The traffic congestion in modern cities deteriorates urban bus' fuel economy and pollutes the atmosphere seriously, Hydraulic hybrid system becomes one of the efficient ways to improve motor's fuel economy and reduce its pollution under the frequent starts and stops. In order to improve the power performance, a front located parallel hydraulic hybrid (FPHH) configuration is proposed. Through dynamic...
Vehicle energy-saving is important to relieve source shortage and protect environment. This article mainly discusses the control of parallel hydraulic hybrid heavy vehicle (PHHHV), which uses hydraulic components to recycle the brake energy. Through analyzing the two power sources and two brake systems in the PHHHVs, the control rules have been brought out. By logic threshold value control strategy,...
