About GMPS Technology
Autonomous Driving
High-precision, highly reliable autonomous driving
achieved by GMPS (Magnetic Positioning System)
Aichi Steel's GMPS (Global Magnetic Positioning System) is a magnetic vehicle position detection system that detects weak magnetic signals emitted by magnetic markers installed on the ground with an ultra-sensitive magnetic sensor, "MI Sensor", mounted on the sensor module, estimates the position of the vehicle with high accuracy, and supports advanced vehicle control such as automated driving.
In tunnels and underground where GPS does not reach, and in situations such as snow accumulation, fog, and backlight where optical devices struggle, the position of the car is identified at +/-5 mm or less to support safe autonomous driving.
GMPS Technology Principle of Operation
An autonomous driving support system that estimates the position of a car with high accuracy from the weak magnetic force of a magnetic marker laid along a lane using the MI sensor module mounted on the bottom of the car.
The position of the car (X-Y coordinates) is accurately identified by the signals from the magnetic markers with RF-ID on the road surface.
It tracks at speeds of up to 200km/hour.
Applications Field of activity
GMPS can be used in a variety of environments with a single system.
Autonomous AGV operation in airports and harbors is possible by placing markers in a grid shape.
Lower costs can be achieved by switching subway and LRT to buses.
Fully automatic operation is also easy by introducing from docking and by-passing assist.
Even in a state where GPS satellites cannot be supplemented or in built-up streets where GPS multipathing occurs, accurate automotive positions can be identified from magnetic markers.
Valet parking becomes easier even in indoor parking lots where GPS signals do not reach. The vehicle moves tracing the specified ID number of the magnetic markers.
Magnetic markers can reliably locate your car even in environments with snow or fallen leaves that make it impossible to read white lines. You can also identify your car's position in mist where Lidar doesn't work precisely.
This facilitates the automatic operation of distribution vehicles on the factory premises.
Accurate automotive position estimation is possible even in tunnels or under elevated tracks where GPS signals cannot be obtained.
