Title:
METHOD FOR OPERATING A HYBRID VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/054880
Kind Code:
A3
Abstract:
The invention relates to a method for operating a hybrid vehicle (1), which is operated with an internal combustion engine, an electric machine (7) and a transmission, the transmission being connected to said internal combustion engine via an input shaft, a first electrical network, a second electrical network as an on-board network, which is operated on a lower voltage level than the first electrical network, the first electrical network being operated at a higher voltage level than the second electrical network. The following elements are operated while being coupled to the first electrical network: the electrical machine, an electrical energy storage device, and an energy converter which transfers electrical power at least from the first electrical network to the second electrical network, an alternator being dispensed with in the second electrical network. The invention is characterized in that the first electrical network is designed as part of a transmission system which is actuated together with the components coupled thereto by means of a transmission control device, wherein power is generated by the electrical machine, and wherein the energy supply of the second electrical network has a higher priority during power distribution than a motor support of the drive of the input shaft by the electrical machine.
