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 unit, 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.

Field map
01 Unmanned Cars at Airports and Harbors
Unmanned Cars at Airports and Harbors

Autonomous AGV operation in airports and harbors is possible by placing markers in a grid shape.

02 Light Rail Transit
Light Rail Transit

Lower costs can be achieved by switching subway and LRT to buses.

03 High-speed bus transportation system

Fully automatic operation is also easy by introducing from docking and by-passing assist.

04 Driving in high-rise commercial districts
Driving in high-rise commercial districts

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.

05 Valet Parking in Underground Parking
Valet Parking in Underground Parking

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.

06 Driving under snow or in the mist
Driving under snow or in the mist

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.

07 Transport within factory complexes

This facilitates the automatic operation of distribution vehicles on the factory premises.

08 Running in tunnels or under elevated tracks
