*Advanced Driving Assistance System (ADAS) provides warning and automatic control intervention to a human driver for accident avoidance and collision mitigation. To both minimize the human-machine conflict and enhance human trust in the driving assistance system, ADAS should take personalized driving characteristics into account to support a particular driver in an optimal manner. Typical Personalized Driving Assistance System (PDAS) trains a driver model offline via complicated machine learning algorithms and assumes that the trained driver model maintains reliable until the next model retraining phase. However, even for a specific driver, its driving style can vary substantially due to various factors, e.g., daily mood variation, weather condition, and hardware adaption. Therefore, physics-based driver model parameter identification has been applied to achieve an authentic PDAS. The commonly employed online driver model parameter identification approach is the Least Square (LS) method. However, LS, leaning on the classical Persistence of Excitation (PE) condition, may have slow estimation convergence and be sensitive to measurement noise. Alternatively, this paper proposes a purely algebraic method for driver model parameter identification. This new approach can achieve almost instantaneous multiple parameters identification and is robust to measurement noise. Simulink-Carsim joint simulations demonstrate the excellent performance of the proposed algorithm.*

DSCC2020 - Virtual Conference

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
