Method of and apparatus for controlling a continuously variable automatic transmission

The method involves performing a transmission ratio regulator operation by determining a desired transmission ratio and a desired engine torque while the regulated transmission variable is changed, such that the determined actual transmission ratio corresponds to the calculated desired transmission ratio. A torque regulator operation is performed by determining a corrected desired engine torque with one of the predefined regulated transmission variable and a corrected desired transmission output torque, in conjunction with a change of the regulated transmission variable for controlling the rotational engine speed. An Independent claim is also included for a control apparatus for continuously variable automatic transmission.
