The purpose of this game theory-based trajectory tracking control study driverless cars is to resolve the conflicting problems precision in and drive stability for lane change situations. general plan made. lateral based on theory evolutionary games, linear quadratic regulator (LQR) a method with predictive feedforward. When it comes dynamic systems that vary over time, are both sides same coin. payoff matrix first constructed determine utility function, followed by dynamical replication...

Abstract Mountainous highway slopes are characterized by their point-like distribution, large number, relatively small scale, and susceptibility to human activities environmental changes. Overall monitoring assessment of necessary detect hazards in a timely manner prepare disaster prevention measures advance. There is lack integration utilization data, the slope safety evaluation system not mature. In response these problems, this study uses real-time data as research object. Real-time...

In order to alleviate the adverse effects of uncertainty in active front steering (AFS) system, a new type observer is designed this paper that can simultaneously estimate sideslip angle and disturbance, which provides controller with accurate compensation simplifies system model. addition, an based on adaptive fuzzy sliding mode (AFSM) proposed, uses algorithms adjust update parameters real time. The stability closed-loop AFS Lyapunov theory analyzed. Compared traditional PI control,...

A game theory based trajectory tracking control method is studied for the dual-objective optimization problem of accuracy and driving stability driverless electric formula racing cars in high-speed conditions. The general strategy model predictive controller on evolutionary between two players are designed to optimize their own decisions achieve optimal payoff themselves, obtain solution problem, by taking dual objectives as game. Considering influence dynamic environment, time-varying...

Dual-response surface method is a powerful for simultaneously optimizing the mean and variance of responses in quality engineering, which minimization squared error (MSE) an effective approach. To date, relative weights bias have been equally set or determined only by data. However, should be according to tradeoffs on decision maker's preference. In this paper, we proposed optimal weighted approach determine based both preference structure addition, examples are given illustrate compared...

With rapid development of intelligent vehicles, a wide range wireless devices, such as radio reception (FM), navigation systems (GPS), satellite radio, mobile telephone, radars, are being installed. Driving safety is more and affected by the performance these devices. Design Validation & Product tests, which vital to mainly bench tests on-road for systems. However, open testing environment will unavoidably lead test inconsistency due diversity in humidity, temperature, shading condition...

Engine oil consumption is an important source of hydrocarbon and particulate emissions in modern automobile engines. Great efforts are being made recent years to minimize the impact on engine emissions. Research engineers continue study sources driving mechanisms consumption. Of these mechanisms, contribution from Positive Crankcase Ventilation (PCV) system least investigated. However, studies have shown that blowby could be significant under certain conditions. The PCV refers vents gases...

Based on the theory of HEV (Hybrid Electric Vehicle) and idea reverse simulation, simulation model parallel is established in MATLAB estimation energy efficiency, power performance fuel economy achieved, which provides reference for HEV. At same time definition estimating method about efficiency were mentioned this paper can be achieved by model. The results show that has certain practicability convenience.

Unmanned fully line-controlled distributed drive electric vehicles with four-wheel independent drive, dependent braking and steering have significant advantages over conventional in terms of dynamic control, but at the same time multiple actuators degrees freedom also pose risk failure system, which is studied this paper for trajectory tracking control. Rational control systems such as braking, fault tolerance unmanned are carried out. For longitudinal a fuzzy PI algorithm used to input...
