The invention discloses a correcting method for a vehicle door telecontrol system. The correcting method comprises the following steps that a, when a numerical value on a counter is zero, and a second infrared sensor receives an infrared signal earlier than a first infrared sensor, the numerical value on the counter is judged to be abnormal; b, when the numerical value on the counter is judged to be abnormal, a microwave detector detects again, and compares a secondary detection result with an initial detection result; c, when the secondary detection result of the microwave detector is consistent with the initial detection result, the numerical value of the counter is reset; d, when the secondary detection result of the microwave detector is not consistent with the initial detection result, whether the characteristics of the secondary detection result detected by the microwave detector compared with the initial detection result are reduced or not is judged; and e, if the characteristics in the step d are reduced, the numerical value on the counter is reset. When the numerical value on the counter is zero, if the second infrared sensor still receives the infrared signal earlier than the first infrared sensor, it is illustrated that the datum of the counter is wrong and then the counter is reset so that the accuracy of the datum can be ensured.
