Abstract

The invention provides a self-powered vehicle sensor system. A vehicle system is provided. The vehicle system includes a vehicle suspension apparatus configured for movement during vehicle travel; an energy harvesting device mounted on the vehicle suspension apparatus and configured to generate electrical energy in response to the movement of the vehicle suspension apparatus; and a sensor mounted on the vehicle suspension apparatus and coupled to the energy harvesting device for receiving the electrical energy.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 251,395, filed October 14, 2009, the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates generally to sensor systems in motor vehicles, and more particularly to a sensor system in motor vehicles powered by harvesting energy from vehicle vibrations. Background technique [0004] The ever-increasing demand for better fuel economy has led to the improvement and development of hybrid vehicles, electric vehicles, and vehicles powered by fuel cells or diesel fuel. Efforts by automakers to increase fuel economy include weight reduction, improved aerodynamics, active fuel management, and hybrid engines. However, there is an ongoing search for other mechanisms, techniques, and energy sources that can improve fuel economy. [0005] It is generally known that vehicles are subject to vibrations, es...
