    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: The drive arrangement for a motor vehicle includes an internal combustion engine (1) with at least one controlling element (29), an electric generator arrangement (3) driven by the internal combustion engine (1), at least one electric motor (11) which is powered by the generator arrangement (3) and drives the motor vehicle, and an electronic control unit (19) which, depending on the setting of an accelerator pedal (23), controls at least an actuating drive (27) and the electrical output generated by the generator arrangement (3) and/or the electrical output received by the electric motor (11). 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.

    摘要: A slip control loop (13) is proposed which compares the actual differential speed between input and output speed of a friction clutch (5) of a motor vehicle with a desired differential value and adjusts a positioning drive (7) of the clutch (5) according to the desired differential speed. To increase the accuracy of control, a desired position signal from a clutch characteristic curve memory (25) is additively superimposed in the sense of an influencing variable on the desired position signal s' calculated by a controller (19) of the slip control loop (13). The clutch characteristic curve memory (25) stores the desired position signal s" as a function of the clutch moment which can be transmitted in this position and is addressed according to the instantaneous engine moment determined, for example, via an engine characteristic map (27). During a load change of the engine (1), the clutch (5) is adjusted to the expected moment before a significant change in the actual differential speed occurs. The controller (19) has an integrating controller property so that the integral portion of the desired signal s' is zero when the dimensioning of the clutch characteristic curve stored in the clutch characteristic curve memory (25) is corrected. A correcting device (33) allows step-wise correction of the characteristic curve as a function of the value of the integral portion.

    摘要: A hybrid drive arrangement for a motor vehicle including an internal combustion engine (1), which is connected or can be connected in a wheel-driving manner, via a first torque transmission path (11, 13), to a driving wheel (15) of the motor vehicle. An electric machine (19), which is operable at least as a motor, is fed from an electrical energy source (7, 29) of the motor vehicle and is connected or can be connected in a wheel-driving manner, via a second torque transmission path (21, 23, 13), to the driving wheel (15). Arranged in the first and/or the second torque transmission path are coupling elements (11, 23) which, in a first operating state, permit the driving of the motor vehicle by the wheel-driving torque of the electric machine (19), operated as a motor, without mechanical torque support from the internal combustion engine (1), and which, in a second operating state, permit the driving of the motor vehicle by the internal combustion engine (1), without mechanical torque support from the electric machine (19). Depending on the driving speed of the motor vehicle, an electronic driving control system (31) activates the first operating state, at least in a first range of driving speeds including standstill of the vehicle, if the driving speed is less than a predetermined speed limit, and activates the second operating state, at least in a second range including the maximum speed of the vehicle, if the driving speed is greater.
