Abstract
In a vehicle door control system, a portable unit stores registration of an instruction of automatic door-opening to a vehicle unit, when predetermined registration processing is made on the portable unit. In response to a request signal from the vehicle unit, the portable unit transmits a response signal including an ID code and the instruction of the registered automatic door-opening operation. The vehicle unit unlocks a vehicle door without any manual door-unlocking operation by a user and automatically opens the vehicle door, when the response signal includes the instruction and the ID code matches a predetermined ID code.
