EFFECTIVE DRIVELINE VIBRATION DETECTION ALGORITHM IN TRANSMISSION TCC SLIP CONTROL |
摘要 |
A method for adjusting the slip of a torque converter for a plurality of selected engine speeds, transmission gears and engine torque. A sensor is used to determine vibrations transmitted through the torque converter to the driveline of the vehicle. The sensor signal is sent to a controller where it is converted to the frequency domain. If the amplitude of the frequency signal exceeds a threshold, then the algorithm increases/decreases the converter slip until the dhveline vibrations equal a threshold. |
