Title: Method and device for clutch control
Inventor: KONO KOZO
IPC: B60W10/04
Filed: 1989-03-27
Abstract: PURPOSE:To control a clutch smoothly and precisely and shorten dead time for torque transmission by outputting electric signals with time variation characteristics of target stroke for engaging a clutch in response to command for engaging clutch, and controlling the stroke of the clutch according to the signals. CONSTITUTION:A basic data generator 6 outputs electric signals with time variation characteristics of target stroke for engaging a clutch 2, in response to command signal CM for engaging clutch. A proper target stroke pattern data BD in response to the clutch engagement command from a transmission control unit 7 and according to the present gear position is output from the basic data generator 6, and corrected in a correction calculator 8 according to the present amount of accelerator control. Variation of the pattern of variation in the amount of stroke or the clutch 2 is determined by offset of the amount of control of an accelerator pedal 9. Therefore, the larger the amount of control of the accelerator pedal 9 becomes, the smaller the target stroke value at the beginning point of the engagement of the clutch 2 becomes, and a time required for completed engagement of the clutch 2 is shortened.
