Abstract: A speed change control system for an automatic transmission for making a speed change of the automatic transmission by applying/releasing frictional engagement elements and for controlling a line pressure, to be fed to the frictional engagement elements, to a pressure according to a throttle opening. The speed change control system detects a downshift of the automatic transmission with the throttle opening being increased, to control the line pressure to a level lower than that according to the throttle opening, if the downshift is detected. As a result, the torque transmission capacities of the frictional engagement elements, even if they are of the hydraulic type in which they are applied at the downshift, can be preventing from increasing during the speed change, thereby to improve the shift shock at the downshift.

Abstract: An oil pressure control system for an automatic transmission in which an initial pressure of oil pressures to be fed selectively to apply frictional engagement elements is controlled according to an engine load. The control system comprises an oil pressure keeper for keeping the initial pressure during a shift at a constant level independent of the engine load. Thus, the rates of feeding the oil pressures to the frictional engagement elements are constant so that the shift shock is suppressed to reduce the factors for the oil pressure fluctuation thereby to facilitate the control.

Abstract: This hydraulic pressure transmission control device is for a vehicle with a transmission system which has, in series in the specified order in the rotational force transmission path, a first transmission mechanism which can be set to any one of several speed stages according to selective supply of hydraulic fluid pressures, and a second transmission mechanism which similarly can be set to any one of several speed stages according to selective supply of hydraulic fluid pressures. It includes a first hydraulic fluid pressure control device which has a first line pressure control valve for supplying it with a first line pressure for being then selectively supplied to the first transmission mechanism as its selective supply of hydraulic fluid pressures; and a second hydraulic fluid pressure control device which has a second line pressure control valve for supplying it with a second line pressure for being then selectively supplied to the second transmission mechanism as its selective supply of hydraulic fluid pressures. Thereby the first and second line pressures can be independently determined according to circumstances. Particularly, the second line pressure control valve may increase the line pressure which it supplies, the lower is the engaged speed stage of the first transmission mechanism, and/or the lower is the engaged speed stage of the second transmission mechanism, and/or the higher is the value of a parameter representing the load on the engine.

Abstract: An apparatus and a method control a belt-type continuously variable transmission of a vehicle having a continuously variable speed ratio, which is a ratio of a rotation speed of an input shaft to a rotation speed of an output shaft. The speed ratio of the transmission is controlled by changing a groove width of each of the pulleys, and a belt clamping pressure applied to at least one of the pulleys to clamp the torque transfer belt also is controlled. Furthermore, the speed ratio of the transmission is set to a low-load speed ratio when it is determined that control of the belt clamping pressure has failed and the belt clamping pressure is raised to a high level. The low-load speed ratio is predetermined so that a load applied to the torque transfer belt is substantially minimized.

Abstract: A control apparatus is provided in a vehicle equipped with a power source and a continuously variable transmission. The continuously variable transmission is connected to the power source. The control apparatus includes a target power determinator, a target revolutions determinator, a determining device, a setting device and a target torque determinator. The target power determinator determines a target power of the power source. The target revolutions determinator determines target revolutions on the basis of the target power. The determining device determines whether the vehicle is a transient driving condition or not. The setting device sets the target revolutions as setting revolutions when the determining device determines that the vehicle is not in the transient driving condition. The setting device sets revolutions different from the target revolutions as the setting revolutions when the determining device determines that the vehicle is in a transient driving condition. The target torque determinator determines a target output torque of the power source on the basis of the target power and the setting revolutions. Since the vehicle is controlled in accordance with the driving condition of the vehicle, a jerky feeling can be avoided and ride quality or drivability of the vehicle is prevented from being deteriorated, even when the vehicle is in a transient driving condition.
