A gearshift device comprises an input unit for receiving input data which is connected via at least one data line to a first controller via which an actuator unit can be controlled for setting a gearbox, especially an automatic gearbox of a motor vehicle, and comprising at least one second controller which is independent of the first controller. The second controller is separate from the first controller and is connected to the input unit via at least one data line. In the case of a fault in the first controller, the actuator unit can be controlled by the second controller at least partially correspondingly to the first controller.

Gearshift device

In a method for setting the output power of an internal combustion engine a resultant specified torque is determined from a driver-intended torque and at least tw o additional intended torques, and the resultant specified torque is set via a apparatus for adjusting torque. Each participant system, in addition to the intended torque, provides information regarding whether the intended constitutes a torque-increase or a torque-decrease. A processing block is provided for each participant system in which the particular intended torque is compared with the driver-intended torque and the resulting specified torque of the preceding participant system. From this, a resulting specified torque is determined. The priority of the particular torque requirement results from the sequence of the participant systems during processing.

Method for controlling the output power of an internal combustion engine

In a system for controlling the shifting of an automatic transmission, a selector device is controllable from a 'D' selected position into one of two shift positions for a stepwise shift limitation, by one gear at a time, manually. The respective upshift or downshift limitation can automatically be eliminated by fulfillment of a presettable condition, for example the expiration of a delay period.
