摘要： A belt type continuously valiable transmission (CVT) comprises a pair of input pulleys, a pair of output pulleys and a belt trained over input and output pulleys to transmit power. Each pair of the pulleys has a hydraulic cylinder for pressing the pulleys against the belt. A line pressure used in one cylinder is controlled by adjusting an electric pressure regulating valve. A correction value is calculated which corresponds to the square of the rotational speed of the hydraulic cylinder to which line pressure is supplied. The value of control signal of the pressure regulating valve is corrected in accordance with the correction value, so that the error of the line pressure due to a centrifugal force is compensated for.

摘要： Method and apparatus for controlling an electromagnetic powder clutch connected to a vehicle engine and including a coil for engaging the powder clutch to transmit an output torque of the engine as a function of an electric current to be applied to the coil such that a variation in the engine torque is absorbed by a slip of the powder clutch. An optimum amount of slip of the powder clutch is determined based on a currently required engine output and a detected output speed of the clutch. A basic control value for controlling a magnitude of the electric current to be applied to the coil is determined based on the detected engine torque, such that the determined magnitude of the electric current permits engagement of the clutch so as to transmit the detected engine output torque. The basic control value is compensated for the determined optimum amount of slip of the clutch, thereby adjusting the transmission torque of the clutch so as to absorb the variation in the output torque of the engine.

摘要： A method and an apparatus of controlling an electromagnetic clutch incorporated in a power transmission system of a vehicle to transmit an output of an engine to the drive wheels of the vehicle is disclosed. An amount of electric current applied to the clutch is regulated to control an engaging action of said electromagnetic clutch, based on either a variation in rotating speed or torque of an output shaft of the electromagnetic clutch, or based on the frequency or number of variations per unit time in rotating speed or torque of the output shaft, as compared with the frequency or number of ignitions or combustions per unit time of the engine. In this way a variation in output torque of the engine is absorbed by the electromagnetic clutch for improved drivability, while a transmission power loss in the clutch is kept to a minimum for maximum fuel economy.
