BUS NAVIGATION SYSTEM AND METHOD OF BUS NAVIGATION

摘要

PROBLEM TO BE SOLVED: To allow a guide to a specific location such as a bus depot and the like to be stably and correctly implemented on the basis of a GPS signal even when there is a change in the number of capturable GPS satellites.;SOLUTION: A bus navigation system 10 of a bus vehicle BUS using a GPS signal GS comprises: a first register 16A that retains a stabilization reception coordinate SRP in which the number of the GPS satellites determined from the GPS signal GS is more than a predetermined number M; a microcontroller 14 that extracts a bus depot BS_n from route information DI, detects a vehicle speed pulse 22 of the bus vehicle BUS, further computes a travelling distance LD of the bus vehicle BUS from a stable coordinate SP using the vehicle speed pulse 22, and specifies a bus coordinate PrS from the travelling distance LD and the stable coordinate SP; and a sound source part 26 that, when the bus coordinate PrS enters within a guidance start area AR, starts a guidance of the bus depot BS_n with respect to passengers of the bus vehicle BUS.;COPYRIGHT: (C)2015,JPO&INPIT
