The invention discloses a capacitive controller for an external window of a vehicle. The capacitive controller comprises a first sensing electrode, a second sensing electrode and a third sensing electrode of a capacitor chip, the first induction electrode is used for forming a user touch area; the second induction electrode forms a user touch area for the first induction electrode to form a running water induction area; the third induction electrode forms a user touch area for the first induction electrode to form an interference identification area; the capacitor chip is connected with the first induction electrode, the second induction electrode and the third induction electrode, collects capacitance values of the three induction electrodes respectively, and corrects the collected capacitance value of the first induction electrode based on the collected capacitance value of the second induction electrode and/or the third induction electrode so as to judge the touched state of the user touch area formed by the first induction electrode. Compared with a traditional capacitive controller, the capacitive controller has the advantages of high control precision, high reliability, waterproof capability and high interference resistance.

    本发明公开了一种车外车窗电容式控制器,包括电容芯片第一感应极,第二感应极,第三感应极;第一感应极用于形成用户触摸区;第二感应极针对第一感应极形成用户触摸区域形成流水感应区;第三感应极针对第一感应极形成用户触摸区域形成干扰识别区;电容芯片连接第一感应极,第二感应极,第三感应极,分别采集三个感应极的电容值,基于采集到的第二感应极和/或第三感应极的电容值来对采集到的第一感应极电容值进行修正,以判断第一感应极形成的用户触摸区被触摸的状态。本方案相对于传统的电容式控制器,控制精度高,可靠性强,具有防水能力,抗扰性强。
