Abstract
An automated clutch (16) control and calibration method. Clutch control parameter values (TP and AP) corresponding to the clutch touch point condition and the approach point condition, respectively, are determined and are utilized to control reengagement of the automated clutch. While awaiting reengagement, the clutch is caused to assume and dwell in the approach point condition.
Claims13
A method for controlling an automated vehicular master friction clutch (16) drivingly interposed between an engine (14) and an input shaft (52) of a multiple-speed transmission (12), said clutch having an approach point condition, said method characterized by:
- (a) determining a value (AP) of said clutch control parameter indicative of said clutch being at the approach point condition thereof;
- and
- (b) after disengaging said clutch and while awaiting a clutch engagement command, causing said clutch to assume and remain in the approach point condition thereof.
A control system for controlling an automated vehicular master friction clutch (16) drivingly interposed between an engine (14) and an input shaft (52) of a multiple-speed transmission (12), said clutch having an approach point condition, said control system characterized by:
- means for determining a value (AP) of a clutch control parameter indicative of said clutch being at the approach point condition thereof;
- and
- means effective, after disengaging said clutch and while awaiting a clutch engagement command, for causing said clutch to assume and remain in the approach point condition thereof.
A method for controlling an automated vehicular master friction clutch (16) drivingly interposed between an engine (14) and an input shaft (52) of a multiple-speed transmission (12), said clutch having a touch point condition and an approach point condition, said method characterized by:
- (a) determining a first value (TP) of a clutch control parameter indicative of said clutch being at the touch point condition thereof;
- (b) determining a second value (AP) of said clutch control parameter indicative of said clutch being at the approach point condition thereof;
- and
- (c) after disengaging said clutch and while awaiting a clutch engagement command, causing said clutch to assume and remain in the approach point condition thereof.
