The invention relates to a pressure control method and system for an automobile brake-by-wire system and relates to the technical field of brake-by-wire systems, and the method comprises the steps that temperature data, humidity data and pollution degree data of hydraulic oil are collected in real time and recorded as hydraulic oil characteristic data; pressure sensors are arranged at an outlet of a hydraulic source and first to fourth brake wheel cylinders to obtain real-time pressure data in the braking process; the control assembly receives actual opening data collected by the pedal travel sensor and determines target hydraulic pressure; inputting the temperature data, the humidity data and the pollution degree data which are acquired in real time into a pre-constructed relation model; comparing the collected real-time pressure data with the target hydraulic pressure to obtain an actual pressure difference value; a pressure compensation command is generated in the control component based on the pressure deviation and the actual pressure difference.

    本申请涉及一种用于汽车线控制动系统压力控制方法及系统,涉及线控制动系统的技术领域,其方法包括:实时采集液压油的温度数据、湿度数据和污染程度数据,记为液压油特性数据;在液压源出口、第一至第四制动轮缸设置压力传感器,获取制动过程中的实时压力数据;控制组件接收踏板行程传感器采集的实际开度数据并确定目标液压压力;将实时采集到的温度数据、湿度数据、污染程度数据输入预先构建的关系模型中;将采集的实时压力数据与目标液压压力进行对比得到实际压力差值;基于压力偏差和实际压力差值,在控制组件中生成压力补偿指令。
