Power window anti-pinch method and system
The invention discloses a power window anti-pinch method and system, and relates to the technical field of power window anti-pinch, and the method comprises the steps: starting a motor to collect data information in real time, and carrying out the data preprocessing; calculating the travel length of the power window, and judging whether the window is in an anti-pinch area; fitting to obtain the latest current slope when the motor runs by using a least square method fitting curve principle; judging the slope size, recording and controlling the current difference; and further judging whether to trigger the anti-pinch mechanism of the electric vehicle according to the current difference. The threshold value is automatically adjusted according to the severity degree of bumping of the vehicle, normal work of the anti-pinch mechanism under different road conditions is ensured, and the problem that in the prior art, the anti-pinch mechanism is mistakenly triggered due to bumping is solved. The method and the system are easy to implement, do not need complex equipment and high cost, can be widely applied to various power window systems, improve the reliability of the power window, and reduce the risk of damage to the vehicle window caused by false triggering of an anti-pinch mechanism.
本发明公开了一种电动车窗防夹方法及系统，涉及电动车窗防夹技术领域，包括：启动电机实时收集数据信息，进行数据预处理；计算电动车窗行程长度，判断车窗是否在防夹区域；利用最小二乘法拟合曲线原理，拟合得到电机运行时最新的电流斜率；判断斜率大小记录和控制电流差；进一步根据电流差大小，判断是否触发电动车防夹机制。本发明通过实车辆颠簸的严重程度自动调整阈值的大小，确保防夹机制在不同路况下的正常工作，解决了现有技术中因颠簸导致防夹机制误触发的问题。这种方法和系统易于实施，不需要复杂的设备和高昂的成本，可广泛应用于各种电动车窗系统中，提高电动车窗的可靠性，减少因误触发防夹机制而导致的车窗损坏的风险。
