Method and system for the regulation and/or control of an engine gearbox unit in a motor vehicle
First Claim
1. A method for regulating and/or controlling an engine-transmission unit in a motor vehicle, comprising:
- in a function unit connected to a controller, prioritizing torque demands from torque demands generated by a plurality of demanders to obtain an only torque value;
storing the only torque value as a current successful situation and retaining the torque value for use in a future process as a previous successful situation;
processing the torque value of the current successful situation as well as the torque value of a previous successful situation to comparable torque values in each case required for the implementation of the demands;
in the event of a priority change when the current successful situation is different from the previous successful situation, changing a desired torque demand at driving wheels of the motor vehicle from the torque value of the previous successful situation to the torque value of the current successful situation;
sending the desired torque demand to an electronic controller; and
carrying out the desired torque demand by controlling at least one of engine parameters and a ratio of a transmission unit.

Abstract
A method for regulating and/or controlling an engine-transmission unit in a motor vehicle includes prioritizing torque demands to obtain an only torque value, storing the only torque value as a current successful situation and retaining the torque value for the previous successful situation, and processing the torque value of the current successful situation as well as the torque value of the previous successful situation to comparable torque values in each case required for the implementation of the demands. The method farther includes changing a desired torque demand at driving wheels of the motor vehicle from the torque value of the previous successful situation to the torque value of the current successful situation in the event of a priority change when the current successful situation is different from the previous successful situation, sending the desired torque demand to an electronic controller, and carrying out the desired torque demand by controlling at least one of engine parameters and a ratio of a transmission unit.

14. A system for regulating and/or controlling an engine-transmission unit in a motor vehicle, comprising:
-
the controller having an input side; the function unit connected to the input side of the controller, wherein the functional unit is programmed to perform the steps of prioritizing torque demands from torque demands generated by a plurality of demanders to obtain an only torque value; storing the only torque value as a current successful situation and retaining the torque value for use in a future process as a previous successful situation; processing the torque value of the current successful situation as well as the torque value of a previous successful situation to comparable torque values in each case required for the implementation of the demands; in the event of a priority change when the current successful situation is different from the previous successful situation, changing a desired torque demand at driving wheels of the motor vehicle from the torque value of the previous successful situation to the torque value of the current successful situation; and sending the desired torque demand to the controller; wherein the controller is programmed to carry out the desired torque demand by controlling at least one of engine parameters and a ratio of a transmission unit. - View Dependent Claims (15, 16, 17)
