Optimal operating point determining method for vehicle drive chain, involves finding operating point data in coordinator using characteristics map, and optimizing point in other coordinator by considering vehicle aggregate dynamic behavior

摘要

The method involves determining operating point data in a coordinator (1) under application of stored engine characteristics map. The operating point data determined in the coordinator is optimized in another coordinator (2) under consideration of dynamic behavior of a vehicle aggregate. The map is accessed by using a parameter vector with variable units that comprises variables such as a preset drive moment by a driver of a vehicle, momentary vehicle speed and loading power required for an onboard supply system. An independent claim is also included for a device for determining an optimal operating point for a complete drive chain in a vehicle.
