    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.

    摘要: System is provided for controlling the pressure with which a clutch is engaged, with the throttle opening and the rotational speed of a driven shaft of the clutch. A microprocessor reads a throttle opening and the rotational speed of the driven shaft of the clutch at a time interval of 0.4 sec, and accesses a particular group of controlling data which control the clutch engagement and which are grouped together as a function of a time lapse l as well as the read values of these parameters. During the interval of 0.4 sec, the microprocessor sequentially outputs the controlling data of the particular group with a time subinterval of 0.05 sec. The system detects a difference between the last data of a preceding particular group and the first data of a subsequent particular group at the renewal of the data group and then corrects subsequent data for controlling clutch control pressure so as to smooth the change of the clutch control pressure.

    摘要: System is provided for controlling the pressure with which a clutch is engaged, with a slip rate e of the clutch, which is equal to the ratio of the rotational speed of a drive shaft thereof, as a main parameter. A microprocessor reads a throttle opening and the slip rate e from the initiation of engagement of the clutch at a time interval of 0.4 sec, and accesses a particular group of controlling data which control the clutch engagement and which are grouped together as a function of a time lapse l as well as the read values of these parameters. During the interval of 0.4 sec, the microprocessor sequentially outputs the controlling data of the particular group with a time subinterval of 0.05 sec. The time interval includes subintervals corresponding to l=0 to l=8 at maximum, from the initiation to the completion of the clutch engagement. Each subinterval l=0 to l=8 spans 0.4 sec. When a temporary clutch activation is instructed, the microprocessor changes the length of the subinterval from 0.05 to 0.1 sec, and also changes the time interval l to 0.8 sec. When the slip rate e is low at the initiation of the clutch engagement, a group of controlling data is selected which is to be assigned to a first subinterval l=0 corresponding to the deceleration of the clutch drive shaft.
