Arrangement for controlling motor vehicle automatic transmissions

摘要

The arrangement has a road gradient computation block, a desired speed computation block (47), a desired transmission ratio computation block (48) and a transmission ratio operating command output block (49) for computing a command value using the revolution rates of input and output side rotation elements and the demand value of the transmission ratio computed in the desired transmission ratio computation block. An Independent claim is also included for a method of controlling motor vehicle automatic transmissions.
