This paper presents a novel vehicular adaptive cruise control (ACC) system that can comprehensively address issues of tracking capability, fuel economy and driver desired response. A hierarchical control architecture is utilized in which a lower controller compensates for nonlinear vehicle dynamics and enables tracking of desired acceleration. The upper(More)
In addition to decentralized controllers, the information flow among vehicles can significantly affect the dynamics of a platoon. This paper studies the influence of information flow topology on the internal stability and scalability of homogeneous vehicular platoons moving in a rigid formation. A linearized vehicle longitudinal dynamic model is derived(More)
Battery State of Charge (SOC) estimation is an important function for battery management systems and critical for the reliable operations of batteries. This paper analyzes the robustness of SOC estimation algorithms for two types of Li-ion batteries under varying loading conditions, temperatures and aging levels. Based on the model templates identified in(More)

The platooning of autonomous ground vehicles has potential to largely benefit the road traffic, including enhancing highway safety, improving traffic utility and reducing fuel consumption. The main goal of platoon control is to ensure all the vehicles in the same group to move at consensual speed while maintaining desired spaces between adjacent vehicles.(More)
Besides automated controllers, the information flow among vehicles can significantly affect the dynamics of a platoon. This paper studies the influence of information flow topology on the closed-loop stability of homogeneous vehicular platoon moving in a rigid formation. A linearized vehicle longitudinal dynamic model is derived using the exact feedback(More)
Fuel consumption of traditional ground vehicles is significantly affected by how the vehicles are driven. This paper focuses on the servo-loop control design of a Pulse-and-Gliding (PnG) strategy to minimize fuel consumption in automated car following. A switching-based framework is proposed for real-time implementation. The corresponding controller was(More)
Battery management system monitors and mitigates the operation of battery cells and stacks and is important for battery safety and reliability. This paper presents a dual-objective optimal charging strategy for two types of Li-ion batteries, which considers the conflict objectives of charging time and charging loss. The battery models developed in a prior(More)
BACKGROUND/AIMS To investigate the effect of miR-18a on angiogenesis in gastric cancer. METHODOLOGY We generated stable cell lines overexpressing miR-18a in SGC-7901 cells. Cell proliferation was assessed by the MTT assay. The effects of miR-18a overexpression on tumor growth and angiogenesis were assessed. Because of the key role of mammalian target of(More)
