Title:
DEVICE AND METHOD FOR FILTERING RECEIVED MESSAGE OF DEDICATED SHORT RANGE COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP2018098782
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To cope with a problem of a DSRC(Dedicated Short Range Communication) radio channel for receiving a message at a frequency exceeding the capability of the DSRC radio channel and/or a processing speed of a CPU of a DSRC system.SOLUTION: A DSRC system comprises a processing module for determining a received signal strength (RSS) of a received message, and for determining whether or not the RSS of the received message is larger than an RSS threshold, and for processing the received message in accordance with the RSS of the received message larger than the RSS threshold. The processing module determines at least one of a CPU use rate and a message received frequency (MRF) of the DSRC system. Then, an RF filter control module 48 adjusts the RSS threshold in accordance with at least one of the CPU use rate larger than a CPU threshold, the MRF larger than an MRF maximum threshold and the MRF smaller than an MRF minimum threshold.SELECTED DRAWING: Figure 3
