  • Patent number: 7334496
    Abstract: A shifting device is provided for controlling the gear selection of a motor vehicle transmission with a housing, with a gearshift lever, which is arranged within a recess of the housing and can be pivoted in at least one vertical plane. A cover plate follows the pivoting movement of the gearshift lever due to its coupling with the gearshift lever. A scanning device includes sensors and corresponding signal transmitters for detecting the individual gear positions of the transmission. The scanning device has a sensor (10) arranged stationarily at the housing and a linear signal transmitter unit (13) at the pivotable cover plate (14), which said signal transmitter unit (13) sweeps over the scanning range of the sensor (9) and is provided with mark points for the gear positions, wherein the signals picked up by the sensor for the gear position are sent to a corresponding processor unit (12) for evaluation and forwarding. The shifting device for motor vehicle transmissions is inexpensive and reliable in operation.

  • Patent number: 7334497
    Abstract: A shifting device for the preferably powerless transmission of shift commands to a fully automatic or semi-automatic transmission of a motor vehicle and a frame and/or housing and a gearshift lever mounted pivotably along a shift gate. A first shift stop and a second shift stop are provided for the gearshift lever which each define a shift position for the said gearshift lever. At least one detection device is provided for detecting the shift position(s). An inoperative position is provided into which the gearshift lever pivots back by itself from the deflected shift position, driven by a restoring force. The shifting device has an actuating device, which can countermand a shift stop, so that the gearshift lever can be pivoted beyond the shift position(s) defined by this shift stop.

  • Patent number: 7322457
    Abstract: A shifting device (1) for the mechanical coupling-free transmission of shift commands to an automatic transmission of a motor vehicle (shift-by-wire shifting), with at least one housing and/or one frame and one selector lever for the manual selection of shift commands for the vehicle transmission in at least one shift gate. The selector lever can be moved manually into at least four positions (P, R, N, D), pivotable about at least one shift axis. A transmission device(s) transmits the shift commands without mechanical coupling with the vehicle transmission (shift by wire). A mechanical coupling (16) is provided between the selector lever (2) and the transmission of the vehicle. This mechanical coupling (16) activates the parking brake exclusively and automatically when the selector lever (2) is engaged in the P position and is automatically uncoupled from the selector lever when the selector lever (2) is pivoted out beyond the adjacent position.
