摘要： A hydraulic control device for an automatic transmission is provided. The hydraulic control device can sets up any gear from a plurality of gears by causing any one of a plurality of frictional engagement elements to selectively carry out an engagement operation. The hydraulic control device includes: a regulator valve that regulates base oil pressure of hydraulic oil supplied from an oil pressure source; a relief valve provided in a lubricating oil passage connected from the regulator valve; and a line pressure switching section that sets up line pressure to low pressure to reduce the amount of lubricating oil in a region in which engagement hydraulic oil pressure does not require high engagement hydraulic oil pressure depending upon an operation state of a vehicle, and sets up the line pressure to high pressure when a target value of the engagement hydraulic oil pressure exceeds predetermined pressure.

摘要： A spool valve includes a groove defined in the spool and a notch. A line A is drawn to extend through a communication zone a provided upon communication of the notch which is disposed at a distal end of the line A and defined in a step of a spool with an input port to form a 69° angle with respect to an L-axis. Fluid flowing into the groove through the communication zone a upon communication of the notch with the input port, does not collide with other portions of the spool before colliding with a bottom of the groove. Therefore, the flow of the fluid along the L-axis causes a flow force applied to the spool to be suppressed resulting in a decreased load on an actuator. The notch makes it is possible to ensure the stable operation of a spool valve, while preventing the self-induced vibration of the spool.

摘要： A lockup control system controls a lockup state of the automatic transmission employing a torque converter with a lockup clutch. The lockup control system executes a lockup clutch engagement pressure control for decreasing an engagement differential pressure of the lockup clutch at a predetermined differential pressure for a predetermined time period under a coast lockup state. Further, the lockup control system executes a learning control for obtaining the predetermined differential pressure by adding a differential pressure correction value to a differential pressure learning value by which the torque converter generates a slight slip under the coast lockup state. Therefore, even during the coast lockup state, both of suppressing vibrations by a lowering of a lockup capacity and maintaining a responsibility for re-increasing the differential pressure are ensured.

摘要： An automatic control system for a multiple ratio transmission includes an electronically controlled variable orifice configuration within a discharge circuit for a downshift control system from a high speed ratio to an intermediate speed ratio. The variable orifice configuration divides the discharge circuit into an upstream part communicating with an accumulator chamber of an accumulator and an intermediate brake release pressure chamber defined by a double acting piston of an intermediate ratio brake servo, and a downstream part communicating with a high speed ratio clutch. A calibrated flow control orifice is disposed in the discharge circuit to control discharge flow of oil from said downstream part. A transmission controller reduces the variable orifice configuration to provide a reduced orifice size during inertia phase of the downshift.

摘要： A lock-up control apparatus and method for a torque converter of an automatic power transmission associated with a vehicular internal combustion engine driven in a plurality of engine driving modes, such as a lean burn mode. A lock-up region of a map for the torque converter is modified toward a higher vehicle speed when the engine operates in one of the driving modes such that an engine output torque value becomes large under the same engine load conditions as those when the engine is driven in any one of the other driving modes in which the engine output torque is small. The lock-up region is extended up to a higher engine load region when the engine operates in one of the driving modes such that the engine output torque is small under the same load condition.

摘要： Under a higher speed gear position of the transmission, a control valve can drain a hydraulic pressure of a forward clutch to cause the forward clutch to take a disengaged condition. With this, undesired friction of a forward one-way clutch under such higher speed gear position is suppressed. A fail-safe system is employed for recovering an engaged condition of the forward clutch even when the control valve is stuck at such pressure draining position.
