Abstract:
1. A power transmitting apparatus comprising: a torque converter having a torque amplifying function; a clutch adapted to be positioned in a first power transmitting condition in which a driving power of an engine is transmitted to driving wheels via a power transmitting system of the torque converter and a second power transmitting condition in which the driving power of the engine is transmitted to the driving wheels not via a power transmitting system of the torque converter; an oil pump driven by the driving power of the engine to supply oil to the clutch and to the torque converter to operate them; a clutch control device configured to for arbitrarily and selectively operating the clutch in accordance with a condition of a vehicle to position the clutch either in the first power transmitting condition or the second power transmitting condition; and an engine control device for transitioning the engine to an idle-stopped condition by automatically stopping the engine subject to the reduction of vehicle speed below a predetermined value and for restarting the engine subject to the release of a braking operation under the idle-stopped condition or the depression of the accelerator pedal; a linear solenoid for controlling a clutch pressure which is a pressure of oil applied to the clutch; and a selector valve for selecting whether the clutch pressure controlled by the linear solenoid should be applied to the clutch characterized in:
