摘要
针对车辆电子液压制动系统存在的能量消耗问题,建立了电子液压制动系统的能耗数学模型,在此模型的基础上分析系统参数和零部件结构参数对电子液压制动系统耗能特性的影响.结果表明减小系统最高工作压力和制动轮缸活塞直径有利于降低电子液压制动系统的耗电量,而系统最低工作压力和蓄能器有效排量的改变对电子液压制动系统的耗电量影响不大.增加蓄能器充气压力、减小蓄能器有效排量以及制动轮缸活塞直径有利于缩小蓄能器体积.
To solve the energy consumption problem existing in the electronic hydraulic braking system,a mathematical model was established for energy consumption analysis,and the effect of system parameters and structure parameters on energy consumption characteristics of electronic hydraulic braking system were analyzed based on this mathematical model.Analysis results show that,reducing the maximum system working pressure and diameter of brake wheel cylinder piston is beneficial to decrease the power consumption of electronic hydraulic brake system,but the change of the minimum system working pressure and the effective discharge of the accumulator have a little influence on it.Increasing the charging pressure of accumulator or reducing the effective discharge of accumulator and the diameter of brake wheel cylinder piston will make the accumulator smaller.
