Abstract:
A method for dynamically determining an intersection-torque for a drive line of a motor vehicle, the drive line of the motor vehicle having a motor drivingly connected with an uniaxial automatic transmission which is controlled by an electronic transmission mechanism, and the electronic transmission mechanism having a microprocessor with at least one program module for processing information and determining a desired intersection-torque;the method comprising the steps of:measuring a rotational speed of at least an output of the motor and an output of the automatic transmission (.omega.1, .omega.2) via sensors;using preset inertia moments (J1, J2, Jdrive) for determining the desired intersection-torque via a recalculation model, with the recalculation model utilizing the rotational speed of at least the output of the motor and the output of the automatic transmission (.omega.1, .omega.2) and the preset inertia moments (J1, J2, Jdrive).
