In the lane change process, different types of drivers have behavior characteristics, same driver in road environments has not behavior, order to design model based on it is necessary study drivers' characteristics. With real vehicle data, analyzed characteristics Beijing highway, 5th rings, 4th 3rd rings and driver's environment. The results show that expected goal control total time near value, obtain corresponding lateral velocity acceleration through controlling steering wheel.
A major upgrade to the SLC final focus was installed in 1994 eliminate dominant third-order aberration of system, and thereby reduce vertical beam size at IP by a factor two. At low current, optimal about 400 nm is now routinely established, its sensitivity orbit variations, changes emittance energy spread, other parameters has been studied. For intensities above 3/spl times/10/sup 10/ particles per bunch, tuning more difficult due increased fluctuations energy, orbit, emittances....
To set up lateral safety forewarning system for adapting to different driving characteristics drivers, It is necessary classify drivers. 38 drivers’ vehicle test data are carried on factor analysis, and obtained characteristic parameters. Taking driver’ parameters as a whole, drivers analysed with hierarchical cluster analysis K‐means cluster, made comparison of two methods adjusted the class members, determined classification results determined, it provide reference control strategies...
A new structure of mechanical pulse CVT –rotational swash plate was put forward. This paper analyzed the impact helical gear parameters on characteristics, it can be seen that angular velocity output shaft is proportional to angle between Swash surface and vertical cross section input surface, modulus has no effect transmission ratio, guide rod pitch diameter major factor contacting tooth Strength, when other unchanged, ( helix angle)is torque, inversely torque.
This paper presents a driver lane change model that adapts to individuals with different driving behavior. For assistance systems, its acceptance by customers greatly relies on the assistant algorithm which can accurately reflect drivers' individual characteristics. By analyzing real world vehicle data and characteristic parameters, such as time (TTLC), steering angle lateral offset were obtained, consequently was proposed. The inputs of are vehicles' current state (e.g. velocity) parameters...
A global feedback control applied on thin film surface pattering induced by the electric field is studied theoretically near threshold of instability.The growth interfacial disturbance between air and polymer unbounded spatial domain described equation, a single nonlinear equation incorporating competition tension force; to suppress subcritical instability, thus stabilize stationary patterns developed interface.
Former lateral warning algorithms are fixed, can't adapt to different type of drivers. To warn doze off or inattention drivers, amend unconscious lane deviation and reduce departure accident, an adaptive driver characteristics algorithm was designed. The based on Time Lane Crossing(TLC) algorithm, judged intention the time sound alarm with vehicle running parameters, its' logic meets response characteristics, distinguished normal change behavior. Real road test data verified results show...
We consider the effect of van der Waals intermolecular forces on instability problems occurring in thin liquid film pattern formation induced by an electric field.The physical setup is a layer sandwiched between two electrodes and separated air gap from top mask electrode.We formulate nonlinear parabolic fourth order equation deriving forces, incorporate surface tension model.In long wavelength limit, we find that perturbations at interface undergo regulated dynamics initial thickness plays...
