Based on the neural network (NN) technique, a new sound quality evaluation (SQE) model for synthetical annoyance of vehicle noises is proposed in this paper. Based on the measured noise signals of a sample vehicle, the psychoacoustical models for loudness, sharpness and roughness are investigated. Annoyance values of the measured vehicle noises are estimated by a jury test following an anchor-s...

The use of driving simulation in vehicle design and development is growing. For maximal benefit, vehicle models used in the driving simulator must be rapidly reconfigurable and easy to develop. To evaluate potential modeling concepts, vehicle dynamics and vehicle subsystems are developed using modular model components. These are integrated with simulator cueing subsystems, using the same modeli...

This paper presents an application of the nonlinear optimal control techniques to the design of launch vehicle autopilots. The optimal control is given by the solution to the Hamilton-Jacobi-Bellman (HJB) equation, which in this case cannot be solved explicity. A method based upon Successive Galerkin Approximation (SGA), is used to obtain an approximate optimal solution. Simulation results invo...

ESP is an active safety system for road vehicles to control the dynamic vehicle motion in emergency, the composition and working principle of ESP were introduced in the paper, and the control technology of ESP was studied too. A virtual prototype model of a vehicle model was built in ADAMS/Car, and the yaw fuzzy control co-simulation model of vehicle was established in Matlab/Simulink, to study...

This paper focuses on vehicle mobility analysis in VANET. The performance of vehicle mobility in terms of average inter-vehicle link available time and the average number of inter-vehicle link changes for maintaining an active link in VANET is analyzed using both handover model and random moving model, respectively. The theoretical analysis is verified by simulation experiments. The numerical r...

A novel vehicle stability control method integrated direct yaw moment control (DYC) with active front steering (AFS) is presented in this paper. By the phase plane of sideslip angle and sideslip angular velocity, vehicle stable region is determined. When the vehicle is outside the stable region, DYC controller is firstly used to produce proper direct yaw moment, which can make the vehicle back ...
