    摘要: A process for changing the speed of a vehicle with driving wheels and with a continuously adjustable speed/torque characteristic in the drive train, in particular a vehicle with electric motor drive, corresponding to a change in the position .alpha.(t) of an accelerator pedal carried out by the driver of the vehicle, in which every position .alpha.(t) of the accelerator pedal is associated with a determined drive output P.sub.v (.alpha.)=f.sub.1 (.alpha.).times.P.sub.max (where P.sub.max =maximum drive output of the vehicle) and/or driving torque M.sub.v (.alpha.)=f.sub.1 (.alpha.).times.M.sub.max (where M.sub.max =maximum driving torque of the vehicle) which is desired in the sense of a predetermined value and acts on the vehicle. To provide a process and a device for implementing the process permitting the driver to change the actual speed of the vehicle to a different desired value in the most uncomplicated and reliable manner, the predetermined value P.sub.v (t) and/or M.sub.v (t) is converted for an electronic drive control of the vehicle, the reference value P.sub.s (t) or M.sub.s (t) is changed to the predetermined value P.sub.v (t) or M.sub.v (t) within an adjustment time period, wherein the reference value P.sub.s (t) or M.sub.s (t) is formed by addition from an initial proportion proportional to the predetermined value P.sub.v (t) or M.sub.v (t) and a residual proportion changing over time.

    摘要: A system for automatic actuation of the clutch of a motor vehicle wherein a pneumatic cylinder operates a normally engaged clutch to disengage the clutch when fluid pressure is applied to the pneumatic cylinder. A valve system operated through a control system vents the pneumatic cylinder to effect engagement of the clutch and applies fluid pressure from a fluid pressure source to disengage the clutch. The control system is responsive to the position of a clutch activating element interposed between the clutch and the pneumatic cylinder as well as to the speed of the motor of the motor vehicle. Additionally, sensors responsive to the operating condition of a manually shiftable transmission also operate to control the fluid pressure condition of the pneumatic cylinder to determine actuation of the clutch.

    摘要: A clutch-release device for actuating a friction clutch of a motor vehicle includes a clutch-release mechanism which slides axially along a release axis and is in working connection with a release element to transmit a clutch-actuating force. The clutch-release device also has a clutch lever which pivots around a center of rotation in a pivoting plane of the lever essentially including the release axis. The clutch lever defines a force application point to the release mechanism for the transmission of the clutch-actuating force. The clutch-release mechanism and the release lever are arranged with respect to each other such that, when a release movement is performed to actuate the clutch, the radial deflection of the force application point relative to the release axis is minimized over the entire range of the release movement.

The arrangement contains a device for detecting an actual value of the speed of the internal combustion engine (1) and component for detecting an actual value of the electrical output generated by the generator arrangement (3). The control unit (19) has a speed regulating device (33) that maintains the actual speed at a given reference speed and an output regulating component (37) which maintains the actual electrical output at a given reference output. A data storage (31) in which performance data for combinations of data for the reference output with data for the reference speed and/or data for the adjustment of at least the actuating drive (27) are stored. In the event of dragging or motoring operation of the generator arrangement (3) and internal combustion engine (1), the control unit (19) detects the torque curve depending on the current of the generator arrangement (3) depending on the instantaneous angular position of the crankshaft and diagnoses operating errors and/or the state of the engine depending on the torque curve.
