Title: Control method for automatic starting clutch
Inventor: TANIJIRI HIROYUKI
IPC: B60W10/101
Filed: 1987-11-06
Abstract: PURPOSE:To eliminate breathing feeling in the process of startingby keeping transmission capacity constant regardless of an engagement characteristic of a starting clutch during the period between a point of time the engine speed takes the maximum value and the clutch connection enable state. CONSTITUTION:An electronic control device 60 reads engine speed Nin when starting control is started to be compared with the maximum engine speed No where there is the possibility of engine stall. In case of Nin<=NO, the control device outputs a duty ratio corresponding to Nin to a control solenoid 48 to control a starting clutch 20 through a starting control valve 47. After that, in case of Nin>NO, it is discriminated whether the time change rate dNin/dt is positive or negative. As the time change rate is always on the positive side at the beginning of starting, a duty ratio corresponding to Nin is output, and when the engine speed Nin starts decreasing, it comes to the negative side. At this time, the update duty ratio is kept to keep clutch oil pressure until the completion of connection of the starting clutch 20. In case of Nin<NO, it returns to ordinary stating control.
