A control lever (10) is provided with a grip (12), which in a joint (14) having two degrees of freedom is supported in a housing (11) and can be switched from an initial position in various directions for activating shift elements (18, 19), whereby spring elements (41, 42) are provided for returning
A control lever (10) is provided with a grip (12), which in a joint (14) having two degrees of freedom is supported in a housing (11) and can be switched from an initial position in various directions for activating shift elements (18, 19), whereby spring elements (41, 42) are provided for returning the grip (12) to its initial position, and with a functional device for overcoming a pressure point during the activation and/or for retaining a desired shift position. In order to provide functional devices in greater numbers in a gearshift lever of this type without requiring substantially more installation space or substantially higher costs, provision is made that the functional device is constituted by an electrically controllable hydraulic arrangement (35), which connects to diametrically opposing shift elements (18, 19), which can be activated by the grip (12) in two opposing directions of motion.

What is claimed is: 1. A lever (10), having a grip (12) which is supported by a joint (14) in a housing (11) wherein the joint has two degrees of freedom and that allow the grip to be shifted from an initial position in various directions for activating shift elements (18, 19), wherein spring eleme
What is claimed is: 1. A lever (10), having a grip (12) which is supported by a joint (14) in a housing (11) wherein the joint has two degrees of freedom and that allow the grip to be shifted from an initial position in various directions for activating shift elements (18, 19), wherein spring elements (41, 42) are provided for returning the grip (12) to its initial position, comprising: a functional device for overcoming a pressure point during the activation and/or for retaining a desired shift position, wherein the functional device is constituted by an electrically controllable hydraulic arrangement (35); said hydraulic arrangement (35) connects to a pair of shift elements (18, 19) that lie diametrically opposite each other and that can be activated by the grip (12) in two opposite directions of motion. 2. The lever as recited in claim 1, wherein the hydraulic arrangement (35) has a hydraulic cylinder (33, 34) that is assigned to each shift element (18, 119), and the two hydraulic cylinders (33, 34) are connected to each other by a pipe line (36, 37, 51), in which a throttling and/or blocking device (55) is arranged. 3. The lever as recited in claim 2, wherein the end (44) of the shift element (18, 19) that is facing away from the grip (12) directly or indirectly forms a hydraulic piston. 4. The lever as recited in claim 2 or 3, wherein the hydraulic arrangement (35) is filled with hydraulic oil, and the throttling and/or blocking device is formed in the pipe line by a valve that is electromagnetically controllable. 5. The lever as recited in claim 2 or 3, wherein the hydraulic arrangement (35) is filled with a magneto rheological fluid, and the throttling and/or blocking device has an electromagnet (55) that at least partially surrounds the pipe line (36, 37, 51) at one location. 6. The lever as recited in claim 3, wherein the hydraulic piston has a disk (45) that is arranged within the hydraulic cylinder (33, 34), that, axially stressed by a pressure spring (41, 42) within the hydraulic cylinder (33, 34), is supported on an interior shoulder of the hydraulic cylinder, and that is acted upon by the axially movable shift element (18, 19). 7. The lever as recited in claim 3, wherein a sleeve (36, 37) is inserted in a fluid-tight manner into the end of the hydraulic cylinder (33, 34) that is facing away from the shift element (18, 19), the hydraulic piston (45) of the activated shift element (18, 19) contacting the interior end of the sleeve. 8. The lever as recited in claim 7, wherein the end (39) of a sleeve (36, 37) of the hydraulic arrangement (35) that protrudes from the hydraulic cylinder (33, 34) is at least partially surrounded by the electromagnet (55). 9. A control which includes a grip that can be moved at least in first and second opposite directions, a pair of shift elements that are spring biased toward opposite sides of said grip and that are each depressable when the grip is moved in a corresponding direction, comprising: walls forming a pair of fluid chambers containing fluid, with each shift element being moveable into a corresponding chamber to compress the fluid therein and urge it to flow out of the chamber; operable means for controllably resisting the flow of fluid that lies in one of said chambers, out of the chamber, to thereby provide controllable resistance to the depression of the corresponding shift element. 10. The control described in claim 9 wherein: said fluid in said fluid chambers is a magneto rheological fluid whose viscosity varies when it lies in a magnetic field that varies and said means for controllably resisting includes an electromagnet.
