Hyundai-Kia Develop Predictive Gear Selection Based on Data

Cutting edge cars are becoming more and more connected and now Hyundai and Kia are working on the next logical step: revolutionising the gearbox. Their latest development is to deliver predictive gear changes by linking the transmission control unit to other systems within or connected to the car through a network.

They are calling it the “ICT Connected Shift System” and the technology is aimed at reducing the number of unnecessary shifts and brake inputs. This has the effect of reducing driver fatigue and increasing fuel efficiency.

ICT Connected Shift uses 3D navigation, cameras, and radar to detect road and traffic conditions. The data is fed to software that uses Artificial Intelligence to determine what the gearbox should do. Not only will the system be able to shift up or down more optimally, but it will also be able to disengage the clutch when it is safe and ideal to do so. Future applications will see the system taking data from external, connected sources through 5G networks.

PRESS RELEASE

Hyundai Motor Company and Kia Motors Corporation announced today that they have developed the world’s first predictive Information and Communication Technology (ICT) Connected Shift System, enabling the vehicle to automatically shift to the optimal gear after identifying the road and traffic conditions ahead. Hyundai and Kia plan to apply the technology on future vehicles. During system development, the companies filed about 40 major patents in South Korea and abroad.

While the technologies used to automatically shift depend on drivers’ preferences, such as Smart Drive Mode – available on most current Hyundai and Kia models – ICT Connected Shift System is the first ICT to automatically shift the gear according to road and traffic conditions.

ICT Connected Shift System uses intelligent software in the Transmission Control Unit (TCU) that collects and interprets real-time input from underlying technologies, including 3D navigation equipped with a precise map of the road as well as cameras and radar for smart cruise control. The 3D navigation input includes elevation, gradient, curvature and a variety of road events as well as current traffic conditions. Radar detects the speed and distance between the vehicle and others, and a forward-looking camera provides lane information.

Using all of these inputs, the TCU predicts the optimal shift scenario for real-time driving situations through an artificial intelligence algorithm and shifts the gears accordingly. For example, when a relatively long slow down is expected and radar detects no speed irregularities with the car ahead, the transmission clutch temporarily switches to neutral mode to improve fuel efficiency.

When Hyundai and Kia tested a vehicle with an ICT Connected Shift System on a heavily curved road, the frequency of shifts in cornering was reduced by approximately 43 percent compared to vehicles without the system. Accordingly, the system also reduced the frequency of brake operation by approximately 11 percent, thereby minimizing driving fatigue and brake wear.

When rapid acceleration was required to enter a highway, the driving mode automatically switched to Sport Mode at the merge, making it easier to join the traffic flow. After merging with traffic, the vehicle automatically returned to its original driving mode, enabling safe and efficient driving.

In addition, the engine brakes were automatically applied upon release of the accelerator pedal by determining speed bumps, downhill slopes and location of the speed limit change on the road. The changes in distance from the front car were detected by the front radar to adjust appropriate transmission gear automatically, which improved driving quality.

The system is also in line with autonomous technology, which is developing day by day. The ICT Connected Shift System will deliver both improved fuel efficiency and a stable driving experience in the era of autonomous vehicles by providing improved performance in response to real-time road and traffic conditions.

Hyundai and Kia are planning to further develop the ICT Connected Shift System into an even more intelligent transmission technology that can communicate with traffic signals based on LTE or 5G communication and identify drivers’ tendencies, resulting in further refinement of gear-shift control.

“Vehicles are evolving beyond simple mobility devices into smart mobility solutions,” said Byeong Wook Jeon, Head of Intelligent Drivetrain Control Research Lab. “Even a traditional area of the automobile, such as the powertrain, is becoming a high-tech technology optimized for smart mobility through efforts to integrate ICT and artificial intelligence technologies.”
