Application of wire control technology on board aircraft
Xcar technology original
With the development of science and technology, and the increasing number of technologies transplanted to cars from the aviation sector, which, despite two issues of presentation, are just the tip of the iceberg, we will, in the current period, analyse the recent hotter cable-control technology and see what revolution it will bring to cars。
I. What's the cline control technology
Wire-controlled technology (by-wire) is commonly used to transfer to control by “wire” or telecommunications, rather than by “hard” connections to mechanical connectors。
Ii. The application of cline control technology on air
On board, line-control technology is the first one to be used to effect a linear shift technology for aircraft control, based on a system that transforms the pilot's manipulative signal into a telecommunications code and transmits it directly through a cable to an autonomous rudder. It removes the traditional aircraft-manufacturing system, which fills the aircraft with mechanical transmissions and hydraulic piping lines between the lever and the wheel. The main components of the tele-manufacturing system include motion sensors, central computers, actuators and power sources, which are equivalent to human sensory organs, brain and muscle。
Prior to 1964, the aircraft were carried with a shift of mechanical manipulative systems (the earliest of which was a zipping pattern, followed by hydraulic aids). The mechanical manipulation system has a rather complex set of mechanical connections and hydraulic pipelines between the manipulator (manipulation poles, feet) and the aircraft's rudders. Pilots control the rudder position through the above-mentioned rudders, thus enabling the aircraft to reach the desired posture and course。
With the increase in aircraft size and performance, increased stability has become increasingly urgent to help pilot manoeuvres, and the use of electro-gyroscope principles has led to the addition of stabilization systems, such as the optimisation and stabilization systems, the overhead and roll-on stabilization systems, based on hydraulic-aided control systems. The system automatically controls the rotation of the rudder under the control of the procedure in order to guarantee the flight characterization of the aircraft through the aircraft's state of sensor feedback。
After a short period of time, the operation was wired by way of a clutch or other method that separated the mechanical system when it was not in use, from which the aircraft completely departed from the mechanical movement. The first aircraft with a cable operating system was the united states military f111 “dolphin” fighter jet, which was tested for flight in 1964. Currently, civil aviation passenger aircraft, with the exception of military aircraft, have largely gained access to line control and technology, starting with airbus a320。
Line control in 2 cars
In fact, cable control is itself very close to our lives, except for the remote control vehicles mentioned above, and remote television, air conditioning, cooking equipment, even door locks. In cars, there are also a variety of wire-control techniques, such as video and audio control of cars, automatic air conditioning, electric control mirrors, seats, brushes, electronic stabilization systems, etc. Control systems such as electronic gas doors, electronic transformers, etc。
Although line-control technology is readily available, it is still rare to do so, as in the case of aircraft, to subvert traditional line-control conversion technology. We know that a shift system is like an aircraft operating pole, that early wire control technology is designed to optimize the operationality of the aircraft's rudders, and that as a vehicle's “both legs” shift system, can wire control be used? Mercedes-benz gave the first answer。
Apart from the first vehicle, the f200 super-contol vehicle, published by benz in 1996, the core of the line-control technology proposed on f200 is the removal of equipment such as steering wheel, shifting columns, oil doors, brake pedals and brakes, all of which are transmitted through a telecommunications signal through which the driver exercises control over the vehicle through the manoeuvring poles installed on the inside of the door and at the central control table, the driver does not have any hard-link structural conductor. As we have seen, such designs seem to be too empty and too subversive for traditional driving practices. So far, only a small proportion of the technology has been transplanted to the mass-producing model, and the core line-control shift technology has not resulted in volume production。
However, the mercedes f200 concept car, which was released 20 years ago, provided a good example of how many manufacturers later developed cable-control technology, but the f200 concept car does not seem to have a single mass-production model, so it is quite difficult, in the context of the existing car society, for such vehicles to be fully wire-controlled。
So, does the application of wire-control technology end? Today, nearly 20 years later, infiniti gave another answer。
The direct active steering (das) system carried by the infinidi q50 is derived from the cable-control switch technology on board the aircraft, which is the bulk-made model of the first-carrying technology, the greatest feature of which is the subversion of over 100 years of auto mechanics. It also bodes well for the auto-driving age。
The principle of the line control active transfer (das) system carried by the infinidi q50 system is that three sets of ecu computers transmit signals to three sets of electric motors on the basis of the steering wheel, with two sets of electrics controlling the wheel's rotation angle and speed, one set of electric machines to simulate feedback on the road, and a set of mechanical structures to be used as backup in the event of a malfunction in each of the three clusters. The signal is sent to the motor, which controls the switch to the pole to achieve the shift。
In the past, we have reported extensively on infinidi q50 and its das wiring system, which can be reviewed in the following terms:
Edition point evaluation: the aircraft applied cable control technology in order to improve the aircraft's accuracy and stability. Applications in the area of automobiles also value the advantages of this technology. After decades of development, although cable-controlled technology has been widely applied and disseminated in the area of automobiles, it is still in the “scrambling” phase of driving and driving cars。
At present, in the passenger market, only the infinidi q50l type carries the wire-control switch system, but we believe it is only temporary. As in the case of aircraft, there will soon be more types of line-control technology, which will be carried deeper into the vehicle and become more widely available。
