    摘要： A torque converter (1) connecting an engine (14) and a transmission (15) of a vehicle is provided with a lockup clutch (2), and a controller (5) is programmed to increase an engagement force of a lockup clutch (2) under open loop control before shifting to feedback control of the engaging force using a target slip rotation speed. When an engine output torque rapidly decreases during open loop control (S59, S60), the controller (5) decreases the engaging force according to a variation amount of the engine output torque (S61, S65), thereby preventing an unintentional sudden engagement of the lockup clutch (2) due to decrease in the engine output torque.

    摘要： A system for controlling stall speed for an electromagnetic clutch having a magnetizing coil for engaging a crankshaft of an internal combustion engine with an input shaft of a transmission of a vehicle. A transistor switching circuit for allowing clutch current to flow through the magnetizing coil, and an electric circuit for producing pulses dependent on ignition pulses of the engine are provided for intermittently turning on the transistor for energizing the coil. A circuit including a time constant circuit and a switching transistor is provided for decreasing duty ratio of the pulses and for decreasing the clutch current. Switches are provided for detecting a heavy load condition at starting of the vehicle and for producing an output signal. The output signal is latched by a flip-flop and applied to the switching transistor thereby to decrease the duty ratio of the pulses for decreasing the clutch current with respect to the engine speed.

    摘要： A system is provided which controls the pressure with which a clutch engages, utilizing a slip rate of the clutch which is equal to the ratio of the rotational speed of the output shaft to the rotational speed of the drive shaft thereof as a main parameter. A microprocessor reads a throttle opening and the slip rate at a time interval of 0.4 sec from the initiation of the clutch engagement, and accesses a particular group of clutch engagement controlling data which correspond to the time l elapsed and to these parameters. The controlling signals of the particular group are sequentially outputted to the clutch energizing device at a subinterval of 0.05 sec during the time interval of 0.4 sec. The interval changes from l=0 to l=8 at maximum, from the initiation to the completion of the clutch engagement. Each interval l=0 to l=8 corresponds to 0.4 sec. Whenever a temporary clutch activation is instructed, the microprocessor increases the subinterval of 0.05 sec to 0.1 sec and the time interval l to 0.8 sec. The value of l is incremented by one after a time length of either 0.4 or 0.8 sec elapses.
