Abstract
The device for shifting an automatic transmission for motor vehicles has a selector lever, which makes possible an automatic uplifting and downshifting of the transmission in a first position as well as an additional arrangement on the steering wheel for manual downshifting or upshifting; this additional arrangement 2 is integrated within the steering wheel rim 1.
Claims18
A device for shifting an automatic transmission for motor vehicles in combination with a steering wheel with a steering wheel rim, the device comprising:
- a selector lever, which makes possible an automatic upshifting and downshifting of the transmission as a function of the speed of the vehicle and the speed of rotation of the engine in a first position;
- and
- an additional selector arrangement on the steering wheel, said additional selector arrangement being responsive to an application of force in a downshift direction to provide a manual downshifting and being responsive to an application of force in an upshift direction to provide a manual upshifting, said additional arrangement being integrated within the steering wheel rim as a segment covering a portion of a circumferential area of said steering wheel rim.
A motor vehicle automatic transmission shifting arrangement, comprising:
- a steering wheel with an annular steering wheel rim having an annular rim longitudinal axis;
- a selector lever, which makes possible an automatic upshifting and downshifting of the transmission as a function of the speed of the vehicle and the speed of rotation of the engine in a first position;
- and
- an additional selector on the steering wheel, said additional selector being integrated within the steering wheel rim as a single region segment covering a portion of a circumferential area of said steering wheel rim, said single region segment being responsive to an application of force in a downshift direction to provide a manual downshifting and responsive to an application of force in an upshift direction to provide a manual upshifting, said downshift direction being substantially opposite to said upshift direction based on an application of a rotational force about a longitudinal extent of said single region segment.
A motor vehicle automatic transmission shifting arrangement, comprising:
- a steering wheel with an annular steering wheel rim having an annular rim longitudinal axis;
- and
- a manual selector on the steering wheel, said manual selector being integrated within the steering, wheel rim as a single region segment covering a portion of a circumferential area of said steering wheel rim, said single region segment being responsive to an application of force in a downshift direction to provide a manual downshifting and responsive to an application of force in an upshift direction to provide a manual upshifting, said downshift direction being substantially opposite to said upshift direction based on an application of a rotational force about a longitudinal extent of said single region segment.
