On-board vehicle electrical system has 2 voltage levels coupled by coupling device, regulating device that controls longitudinal regulator taking into account future load on second voltage level

摘要

The system has at least one first and second voltage level (30,36), a generator (10), whereby the first and second voltage levels are coupled together via a first coupling device (32) containing a longitudinal regulator, and a first regulating device (34) that controls the longitudinal regulator taking into account the future load on the second voltage level. AN Independent claim is also included for the following: (a) a method of operating an inventive on-board electrical system for a motor vehicle.
