Patent DE-4128627-A1 (DE)
Inventor: ADLER UWE DIPL ING
IPC: B60K31/00
Filed: 1991-08-26
Abstract: The invention relates to a process for changing the speed of a vehicle with driving wheels and a stepless revolution speed/torque characteristic curve in the drive train, especially a vehicle driven by an electric motor, corresponding to a change in the position alpha (t) of an operating pedal made by the vehicle driver, whereby to every pedal position  alpha (t) is allocated a given predetermined desired driving power Pv( alpha ) = f1( alpha ) x Pmax (where Pmax = maximum driving power of the vehicle) and/or an effective drive torque Mv( alpha ) = f1 alpha  x Mmax (where Mmax = maximum drive torque of the vehicle). In order to provide a process and device for its implementation which permits the driver to take the current travelling speed to a desired other value in the most uncomplicated and reliable manner for him, it is proposed, that the predetermined value Pv(t) and/or Mv(t) be converted for an electronic drive control of the vehicle, that the set value Ps(t) or Ms(t) be changed in an adjustment period to the predetermined value Pv(t) or Mv(t). The set value Ps(t) or Ms(t) is additively formed from an initial amount proportional to the predetermined value Pv(t) or Mv(t) and a residual proportion changing in time.

Title: Determining relative extreme values of signal for detecting shaft position of DC motor - comparing signal with maximum-minimum and minimum-minimum difference values to detect signal subject to noise pulses
IPC: H02P6/18
Filed: 1992-05-25
