  • DETAILED DESCRIPTION
  • Embodiments of the present disclosure are described herein. It is to be understood, however, that the disclosed embodiments are merely examples and other embodiments can take various and alternative forms. The figures are not necessarily to scale; some features could be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present transmission shifter. As those of ordinary skill in the art will understand, various features illustrated and described with reference to any one of the figures can be combined with features illustrated in one or more other figures to produce embodiments that are not explicitly illustrated or described. The combinations of features illustrated provide representative embodiments for typical applications. Various combinations and modifications of the features consistent with the teachings of this disclosure, however, could be desired for particular applications or implementations.
  • An example front-wheel-drive vehicle 20 is schematically illustrated in FIG. 1. It is to be understood, however, that the vehicle could be rear-wheel drive, four-wheel drive, or all-wheel drive. The vehicle 20 includes an engine 22 coupled to a transmission 24. The transmission 24 transmits power from the engine 22 to a differential at a shaft speed suited to current vehicle needs, which may be faster or slower than the shaft speed at which engine 22 generates power. The differential reduces the shaft speed by a fixed final-drive ratio and transmits the power to the left and right driven wheels 28 via front half shafts 26.
  • The vehicle 20 includes a controller 36. The controller 36 may be a vehicle-based computing system that includes one or more controllers that communicate via a serial bus, e.g., Controller Area Network (CAN), or via dedicated electrical conduits. The controller 36 generally includes any number of microprocessors, ASICs, ICs, memory, e.g., FLASH, ROM, RAM, EPROM and/or EEPROM, and software code to co-act with one another to perform a series of operations. The controller 36 also includes predetermined data, or “look up tables” that are based on calculations and test data, and are stored within the memory. The controller 36 may communicate with other vehicle systems and controllers over one or more wired or wireless vehicle connections using common bus protocols (e.g., CAN and LIN). Used herein, any reference to “a controller” refers to one or more controllers.
  • The transmission 24 includes a manually-operated transmission shifter 30 (also known as a gear selector) that includes a plurality of transmission mode defining positions including at least PARK, REVERSE, NEUTRAL, and DRIVE positions. The transmission shifter 30 is linked to the transmission 24, either electrically or mechanically, to place the transmission 24 in the mode selected by the driver.
  • Referring to FIG. 2, the vehicle 20 includes a passenger cabin having a center console 40 disposed between the front seats of the vehicle. The center console 40 defines a shifter receiver 42 and a cup holder 44 adjacent to the shifter receiver 42. The transmission shifter 30 is connected to the center console 40 and includes at least a portion disposed within the shifter receiver 42. The transmission shifter 30 comprises a shifter body including a base 46 pivotally attached to the center console 40, a shaft 48 extending from the base, and a handle 50. Thus, the base 46 is provided at a first end of the shaft and the handle 50 is provided at a second end of the shaft.
  • The shifter base 46 may be pivotally attached to the center console 40 by a pivot such as a pin connection, a hinge, or other means known in the art. For example, the shifter receiver 42 may include opposing sidewalls 52 that define an aperture for receiving a pin that extends through the base 46. The transmission shifter 30 is pivoted about the connection between a plurality of angular positions, each corresponding to one of: PARK, NEUTRAL, REVERSE, DRIVE, and potentially others, e.g., LOW. To change the mode of the transmission 24, a driver pivots the transmission shifter 30 about the pivot point to place the transmission shifter 30 in the angular position of the desired mode. One or more detents may be provided in the shifter base 46 and/or the sidewalls 52 to secure the transmission shifter 30 in one of the plurality of positions and provide feedback to the driver.
  • More specifically, as illustrated in FIGS. 2 and 3, the PARK position of the transmission shifter 30 is at a forward-most angle. As illustrated in FIG. 6, the DRIVE position is a rear-most angle, and the NEUTRAL and REVERSE positions (see FIGS. 4 and 5 respectively) are therebetween. For example, the shaft 48 may form a 60° angle with a top 54 of the center console 40 when in PARK, may form a 75° angle when in REVERSE, may form a 90° angle when in NEUTRAL, and may form a 105° angle when in DRIVE and a fold-flat, 0° angle when in the storage position that is illustrated in FIG. 7 and described in greater detail below. These angular positions are but one example, and many other angular positions may be used for the various transmission modes.
  • Referring back to FIG. 1, the transmission shifter 30 may be electronically connected to the transmission 24 by a wired or wireless connection. For example, a sensor 60 may be disposed in the base 46 of the shifter 30 or in the center console 40. The sensor 60 is configured to sense an angular position of the shifter 30 and output a signal indicative of the angular position of the shifter to the controller 36. In some embodiments, the sensor 60 may be configured to determine which mode the shifter 30 is in, e.g., PARK, and output a signal to the controller 36 indicative of the currently selected mode. The controller 36 processes the signal from the sensor 60 and outputs a signal to the transmission 24 that commands the transmission to the driver-selected mode.
  • Referring to FIG. 7, console-mounted shifters are ergonomic for the driver, but take up console space and may limit possible console features that would be possible but for the shifter being in the way. The transmission shifter 30 includes a storage position SP in which the shifter is folded flat into the shifter receiver 42 placing the shifter 30 out of the way. In some embodiments, the shifter 30 nests within the shifter receiver 42, which is recessed into the console, so that the entire shifter 30 is below the top 54 of the center console 40 when in the storage position SP. The transmission shifter 30 may be displaced to the storage position SP when the vehicle is in PARK and remains in PARK when so displaced. The shifter 30 may be pivoted to the storage position SP by rotating the shaft 48 past the PARK position. The shifter 30 may include a lock 62 (see FIG. 1) that prevents the transmission shifter 30 from being pivoted to the storage position inadvertently. A release 64 (see FIG. 3), such as a button, may be located on the console 40 adjacent the transmission shifter 30 and operable to unlock the shifter allowing the shifter 30 to be rotated to the storage position SP.
  • In yet another embodiment, a cover is deployable over the shifter receiver 42 when the shifter 30 is in the storage position. The cover includes a top surface that is substantially flush with the top of the center console, i.e., within 0.5 millimeters of each other, to create a work surface suitable for writing or other tasks. A second cover may be deployable over the cup holders to increase the size of the work surface.
  • FIG. 8 illustrates another possible embodiment of the transmission shifter 30 wherein the plurality of mode defining positions selected when the transmission shifter projects from the shifter receiver 42 in the console 40 include the REVERSE position, the NEUTRAL position and the DRIVE position. In this embodiment the PARK position/transmission mode corresponds to the storage position SP wherein the transmission shifter 30 is fully received within the shifter receiver, recessed below the upper or top surface 54 of the console 40.
  • While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms encompassed by the claims. The words used in the specification are words of description rather than limitation, and it is understood that various changes can be made without departing from the spirit and scope of the disclosure. As previously described, the features of various embodiments can be combined to form further embodiments of the transmission shifter that may not be explicitly described or illustrated. While various embodiments could have been described as providing advantages or being preferred over other embodiments or prior art implementations with respect to one or more desired characteristics, those of ordinary skill in the art recognize that one or more features or characteristics can be compromised to achieve desired overall system attributes, which depend on the specific application and implementation. As such, embodiments described as less desirable than other embodiments or prior art implementations with respect to one or more characteristics are not outside the scope of the disclosure and can be desirable for particular applications.
