ANZEIGE UND FEHLERINDIKATOR FUER EINE HALBAUTOMATISCHE STEUERUNG EINES MECHANISCHEN GETRIEBES.

摘要

A transmission system (10) including a control display (2, 302) is provided. The control display comprised of three sections, a currently engaged gear ratio section (2''') a maximum permissible consecutive upshift indicating section (2 min ) and a maximum permissible consecutive downshift indicating section (2 sec ). The central processing unit (38) includes circuitry and logic rules to process input signals to determine the currently permissible gear ratios and will indicate said gear ratios, in the form of maximum permissible upshifts and downshifts, at said display. The central processing unit also includes circuitry and logic rules to sense the existence of a fault condition, to assign a predetermined code ("18") thereto and to issue command output signals to the display to cause the second and third sections to assume a fault condition indicating display and to cause said first section to display to assigned code.
