Abstract
An transmission control unit includes a sensor for detecting a vehicle condition, a traffic condition monitor for determining whether or not traffic is heavy, a transmission pattern selector, and a transmission controller. The traffic condition monitor adds or subtracts a predetermined value in response to vehicle speed detected at set intervals of time so as to provide a vehicle speed value. The heavier the traffic, the larger the additional value. Also, the lighter the traffic, the larger the subtractive value. The vehicle traffic value is used in order to determine how heavy the traffic is.
