摘　　要：为了解决汽车电动车窗夹伤乘员的安全问题,提出一种基于电流差的电动车窗防夹算法。算法首先通过滑动平均滤波滤除电流部分噪声,然后利用最小二乘法计算电流斜率和电流均值辅助分析车窗是否遇到障碍物和处理电流差,再将电流差和阈值比较做出是否防夹的判断。实车防夹力测试和恶路测试结果表明,基于电流差的电动车窗防夹算法实车测试防夹力为(80±5)N,误防夹率小于1%,满足法规要求,验证了该算法的可行性。In order to solve the safety problem of vehicle electric window clipping,an electric window anti-clipping algorithm based on current difference was proposed.The algorithm firstly filters out the noise of the current part by sliding average filtering,and then calculates the slope and mean of the current to analyze whether the window encounters obstacles and deal with the current difference.Then it compares the current difference with the threshold to judge whether the anti-clip function is triggered.The results of real vehicle anti-clamping force test and bad road test show that the real vehicle anti-clamping force of the electric window anti-clamping algorithm based on current difference is 80N±5N,and the false anti-clamping rate is less than 1%,which verifies the feasibility of the algorithm.
