基于采用一体式制动主缸总成的电动汽车电液复合制动系统的结构和工作原理，在AMESim/Matlab联合仿真平台上搭建液压制动系统模型。通过对液压制动力调节特性的理论分析提出数表插值算法，并通过仿真试验分析轮缸制动间隙对压力调节的影响，运用分段控制的方式，用阶梯法对数表插值算法进行改进，在不大于3个电磁阀开关周期的调节时间中将压力调节精度控制在0.5 MPa内，实现了精细快速的调节目标。

Based on the structure and operating principle of a new electro-hydraulic brake system with integrated master cylinder in electric vehicle, a model of hydraulic braking system is built with the co-simulation platform of AMESim and MATLAB. With the theoretical analysis for the brake pressure regulating characteristics, an interpolating algorithm using numerical table is proposed. The impact on pressure regulation exerted by braking clearance of wheel cylinder is analyzed through simulation. Then by the way of piecewise pressure estimation, the algorithm is improved with staircase method. As a result, the braking pressure precision is controlled within 0.5MPa in no longer than three switching periods of solenoid valve, the regulating objective is thus achieved.
