By new advancements in vehicle manufacturing vehicle quality evaluation and assurance has become a more critical issue. In present work, the vibration transfer path analysis and vibration path ranking of a car interior has been performed. The method is similar to classical multilevel TPA methods but has distinct differences. The method is named VIVS which stands for Vehicle Interior Vibratio...

In this paper we introduce a dynamic vehicle routing problem in which there are multiple vehicles and multiple priority classes of service demands. Service demands of each priority class arrive in the environment randomly over time and require a random amount of on-site service that is characteristic of the class. To service a demand, one of the vehicles must travel to the demand location and r...

In order to improve the dynamic performance and endurance mileage of vehicle, operation mode and parameter matching were analyzed and designed on a novel power transmission scheme of range-extended electric vehicle (R-EEV), and the following control strategy of the engine optimization curve was proposed. The simulation was carried out on the Matlab/Simulink software platform and the results sho...

Engine mathematical model can be used to simulate vehicle dynamic performance and fuel economy for vehicle design. Simulation of vehicle dynamic performance and fuel economy is based on mathematical model of engine. Least square method and multiple regression analysis were used to fit curve of external characteristics and universal characteristics when the test data of external characteristics ...

We present MENSA (Mission Effectiveness and Safety Assessment), a health monitoring and contingency resolution system architecture that supports unmanned vehicle self-awareness with respect to the vehicle's ability to carry out its missions. MENSA analyzes mission plans to identify required vehicle capabilities. Throughout the mission, MENSA monitors onboard sensors to diagnose faults and maps ...

This paper compares two optimal energy management methods for parallel hybrid electric vehicles using an Automatic Manual Transmission (AMT). A control-oriented model of the powertrain and vehicle dynamics is built first. The energy management is formulated as a typical optimal control problem to trade off the fuel consumption and gear shifting frequency under admissible constraints. The Dynami...

A self-aware aerospace vehicle can dynamically adapt the way it performs missions by gathering information about itself and its surroundings and responding intelligently. We consider the specific challenge of an unmanned aerial vehicle that can dynamically and autonomously sense its structural state and re-plan its mission according to its estimated current structural health. The challenge is t...

Control of Underwater vehicle manipulator systems (UVMS) are limited to human intervened tele operation in almost all practical applications. Extending these missions to autonomous or semi autonomous operation requires accurate dynamic modeling of the system. Such modeling assists system design and controller testing of autonomous UVMS. The study performs a dynamic analysis to capture relative ...

This paper considers stochastic load-constrained vehicle routing systems in which a fleet of homogeneous vehicles is dispatched from a central depot to serve the demands of surrounding customers. Customer locations and load sizes are known only in distribution before operations. Variants of this problem are often treated with very simple uncoordinated operating schemes, which are mathematically...

In this paper we describe REVAMP, a mixed-initiative tool for real-time management of paratransit vehicle schedules. Like many applications, paratransit scheduling is a dynamic, execution-driven process, where unexpected events (e.g., traffic, breakdowns, new requests, cancelations) continually force changes to precomputed schedules. The design of REVAMP aims at support for this dynamic, real-t...
