Abstract
A vehicle system includes a sensor unit including magnetic sensors for detecting a magnetic marker and non-contact displacement sensors which measure a displacement relative to a road surface where the magnetic marker is laid, a processing circuit which performs detection process for detecting the magnetic marker by processing a magnetic measurement value by the plurality of magnetic sensors, and a switching circuit which switches the detection process in accordance with displacement measurement values by the non-contact displacement sensors. By switching the detection process in accordance with the displacement measurement values by the non-contact displacement sensors, the magnetic marker can be detected with high reliability.
