<p><P>PROBLEM TO BE SOLVED: To provide a control system or storage device having a noise removal function capable of starting noise removal more quickly than before, in a radio communication system for a vehicle. <P>SOLUTION: A control system 1 acquires position information from a navigation device 4 when a vehicle 2 stops a drive part; checks whether or not a noise removal filter stored in the past in a memory 72 in association with the vehicle position exists in the memory 72; and retrieves the filter and uses the filter in a RF reception part 7 when the filter exists, or calculates a noise removal filter in a filter calculation part 71 and stores the calculated filter in association with the current vehicle position in the memory 72 when the filter does not exist. Thereby, storing a noise removal filter, which is calculated when a vehicle is stopped at a location for the first time, along with its position information makes it possible to quickly remove noise by omitting time for filter calculation from the second time on in the case of coming to the location multiple times. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
