Abnormal-period automatic shift control apparatus of automated manual transmission

Abstract

In an abnormal-period automatic shift control apparatus of an automated manual transmission (AMT), a controller includes a first state detecting section configured to detect whether the AMT is in a first state where the AMT is thrown into a shift stage during an engine starting period, and a second state detecting section configured to detect whether the AMT is in a second state where a clutch failure that an automatic clutch, employed in the AMT for engine power transmission, remains engaged undesirably, occurs. Also provided is a neutral-range-period abnormality countermeasure section configured to inhibit a supply of working oil from an engine-drive oil pump, serving as a working medium for automatic-clutch engagement-and-disengagement control and automatic gear shifting, for preventing an automotive vehicle from beginning to move, while a selected operating range is a neutral range, under a condition where the first and second states occur simultaneously.

1 . An abnormal-period automatic shift control apparatus of an automated manual transmission, comprising:
 a controller comprising:
 (a) a first state detecting section configured to detect whether the automated manual transmission is in a first state where the automated manual transmission is thrown into a shift stage during an engine starting period; 
 (b) a second state detecting section configured to detect whether the automated manual transmission is in a second state where a clutch failure that an automatic clutch, employed in the automated manual transmission for engine power transmission, remains engaged undesirably, occurs; and 
 (c) a neutral-range-period abnormality countermeasure section configured to inhibit a supply of working oil from an engine-drive oil pump, serving as a working medium for automatic-clutch engagement-and-disengagement control and automatic gear shifting, for preventing an automotive vehicle from beginning to move, while a selected operating range is a neutral range, under a condition where the first and second states occur simultaneously. 
   
     
     
         2 . An abnormal-period automatic shift control apparatus of an automated manual transmission, comprising:
 a controller comprising:
 (a) first state detection means for detecting whether the automated manual transmission is in a first state where the automated manual transmission is thrown into a shift stage during an engine starting period; 
 (b) second state detection means for detecting whether the automated manual transmission is in a second state where a clutch failure that an automatic clutch, employed in the automated manual transmission for engine power transmission, remains engaged undesirably, occurs; and 
 (c) neutral-range-period abnormality countermeasure means for inhibiting a supply of working oil from an engine-drive oil pump, serving as a working medium for automatic-clutch engagement-and-disengagement control and automatic gear shifting, to prevent an automotive vehicle from beginning to move, while a selected operating range is a neutral range, under a condition where the first and second states occur simultaneously.
