Shift controls for automated shifting manual transmissions |
摘要 |
<p>An automated shifting system for a manual transmission having a neutral clutch connecting an engine to a multiple ratio transmission, the transmission having servo operated gear shift mechanism. A driver-controlled gear shift switching mechanism is used to activate the servos that effect ratio range changes. A gear shift switching mechanism includes multiple switches for triggering operation of the servos that control the ratio range changes. A range sensing redundancy strategy for the ratio range switches provide improved protection against an unintended change in direction due to three-bit separation between bits of the valid codes and to a range sensing swit.ch failure strategy by identifying when a range change commanded by the driver exhibits a single-point fault condition. A fault condition due to a single-point sensing switch failure is identified even in those instances when a range change commanded by the driver allows continued normal control system operation, although the driver is notified of the failure by a system warning device. <IMAGE></p> |
