摘要： A range determination apparatus for preventing a shift range from being undefined during speed change states of an automatic transmission with no manual valve. The range determination apparatus includes a gear speed change mechanism and a plurality of friction engagement elements operative to have respective operation states changed between an engagement and a disengagement state. The range determination apparatus is used for automatic transmissions subject to speed changes via a torque transmission path of the gear speed change mechanism changed by the operation states of the friction engagement elements. A real shift range determination is carried out on the basis of the operation states of the friction engagement elements, where a T-ECU is operative to determine a current shift range based on detection results obtained by oil pressure sensors and operation patterns preliminarily memorized when the operation states of the friction engagement elements are not being changed.

摘要： A control apparatus for an automatic transmission prevents friction engagement elements from being kept in an engagement state in accordance with the traveling state of a vehicle when a shift lever is operated to the position where a neutral range is formed, even if the malfunction of a solenoid valves occurs. If the shift range is switched to an N range, an ECU controls an So3 solenoid valve to enter an energized state, and controls a speed change mechanism to enter a non-transmission state, when the ECU judges that vehicle speed V is smaller than an N range forming method changing threshold Vn. The ECU controls an SL1 linear solenoid valve to enter a de-energized state, and controls the speed change mechanism to enter the non-transmission state, when the ECU judges that the vehicle speed V is no less than the N range forming method changing threshold Vn.

摘要： A shift-by-wire control system includes a parking lock device that brings an output shaft of an automatic transmission device to a lock state when a range switching unit switches to the P-range. The parking lock device brings the output shaft to a lock-release state when the range switching unit switches to another shift range. An electric motor actuates the range switching unit and the parking lock device in accordance with an instruction of an operator. A manual device transmits manual operation force of the operator to the parking lock device when the electric motor stops. The manual device includes a one-way transmission unit permitting transmission of the manual operation force in a direction toward the lock state, and prohibiting transmission of the manual operation force in a direction toward the lock-release state.

摘要： A control apparatus for a range changeover device checks whether an actual range agrees with a target range. If the actual range differs from the target range, the control apparatus performs vehicle driving force restriction control irrespective of a presence/absence of abnormality in a range changeover operation. The control apparatus may restrict an engine output power by closing a throttle valve of the engine to around an idle position, thereby restricting the vehicle driving force.
