An effective lane boundaries projective model (LBPM) and improved detection method in the images captured with a vehicle-mounted monocular camera in complex environments, especially for sharp circular curve lane, is proposed in this paper. Firstly, a lane boundaries projective model is deduced. This lane model can not only express straight-line lane boundaries, but also describe the actual sharp circular...
Idle stop-start system is a new energy-saving product, which can obtain a good fuel economy and reduce emissions for the city bus. The work principle and mechanical structure are analyzed in this paper. The key technologies of idle-stop-start system are analyzed based on this. Then the idle-stop-start system is modeled and analysised based on AVL Cruise. Last, the fuel economy is simulated and analysised...
Presented the shift points determining method of the power shift schedule when the traction power curve does not intersect under the adjacent shift of the same throttle. Established the transmission system mathematics model. Built a software in-the-loop simulation platform with Matlab/Simulink, and simulate the process of the vehicle continuous upshift. The simulation results showed that the power...
Most literatures of Inventory-Routing problems find the solutions by simulation, but few solve the real case problem of logistics companies. This research will apply some specific real logistics company's operating data to study the Inventory-Routing problem. This study first develops a mathematical model for this Inventory-Routing problem, next applies Savings method, 2-opt heuristic method and 1-1...
An electric vehicle driven by two rear motors uses a new drivetrain configuration, which can not only eliminate the traditional drivetrain components, but also improve handling characteristics. A five-degree-of-freedom model of an electric vehicle is established, in which lateral motion, yaw motion, roll motion and rotary motion of two driving wheels are all considered, besides, slip ratio of wheels...
