Method for controlling vibrator in car, involves calculating ratio of optimal according to measured parameter, and comparing engaged gear ratio with ratio of optimal box, where vibrator is controlled based on result of comparison

摘要

The method involves acquiring an engaged gear ratio and acquiring a characteristic parameter of an operating point of an engine. A ratio of optimal box is calculated according to the parameter. The engaged gear ratio is compared with the ratio of the optimal box. The vibrator is controlled based on the comparison result. The vibrator is controlled with an idle state when a committed ratio of the box is equal to the ratio of the optimal box and controlled with an active state when the committed ratio of the box is different to the ratio of the optimal box over a limited duration.
