Changes in steering system for self-driving cars
Changes in steering system for self-driving cars
Research and development of self-driving cars, which is known to have been researched and developed for about 100 years, or 50 years in short. In recent years, along with breakthroughs in camera, LiDar, radar and computer performance, and AI, the possibility of self-driving car technology has increased, and R&D has been conducted in earnest, and some practical applications such as market launch and service expansion are in progress It's done. As various self-driving technologies are developed, future growth potential is predicted to be high.
Autonomous driving technology is largely divided into six stages. This classification was subdivided and defined by the Society of Automotive Engineers (SAE International, hereinafter SAE), and is currently being used internationally. The higher the level, the less human intervention in driving.
From level 4 or higher, where drivers can be completely free, robotaxi, self-driving delivery service, unmanned shuttle bus, and self-driving logistics service will be available. The prospect of autonomous driving level 4 or level 5 is reported in various views, but according to Frost & Sullivan data, it is expected to occupy about 4% of the global automobile market in 2025 and about 15% in 2030.
Shall we look at the usefulness of self-driving cars? As a result of NHTSA (US Highway Traffic Safety Administration) research, 90% of current car accidents are caused by driver negligence, and if accidents can be prevented, economic savings of about 400 billion dollars are expected. In addition, utilization is expected to increase to 75% when usage behavior changes from the current private ownership of vehicles, where vehicle utilization is 5-10%, to the car-sharing model of autonomous vehicles. The degree of freedom of passengers is also increased. In self-driving cars, every passenger will be a passenger and will be able to enjoy various activities such as meetings, shopping, entertainment, and watching TV/movies while on the go.
However, there are still many problems that need to be addressed for fully autonomous driving. The self-driving system considers safety too conservatively and cannot make a left turn at a crossroads, a rear-end collision due to a sudden stop, entering the asphalt being paved and not being able to get out, or a collision by recognizing the white background of the front truck as the sky. Many incidents and accidents of often occur and are reported. For this reason, the pessimistic outlook on the timing and technological maturity of self-driving vehicles and services is at odds with the optimistic outlook described above.
Even in this situation, what is clear is that autonomous driving level 2 and even level 3 technologies have been developed and are rapidly being applied in the market. Even for level 4 functions, services are being launched under test operation or safe driver accompaniment within ODD (Operational Design Domain), an area where autonomous driving is used. It is expected to continue to expand throughout the region.
Along with the self-driving car trend described above, the mobility market is in a mega trend called ‘C.A.S.E (Connected, Autonomous, Shared, and Electric)’. Engineers who research and develop steering systems cannot help but think about new customer requirements and use cases in various driving environments amidst these trends. In this C.A.S.E trend change, the steering system requires high safety, securing occupant space, increasing comfort, various additional functions, and high-output systems.
Reflecting this, we developed new products such as SbW (Steer by Wire), RWS (Rear Wheel Steering), 4WIS (4 Wheel Independent Steer), and New HMI (Human Machine Interface), as well as multiple safety systems, high-voltage E/E systems, and autonomous driving control. Research on new technologies such as logic and integrated control technology is required.
Since 2012, HL Mando has utilized the electric/electronic system redundancy (E/E redundancy) technology developed for the purpose of preventing the risk of sudden loss of steering assistance that may occur in the event of a failure of the EPS system. Reviewed the development of a 'Pure Play' SbW system, a 'Signal Intelligent Steering System' concept. Since 2016, we have started developing ‘Steer by Wire (SbW)’ in earnest and are preparing for mass production. Every year, HL Mando held a Summer & Winter Ride Session event with vehicles equipped with SbW and IDB (Integral Integrated Electronic Brake) products for domestic and foreign customers.
In particular, SbW is evaluated as a technology that can overcome the limitations of conventional vehicle design and autonomous driving by eliminating physical connections. First of all, since there is no physical connection between the chassis and steering wheel, such as a steering clutch, the driver's seat position does not need to be fixed, which allows for a variety of vehicle body and interior space designs. It means that the interior space of the vehicle is wider and the space utilization is increased.
In addition, through the support of fully autonomous driving and ‘Quiet Mode’, which fixes the steering wheel in autonomous driving mode, occupant fatigue is prevented, and individual settings according to the variable gear ratio and driving mode are possible.
In addition to the automotive industry, the Halla Group carries out activities in many other areas. These include, for example, shipbuilding, education and sports.
One of the largest brands in the automotive supply industry is Mando Aftermarket, which is part of the South Korean Halla Corporation Europe.
This event was organized by one of the largest purchasing groups in the world called Nexus, with which we cooperate.
