<p>The system of automatic gearbox control uses known devices and controls and electronic circuits of a closed loop variety to: (a) release the clutch; (b) immobilise the gearbox; (c) to put in a memory the selected speed and other information and operate clutch and gearbox appropriately thereafter. Both the gearbox and clutch are electrically operated. The gearbox change order may be suppressed and the memory cleared to allow a new ratio selection either manually, by "kick-down" on the accelerator, by an automatic device operating when the engine operates below a set level, completely automatically or semi-automatically.</p> |
