Abstract (en)
[origin: WO9710965A1] A method for limiting the input torque of an automatic transmission provided with a hydraulic torque converter and combined with a drive engine, wherein the converter speed ratio i = omega T omega m is continuously determined on the basis of measurements of the converter turbine speed omega T and the engine speed omega m, a maximum value omega m<lim> for the engine speed omega m is defined for each value of i, which maximum value must not be exceeded if the transmission is not to be overloaded, and the sign and amplitude of the quantity DELTA omega m<lim>(i) = omega m<lim>(i) - omega m are monitored.
