In this blog post, we’ll examine the advancements in vehicle dynamics control technology and explore how advanced driver-assistance systems are helping to reduce traffic accidents.
The history of the automobile truly began with the development of the internal combustion engine. In 1860, Étienne Renoir of France developed a functional internal combustion engine, and in 1876, Nikolaus Otto of Germany completed the four-stroke cycle engine. Subsequently, in 1885, Germany’s Gottlieb Daimler and Karl Benz developed early forms of a two-wheeled vehicle and a three-wheeled automobile, respectively, and in 1913, Ford in the United States introduced the conveyor belt system to automobile production lines, marking the beginning of the era of mass-produced automobiles. Currently, the number of registered vehicles worldwide continues to rise, and South Korea is also among the countries with a very high vehicle ownership rate. As such, the automobile has become an indispensable means of transportation in modern daily life.
As automobiles became widespread, they enabled people to travel long distances in a short amount of time and are regarded as one of humanity’s greatest inventions. However, this has also led to problems—namely, traffic accidents. With the increase in automobile sales and the number of vehicles on the road, traffic accidents have become a major social issue worldwide, and various technologies are being developed to reduce them.
As technology advances, various efforts are being made to reduce traffic accidents—the biggest problem associated with automobiles. A prime example is technology that prevents accidents by dynamically analyzing a vehicle’s motion and controlling it accordingly. Simply put, this method involves analyzing the laws of motion of a vehicle and then having a computer use electrical signals to control the accelerator pedal, brakes, steering system, and wheels. However, to control a vehicle, it is first necessary to accurately recognize dangerous situations. Various sensors are most commonly used for this purpose. To draw an analogy with the human body, sensors act as the eyes, the computer acts as the brain, and the accelerator, brakes, steering system, and wheels function as the arms and legs. This basic structure, combined with various technologies, enables safe driving.
The first example is the emergency braking system. As the name suggests, this system controls the braking mechanism. While driving, the vehicle continuously detects its surroundings—such as the car ahead, pedestrians, and obstacles—through sensors. If it determines a dangerous situation, it alerts the driver and, if necessary, automatically slows down or stops the vehicle. This feature is highly effective in preventing rear-end collisions caused by the car ahead braking suddenly or other unexpected situations.
The second example is the adaptive cruise control system, which maintains a safe distance from the vehicle ahead. This system uses sensors to continuously measure the distance to the vehicle ahead and automatically accelerates or decelerates to maintain a consistent interval. Many of the latest systems also include a lane-centering feature. Especially on congested highways or city streets, where drivers must repeatedly operate the accelerator and brakes, fatigue can easily set in; these systems significantly reduce the burden on the driver.
The third example is the parking steering assist system. Here, “steering” refers to the operation of the vehicle’s steering wheel. Today, many vehicles assist drivers with parking using rearview cameras and parking sensors, and the parking steering assist system is an advanced version of these features. This system recognizes parking spaces, surrounding vehicles, poles, and obstacles to automatically control the steering mechanism and assist with parking. While major accidents resulting in loss of life are rare during parking maneuvers, this system can effectively prevent collisions between vehicles or contact with structures in environments where drivers lack experience or where parking spaces are narrow.
As shown here, various systems that make vehicles smarter are already being implemented in many cars today. Recently released vehicles are equipped with various advanced driver-assistance systems, such as emergency braking systems, adaptive cruise control, lane-keeping assist, and parking assist; in some environments, they even offer a certain level of autonomous driving capability. Global automakers, including Hyundai Motor Company, Mercedes-Benz, and Volkswagen, are continuously advancing these vehicle motion control technologies and continuing to invest heavily in research and development to create a safer and more convenient driving environment.
In conclusion, advancements in Hyundai Motor Company’s advanced safety features and driver-assistance systems have enabled a wide range of vehicle driving controls. Multiple automakers are continuously investing in technological development, and the ultimate goal of these driving technologies is the realization of a fully autonomous driving system. Autonomous driving systems—in which vehicles independently perceive their surroundings and safely navigate to their destinations without driver intervention—are realized through the integration of various sensors, vehicle motion control technologies, satellite navigation systems, and artificial intelligence. Although challenges remain to be addressed, if these technologies continue to advance and become commercialized, there is a strong possibility that an era of dramatically reduced traffic accidents and casualties will become a reality.
