The invention is suitable for the technical field of intelligent automobiles, and provides an automobile electronic mechanical brake braking force cooperative control method which comprises the following steps that a central braking domain controller recognizes the control intention of a driver on an automobile, the current motion state of the automobile and the road environment state through feedback information of all sensors; the central braking domain controller calculates the braking force control requirement of each wheel; the central braking domain controller sends a braking request command to the intelligent node controller, the braking force of wheels is adjusted, and increasing, maintaining and releasing of the braking force and parking are achieved; and the intelligent node controller responds to the braking force request, drives the electronic mechanical brake assembly to work, implements a vehicle braking or parking request, and feeds back the working state of the controlled wheel brake in real time. According to the method, a novel braking force cooperation method for electronic mechanical braking is provided, a system architecture capable of being implemented by an automobile electronic mechanical brake is established, the system failure risk controllability is achieved, and the system safety redundancy is high.
本发明适用于智能汽车技术领域,提供了一种汽车电子机械制动器制动力协同控制方法,包括以下步骤:中央制动域控制器通过各传感器反馈信息识别驾驶员对车辆的操控意图、当前车辆的运动状态和道路环境状态;中央制动域控制器计算各车轮的制动力控制需求;中央制动域控制器向智能节点控制器发出制动请求命令,调节车轮制动力大小,实现制动力增加、保持、释放及驻车;智能节点控制器响应制动力请求,驱动电子机械制动器总成工作,实施车辆制动或驻车请求,并实时反馈所控制车轮制动器的工作状态。该方法通过提供一种新型的电子机械制动的制动力协同方法,建立了汽车电子机械制动器可实施的系统架构,具备系统失效风险可控性,系统安全冗余性强。
