Document Type and Number:
WIPO Patent Application WO/2019/049682
Kind Code:
A1
Abstract:
This on-vehicle device causes a signal to be transmitted from a plurality of transmission antennae provided to a vehicle so as to be separated from each other, and executes processing in accordance with a response signal from a portable device which has received the signal. The on-vehicle device is provided with: a first transmission control unit which causes the signal to be simultaneously transmitted from at least two transmission antennae among the plurality of transmission antennae; a phase control unit which, if a response signal from a portable device to the signal transmitted from the two transmission antennae is not received, changes the phase relationship of the signal simultaneously transmitted from the two transmission antennae; and a second transmission control unit which causes the signal of which the phase relationship has been changed to be transmitted from the two transmission antennae.
