发明名称 Neutral control for vehicular automatic transmission
摘要 A friction apply device, from among each pair of friction apply devices that are applied to achieve a speed from first speed to fourth speed, that is to be placed in a slipping state is selected based on a heat load when a neutral control is executed. As a result, it is possible to continue to execute the neutral control without the durability of the friction apply device being impaired by the heat load, for example, thereby increasing a fuel efficiency effect and the like achieved by the neutral control.
