  • Method of control of an automatic transmission and a prognostic circuit for execution of this method
    Patent number: 4312249
    Abstract: In order to prevent a cyclic repeating of switching of vehicle gears to higher speeds for automatic transmissions at increased running resistances, an electronic control system is provided with a prognostic circuit which predicts the acceleration which can be expected after switching to a higher speed and which allows the switching to higher speeds only if this acceleration is above zero. If an adjusted maximum speed is exceeded, this operation of the prognostic circuit is interrupted.

  • Circuit arrangement for the regulation of the transmission stages on an automatic gear changer
    Patent number: 4194418
    Abstract: There is disclosed an electronic circuit arrangement for the regulation of the transmission stages of an automatic gear changer employed, for example, in a vehicle. The circuit includes a monostable circuit comprising an input transistor and an output transistor, the circuit being released by a pick-up device which is responsive to the speed of the vehicle. The circuit is substantially independent of variations of ambient temperatures and is of simple design.
