摘要： A regulating device for an electromagnetic control element, especially for an internal combustion engine with auto-ignition, is proposed in which a non-linear regulator with preferably a PD characteristic is coupled with a pulse regulator, preferably a two-point regulator with PID characteristic. Of special advantage is the interposition of a limiting device, which allows an increase in the D portion of the non-linear regulator, while at the same time suppressing interference. This results in an excellent control behavoir, especially in the face of small control deviations and in a control element or control circuit afflicted with friction and/or (magnetic) hysteresis.

摘要： After the gear ratio of an automatic transmission has been increased in response to a braking operation the return to normal operation of the automatic transmission is controlled by logic circuits interconnecting threshold switches operated by the brake pedal and the accelerator pedal and by a read-only memory that stores a maximum engine speed for all values of vehicle speed so that the higher gear ratio is maintained until either the brake is released or the maximum engine speed is exceeded and then the return to normal transmission operation is further delayed until the accelerator pedal is again actuated. In one method, during the period of further delay the gear ratio continues at its raised value. In another embodiment the period of further delay begins with storage of the vehicle speed at the moment and proceeds with control of the transmission to maintain that speed. It is also possible to operate the system so as not to restore normal operation of the transmission after braking when there is only a slight depression of the accelerator pedal.
