Abstract
The present disclosure relates to a method and an apparatus for controlling a lubricant flow rate in a wet clutch. The method comprising: determining a clutch state as an open state, a closed state or a slipping state; determining a clutch temperature and a sump lubricant temperature; based at least on the clutch state, the clutch temperature and the sump lubricant temperature, selecting one out of a plurality of maps, wherein each map maps one or more operating parameters of the clutch on a target lubricant flow rate; determining a target lubricant flow rate based on the one or more operating parameters according to the selected map; and controlling a lubricant flow control device based on the determined target lubricant flow rate.
