The present invention relates to a touch door opening/closing system for a vehicle with a sub-channel touch sensor. A sub-channel touch sensor is arranged adjacent to a main channel touch sensor to perform normal opening/closing operation of doors for a vehicle; a change value between each main channel touch sensor and each sub-channel touch sensor is compared and analyzed by a sensor signal determination unit; and a capacitance variation of the touch sensors is determined to be due to various foreign substances such as liquid foreign substances, including rainwater, ice, soapy water used for washing a vehicle, an electrolyte solution like calcium chloride in winter or the like, and the like, or solid foreign substances including yellow dust, dust, fallen leaves, waste paper, and the like, or a human body, thereby preventing error and malfunction of the touch door opening/closing system. |
