PROBLEM TO BE SOLVED: To provide a control system that prevents a portable device from being locked in a vehicle due to the leakage of electromagnetic waves in the vehicle when door locking/unlocking is performed by communication between the portable device and the vehicle.SOLUTION: A specified period from when a vehicle door is closed, is defined as an ineffective period of NFC function, and door locking is not performed even when a smartphone A is detected by the vehicle at a time t4 during the ineffective period. At a time t5 after the ineffective period passes, when a smartphone B is detected, door locking is performed. Thus, even when a detection at the time t4 is based on the smartphone A in the vehicle which has moved into the reaching range of electromagnetic waves internally-leaked from an NFC reader from outside the reaching range due to vibration of the vehicle caused by door closing, this prevents the smartphone from being locked in the vehicle without incorrectly identifying the detection as an operation from the smartphone outside the vehicle. |
