrode 26N in the panel 16 (electrostatic sheet 22), or between the finger F and the inner D electrode 24D in the panel 16 (electrostatic sheet 22) and between the finger F and the outer D electrode 26D in the panel 16 (electrostatic sheet 22) (contact of the finger F with the P position 20P, the R position 20R, the N position 20N or the D position 20D is detected).

[0034] When finger F contacts P position 20P, and the electrostatic capacitance (detection value) between finger F and inner P electrode 24P is above the inner capacitance threshold and the electrostatic capacitance between finger F and outer P electrode 26P is above the outer capacitance threshold for a period of time longer than a time threshold (for example, 0.5 seconds), the control device 28 determines that P position 20P is selected, and changes the gear of the transmission 30 to the corresponding P gear (parking gear) through the control of the control device 28.

[0035] When the finger F contacts the R position 20R, and the electrostatic capacitance between the finger F and the inner R electrode 24R is above the inner capacitance threshold and the electrostatic capacitance between the finger F and the outer R electrode 26R is above the outer capacitance threshold for a period of time longer than the time threshold, the control device 28 determines that the R position 20R is selected, and changes the gear of the transmission 30 to the corresponding R gear (reverse gear) through the control of the control device 28.

[0036] When the finger F contacts the N position 20N, and the electrostatic capacitance between the finger F and the inner N electrode 24N is above the inner capacitance threshold and the electrostatic capacitance between the finger F and the outer N electrode 26N is above the outer capacitance threshold for a period of time exceeding the time threshold, the control device 28 determines that the N position 20N is selected, and changes the gear of the transmission 30 to the corresponding N gear (neutral) through the control of the control device 28.

[0037] When the finger F contacts the D position 20D, and the electrostatic capacitance between the finger F and the inner D electrode 24D is above the inner capacitance threshold and the electrostatic capacitance between the finger F and the outer D electrode 26D is above the outer capacitance threshold for a period of time exceeding the time threshold, the control device 28 determines that the D position 20D is selected, and changes the gear of the transmission 30 to the corresponding D gear (forward gear) through the control of the control device 28.

[0038] In addition, when the passenger touches the middle of the P position 20P and the R position 20R, the middle of the R position 20R and the N position 20N, or the middle of the N position 20N and the D position 20D with his finger F, electrostatic capacitance is generated between the finger F and the external P electrode 26P and between the finger F and the external R electrode 26R, between the finger F and the external R electrode 26R and between the finger F and the external N electrode 26N, or between the finger F and the external N electrode 26N and between the finger F and the external D electrode 26D (contact of the finger F between the P position 20P and the R position 20R, between the R position 20R and the N position 20N, or between the N position 20N and the D position 20D is detected).

[0039] When the finger F contacts the middle of the P position 20P and the R position 20R, if the electrostatic capacitance between the finger F and the outer P electrode 26P is greater than the differential capacitance threshold relative to the electrostatic capacitance between the finger F and the outer R electrode 26R for a time period greater than the time threshold, the control device 28 determines that the P position 20P is selected, and changes the gear of the transmission 30 to the P gear position through the control of the control device 28. On the other hand, if the electrostatic capacitance between the finger F and the outer R electrode 26R is greater than the differential capacitance threshold relative to the electrostatic capacitance between the finger F and the outer P electrode 26P for a time period greater than the time threshold, the control device 28 determines that the R position 20R is selected, and changes the gear of the transmission 30 to the R gear position through the control of the control device 28.

[0040] When the finger F contacts the middle of the R position 20R and the N position 20N, if the state where the electrostatic capacitance between the finger F and the outer R electrode 26R is greater than the difference capacitance threshold with respect to the electrostatic capacitance between the finger F and the outer N electrode 26N continues for a time greater than the time threshold, the control device 28 determines that the R position 20R is selected, and changes the gear of the transmission 30 to the R gear position through the control of the control device 28. On the other hand, if the state where the electrostatic capacitance between the finger F and the outer N electrode 26N is greater than the difference capacitance threshold with respect to the electrostatic capacitance between the finger F and the outer R electrode 26R continues for a time greater than the time threshold, the control device 28 determines that the N position 20N is selected, and changes the gear of the transmission 30 to the N gear position through the control of the control device 28.

[0041] When the finger F contacts the middle of the N position 20N and the D position 20D, if the state where the electrostatic capacitance between the finger F and the outer N electrode 26N is greater than the difference capacitance threshold with respect to the electrostatic capacitance between the finger F and the outer D electrode 26D continues for a time greater than the time threshold, the control device 28 determines that the N position 20N is selected, and changes the gear of the transmission 30 to the N gear position through the control of the control device 28. On the other hand, if the state where the electrostatic capacitance between the finger F and the outer D electrode 26D is greater than the difference capacitance threshold with respect to the electrostatic capacitance between the finger F and the outer N electrode 26N continues for a time greater than the time threshold, the control device 28 determines that the D position 20D is selected, and changes the gear of the transmission 30 to the D gear position through the control of the control device 28.

[0042] Here, the outer electrode 26 of each shift position 20 detects the contact of the finger F between the shift positions 20 and determines the selection of the shift position 20. Therefore, it is not necessary to provide additional electrodes (detection units) between the shift positions 20.

[0043] Furthermore, when the finger F touches the middle of the first shift position 20 and the second shift position 20 and the detection value of the electrostatic capacitance of the outer electrode 26 of the first shift position 20 relative to the outer electrode 26 of the second shift position 20 is equal to or greater than the difference capacitance threshold, the first shift position 20 is selected. Therefore, even if the finger F touches the middle of the shift position 20, the shift position 20 can be selected.

[0044] When the finger F touches a shift position 20, the shift position 20 is selected if the electrostatic capacitances of the inner electrode 24 and the outer electrode 26 of the shift position 20 are equal to or greater than the inner capacitance threshold and the outer capacitance threshold, respectively. Therefore, each shift position 20 can be selected.

[0045] In addition, the inner electrode 24 is arranged on the central side of the shift position 20, and the outer electrode 26 is arranged on the outer peripheral side of the shift position 20. Therefore, it is possible to detect the contact of the finger F to the central side of the shift position 20 and the contact of the finger F to the outer peripheral side of the shift position 20, and it is possible to detect the contact of the finger F to the shift position 20 and the contact of the finger F to the middle of the shift position 20.

[0046] In addition, the outer electrode 26 is arranged at the portion of the shift position 20 near the other shift position 20. Therefore, it is possible to detect the contact of the finger F with the portion of the shift position 20 near the other shift position 20, and it is possible to detect the contact of the finger F with the middle between the shift positions 20.
