摘要： An arrangement for adjusting the torque of an internal combustion engine which drives a change-speed gear box and automatic gear changing device in dependence on stored characteristics with specified variation of required torque value as a function of power demand in which at least two different gears are each associated with an individual stored characteristic. Switch-in signals, derived from the gear changing device and which initiate switching of a stored characteristic into an adjustment element which influences the torque, contain information on a gear to be selected. Engine power is at least approximately constant for each engine operating point in engine characteristic field when changing between two associated stored characteristics for the required torque value. An adjustment element is controlled by the switch-in stored characteristic until the gear changing device switches to the gear having a different associated stored characteristic.

摘要： A device is provided for reducing the engine torque when shifting up a change-speed gear transmission connected downstream of an internal combustion engine. A final control element for influencing the engine torque is connected to a control circuit and causes a reduction in the engine torque only in the full load range of the internal combustion engine and only above a limit value of the negative changes in engine speed over time. Comparator circuits for positive changes in speed over time are connected to the final control element such that the reduction in engine torque is blocked above a limit value of the positive changes in speed over time. In this way, overshoots triggered by positive changes in speed over time cannot result in a reduction in the engine torque.
