Method for representing sum wheel moment by moment sources of power train structure of hybrid motor vehicle, involves computing sum wheel moment, making negative sum wheel moment to take place and requiring only brake moment of assembly

摘要

The method involves computing a sum wheel moment from a target acceleration of a driver assistance system by a drive-dynamic model sum wheel moment for propulsion and/or for delay. A negative sum wheel moment is made to take place by an overlap of an engine drag moment (M-M) of an internal-combustion engine (4), a brake moment (M-EM) of an electric machine (8) and a brake moment (M-B) of a brake assembly (6). The brake moment of the brake assembly is only required, when the brake moment of the electrical machine is not sufficient for representation of sum wheel moment. An independent claim is also included for a power train structure comprising an internal-combustion engine.
