用于运行液压混合动力车辆的方法
摘要：
本发明涉及一种用于运行液压混合动力车辆的方法，该液压混合动力车辆包括作为一级驱动装置的内燃机(4)和作为二级驱动装置的至少两个静液压装置(21‑24)，所述至少两个静液压装置中的至少一个在能量回收运行中将制动能量转化为液压能量，该液压能量储存于一个液压蓄压器(40)中。为了改善液压混合动力车辆的运行性能，下坡行驶时，与液压混合动力车辆的倾斜度相关地预给定被用于制动该液压混合动力车辆的内燃机(4)牵引功率。
摘要（英）：

The invention relates to a method for operating a hydraulic hybrid vehicle which comprises an internal combustion engine (4) as the primary drive and at least two hydrostatic units (21-24) as the secondary drives, at least one of said hydrostatic units converting braking energy to hydraulic energy in a regenerative mode, which hydraulic energy is stored in a hydraulic pressure accumulator (40). In order to improve the operating behavior of the hydraulic hybrid vehicle, a drag power of the internal combustion engine (4) used during downhill travel to brake the hydraulic hybrid vehicle is specified depending on a tilt of the hydraulic hybrid vehicle.
