An on-board device, a vehicle communication system, and a direction-of-arrival estimation method are provided. An on-board device transmits signals from a plurality of transmission antennas that are provided for a vehicle at positions that are separate from each other, and performs processing corresponding to a response signal from a portable device that has received the signals. The on-board device includes: a reception unit that receives the response signal via a plurality of reception antennas that are provided for the vehicle at positions that are separate from each other; and an estimation unit that estimates a direction of arrival of the response signal based on a phase difference of the response signal received via the plurality of reception antennas.
