ON-VEHICLE MAGNETIC SENSOR, VEHICLE POSITION DETECTION DEVICE AND AUTOMATIC OPERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To appropriately correct the detection result of a magnetic field strength change quantity by a first detection means by providing the first detection means detecting the magnetic field strength change quantity of a magnetic marker and making its own vehicle position detection result by a second detection means to be a base. SOLUTION: The on-vehicle magnetic sensor is provided with a map recording device (CD and DVD) 111, a GPS receiver 113, a vehicle speed sensor/yaw rate sensor 115 and the automatic position detection part (navigation device) 109 of a second detection means, which detects its own position based on information. A magnetic disturbance position passage judgment part 107 judging whether its own vehicle passes through a magnetic disturbance point from the detection result of its own vehicle position by the navigation device 109 and magnetic disturbance point information from the map recording device 111 is installed. The magnetic field strength change quantity detection part 101 of the first detection means, which detects the change quantity of the magnetic field strength of the magnetic marker, and a signal processing pat 103 which appropriately corrects the detection result of the magnetic field strength change quantity detection part 101 is accordance with the judged result of the magnetic disturbance position passage judgment part 107 are installed.
