INTEGRATED C.V.T. CONTROL SYSTEM
This paper describes the control system developed by LVL in association with and for the operation of the recently announced commercial vehicle continuously variable transmission (CVT). The system specification, construction and testing have been completed exclusively by the transmission project team with the intention of realising the full economy potential of the CVT. The resulting driveline returns optimum fuel economy from the diesel engine without the sacrifice of driveability or performance. The complete control package can be conveniently split into two subsystems concerned with driver command and system status processing, leading to the formulation of control decisions, and the subsequent conversion of electronic signals to operating forces. The micro-computer based control unit and its associated electrohydraulic control valves are separately described, in particular the failsafe operation of the total system.
