摘要： In a system for integrally controlling an automatic transmission and an engine, wherein hydraulic control devices are operated and engagement of frictionally engaging devices are selectively switched, to thereby achieve a shifting, and an engine torque is changed during shifting, a rate of change with time of oil pressure supplied to the frictionally engaging devices is temporarily reduced in association with the completion of the engine torque change. With this arrangement, rise of an output shaft torque generated at the time of completion of the engine torque change can be controlled, so that satisfactory shift characteristics can be obtained.

摘要： A primary regulator valve has a cutback port which regulates a line pressure to increase, at the first speed of D range, a throttle pressure is applied to the cutback port through a cutback valve. The primary regulator valve sets the line pressure from a line pressure port higher. The cutback valve has a spool which is compressed in one direction. A first control chamber which is connected to a hydraulic servo (for example, a second brake hydraulic servo) which hydraulic pressure is applied at more than the second speed is formed against the pressing direction, a second control chamber which is connected to a hydraulic servo (for example, a second-coast brake hydraulic servo) to limit a coasting condition of the second speed is so formed as to follow the above pressing direction. At the second speed of second range, the cutback valve, as the first speed of D range, the throttle pressure is applied to the cutback port. Furthermore, the primary regulator valve has a control chamber which regulates the line pressure to decrease. A pressure control valve (for example, a linear solenoid valve to control a lock-up clutch) is connected to the control chamber to reduce the line pressure when a manual valve is selected from N range to D or R range.

摘要： Hydraulic pressure which is regulated by a pressure control valve (linear solenoid valve) is applied to a hydraulic servo of a brake which is actuated when an engine-brake is effected. When the engine-brake is effected, a hydraulic pressure which is modulated by a modulator valve controlled by the linear solenoid valve is applied to the brake hydraulic servo. The pressure control valve provides high hydraulic pressure when vehicle speed is high based on signals from a speed sensor, and provides low hydraulic pressure when vehicle speed is low based on signals from the speed sensor, so that an engine-brake force is adequately controlled in accordance with vehicle speed. Furthermore, if a foot brake sensor is employed, the hydraulic pressure in accordance with vehicle speed can be made low when the engine-brake is effected with the foot brake applied. Based on signals from a front wheel rotation sensor and a rear wheel rotation sensor, the control unit calculates a rotational difference, so that the engine-brake force can be made low when the rotational difference is large.
