    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: An electrically powered vehicle including an electric motor connected to drive a wheel of the vehicle. The electric motor receives a supply of electric current from a power source; a power electronics device and superordinated controller regulate the current supply based upon signals received from a driver or operator of the vehicle. A sensor for sensing data indicative of an accident or impending accident is connected to the superordinated controller in which the sensed data is compared to predetermined limit values to determine if an accident situation exists. Upon determining that an accident situation exists, the superordinated controller activates a circuit breaker to disconnect the electric power supply and thereby interrupt the supply of electric current to the electric motor.
