Hyundai Mobis develops system for driving and parking in narrow spaces


Hyundai Mobis has developed the world’s first urban Advanced Driver Assistance System (ADAS) called the Mobis Parking System (MPS), which would aid drivers in narrow streets, when they are inexperienced.

  • NSA needs just 16 inches of space on either side to drive through a narrow street
  • MPS uses ultrasonic sensors to detect objects
  • RSPA system helps the car parallel park after the driver gets out

The Mobis Parking System integrates Narrow Space Assistance (NSA), Reverse Assistance (RA) and Remote Smart Parking Assistance (RSPA). Researchers are testing related technologies at the Hyundai Mobis Seosan proving ground.

MPS-enabled cars can drive themselves through a narrow street by avoiding obstructions, drive through the revolving gate of an underground parking lot, or drive backwards at a dead end where two cars are facing each other, at the press of a button.

Hyundai Mobis says it developed this technology using its own software logic and mass-produced ultrasonic sensors. This technology is based on the fact that while Radar and LiDAR sensors are useful for recognising objects located far away, or during high-speed driving, ultrasonic sensors are more suitable for narrow streets or underground parking lots. The ultrasonic sensors recognise objects over a short distance, while the software logic and the control system self-drive the car.

Core technologies used

One of the core technologies of this system is NSA. The car needs only 16 inches of extra space on both sides to drive through a narrow street by itself. There is also RA, which records the car’s travel route on a real-time basis and creates the reverse route by itself at the press of a button. The steering wheel and vehicle speed are controlled automatically.

Aside from the Mobis Parking System, various other technologies for safety and convenience have been integrated into the system, further enhancing the competitiveness of the driver assistance solution.

The RSPA system is capable of parallel parking a car or parking at a right angle by finding an empty space after the driver gets out and presses the remote. 3D Surround View Monitor (SVM) provides a better parking experience by having a 360-degree view around the car three-dimensionally. The cars also get Rear-autonomous Emergency Braking (R-AEB).

Hyundai Mobis says it “will pre-emptively suggest global automakers to apply related technologies. The application scope will be expanded to purpose-built vehicles as well as large SUVs, whose popularity is now growing rapidly.”
