Researchers at Daegu Gyeongbuk Institute of Science and Technology (DGIST) have developed a \u201cphysical artificial intelligence\u201d vehicle state estimation system designed to track how an electric vehicle moves in real time, with a focus on motion states that are difficult to measure directly.\u00a0<\/p>\n
Vehicle state estimation is a core part of modern stability control and automated driving because control systems rely on accurate, up-to-date information about vehicle motion while braking, steering, and cornering.\u00a0<\/p>\n
DGIST said the work was led by Professor Kanghyun Nam and carried out with international collaborators including Shanghai Jiao Tong University and the University of Tokyo.<\/p>\n
The goal was to improve estimation accuracy under real-world conditions where road friction, tire deformation, and rapid maneuvers can reduce the reliability of conventional model-only approaches.\u00a0<\/p>\n
A key target for the system is the sideslip angle, which describes how much a vehicle is sliding sideways relative to its direction of travel, especially during turns or on low-friction surfaces. Estimating this value quickly is important because delayed detection can limit how effectively a control system can respond.\u00a0<\/p>\n
The method combines a physical tire model with a data-driven component based on Gaussian process regression, then fuses the information using an unscented Kalman filter.<\/p>\n
DGIST said the framework continuously uses sensor inputs, including measurements related to lateral tire force, to adapt to changes in tire behavior and driving conditions.\u00a0<\/p>\n
DGIST said the team validated the approach using an electric vehicle platform across multiple road surfaces, speeds, and cornering scenarios, and reported consistent estimation performance across the tested conditions.\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"
