A 3-degree of freedom (DOF) nonlinear model including yaw, lateral, and roll motions was constructed, a numerical simulation chaotic behavior performed using the Lyapunov exponent method. The vehicle motion is complex, manifesting double-periodic, quasi-periodic, phases, which negatively affects lateral stability. To control this behavior, controller designed based on sliding mode variable structure (SM-VSC) decrease chattering further improve stability under extreme operating conditions,...
In this paper, a new curve-lane recognition algorithm is proposed. The uses edge point curvature voting to determine the region of interest based on near-vision straight-lane information. First, information detected in area regarding straight lines left and right current lane. Near-vision lane-line extraction includes lane image filtering, as well detection below vanishing line. positioned by determining position distribution direction angle. addition, line extracted point. that are...
Hyperoside, 3′-O-methylquercetin 3-O-β-D-galactopyranoside, astragalin and 3-O-β-D-glucopyranoside from an invasive weed Solanum rostratum Dunal were separated purified successfully by high-speed counter-current chromatography (HSCCC) with a solvent system composed of n-hexane-ethyl acetate–methanol–water (1:7:1:7, v/v) gradient elution mode preparative high-performance liquid (prep-HPLC) low column temperature. In the sample pretreatment section, target compounds in aqueous extract...
Abstract:According to the shortcoming that safety of lane change is difficult ensure for different changing environments in most studies, a control method based on vehicle driving safe boundary proposed solve this problem.Firstly, accounting space and collision time interval between self-vehicle surrounding associated vehicles, state decision designed.Secondly, position considering vehicle-road relationship rectangular area established.Based stability limit requirements yaw rate states,...
Through the analysis of main types accidents and three basic driving behavior in high-speed condition, it was concluded that steering system has both discrete state continuous state. And then a multi-mode-switching control strategy proposed, which used time to line crossing (TLC) safe distance as switching rules. The damping, lane-keeping lane-changing controller were designed respectively implemented on steer-by-wire system. In model, new method is introduced first derivative second lateral...
In complex outdoor environments, the conventional control methods which use dynamic model were hard to satisfy special requirement of mobile robots. this paper, composite method includes CMAC neural network and Fuzzy was constructed. The improves self-learning ability controller when input signal change unpredictability, fuzzy logic used simulate experience experts intuition human brain, maintain stability robustness system in rural environment. experiments showed that could improve high...
