AUTOMATIC TRANSMISSION AND ENGINE CONTROL SYSTEM |
摘要 |
In order to determine a malfunction which results in the loss of torque reduction control, the engine speed and the torque converter characteristics are monitored when a torque down signal is issued. The maximum engine torque which should be produced under such circumstances is used to derive a corresponding maximum engine speed value. If the actual engine speed exceeds the estimated value, appropriate torque down control can be assumed to have been lost. In response a fail safe such as boosting line pressure to switching to an alternative source of torque control can implemented. A suitable warning signal can also be generated.
