Embodiment Construction
[0024] figure 1A schematic diagram of a control device 100 according to an embodiment of the present disclosure is shown. The control device 100 comprises a feedback component 101 which provides current system information (eg current rotational speed and torque of the internal combustion engine and desired rotational speed of the propulsion electric machine). The control device 100 also includes an energy management component 102 that determines desired power based on system feedback from the feedback component 101 . Information about the desired power and system feedback is passed to the charging power component 103, which determines the requested charging power for the power source including the integrated starter engine and internal combustion engine. The control device 100 also includes an operating point component 104 that determines a desired operating point of the internal combustion engine based on system feedback and desired power. The information of the desired ope...

A system for controlling an operating point of a power source for a propulsive e-machine in a hybrid electric vehicle, comprising: a power train comprising a power source and at least one propulsive e-machine, wherein the power source comprises an integrated starter generator and an internal combustion engine; at least one desired operating point for the power source comprising at least one characteristic parameter; an operating point component configured to query the at least one desired operating point and to distribute the control of the at least one desired operating point to a control of the internal combustion engine or to a control of the integrated starter generator control, wherein in case the at least one characteristic parameter of the at least one desired operating point is in a predetermined limit, the operating point component distributes the control of the at least one desired operating point to the control of the internal combustion engine, and in case the at least one characteristic parameter of the at least one desired operating point is beyond the predetermined limit, the operating point component distributes the control of the at least one desired operating point to the control of the integrated starter generator.
Description
technical field [0001] The present disclosure relates to a system for controlling an operating point, a control device, an electric vehicle comprising such a control device and the use of such a control device in a hybrid electric vehicle. Background technique [0002] In the prior art, hybrid electric vehicles of various designs are known. For example, series hybrid electric vehicles are known which include an electric powertrain with a power source and a propulsion electric machine. Power sources include an internal combustion engine (ICE) and an integrated starter generator (ISG), where the propulsion motor provides all the power needed to propel the vehicle. The efficiency of the power source depends on the selected operating point, where some operating points provide increased ICE efficiency and improved NVH characteristics of the ICE. However, deviations from these beneficial operating points result in reduced efficiency. [0003] In view of this, it has been found ...
