摘要： A continuously variable transmission in a motor vehicle is regulated using a controller comprising a first control circuit as a speed controller for regulating the transmission input speed as the product calculated from the transmission output speed and the transmission ratio, complete with a summation element at the controller input as well as with a control element, and a second control circuit post-connected to the first control circuit as a speed gradient controller for regulating the time derivative of the transmission input speed, complete with a summation element at the controller input. To preset a variable control response of the controller, different filter functions are defined, in relation to the operating conditions of the motor vehicle, as a fixed relationship between the input quantity control deviation as the difference calculated from nominal and actual values of the transmission input speed and the output quantity nominal gradient value of the transmission input speed, and fed to the control element of the first control circuit, which control element has been designed as a filter element. Depending on the current operating conditions of the motor vehicle, and using of the predefined filter functions, the filter element generates a filter function used as a current filter function. The function values of the current filter function are fed as filter values and as a reference magnitude from the filter element to the summation element at the controller input of the second control circuit.

摘要： A procedure to control the drive unit in motor vehicles wherein: the maximum engine performance characteristic is determined; as a minimum engine performance characteristic, a reference performance characteristic is specified by how drive resistance depends on vehicle speed at a medium payload of the motor vehicle; above the reference performance characteristic, a first performance characteristic which is dependent on actual driving speed is defined and allocated a minimum assessment value; between this first performance characteristic and the maximum engine performance characteristic, a second performance characteristic which is also dependent on actual driving speed is defined and allocated a maximum assessment value; the current engine performance is determined; current assessment values are determined by comparing current engine performance to the first performance characteristic and the second performance characteristic; the current assessment values, as continuously determined, are filtered over time in this way, filtered assessment values are obtained; and these filtered assessment values are used to select drive unit control parameters, or parameter sets, which then are used to control the drive unit.
