The document summarizes research on a regenerative braking system implemented in a hybrid vehicle. A dynamo is fixed to the rear wheel to convert kinetic energy during braking into electrical energy stored in the vehicle's battery. Testing showed the regenerative braking system reduces braking time and distance compared to a vehicle without regenerative braking. Analysis of speed, time, distance and current during braking supported the improved efficiency of capturing energy normally lost during braking. The document discusses the components used, formulas, results of implementing regenerative braking, and potential future improvements to increase energy recovery.
The document provides an overview of compressed air engines. It discusses how pneumatic motors use compressed air to create motion. It outlines the history of compressed air vehicles in the 1840s and recent developments by companies like EngineAir and MDI. The document discusses converting internal combustion engines to run on compressed air by replacing components like the fuel tank and spark plug. It also reviews literature on compressed air engines and discusses technical benefits like reduced temperature but also limitations like limited storage capacity and range.
This document discusses hybrid vehicles. It defines a hybrid vehicle as one that uses both an internal combustion engine and electric motor to propel the vehicle. It classifies hybrids into three types: series, parallel, and series-parallel. Hybrids improve fuel efficiency and reduce emissions by capturing energy through regenerative braking and using batteries to assist the gasoline engine. While hybrids currently have higher costs, the document argues they will play an important role in reducing dependence on oil and mitigating global warming.
The basic knowledge about power steering's have been illustrated with animations. Why do we need it and how to improve the steering system has change the automobile industry.
This document discusses various aspects of automobile safety, including active safety features that help prevent crashes (e.g. brakes, lights), passive safety features that protect during crashes (e.g. airbags, seatbelts), and safety issues for different demographic groups (e.g. teens, elderly). It provides detailed lists and explanations of active safety technologies like driver assistance systems, crashworthiness features, and factors that influence safety like vehicle color. International safety trends over time and differences between countries are also reviewed.
A regenerative brake system converts the kinetic energy of a moving vehicle into other forms of energy through different mechanisms. There are three main types: electric energy storage which uses a motor-generator and batteries; compressed gas storage which uses a flywheel; and hydraulic storage which uses a pump and accumulator tank. These systems can capture 50-70% of the energy lost during braking to improve efficiency. The optimal system captures energy hydraulically and uses it to power an electric motor for hybrid or electric vehicles.

The document discusses PWM control of servo motors using the S3C6410 microprocessor. It describes how the S3C6410 contains timers that can generate PWM signals to control servo position and speed. It provides code examples for initializing the timers for PWM output and setting the register values to control the duty cycle and period of the PWM signal. User space code is also shown for opening and configuring the PWM device files.
