摘要：
A lockup clutch in a torque converter is connected by a lockup solenoid energized in response to a lockup signal generated by a lockup discrimination circuit. When a speed sensor detects a rate of deceleration higher than a predetermined level at the time the vehicle is abruptly braked, for example, a lockup control circuit overrides the lockup discrimination circuit to cut off the lockup signal for thereby de-energizing the lockup solenoid, whereupon the lockup clutch is disconnected.
