Anti-pinch control method and system for electric vehicle window
The invention relates to the technical field of automobiles, and provides an anti-pinch control method for an electric vehicle window, which includes the following steps: five steps S1 to S5. The invention also provides an anti-pinch control system for the electric vehicle window, and the system includes an MCU controller, a temperature measurement module and a current detection and processing module. The method and the system are characterized in that: a correspondence table of temperature and a current threshold coefficient is established, initialization setting for self-learning of the electric vehicle window is simplified, and the complexity of software design of the controller is also reduced; based on ripple current detection technology, adoption of a special motor or installation ofa Hall sensor is not required, and the cost of an anti-pinch system is reduced; in the early stage of the software design of the controller, a direct current motor current model is established through test data, including the effect of a vehicle window lifting mechanism and friction between glass and window frames on a current threshold, and the accuracy of the control system is improved; and theeffect of temperature on a threshold is considered, and reliability and accuracy of an anti-pinch function are ensured.
本发明涉及汽车技术领域，提供了一种电动车窗防夹控制方法，包括如下步骤：S1～S5五个步骤。本发明还提供一种电动车窗防夹控制系统，包括MCU控制器、温度测量模块以及电流检测处理模块。本发明建立温度与电流阈值系数的对应关系表，简化了对电动车窗自学习的初始化设置，也降低了控制器软件设计的复杂度；基于纹波电流检测技术，不需要采用特殊电机或安装霍尔传感器，降低防夹系统的成本；通过在控制器软件设计前期，通过试验数据，建立直流电机电流模型，包含车窗升降机构以及玻璃与窗框之间的摩擦对电流阈值的影响，提高控制系统的准确性；考虑了温度对阈值的影响，保证防夹功能可靠性和准确性。
