DETAILED DESCRIPTION

[0020] Reference is now made to FIGS. 1a, 1b, 2, 3 and 4 which illustrate the new and improved apparatus 10 adapted to provide both an elegant push button transmission and a sporty manual stick shift transmission experience in accordance with the desires of the motor vehicle operator. That apparatus 10 includes an electronic transmission selector 12, a foldable, electronic shift knob 14 and a mechanical shift action module 16.

[0021] In the illustrated embodiment, the electronic transmission selector 12 comprises a plurality of push buttons 18, 20, 22, 24, 26 connected to a push button transmission electric module 28. More particularly, in the illustrated embodiment, the plurality of push buttons include a PARK mode push button 18, a REVERSE mode push button 20, a NEUTRAL mode push button 22, a DRIVE mode push button 24 and a SPORT mode push button 26. Thus, an operator may depress any of the push buttons 18, 20, 22, 24, 26 to select the desired operating mode of the motor vehicle transmission. Thus, for example, the motor vehicle operator may place the transmission of the motor vehicle equipped with the apparatus 10 into park by depressing the PARK mode push button 18. When the PARK mode push button 18 is depressed, the connected push button transmission electronic module 28 sends an appropriate control signal to the transmission control module causing the transmission control module 54 to place the motor vehicle transmission into park.

[0022] Other operating modes of the transmission may be selected by pushing the other push buttons 20, 22, 24, 26. Thus, for example, DRIVE mode may be selected by depressing the DRIVE mode push button 24 while SPORT mode may be selected by depressing the SPORT mode push button 26.

[0023] As best illustrated in FIGS. 1a and 1b, the apparatus 10 may include a console trim panel 30. That console trim panel 30 may include a first receiver 32, configured to receive the electronic transmission selector 12, and a second receiver 34, configured to receive the foldable, electronic shift knob 14. In the illustrated embodiment, the first receiver 32 and second receiver 34 are provided at two discrete locations. Accordingly, the electronic transmission selector 12 may be provided at the first discrete location in the first receiver 32 while the foldable electronic shift knob 14 may be provided at the second discrete location at the second receiver 34. By providing the various push buttons 18, 20, 22, 24, 26 of the electronic transmission selector 12 at a conveniently accessed first discrete location remote from the foldable electronic shift knob 14 provided at an easily accessed second discrete location fully independent push button transmission controls and manual stick shift controls are provided for the convenience of the operator. This ensures that the operator does not inadvertently depress a push button when controlling the transmission of the motor vehicle with the foldable, electronic shift knob 14.

[0024] As illustrated in FIGS. 1a, 1b, 3 and 4, the foldable electronic shift knob 14 includes a shank 36, a ball joint 38 at a proximal end of the shank and a shift knob feature 40 at a distal end of the shank. The ball joint 38 provides the foldable electronic shift knob 14 with a full range of movement similar to a joy stick allowing for movement in a forward and backward direction of the shift knob feature 40 as illustrated in FIG. 3, a left to right direction as illustrated by the action arrows in FIG. 4 and anything in between.

[0025] In the illustrated embodiment, the foldable, electronic shift knob 14 is displaceable between a stowed position, illustrated in FIG. 1a and a deployed position illustrated in FIG. 1b. In the stowed position illustrated in FIG. 1a, the foldable, electronic shift knob 14 is folded flat so that the shift knob feature 40 nests within a pocket 42 of the second receiver 34 provided in the upper surface of the console trim panel 30. The apparatus 10 may be configured so that the foldable, electronic shift knob 14 is maintained in the stowed position whenever the transmission of the motor vehicle is being operated in the PARK mode, the REVERSE mode, the NEUTRAL mode and the DRIVE mode. When the foldable, electronic shift knob 14 is in the stowed position, a free, uninterrupted space is provided along the top of the console trim panel 30.

[0026] In contrast, when the transmission of the motor vehicle is operated in sport mode (such as by depressing the sport mode push button 26 twice), the foldable, electronic shift knob 14 is displaced into the deployed position illustrated in FIG. 1b. In this deployed position, the shift knob feature 40 projects upwardly from the console trim panel 30 where the motor vehicle operator may easily engage the shift knob feature with the hand and manipulate the foldable, electronic shift knob 14 in the manner necessary to manually shift the transmission of the motor vehicle between gears thereby effectively providing for a more sporty driving experience. As this is done, the mechanical shift action module 16 connected to the foldable, electronic shift knob 14 provides the feel of a mechanical transmission linkage. That mechanical shift action module 16 may comprise a linear magnetic actuatorHD rumblesphericalencoder module of a type known in the art. Such a module is disclosed in, for example, US Patent Publication 2018-0028911. Also see WO2013134388 and WO2001024158. Of course, other modules or devices capable of providing the feel of a mechanical shift action transmission may be utilized.

[0027] As illustrated in FIG. 5, the apparatus 10 may further include a human interface 46 configured to select operating parameters of the foldable, electronic shift knob 14 when in the deployed position. In the illustrated embodiment, that human interface comprises a touchscreen display of a type that may be provided in the center stack of the instrument panel of the motor vehicle forward of the console trim panel 30.

[0028] More particularly, the human interface 46 may provide the operator of the motor vehicle with a plurality of shift configuration options including various standard shift patterns of a type known in the art, a sequential shift pattern in the fore-and-aft direction as illustrated in FIG. 3, and a sequential shift pattern in the left-to-right lateral direction as illustrated in FIG. 4. Depending upon the selection made, the mechanical shift action module 16 may be configured to provide the feel of a gated manual transmission of various different configurations.

[0029] Toward this end, it should be appreciated that the apparatus 10 may incorporate a main control module 48 connected to the human interface 46 and adapted or configured to control the mechanical shift action module 16 and provide the desired mechanical linkage experience to the operator when shifting the foldable, electronic shift knob 14 between gears. Such a control module 48 may comprise a computing device such as a dedicated microprocessor or electronic control unit (ECU) operating in accordance with instructions from appropriate control software. Thus, the control module 48 may comprise one or more processors, one or more memories and one or more network interfaces all in communication with each other over one or more communication buses.

[0030] FIG. 6 illustrates one possible embodiment of control logic flow diagram 50 for the apparatus 10. That control logic flow diagram 50 is self-explanatory. When the transmission of the motor vehicle is in normal or eco operating mode by selecting PARK, REVERSE, NEUTRAL OR DRIVE via the push buttons 18, 20, 22, 24, the foldable, electronic shift knob 14 is maintained in the stowed position illustrated in FIG. 1a with the shift knob feature 40 nested within the pocket 42 of the second receiver 34 in the console trim panel 30.

[0031] When the sport mode push button 26 has been depressed once, the transmission is operated in sport mode with the foldable, electronic shift knob 14 maintained in the stowed position. In contrast, when the sport mode push button 26 is depressed twice, full sport mode is activated and the foldable, electronic shift knob 14 is displaced into the deployed position illustrated in FIG. 1b where it may be engaged by the motor vehicle operator and manipulated to shift the transmission of the motor vehicle.

[0032] When the sport mode push button 26 is depressed three or more times, the apparatus 10 returns to normal/eco operating mold and the foldable, electronic shift knob 14 is displaced back into the stowed position illustrated in FIG. 1a. Here it should be noted that an actuator 52 connected to the foldable, electronic shift knob 14 and controlled by the control module 48 may function to displace the foldable, electronic shift knob 14 between the stowed position and the deployed position. That actuator 52 does not interfere with the mechanical shift-action module 16 that mimics or replicates the feel of a manual transmission having a shift knob feature 40 mechanically linked to the gearbox of the transmission.

[0033] The foregoing has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the embodiments to the precise form disclosed. Obvious modifications and variations are possible in light of the above teachings. For example, the electronic transmission selector 12 of the illustrated embodiment is a push button selector. In alternative embodiments, the electronic transmission selector 12 may comprise a dial selector or other appropriate means of selecting the operating mode of the transmission of the motor vehicle. All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
