BUERGER JOHANNES / R SCHMIDT

The invention relates to a method for operating an hybrid electric motor vehicle, having an electric drive unit (2) and a combustion-engine-powered drive unit (3), on a driving route, said method comprising the following steps: dividing the driving route into route segments; rule-based classifying of the route segments as first route segments to be traveled in an electrically powered manner or second route segments to be traveled in a hybrid-powered manner; predicting an electrical energy to be required for the first route segments and to be provided by an electrical energy accumulator (13) of the electrical drive unit (2); determining a remaining energy for the second route segments according to the electrical energy required for the first route segments; optimisation-based and rule-based determining of a load point distribution between the electrical drive unit (2) and the combustion-engine-powered drive unit (3) in the second route segments, minimising a fuel consumption of a combustion engine (4) of the combustion-engine-powered drive unit (3) according to the remaining energy of the electrical energy accumulator (13) and a limitation of start-stop processes of the combustion engine (4). The invention also relates to a control device and a hybrid electric motor vehicle.

本发明涉及一种用于在行驶路程上运行混合电动车辆的方法，该混合电动车辆具有电驱动单元(2)和内燃机式驱动单元(3)，该方法具有以下步骤：‑将行驶路程划分成多个路程部段；‑将这些路程部段基于规则分类为要电动行驶的第一路程部段或能混合行驶的第二路程部段；‑预测对于第一路程部段需要的、要由电驱动单元(2)的电能存储器(13)提供的电能；‑根据对于第一路程部段所需的电能确定用于第二路程部段的剩余能量；‑在内燃机式驱动单元(3)的内燃机(4)的燃料消耗最小化情况下，根据电能存储器(13)的剩余能量以及根据对内燃机(4)的起停过程的限制，基于优化地并且基于规则地确定在第二路程部段中在电驱动单元(2)与内燃机式驱动单元(3)之间的负荷点分配。本发明还涉及一种控制装置以及一种混合电动车辆。
