Drive-by-wire

Drive-by-wire systems are based on technology that was originally developed in the aerospace industry. Drive-by-wire systems result in less vehicle weight up to 10 kilograms for brake systems alone but not necessarily less complexity. Drive-by-wire systems can be expensive to design and test, but they generally have a comparable, or even lower, parts cost vs. mechanical linkages. In addition, installation is often easier with drive-by- wire components compared to hydraulic systems. Many initial applications of drive-by-wire technology are occurring in off-highway vehicles, such as farm tractors. Drive-by-wire technology affects traditional wire harnesses, s more hydraulic hoses are replaced with electric wires, more harnesses will probably be required. Many automotive engineers are reluctant to adopt 100 percent drive-by-wire technology without redundant backups, including mechanical linkages.
