In the second Industrial Revolution, two major means of transportation were born: the airplane and the automobile. The improvement of transportation efficiency has greatly expanded the circle of human life.

Aircraft has always been the carrier of various high-tech, its standard and advanced degree are ahead of the car. But with the continuous development of technology, a lot of aviation technology has begun to spread to cars, making our driving easier and safer. Don't believe it, these technologies, in fact, originated from aviation.

ABS anti-lock braking system

Initially, aircraft braking distances were very long during landing, and the braking process was easy to cause a flat tire due to tire locking. To this end, French aircraft designer Chabriere Voisin designed a set of wheel pulse braking system, which greatly reduces the braking distance and reduces the puncture, which is the prototype of the ABS anti-lock braking system.

Due to the continuous optimization of the electronic system, the traditional mechanical anti-lock braking system has been replaced by electronically controlled ABS. In the 1970s, this technology was first applied to automobiles, and with the maturity of technology and the continuous reduction of cost, ABS anti-lock braking system began to be widely popularized in the 1980s. In the case of emergency braking, the ABS anti-lock system can keep the front wheel steering function, improving the safety of the car.

At present, ABS anti-lock braking system has almost become the standard on the car, only strange models such as KTMX-BOW will ignore this configuration.

steering-by-wire

The term "steerable by wire" sounds like science fiction, but in fact its working principle has been widely used in the field of aviation. Due to the continuous development of aircraft, the traditional mechanical hydraulic transmission structure is complex, transmission speed is not agile enough, it is difficult to meet the demand; The wire transmission control technology has fast response, agile control and simple structure, which just makes up for the shortage of mechanical transmission. The principle of wire control is to let the control instructions be transmitted to the actuator by electrical signal after processing by the computer, so as to achieve control.

In the automotive field, the most representative of this black technology is the Infiniti Q50. It is equipped with "DAS wire control active steering" is also the principle: there is no hard connection between the steering wheel and the wheel steering machine, through three sets of independent electronic control units, comprehensive calculation of road conditions and the driver's operation intention, and finally through the cable control steering motor to complete the steering.

This steering system is much more responsive than traditional mechanical steering, and it also leaves more possibilities for future autonomous driving.

Teletype brake

Like steering-by-wire, fly-by-wire braking is derived from the aircraft's drive-by-wire technology. The advantages of its simple structure and rapid response are first applied to the pursuit of ultra-lightweight F1 cars: when the driver presses the brake pedal, the ECU controls the distribution of rear axle electric brakes and front axle mechanical brakes through calculation, thus simulating a linear braking effect. Provides the most powerful brakes without locking, and maximizes energy recovery.

In the last two years, this technology has gradually been applied to production cars, such as Alfa Romeo & Co. Giulia and new generation CR-V. The traditional hydraulic power brake needs to rely on the vacuum negative pressure generated by the engine to generate power, and the teletype brake is to complete the power by the motor, and only the brake part depends on the hydraulic system to complete.

It is worth mentioning that the brake of the hybrid model needs to be combined with the kinetic energy recovery system, so most of the hybrid cars including the Camry twin are using the fly-by-wire brake.

turbocharging

Due to objective conditions such as emission regulations and emission taxes, small-displacement turbocharged engines are becoming more and more popular in the market. When it comes to the origin of turbocharging, the most applied technology is the aircraft. Early propeller aircraft used naturally aspirated piston engines, but due to the thin air and low oxygen content of the aircraft in the high air, resulting in serious power decline, the addition of turbochargers just solved this pain point.

In World War II, turbo-powered fighters were equipped with excellent power and climbing performance. In the 21st century, most aircraft use turbofans and turbojet engines, although they abandon traditional turbochargers, they still charge air in the form of turbines.

When it comes to the application of turbochargers in automobiles, we have to mention the brand Saab. In the late 1970s, Saab began to promote turbocharging on a wide range of cars, and won the title of "flying close to the ground".

In recent years, the popularity of turbocharging, on the one hand, the use of turbocharged cars than the same displacement model more powerful, higher fuel efficiency, on the other hand, small displacement turbocharging in response to emissions regulations and emissions tax has more advantages.

HUD head-up display

Friends who have an understanding of the military know that the HUD head-up display on the fighter jet can facilitate the pilot to read the corresponding information, and can quickly lock the enemy aircraft in battle and attack faster.

The working principle of HUD is not complicated, through optical reflection, some important data is projected onto the glass screen, and the focal length of the reflection is adjusted to infinity, and the display effect can be achieved.
