Title:
TRANSMISSION CONTROL DEVICE, VEHICLE SYSTEM, TRANSMISSION CONTROL METHOD, AND CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/100414
Kind Code:
A1
Abstract:
A transmission control device that drives a plurality of antennas that have different transmission ranges. The transmission control device comprises: a normal transmission control part (341) that makes one normal transmission antenna from among the antennas transmit, on a carrier wave, a normal code that is for starting a portable apparatus; and an inverse transmission control part (342) that, at the same timing as the normal transmission antenna is made to transmit the normal code, makes an inverse transmission antenna from among the plurality of antennas that has a transmission range that does not overlap the transmission range of the normal transmission antenna transmit, on a carrier wave, an inverse code that is generated by inverting at least a portion of the normal code.
