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 (M, G) in a motor vehicle, comprising:
- in a function unit (MASTER) connected to a controller (CTRL), prioritizing torque demands (S_WI, S_XX, . . . , S_AC, S_XY) of demanders (M_XX, . . . , M_XY) to obtain an only torque value;
storing the only torque value as a current successful situation (S_ZZ_PRIO) and retaining the torque value for the previous successful situation (S_ZZ_PRIOOLD);
processing the torque value (for example, S_XX) of the current successful situation (S_ZZ_PRIO) as well as the torque value (for example, S_XY) of the previous successful situation (S_ZZ_PRIOOLD) to comparable torque values in each case required for the implementation of the demands (S_XX;
S_XY);
in the event of a priority change when the current successful situation (S_ZZ PRIO) is different from the previous successful situation (S_ZZ_PRIOOLD), changing a desired torque demand at driving wheels (R) of the motor vehicle from the torque value (M WHEEL_DESIRED=M_WHEEL_XY) of the previous successful situation (S_ZZ PRIOOLD) to the torque value (M_WHEEL_DESIRED=M_WHEEL_XX) of the current successful situation (S_ZZ_PRIO);
sending the desired torque demand (M_WHEEL_DESIRED) to an electronic controller (CTRL); and
carrying out the desired torque demand by controlling at least one of engine (M) parameters and a ratio of a transmission unit (G).

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.
