摘要： Hydraulic control system and method for an automatic transmission. The hydraulic control system includes a hydraulic pressure source, a flow rate control valve having a spool with an orifice and a drain hole, stroke position determining means, and pressure regulator means. The stroke position determining means determines that the spool is displaced from a large spool-stroke position where a communication area of the drain hole is not less than a first predetermined area, to a small spool-stroke position where the communication area is not more than a second predetermined area. The pressure regulator means regulates a hydraulic oil pressure downstream of the orifice and corrects the hydraulic oil pressure downstream of the orifice by adding a predetermined correction amount for a first predetermined time when the stroke position determining means determines that the spool is displaced from the large stroke position to the small stroke position.

摘要： During a downshift of a belt-drive continuously variable transmission, occurring owing to vehicle deceleration, a CVT controller foretells that a slippage between a drive belt and each of primary and secondary variable-width pulleys tends to occur, when a primary pulley pressure is less than a first predetermined pressure level and a primary pulley speed is less than a first predetermined rotational speed. When the belt slippage has been foretold, the CVT controller inhibits the primary pulley pressure from dropping by setting an actual transmission ratio calculated before a set time period from a time when the slippage has been foretold or a transmission ratio of a relatively higher speed side as compared with a ratio-change operating state obtained when the slippage has been foretold, to a desired transmission ratio, or by relatively rising a line pressure as compared with a line pressure level produced when the slippage has been foretold.

摘要： In a V-belt type CVT, an actual-shift-ratio corresponding operated position of a step motor is calculated through conversion of an actual shift ratio expressed by the rotational-speed ratio between primary and secondary pulleys. A displacement amount is calculated between the actual-shift-ratio corresponding operated position of the step motor and an actual position thereof. A correction amount of the line pressure is calculated to reduce the displacement amount, and the line pressure is corrected in accordance therewith.

摘要： A shift control system for obtaining a smooth shift feeling in a shifting necessitating redeployment of friction elements. The shift control system is comprised of a sensor which detects a state that disengagement pressure of a friction element to be disengaged almost becomes zero during shifting. In reply to the detection of the sensor, a controller adjusts engagement pressure of the other friction element to be engaged at a predetermined value determined according to input torque and gear ratio.

摘要： There are provided with a determination means for determining whether or not the correlation between the pressure value detected by the primary pressure sensor and the pressure value detected by the secondary pressure sensor is an actually impossible relation (Step 5), and a switchover means for switching over to an open control while prohibiting a feedback control when the correlation is determined to have become a relation actually impossible by the determination means (Step 6). Presence or absence of a fault to the primary pressure sensor or the secondary pressure sensor (particularly, fault of fixed output voltage) is judged based on the correlation between the output voltage of the primary pressure sensor and the output voltage of the secondary pressure sensor to prohibit the control of a primary pressure and a secondary pressure using the hydraulic pressure sensors when it is judged that there is a fault.

摘要： A shift control system in an automatic transmission controls a shifting which necessitates redeployment of friction elements so that one friction element is engaged while the other friction element is released. In reply to a shift command, the shift control system starts to control one of the engagement pressure of the friction element to be engaged or the disengagement pressure of the friction element to be disengaged. Next, the shift control system starts to control the other one of the engagement pressure or the disengagement pressure at a moment at which a preset time has elapsed from the start of the shift command. The preset time is corrected so as to decrease a physical quantity indicative of discord of the timing between the engagement and the disengagement. Accordingly, the preset time firmly takes a proper time so as to carry out the deployment of both friction elements at a synchronized point due to such a learning control. This enables the shift feeling to always be kept good.

摘要： A downshift control in an automatic transmission is disclosed wherein magnitude of servo activating hydraulic fluid pressure is temporarily decreased as a function of vehicle speed when the automatic transmission effects a downshift from a current gear ratio to a new gear ratio. Owing to this arrangement, a fluid operated frictional device associated with the current gear ratio is released quickly without any lag to allow quick increase in engine speed during the downshift with the throttle fully opened at a high vehicle speed, i.e., a power-on downshift at high vehicle speed.
