Parameters Matching and Control Method Research of Hydraulic Hybrid Vehicle with Secondary Regulation Technology
Along with the shortage of energy and the increasingly serious pollution of environment in cities, automobile industries all over the world are exploring and developing energy saving and clean automobile. Hydraulic hybrid vehicle can regenerate the kinetic energy of vehicle in short time, has better potential in medium-size and large-size passenger car than its electric counterparts. But hydrostatic transmission system and energy storage components have the unique characteristics that are very different from their electric counterparts, thus requiring special power matching design and control strategy to coordinate all the powertrain components, so that they can work together in an optimal manner. A genetic algorithm is applied for parametric optimization of the key components by consideration of requirements of driving cycles and technology aspects. The regenerative braking strategy and energy control strategy based on poweitrain components optimization is proposed to control the regeneration and distribution of the braking energy. Simulation results demonstrate that the optimization watching strategy and energy control strategy takes advantage of high power density characteristics of hydraulic components, and minimizes disadvantages of low energy density, which is quite effective in improving the performance, fuel economy and energy regenerative rate of hydraulic hybrid vehicle.
