Title:
PORTABLE DEVICE, VEHICULAR ON-BOARD DEVICE, AND WIRELESS COMMUNICATION SYSTEM FOR VEHICLES
Document Type and Number:
WIPO Patent Application WO/2018/066244
Kind Code:
A1
Abstract:
A reception unit of a vehicular on-board device receives an unlock request signal that includes a rolling code from a portable device. The unlock request signal, in the portable device, to be received by the reception unit also includes continuous request information in addition to the rolling code when the next request is received within a fixed time from receiving the request to unlock the door. A storage unit stores the time when the reception unit received the unlock request signal. When continuous request information is included in the unlock request signal, a determination unit determines not to unlock a door lock if the difference between the time when the unlock request signal was received that is stored by the storage unit and the time when the unlock request signal immediately before this unlock request signal was received is greater than the interval corresponding to the fixed time.
