This paper presents a full drive-by-wire vehicle named Urban Future Electric Vehicle (UFEV) and introduces the detailed design of its vehicle control unit (VCU). The LabVIEW and PXI solution is selected for the rapid prototyping of VCU, which also acts as a real-time test, measurement and control platform for UFEV. To address its unique features, the design and transition of specific driving modes are introduced. Experiments show that omnidirectional moving can be implemented accurately and reliably by using the proposed design. © (2013) Trans Tech Publications, Switzerland. Source

Rear-end collisions of low speed vehicles on the urban road are common accident scenarios. A judgment of safety distance is a crucial part of a rear-end collision avoidance system which relies on safety distance model. In order to solve the problems of traditional safety distance models, this paper proposes a new model to avoid rear-end collisions. The new model considers the braking performance of the host vehicle and the motion state of the heading vehicle. Then a rear-end collision avoidance system including the new model is established using a combination of CarSim with Simulink software. Three typical working conditions through the co-simulation is simulated for verifying the model. Simulation results show that the new model ensures rear-end collision can be avoided, meanwhile keeping a short relative distance that improves road efficiency. © (2013) Trans Tech Publications, Switzerland.

Self-piercing riveting is a high-speed mechanical fastening technique for joining sheet-material components. In recent years, the development of the self-piercing riveting technology has broadened the application of the technology in the automobile industry. In this paper, a new method of joining metal sheets using a short pipe rivet with inner flange is proposed. Self-pierce riveting with inner flange pipe rivet is used to joint Al6063 aluminum alloy sheets. Riveting process is presented. Different parameters of rivet height, rivet diameter, rivet end angle and rivet wall thickness are combined to obtain forming laws and static mechanical performance. Tensile tests of the lap joints, coach peel joints and cross joints of self-piercing riveting with inner flange pipe rivet are carried out. The effects of rivet heights, diameters, end angle and rivet wall thickness on tensile strength are explored. © 2014 The Authors. Published by Elsevier Ltd. Source
