This paper proposes a dynamic optimization–simulation model as a decision support system for one-way carsharing organizations. To reduce the vehicle imbalance in one-way systems, a Vehicle Relocation Optimization model is solved successively in a discrete event simulation. Each event is the arrival of a new user. The model is compared to an a priori benchmark model. Autoshare is chosen as a cas...

MPC (Model Predictive Control) techniques, with constraints, are applied to a nonlinear vehicle model for the development of an ACC (Adaptive Cruise Control) system for transitional manoeuvres. The dynamic model of the vehicle is developed in the continuous-time domain and captures the real dynamics of the sub-vehicle models for steady-state and transient operations. A parametric study for the ...

For the purpose of reproducing complex vehicle-pedestrian interactions using a simplified and standardized vehicle model, a previous study has developed a computational model for a generic buck to reproduce car-small sedan interaction using a standardized vehicle front model. Although the previous study validated the buck model using a finite element (FE) model for a pedestrian dummy in terms o...

This paper considers two different methods of using a dynamic vehicle model in order to aid pose estimates provided by an Inertial Navigation System (INS) for a Un-manned Aerial Vehicle (UAV). We consider low-cost inertial sensors in which errors from sensor noise, bias and scale-factor errors cause a significant growth in pose estimate errors when the navigation system is un-aided by external ...

In vehicle crashworthiness design optimization detailed system evaluation capable of producing reliable results are basically achieved through high-order numerical computational (HNC) models such as the dynamic finite element model, mesh-free model etc. However the application of these models especially during optimization studies is basically challenged by their inherent high demand on computa...

this paper considers the multi-depot vehicle routing problem with time window in which each vehicle starts from a depot and there is no need to return to its primary depot after serving customers. the mathematical model which is developed by new approach aims to minimizing the transportation cost including the travelled distance, the latest and the earliest arrival time penalties. furthermore, ...

This analysis examines how the age of the vehicle at the time of the crash and the vehicle’s model year are correlated with the injury outcome of the driver of a passenger vehicle involved in a fatal crash. A multivariate logistic regression model was constructed to model the relationship between injury outcome (fatally injured versus survived) of the driver and the independent variables vehicl...

A bstmct— This paper proposes a new Hm yawmoment control scheme using brake torque for improving vehicle performance and stability especially in high speed driving. Its characteristics is that only one brake is used for control depending on the vehicle state. Steering angles are modeled as a disturbance input to the system and the controller minimizes the difference between the performance of t...

in addition to increment of the vehicle sprung mass, the main physical effects of addition of cng tank to the vehicle are the longitudinal and height displacement of center of gravity, which have the most influences on the handling, braking, roll stability and spin stability of the vehicle. increment of cng tank mass to the sprung mass of the vehicle increases the vehicle under-steer gradient, ...
