Hydraulic hybrid transmissions have demonstrated considerable potential in improving the fuel economy of on-road and off-highway vehicles. The authors have previously proposed a novel hydraulic hybrid transmission architecture termed the Blended Hybrid with benefits in efficiency and performance over existing systems. Recently an optimally controlled simulation study found that a blended hybrid power split transmission consumed 16% less energy than an equivalent series hybrid power split transmission over the US standard Urban Dynamometer Driving Schedule. To further explore this novel architecture the authors constructed a hardware-in-the-loop transmission test rig. In this paper the authors detail the construction, control, and measurements results of the blended hybrid on this test rig.
