Abstract
A transmission includes a transmission output speed (TOS) sensor providing a signal indicative of an output speed of the transmission. A controller estimates an actual torque output of the transmission and determines, in real time, a first TOS acceleration based on the signal provided by the transmission output speed sensor and a second TOS acceleration based on the actual torque estimation. The first and second accelerations are compared and a torque transient trigger is activated when the divergence exceeds a threshold value.
