Dynamic Programming-based Design of Shift Scheduling Map Taking into Account Clutch Energy Losses During Shift Transients
SAE Paper #2016-01-1116, 2016 SAE World Congress, Detroit, MI2016The paper deals with the design of shift scheduling maps based on
dynamic programing (DP) optimization algorithm. The recorded data
related to a delivery vehicle fleet are used, along with a model of
delivery truck equipped with a 12-gear automated manual
transmission, for an analysis and reconstruction of the truckimplemented shift scheduling patterns. The same map reconstruction
procedure has been applied to a set of DP optimization-based
operating points. The cost function of DP optimization is extended by
realistic clutch energy losses dissipated during shift transients, in
order to implicitly introduce hysteresis in the shift scheduling maps
for improved drivability. The different reconstructed shift scheduling
maps are incorporated within the truck model and validated by
computer simulations for different driving cycles. computer simulations; manual transmissions; simulators
