|1. (WO2018181053) MARKER SYSTEM|
|Applicants:||AICHI STEEL CORPORATION
Provided is a marker system (1), comprising: a sensor array (21) for detecting magnetic markers installed atop a roadway; a tag reader (34) for acquiring marker position information, which represents the installation positions of the magnetic markers; an IMU (22) for estimating the relative vehicle position by inertial navigation; and a control unit (32) for executing a computation process to identify the vehicle position. The marker system (1) enables a consistent identification, independent of the surrounding environment, of the self-position by identifying the vehicle position on the basis of the installation positions of the detected magnetic markers and by identifying the vehicle position following the passage of the vehicle over the magnetic markers on the basis of the relative vehicle position estimated by the IMU (22).
