The invention discloses a vehicle side sliding door induction starting device. The vehicle side sliding door induction starting device at least comprises a detector and a control main unit. The detector is arranged in a side-sliding-door type vehicle and can detect the outside of the vehicle. Then, the detector transmits the detection result to the control engine. Default parameters are implantedinto the control engine, and then signals are output to a vehicle body computer after the signals of the detector are received to be compared and determined to meet the conditions, so that the vehiclebody computer outputs driving signals to all vehicle parts at the rear end of an original vehicle design, and a vehicle side sliding door can make automatic starting induction actions.
