Global Positioning System (GPS) defects lead the necessity of inertial positioning. Then analysis of the errors that may exist while installing or using inertial sensors to realize vehicle positioning is presented. Combined with the mechanism of error generation, an approach to correct the error which influences the vehicle positioning most is proposed. Finally, the field test results are given to...
This paper studies the optimal sizing and the experimental verification of a vehicle-used hybrid energy storage system (HESS). To determine the optimized combination that maximizes the traveling distance at an FTP driving pattern, an exhaustive search method was employed. Under constraints of cost, vehicle acceleration, and HESS gross weight, the optimal sizing can be derived. Next, for the purpose...
For verifying the strategy of the vehicle control unit(VCU), a real-time simulation environment needs to be established in advance. It is modified from our in-house simulator for the electric vehicle (EV) based on the hardware in-the-loop(HIL) structure and constrained by several communication devices, e.g. CAN bus, AI/O, DI/O, etc.. A dual energy storage system (DESS) has been modeled in this simulator...
To alleviate the traffic imbalance between supply and demand for over-saturated complex intersections, based on disconnected traffic flow characteristics between urban roads, this article aims at the focus of conflict between supply and demand - supersaturated vehicle columns in sections connecting to crossroads, analyzing complex intersections traffic capacity impairment mechanism arising out of...
