In this project a new integrated multi level AC-DC converter is proposed. The proposed converter has two independent controllers. First controller is used to control the input side and the second for the output side. The input controller prevents DC bus voltage from becoming excessive and performs power factor correction and regulates DC bus voltage. The output controller regulates output volta...

This article is the result of a case study on ergonomic work analysis carried out in an urban bus company located in Ilha do Governador, Rio de Janeiro. The methodology used in this work follows the French-tradition Ergonomic Analysis of the Work (EWA) combined with the best tradition from anglo-saxon ergonomic work analysis. The situated diagnosis was performed to provide relevant information ...

Modern safety systems are transforming vehicles from human-controlled passive devices into human-centric intelligent/ active systems. There is a wide range of systems from fully autonomous vehicles to humanaugmented control devices which have emerged in this field. In current trends, co-operative active systems have the driver in the decision and control processes are favored for their ‘human-c...

Bus-driver’s task is to manoeuvre their bus through the chaotic reality on the roads, in a predictable way (following the timetables). In order to do so the bus-driver is equipped with various tools including a communication system. It has become evident that this communication system is inadequate to support the drivers' efforts to create efficient traffic flow. Facing a new generation of comm...

This paper aims to present and evaluate the performance of one of the first real-time bus dispatching system in Bangkok, Thailand. The proposed bus dispatching system receives the real-time bus location data from the RFID sensor network. The paper provides the background and brief description of both the hardware and architecture of the RFID sensor network and the real-time bus dispatching syst...

This paper reports on one of a number of parallel investigations being undertaken into alternative approaches to solving part or the whole of the bus driver scheduling problem. An arti cial ant system is set up, with ants following trails through a network, each trail representing a complete bus driver schedule. Initial schedules are set up by drawing from shifts generated by other systems avai...

This paper presents the development of an experimental platform to test a real-time controller for a small Permanent Magnetic Brushless Direct Current (PM BLDC) motor using a Controller Area Network (CAN) communication bus. The CAN communication bus transmits and receives information between modules to control the speed, acceleration/deceleration, and rotational direction of the motor. The desi...

In the development of driver adaptive and context aware active safety applications, driver–vehicle interaction signals offer excellent opportunities for advanced system design, yet limited progress has been realised. The implementation of driver adaptive and context aware systems requires longer time windows to analyse the current status of the driver and/or traffic situation ahead. In this stu...

A driver behaviour analysis tool is presented. The proposal offers a novel contribution based on low-cost hardware and advanced software capabilities based on data fusion. The device takes advantage of the information provided by the in-vehicle sensors using Controller Area Network Bus (CAN-BUS), an Inertial Measurement Unit (IMU) and a GPS. By fusing this information, the system can infer the ...
