By-wire
By-wire refers to technologies in which a system is controlled using electrical or electronic means rather than by a mechanical linkage that transfers force from the input to the system. The concept is used in aviation and in the automotive industry. By analogy, it may refer to managing by wire, a management style relying on an informational representations of the business, similar to fly-by-wire pilots who rely on an informational representation of the plane. By-wire concepts and systems include: * Drive by wire in automotive contexts ** Accelerate-by-wire or throttle-by-wire, more commonly known as electronic throttle control ** Brake-by-wire ** Shift-by-wire in automatic transmissions that are manumatic or in automated manual transmissions. This may include park by wire which actuates the parking pawl as part of the shifting system. ** Steer-by-wire * Fly-by-wire Fly-by-wire (FBW) is a system that replaces the conventional aircraft flight control system#Hydro-mechanical, ...

Fly-by-wire
Fly-by-wire (FBW) is a system that replaces the conventional aircraft flight control system#Hydro-mechanical, manual flight controls of an aircraft with an electronic interface. The movements of flight controls are converted to electronic signals, and flight control computers determine how to move the actuators at each control surface to provide the ordered response. Implementations either use Aircraft flight control system, mechanical flight control backup systems or else are fully electronic.Fly by Wire Flight Control Systems Sutherland Improved fully fly-by-wire systems interpret the pilot's control inputs as a desired outcome and calculate the control surface positions required to achieve that outcome; this results in various combinations of rudder, Elevator (a ...

Drive By Wire
Drive by wire or DbW in the automotive industry is the technology that uses electronics or electro-mechanical systems in place of mechanical linkages to control driving functions. The concept is similar to fly-by-wire in the aviation industry. Drive-by-wire may refer to just the ground propulsion, propulsion of the vehicle through electronic throttle control, or it may refer to electronic control over propulsion as well as steering and braking, which separately are known as steer by wire and brake by wire, along with electronic control over other vehicle driving functions. Driver input is traditionally transferred to the motor, wheels, and brakes through a mechanical linkage attached to controls such as a steering wheel, car controls#Throttle control, throttle pedal, hydraulic brake pedal, parking brake#Pedal or pull handle, brake pull handle, and so on, which apply mechanical forces. In drive-by-wire systems, driver input does not directly adjust a mechanical linkage, instead th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brake-by-wire
Brake-by-wire technology in the automotive industry is the ability to control brakes through electronic means, without a mechanical connection that transfers force to the Brake#Types, physical braking system from a driver input apparatus such as a brake pedal, pedal or parking brake, lever. The three main types of brake-by-wire systems are: electronic parking brakes which have, since the turn of the 21st century, become more common; electro-hydraulic brakes (EHB) which can be implemented alongside legacy hydraulic brakes and as of 2020 have found small-scale usage in the automotive industry; and electro-mechanical brakes (EMB) that use no hydraulic fluid, which as of 2020 have yet to be successfully introduced in production vehicles. Electro-hydraulic braking systems control or boost the pressure applied to the hydraulic pumps through the brake pedal. Safety requires that the system remains fail-operational in the event of a power failure or an electronic software or hardware faul ...

Steer-by-wire
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 some steering torque to the wheels. It is often associated with other drive by wire technologies. A vehicle with a steer-by-wire system may be manually controlled by a driver through a steering wheel, a yoke, or any other controller which is connected to one or more electronic control units, which uses the input to control steering actuators that turn the wheels side-to-side, steering the vehicle. The steering wheel or yoke may be equipped with haptic feedback to simulate road feel and wheel resistance, and change depending on the vehicle speed or customizable settings. The safety of drive-by-wire systems is often ensured through redunda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Managing By Wire
Managing by wire is a management strategy in which managers rely on their company's "information representation" generated by computers such as databases and software instead of on detailed commands. It was presented by Stephan H. Haeckel and Richard L. Nolan in a 1993 ''Harvard Business Review'' article. The authors chose the term "managing by wire" as an analogue to the fly-by-wire concept for jets. SAP SE, Aetna, Mrs. Fields Cookies, and Brooklyn Union Gas have done "managing by wire". History The concept was presented in an article titled "Managing by Wire" in the September–October 1993 issue of ''Harvard Business Review'' by Stephan H. Haeckel and Richard L. Nolan. When they wrote the article, Haeckel was the director of strategic studies at IBM's Advanced Business Institute and Nolan was a professor at the Harvard Business School. In his 2003 book ''The New Ruthless Economy'', Simon Head called the article "an important milestone in the intellectual gestation of the corpo ...

Electronic Throttle Control
Electronic throttle control (ETC) is an Automotive engineering, automotive technology that uses electronics to replace the traditional mechanical linkages between the driver's input such as a Car controls#Throttle control, foot pedal to the vehicle's throttle mechanism which regulates speed or acceleration. This concept is often called drive by wire, and sometimes called accelerate-by-wire or throttle-by-wire. Operation A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM). The ECM is a type of electronic control unit (ECU), which is an embedded system that employs software to determine the required throttle position by calculations from data measured by other sensors, including the accelerato ...

Shift-by-wire
Shift-by-wire is an automotive concept or system that employs electrical or electronic connections that replace the mechanical connection between the driver's gearshift mechanism and the transmission. Since becoming commercially available in 1996, shift-by-wire has been commonly used in automated manual transmission and has later been implemented in semi-automatic transmission and automatic transmission. Dispensing with gearshift mechanical linkages has several advantages: it reduces complexity and simplifies assembly; reduces the force required to shift gears and allows it to be customized with haptic technology; allows for more interior design freedom in the placement of the gearshift mechanism; allows for automation of the engagement of the parking brake and other functions; reduces cabin noise by eliminating the acoustic linkage between the transmission and the gear shift; and by reducing floor openings it improves the crash behavior of the vehicle. With a mechanical connect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Linkage (mechanical)
A mechanical linkage is an assembly of systems connected so as to manage forces and Motion, movement. The movement of a body, or link, is studied using geometry so the link is considered to be Rigid body, rigid. The connections between links are modeled as providing ideal movement, pure rotation or Sliding (motion), sliding for example, and are called joints. A linkage modeled as a network of rigid links and ideal joints is called a kinematic chain. Linkages may be constructed from open chains, closed chains, or a combination of open and closed chains. Each link in a chain is connected by a joint to one or more other links. Thus, a kinematic chain can be modeled as a graph in which the links are paths and the joints are vertices, which is called a linkage graph. The movement of an ideal joint is generally associated with a subgroup of the group of Euclidean geometry, Euclidean displacements. The number of parameters in the subgroup is called the degree of freedom (mecha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
