<p>PURPOSE:To positively perform a lock-up operation at the time of deceleration to improve fuel cost by detecting deceleration of the car speed to increase generated voltage and to perform lock-up fastening, and limiting the increase in generated voltage of an alternator for a specified time. CONSTITUTION:An electronic control unit 7 is connected to a hydraulic circuit 6 for driving an automatic transmission 4 having a lock-up mechanism 5, and output voltage of an alternator 9 mounted to an engine 1 is controlled by the electronic control unit 7. A throttle opening sensor 10 and an engine speed sensor 11 are connected to the electronic control unit 7. When the engine speed is reduced from a specific engine speed to an idling engine speed, lock-up fastening is performed, and the lock-up fastening is released before the idling engine speed is reached. On the other hand, for alternator-power generation, generated power is decreased except for the time of deceleration generated power is increased only at the time of deceleration, and the increase in alternator- generated power is delayed for a specified time from the start of deceleration.</p> |
