This paper presents a new shared lateral control approach to deal with the transition management between human driver and autonomous system. The objective of this is realize smooth safe switching two agents steering inputs during lane keeping maneuver. different driving modes including system are detailed. Two defined. acts on vehicle's control. consists longitudinal controller developed based ...

BACKGROUND A noninvasive system for determining left ventricular (LV) filling pressure may help to improve personalized fluid removal goals in hemodialysis patients. We previously showed that the change in photoplethysmography (PPG) pulse amplitude measured by finger PPG during a Valsalva maneuver correlates with invasively measured left ventricular end-diastolic pressure (LVEDP). This key PPG ...

Path tracking plays a crucial role in autonomous driving. In order to ensure the real-time performance of controller and at same time improve stability adaptability path controller, lateral control strategy based on improved LQR algorithm is proposed this paper. To begin with, discrete with feedforward feedback components designed error model vehicle dynamics constructed by natural coordinate s...

The merging process in an Automated Highway System (AHS) is divided into a speed adjustment stage and a lane merging stage. Three important parameters, namely, acceptability, availability and pursuability, are analyzed to characterize the AHS lane gap features for the ideal, smooth and safe merging of the ramp vehicles. Three control guidance laws, namely, linear, optimal and parabolic speed pr...

Connected Automated Vehicles (CAVs) have the potential to improve traffic operations when they cooperatively maneuver in merging sections. State-of-the-art approaches cooperative either build on heuristics solutions or prohibit mainline CAVs change lane multilane highways. This paper proposes a hierarchical control approach that ensures collision-free and traffic-efficient through interaction o...

Maneuver detection is a very important task for maintaining the catalog of the orbital objects and space situational awareness. This paper mainly focuses on the typical maneuver scenario, where space objects only perform tangential orbital maneuvers during a relative long gap. Particularly, only two classical and commonly applied orbital transition manners are considered, i.e. the twice tangent...

The left turn lane capacity is highly influenced by the presence of pedestrians under shared signal phasing. Pedestrian crossing time can be pedestrian platoon maneuver influence traffic settings, crosswalk length and bidirectional interactions pedestrian, due to that turning vehicles movement may significantly affected. However, existing estimation methods lanes did not consider those factors....

The master thesis in this report has been made in cooperation between Scania CV AB in Södertälje and the department of machine design at KTH in Stockholm. Scania CV AB is a leading manufacturer of heavy trucks, buses and coaches, and industrialand marine engines. Increasing road safety demands for vehicles in development has resulted in a new generation of safety systems, called Advanced Driver...

PURPOSE The aim of our study was to assess the hemodynamic change of liver during the Valsalva maneuver using Doppler ultrasonography. METHODS Thirty healthy men volunteers were enrolled (mean age, 25.5±3.64 years). The diameter, minimal and maximal velocities, and volume flow of intrahepatic inferior vena cava (IVC), middle hepatic vein (MHV), and right main portal vein (RMPV) was measured d...

Vehicle bypassing is known to increase delays at traffic diverges. However, due the complexities of this phenomenon, accurate and yet simple models such lane change maneuvers are hard develop. In work, we present a macroscopic model for predicting number vehicles that perform bypass diverge when taking an exit link. We interpret maneuver as drivers acting selfishly; every vehicle selects lanes ...
