Abstract:

This article explains features and advancements in the antilock braking systems (ABS). The ABS campaign is an example of the way that advertisements can inadvertently make engineering design seem like a process of fulfilling corporate visions. An antilock braking system monitors the rotating speed of an automobile’s wheels and, when it detects a too-rapid deceleration, momentarily releases the pressure applied to the brake. As ABS developed as a device, so did the community working on it. The problem at hand and the community addressing it were defined and evolved simultaneously. Initially, a

Abstract:

Instrument panels provide the main platform for drivers to obtain all kinds of parameters of automobiles, as well as make the principal work environment where drivers steer their wheels. A properly designed instrument panel not only reduces chances of misoperation by drivers but also effectively relieves fatigue of them, thus increasing security coefficient in driving. This article makes an analysis on the ergonomics in several kinds of automobile instrument panels and gives a discussion about ergonomics in the design of automobile instrument panels and its future direction of development.

Abstract:

Vehicle security is one of the major concerns that the entire world is currently experiencing. People generally own automobiles, yet these automobiles are not always secure. Vehicle theft occurs in parking lots, public places, and other unsafe areas. The vehicle’s manufacturer does not consider the vehicle security system to be a factor in the overall cost of the vehicle. Nowadays, only a few vehicles come equipped with high-priced security systems. Door locking, alarm system, GSM, GPS, and other security features are built into high-end vehicles only. There is a necessity to build a low-cost

Abstract:

Planetary gear transmission system has been widely used in the field of aerospace equipment, automobiles, ships, etc. High power density design is an important development direction for transmission machinery, but there is a lack of systematic and deepening research in planetary gear transmission system field. Taken the most widely used 2K–H-type planetary gear transmission system as research object, a design method of high power density considering volume and efficiency is put forward. First, the transmission efficiency model of 2K–H-type planetary gear transmission system is built on the bas

Abstract:

The use of microsimulation is not prevalent in modeling transit systems. The software available is rarely capable of modeling transit systems that route vehicles in real time or systems that adjust to the level of demand. It is not straightforward to model a transit system with the available simulation packages, especially when the transit scheme is not “standard.” Even the simulation of basic schemes such as a streetcar system or a paratransit service is not an option in existing simulation software. A cursory study would reveal that simulation of any vehicle class other than personal automob

Abstract:

It is important to separate the nonmagnetic metals from shredded automobiles scraps efficiently. The research relates in general to the separation of non-magnetic metals automatically on the basis of the different density of the magnetic fluids in a magnetic field. A water-based magnetic fluid was prepared with a chemical coprecipitation method by using ultrasonic in dispersing process. The magnetic field system was design and simulated by a finite element analysis software package, ANSYS 8.1. Separation tests were performed on the mixtures of aluminum, zinc, copper and lead with various scrap

Abstract:

In this paper, a probit-based multimodal transport assignment model is developed. Three transport modes (railway system, bus system, and automobiles) and their interactions are considered. The walking time to a bus stop or a station also plays an important role in multimodal networks. Thus, walking to a bus stop or to a railway station is included in the model. The factors affecting travelers’ route choices considered in this model include actual travel times, discomfort effects on transit systems, expected waiting times, fares, and constants specific to transport modes. A route in the model m

Abstract:

A design of Controller Area Network (CAN) based longitudinal velocity measurement system using MEMS accelerometer and GPS receiver is presented. CAN is a serial communication protocol which efficiently supports distributed control system with high level of security. The system consists of a master node and a slave node built around LPC1768 and LPC2129 microcontrollers respectively. The master and slave nodes are linked with CAN bus. The slave node gets velocity data from GPS receiver and transfers to the master node. The master node samples the accelerometer output, and saves the sampled data

Abstract:

Protected intersections are used to facilitate safe crossings for non-motorized users. As a relatively new treatment in North America, it is essential to understand how their design elements, such as bicycle intersection-crossing pavement markings and corner refuge island size, enhance bicyclist safety. A driving simulation experiment was developed to test the effectiveness of different design elements of protected intersections on driver speeds. Participants were exposed to different protected intersection designs that varied with respect to the corner refuge island width and bicycle intersec

Abstract:

In recent years, the number of automobiles has been steadily increasing, which has significantly impacted on the society and human life, and led to many social problems such as fuel crisis, environment pollution. Therefore, lightweight designing becomes a focused issue. Lightweight materials application, optimized structure design and advanced manufacturing process are the main ways to achieve the lightweight. However, low plasticity and ductility of high strength steel constrain the application of high strength steel. In this paper, the basic principle of roll forming for automotive parts is

Engineers and materials scientists are constantly working to improve the quality of our built environments and vehicles, including noise levels and vibration. The researchers pursuing the duel goals of safety and comfort are increasingly being challenged as the projects they work on advance technologically, in size and are constructed with new materials. Buildings grow taller and must compensate for greater movement and vibrations from wind or shifting foundations. Cars especially are undergoing drastic changes that require a rethinking of the material and designs of their frames, panels, door
