基于再生能量的车辆电液动力制动系统设计理论与方法

There are quite some advantages of electro-hydraulic brake on present-day construction vehicles for the purposes of energy conservation, environment friendliness and safe and efficient operation. The power adjusting system of regenerative energy from hydraulic hybrid power can offer an effective solution, which is essential in the development of this technology, to the power supply problems of restricting power brake and other active control technology. This is due to the fact that this system has increased the complexity of the energy transmission among the sub-systems within the vehicle. This new dynamic designing theory and method for electro-hydraulic brake system based on regenerative energy has been put forward for the design and adjustable control of electro-hydraulic power brake system in the condition of multi-system coupling or difficult vehicle operation. With theoretical analysis and experiment verification, the power adjustment and control mechanism between the active systems of vehicle and storage system of regenerative energy has been made a detailed study of, and as a result, the related design rules have been worked out. The multi-system power adjustment and control principle and law are analyzed and grasped for the stability of whole vehicle braking efficiency, effective recollection and allocation of energy. The integrated design and collaborative optimization of active systems are studied. Energy-saving methods and strategies are proposed between regenerative brake, power adjustment and active systems to achieve the result of highly efficient coupling between all the systems. This project is very significant in both theory and practice for the study of multi-system application and control of regenerated energy, and for the research and manufacture of energy-saving electro-hydraulic power brake system.
