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.

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.

Based on the dynamics analysis of tire blow-out vehicle, an estimated calculation model of additional yaw torque leading by tire blow-out was set up. According to the relativity between the opening duration of inflow valve of the EHB (electric-hydraulic brake system) and the pressure of the brake wheel cylinder, the estimated tire blow-out additional yaw torque was transformed into opening duration of the inflow valve, and the anti tire blow-out additional yaw torque to balance the vehicle was generated by controlling the open duration of different braking cylinders. A test system was designed, and the results show that the anti yaw torque for balancing the tire blow-out vehicle can be estimated by the calculation model, which provides a precondition to improve the response ability of the emergency braking system and precision traveling track control of tire blow-out vehicle.

Electro Hydraulic Brake (EHB) system plays an important role for improving vehicle active safety. In this paper, the dynamic behavior of EHB system is discussed. From its working principle, a dynamic model of quarter EHB system is established based on AMESim and Matlab. To analyze performance of the proposed EHB system, the strategy of Single-Neuron PID regulation is presented and a typical numerical case is given. The results show that this strategy can obtain good performance and proper parameters can improve the dynamic characteristics of EHB system effectively.

Brake Pedal Emulator plays an important role for an Electrical Brake System. A new Brake Pedal Emulator was proposed which could provide the driver controllable pedal feeling by varying solenoid current. From its working principle, an electro hydraulic dynamic model of Brake Pedal Emulator was established.

In order to improve the vehicle active safety and simplify the structure of brake system, an electro hydraulic brake (EHB) system is designed. The dynamic characteristics of EHB system is studied using theoretical and experimental method. The structure, principle and working mode of EHB system are discussed. Based on the hydraulic properties of critical components, a dynamic model of EHB system is built. Some key parameters of the model, which can't be measured, are identified using the method of linear regression parameters identification. And the model of EHB system is validated by experiment data of a test bench. Also, the influence of some factors is investigated on the dynamic performance, including accumulator pressure, PWM signal duty ratio, wheel cylinder pressure and length of pipe. Road test is carried out using BJ2500 car equipped EHB system, and results show that the dynamic response of the developed EHB system is accurate and rapid; the vehicle can be controlled smoothly and stably during braking. © 2012 Journal of Mechanical Engineering.

In this paper, the experiment for preparing C/C-SiC composites by mould pressing technology and friction and wear characteristics of composites were researched. Favorable preparation conditions of the C/C-SiC composites were investigated by orthogonal design experiment and influences of different preparation factors on the test results discussed. The wear rate of C/C-SiC composites is lowest when carbon fiber content is 60%, solution concentration is 20%, Resin:graphite powder is 5:5, content of silicon is 1. © 2015 Taylor & Francis Group, London.
