AI Technical Summary
Technical Problem
Hidden door handles are prone to freezing in cold, rainy, or snowy weather, making them unable to pop out and affecting vehicle use.
Method used
Design an anti-icing algorithm that uses the vehicle's built-in temperature sensor, rain sensor, and VCU to control the pop-out action of the handlebars. The algorithm collects resistance values through a resistance sensor and adjusts the pop-out time based on the derivative value, ambient temperature, and weather conditions to prevent freezing.
Benefits of technology
It effectively prevents the hidden door handles from freezing in thin ice, ensuring that the doors can be used normally, avoiding user complaints, and without damaging the paint.

Abstract
一种弹出式隐藏车门把手的防结冰算法涉及隐藏车门技术领域，避免车门被冻住使驾驶人员无法正常使用车辆。该算法包括如下步骤：车辆内置温度传感器采集车辆处于的环境温度；当环境温度小于等于0o时，车辆内置雨量传感器采集车辆处于的天气情况；当天气情况为雨雪天气时，整车VCU采集车辆处于的状态；当车辆处于熄火状态时，整车VCU执行把手弹出动作；当把手弹出失败时，手把传感器采集把手的阻力值，在标定时长后整车VCU再次执行把手弹出动作；同时对再次弹出阻力进行采集，与上一次阻力值进行求导，根据求导值和采集的环境温度与天气情况调整把手弹出时间，实现一种弹出式隐藏车门把手的防结冰算法。
