Power steering is a system for reducing a driver's effort to turn a steering wheel of a motor vehicle, by using a power source to assist steering. [1]Hydraulic or electric actuators add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds, and considerably reduce the physical effort necessary to turn the ...
Steer-by-wire, in the context of the automotive industry, is a technology or system that allows steering some or all of a vehicle's wheels without a steering column that turns the direction of those wheels mechanically. It is different from electric power steering or power-assist, as those systems still rely on the steering column to transfer ...
Dynamic steering response (DSR) is a vehicle safety and advanced power steering system that can counteract unstable or difficult steering that may be caused by external forces such as strong crosswinds or uneven roads by giving proper steering assistance from the steering gear. [1] DSR assists the driver by determining the correct steering ...
Active steering describes a steering system for a vehicle in which the relationship between the driver’s steer inputs and the angle of the steered road wheels may be continuously and intelligently altered. Whilst active steering systems may be found in agricultural equipment and heavy plant, this article concentrates on the application of ...
Drive by wire or DbW technology in the automotive industry is the use of electronic or electro-mechanical systems in place of mechanical linkages that control driving functions. The concept is similar to fly-by-wire in the aviation industry. [2] Drive-by-wire may refer to just the propulsion of the vehicle through electronic throttle control ...
The PID algorithm adjusts the engine’s power output to restore the vehicle to the desired speed, doing so with minimal delay and overshoot. The theoretical foundation and practical implementation of PID controllers originated in the early 1920s with the development of automatic steering systems for ships.
DIRAVI is the name given by Citroën to its proprietary power steering system, first seen in 1970. DIRAVI is an acronym for " Direction à rappel asservi " literally meaning "steering with controlled return" more accurately described in English as "power steering with power assisted return". [1] In the UK, it was marketed as VariPower and in ...
