  • Engine torque error learn during dynamic vehicle test
    Publication number: 20060264298
    Abstract: A method of regulating gear shifts of a transmission driven by an engine includes calculating a first torque error and calculating a second torque error. A compensation torque is determined based on the first torque error and the second torque error. The gear shifts are regulated based on the compensation torque.

  • Torque converter clutch release to prevent engine stall
    Publication number: 20060116236
    Abstract: A torque converter control system for a vehicle includes a torque converter having a torque converter clutch (TCC) that selectively couples an engine and a transmission for common rotation. A control module regulates the TCC between an engaged state and a disengaged state. The control module monitors an output shaft signal of the transmission and detects rapid deceleration of the vehicle based on the output shaft signal. The control module switches the TCC to the disengaged state when rapid deceleration is detected.
