Abstract
A vehicular lockup clutch-equipped transmission control apparatus is applied to a vehicle that includes a heater apparatus for heating a cabin by heat from an engine, a transmission that transfers power between the engine and a wheel, and a heat exchanger that conducts heat exchange between the engine and the transmission. The control apparatus controls a lockup clutch that is disposed between the engine and the transmission and that mechanically connects and disconnects a path of power, in accordance with a state of operation of the vehicle. The control apparatus includes a controller that determines whether a heating capability requested of the heater apparatus is at least a first predetermined level based on parameter related to a temperature inside the cabin. If it is determined that the heating capability requested of the heater apparatus is at least the first predetermined level, the controller restricts engagement of the lockup clutch.
