Title:
VEHICLE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/066799
Kind Code:
A1
Abstract:
A vehicle control device (10; 10a) is provided with a first processing unit (111: 130) that performs first processing including a determining process for determining whether a reception signal received through an antenna (21) mounted on a vehicle (100) and then encoded is a normal wireless signal which is a wireless signal transmitted from a portable machine (200). The reception signal is encoded by an encoding system in which 0 is represented by two continuous short bits and 1 is represented by one long bit. The determination process includes a first determination sub-process for determining that the reception signal is the normal wireless signal when the number of the short bits held between two adjacent long bits in the reception signal is even-numbered, and determining that the reception signal is not the normal wireless signal when said number of short bits is odd-numbered.
