EBS (electronic brake system) can effectively control and adjust braking force acting on every wheel, reduce braking response time and braking distance, and make vehicle achieve much more braking stability. It is featured with CAN (Controller Area Network) communication by which the sensor signals and control command signals can be transmitted and received. In the braking performance test of EBS, conventional test methods have some inconvenience in existence. For example, the fixing of pressure sensors and wheel speed sensors is restrained by the installation position, and the precision of measuring is prone to be affected by the environment conditions. But based on CAN communication technology, the special testing instrument can be connected with CAN bus, monitoring and recording signals on the bus. Thus signals representing braking performance can be acquired through CAN bus.
电子制动系统(EBS)可以有效地控制和调节作用在各个车轮上的制动力，缩短制动响应时间和制动距离，使车辆获得更大的制动稳定性。它具有CAN (Controller Area Network，控制器局域网)通信功能，可以收发传感器信号和控制命令信号。在EBS的制动性能测试中，传统的测试方法存在一定的不便。例如，压力传感器和轮速传感器的固定受到安装位置的限制，测量精度容易受到环境条件的影响。而基于CAN通信技术的专用测试仪可以与CAN总线连接，对总线上的信号进行监控和记录。因此，可以通过can总线获取代表制动性能的信号。

This paper presents a modern approach of speed control for permanent magnet synchronous motor (PMSM) applied for electric vehicle using a nonlinear control. The regulation algorithms are based on the input-output feedback linearization technique. The direct component of the current is controlled to be zero which insures the maximum torque operation. The near unity power factor operation is also achieved. Moreover, among EV's motor electric propulsion features, the energy efficiency is a basic characteristic that is influenced by vehicle dynamics and system architecture. For this reason, the EV dynamics are taken into account. Simulation tests have been carried out on a 19.8-kW EV PMSM drive to evaluate the consistency and the performance of the proposed control approach.

A new capacitor clamped modular dc-dc converter with bi-directional power handling capability will be presented in this paper. This inductor-free design is modular, and it is possible to integrate multiple loads and sources simultaneously in the converter. Moreover, this 5 kW dc-dc converter can produce multiple ac outputs to feed power to ac loads or transformers to get further control over the conversion ratio of the circuit. This high efficiency modular converter has flexible conversion ratio, and it could be successfully used in a multi-bus power system by virtue of its inherent power management properties.

This paper analyzes the input admittance/impedance characteristics of a permanent-magnet brushless AC motor drive system, taking account of the influence of both current and speed control loops as well as the motor and inverter losses. It is shown that, if voltage feedforward compensation is not employed, the input admittance of the drive system differs significantly from that of an ideal constant power load, and is influenced by the speed and current control loop bandwidths. It is also shown that, when the drive is connected to a DC supply via an LRC filter, the magnitude of the input admittance at the filter resonant frequency has a crucial effect on system stability margin.

Motor cycles are one of the major sources of air pollution in crowded cities. In order to alleviate this problem, instead of the internal combustion engines new technologies such as pure PEM fuel cell system or hybrid system can be utilized. In this paper, a hybrid fuel cell system has been modeled and optimized. This system includes fuel cell stack, compressor, humidifier, pump, blower, hydrogen storage tank and chemical battery. After optimization, by using the Simulink software the system performance under the standard driving cycle (FTP75) has been simulated and the results of that have been compared with the non-hybrid system.

In this paper an efficient high power high-step up dc- dc converter is presented for interfacing distributed energy storage elements like, fuel cells, batteries, and ultracapacitors with the high voltage dc bus in Electrical Vehicles (EV) and Hybrid Electric Vehicles (HEV). In the proposed converter, coupled-inductor boost converters are interleaved and a boost converter is used to clamp the switch voltage of the interleaved converters at a lower voltage. Leakage energy of all the interleaved converters are gathered in one clamping capacitor and discharged to the output by the clamping boost converter. The interleaving and low voltage clamping of coupled-inductor boost converters enable to achieve high efficiency. Design and analysis of the proposed converter are presented. Finally simulation results are provided for verification of the proposed converter.

A lot of conventional automotive components driven by mechanical power source are being replaced with electrical ones to comply with the demands of market and customer, therefore the amount of electric energy used in a vehicle will be increased continuously. The increment of electric power demand causes interest on new higher power system such as 42V Power Net, and furthermore necessity for development of energy storage device is highlighted recently. The electro- hydraulic power steering (EHPS) system is one of them. This paper presents the development of the electric driven pump unit for EHPS system of 42V automobile, which is to install interior type permanent magnet synchronous motor.

Like with the passenger car and transit bus markets, school buses can benefit from plug-in hybrid technology. Advanced energy corporation established the plug-in hybrid electric school bus (HESB) project to create the demand for plug-in hybrid school buses required for a bus manufacturer to invest in the development of this technology. Nationwide 12 school districts in NY, PA, VA, DC, NC, SC, FL, IA, AK, TX, WA, and CA have purchased 19 plug-in hybrid buses in the project with all buses to be delivered by the end of 2007. Each bus is a type-C school bus with a VT365, 200-215 hp diesel engine by IC Corporation, a 25/80-kW AC induction motor and hybrid drivetrain from Enova Systems, and a 330-V Li-ion battery pack from Valence Technologies. The total cost of each bus ranges from $200,000-$220,000, including an estimated $140,000 premium for the plug-in hybrid system. This paper addresses the specific challenges that face the transportation industry as a whole, summarizes earlier studies that demonstrate the technical and economical feasibility of plug-in hybrid school buses, describes the HESB project, and draws future plans to show why hybrids are an excellent solution for the school bus market.
