Car window anti-pinch processing method and system for recognizing bumpy road surface by using acceleration
The invention discloses a car window anti-pinch processing method and system for recognizing a bumpy road surface through acceleration. The system comprises an acquisition module, a filtering module, a judgment module and an execution module. The method comprises the following steps: acquiring acceleration, and fitting into an acceleration-time curve; carrying out filtering processing on the collected acceleration-time curve; judging whether the vehicle enters a bumpy road surface or not according to the filtered acceleration-time curve period; and after the vehicle is identified to enter the bumpy road surface, the anti-pinch inhibition coefficient is increased within the bumpy time, so that the anti-pinch force is increased. The acceleration characteristic of the vehicle running on the bumpy road surface is recognized through the safety air bag controller or other equipment with an acceleration sensor, the acceleration-time curve is collected, it is judged that the vehicle enters the bumpy road surface according to the periodic change of the acceleration-time curve, the state is kept for a certain time, the anti-pinch judgment condition is optimized, and the anti-pinch effect is improved. And the false anti-pinch probability is reduced to the greatest extent under the condition of ensuring that the anti-pinch function is effective in the vehicle driving process.
本发明公开了一种使用加速度识别颠簸路面的车窗防夹处理方法及系统，所述系统包括采集模块、滤波模块、判断模块和执行模块；所述方法包括采集加速度，拟合成加速度‑时间曲线；对采集的加速度‑时间曲线进行滤波处理；根据滤波处理后的加速度‑时间曲线周期判断车辆进入颠簸路面；识别到车辆进入颠簸路面后在颠簸时间内增大防夹抑制系数，从而增大防夹力。本发明通过安全气囊控制器或其他具备加速度传感器的设备识别车辆行驶在颠簸路面时的加速度特性并进行加速度‑时间曲线采集，通过加速度‑时间曲线周期变化判断车辆进入颠簸路面，并保持此状态一定时间，优化防夹判断条件，在确保车辆行驶过程中防夹功能有效的情况下最大程度降低误防夹概率。
