Ford’s New Patent: Autonomous Parking Collision Avoidance

Is Ford’s new patent for autonomous parking collision avoidance a game-changer in the ADAS landscape?

Introduction

In a recent development, Ford has unveiled a new patent (US-12617393-B2) that aims to make parked vehicles autonomously move to avoid or mitigate collisions. This technology, first discovered by Road & Track, was filed in 2023 and recently made public. The system, named ‘Moving Object Detection System,’ uses existing sensors on the vehicle to monitor the surroundings and take evasive action if a collision is imminent.

How It Works

The Moving Object Detection System continuously monitors the environment around the vehicle using its onboard sensors. When it detects a potential collision threat, such as another vehicle, shopping cart, or pedestrian, it first issues an audio-visual warning by flashing lights and sounding the horn. If the warning does not deter the object and the collision risk remains high, the vehicle will autonomously move slightly to avoid or reduce the impact. The system also considers static obstacles like other parked vehicles, barriers, and structures to ensure safe movement.

Key Features

• Continuous Monitoring: The system uses existing sensors to monitor the vehicle’s surroundings.
• Audio-Visual Warnings: Initial warnings are issued to alert nearby objects.
• Autonomous Movement: The vehicle can move slightly to avoid or mitigate a collision.
• Static Obstacle Consideration: The system takes into account static obstacles to ensure safe movement.

Technical Feasibility and Challenges

Ford claims that this technology can be implemented without additional hardware, as many of their current models already have the necessary sensors for Level 2 ADAS systems like Blue Cruise. However, the actual deployment faces regulatory hurdles. Most regions do not yet allow vehicles to move autonomously without a driver present, which is a significant barrier to commercialization. Additionally, there are concerns about potential misuse, such as individuals intentionally triggering the system with shopping carts or bicycles.

Regulatory and Ethical Considerations

• Regulatory Hurdles: Current laws in most regions do not permit autonomous movement without a driver.
• Ethical Concerns: Potential for misuse, such as intentional triggering of the system.

Industry Impact and Future Prospects

This patent highlights Ford’s commitment to advancing ADAS technologies. While the technology is still in the patent stage, it demonstrates the company’s forward-thinking approach to vehicle safety. Other automakers, such as Tesla and BMW, are also exploring similar technologies, but Ford’s solution stands out for its use of existing hardware, potentially making it more cost-effective and easier to implement.

Competitive Landscape

• Tesla: Known for its Autopilot system, which includes advanced ADAS features.
• BMW: Developing similar technologies, but with a focus on integrating them into their iDrive system.

Conclusion

Ford’s new patent for autonomous parking collision avoidance is a significant step forward in ADAS technology. While it faces regulatory and ethical challenges, the potential benefits in terms of enhanced safety and reduced damage could make it a valuable addition to the automotive industry. As the technology matures and regulations evolve, we may see more widespread adoption of such systems in the future.
