Off-road autonomous driving has always posed challenges due to the presence of extraneous substances such as dust, mud, snow, and rain. However, a groundbreaking development in Korea has brought forth innovative technologies for recognizing and removing these substances in real-time during off-road driving. Led by Senior Researcher Han-Min Lee, a research team at the Korea Institute of Machinery and Materials (KIMM) has introduced off-road environment recognition technologies that are set to revolutionize the industrial and military sectors.
The newly developed technologies encompass sensor protection and cleaning, sensor signal correction, and drivable area recognition. The “sensor protection and cleaning module” is designed to combat muddy water or mud splashing onto sensors by spraying detergents and wiping them away in real-time through a wiper. This ensures the effective removal of contaminants, enhancing the overall functionality of the sensors. Additionally, the “sensor signal correction” technology targets small-sized extraneous substances like dust, snow, and rain to maintain stable off-road driving conditions, especially in adverse weather conditions. The “drivable area estimation technology” plays a crucial role in detecting obstacles such as steep slopes, potholes, and bumpy roads, providing alternative routes to avoid collisions.
The KIMM has also developed “driving control technology” for real-time vehicle control by selecting necessary functions from the array of technologies available. This not only enhances efficiency but also ensures optimal performance based on specific driving conditions. Previously, the lack of suitable sensor protection and real-time drivable area estimation technologies hindered off-road autonomous driving progress. The newly developed technologies have significantly improved processing speed while maintaining key performance indicators, showcasing a major leap in off-road driving capabilities.
The implications of these advanced technologies are vast, with potential applications in industrial machinery such as excavators, dump trucks, and search vehicles. Moreover, military self-driving cars stand to benefit from enhanced safety measures and improved driving capabilities. Workers operating in off-road environments will soon enjoy a safer working environment, thanks to the integration of these cutting-edge technologies. The practical implementation of these technologies marks a significant milestone in the realm of off-road autonomous driving.
The off-road environment recognition technologies developed by the KIMM represent a paradigm shift in the field of autonomous driving. Through innovative solutions for sensor protection, cleaning, signal correction, and drivable area estimation, the research team has paved the way for safer and more efficient off-road driving experiences. The future looks promising as these technologies are set to redefine the industrial and military sectors, heralding a new era of off-road autonomous driving capabilities.
