ABSTRACT:
An arrangement controls a drive engine when changing up a variable-speed transmission downstream in the power flow in order to reduce the engine torque. Given a lack of a torque reduction due to a malfunction, emergency operation is initiated in the system by accomplishing the change up rapidly through an increase in the operating pressure in the variable-speed transmission. To this end, an emergency switching stage, which operates as a function of the operating point of the drive engine, can be moved into a position to transmit a pressure control signal for the gear changing device of the variable-speed transmission when the gear change detection signal for the start of changing up is present and there is no check-back signal indicating the position of the actuator for reducing the engine torque. The engine operating point is located in a range of the engine ignition map so as to be selected for emergency operation.
