Abstract: The shift sequence for a transmission ratio change of a vehicle drive train is determined depending on an operating state of the vehicle drive train existing upon the actual transmission ratio of the transmission device. The operating state is characterized by various operating state quantities of the vehicle drive train, which represent input quantities of a model representing the vehicle drive train. Output quantities of the model supply at least one target value that determines the shift sequence in terms of characterization and application as input quantities of an optimization routine, by which a minimization of the functional connection of at least one target value is carried out. The torque characteristics representing the shift sequence of devices of the vehicle drive train are determined depending on the minimum of the functional connection of at least one target value, taking into account the limits of the operating state quantities.

Abstract: A method for determining a shift sequence of a change of transmission ratio of a transmission device of a vehicle drive train is described. The shift sequence is determined depending on an operating state of the vehicle drive train existing upon the actual transmission ratio inserted in the transmission device. The operating state is characterized by various operating state quantities of the vehicle drive train, which represent input quantities of a model representing the vehicle drive train (B2).

Abstract: An automated motorcycle transmission comprises a shift actuator (1) for engaging the gears of the transmission. The shift actuator (1) is a three-position actuator with self-maintaining end position stability which has first and second stable end positions and a stable central position. The shift actuator (1), when in the first end position, corresponds to a first gear of the transmission, the shift actuator (1), when in the second end position, corresponds to other gears of the transmission, and the shift actuator (1), when in the central position, corresponds to a neutral position of the transmission.

Abstract: An actuator is provided for a two-part stabilizer, which builds up a spring rate in its opened position. A hydraulic absorbing unit (9) is arranged on the axle of the switchable coupling unit (8). The absorbing unit is connected to one stabilizer part (4), on the one hand, and to the other stabilizer part (5), on the other hand. The absorbing unit forms at least one pressure chamber (32) and a suction chamber (33) and assumes a blocked position in the locked position of the switchable coupling (8) and counteracts the relative twisting motion between the two stabilizer parts (4, 5) at a hydraulic spring rate in the opened position of the switchable coupling (8).

Abstract: Vehicle with a vehicle body (7); at least two wheels (3, 4), which are connected to the vehicle body (7) and are movable in relation thereto; a stabilizer (10), which has two legs (11, 12) connected mechanically to one another via a torsion spring (13); two actuators (16, 17), via which the legs (11, 12) are coupled with the wheels (3, 4); and a control means (21), by means of which the coupling characteristic of the actuators (16, 17) can be varied, wherein an additional spring (8, 9) each is led around each of the actuators (16, 17) on the outside, and wherein the legs (11, 12) are additionally connected to the wheels (3, 4) via the additional springs (8, 9).

Abstract: A switchable stabilizer is provided as a compact assembly unit. The hydraulic system of the hydraulic and control part (9) may form a closed circuit with the piston-and-cylinder unit of the switchable coupling unit (3)and the hydraulic and control part (9) may be integrated in the cylindrical housing (10) of the switchable coupling (3).
