Hyundai Motor Co. and Kia Motors Corp. said Tuesday that they have developed the world’s first forward-looking “ICT-connected shift system” that allows vehicles to identify road features and traffic conditions on their own and shift them to the optimum gear units accordingly. Hyundai and Kia plan to apply the technology to their new cars to come in the future.
Previously, the technology to automatically change shift mode according to driver’s propensity, such as “smart drive mode,” has mostly been applied to Hyundai-Kia models, but it is the first technology to automatically shift to suit road and traffic conditions like the “ICT-connected shift system.”
The “ICT-connected shift system” is powered by 3D navigation equipped with three-dimensional precision maps of the road, camera for smart cruise control and radar and other various ICT devices combined with intelligent software to control the transmission, and about 40 key patents were applied at home and abroad during the system development process.
The technology starts with collecting information through various devices, such as 3D navigation’s road height, curvature, type of road, and unexpected situations, the distance between vehicles on the forward radar and speed information on the relative vehicle, and the lane and visual information of the forward camera are sent to the TCU (Transmission Control Unit).
The TCU, which received the signals, predicts optimal shift scenarios for real-time driving situations through artificial intelligence algorithms, and appropriately changes the transmission’s gears according to the results. For example, if a relatively long inertial drive is expected, it improves fuel consumption efficiency (fuel economy) by placing the transmission in a transient neutral state.
When Hyundai and Kia tested vehicles with an “ICT-connected shift system” on a curved road, they found that the frequency of shifts in cornering was about 43 percent less than that of conventional vehicles, which also reduced the frequency of brake operation by about 11 percent, improving driving fatigue.
In addition, when it was necessary to make a sharp acceleration to enter the highway, driving mode was automatically switched to Sport mode from the location of joining the highway, making it easier to join the traffic flow on the highway, and after entering the highway, it was automatically returned to the original driving mode, enabling safe and efficient driving.
In addition, the engine brakes were automatically activated when the vehicle took its foot off the accelerator pedal after judging itself on the speed bump, downhill gradient and the location of changing the speed limit in front of the car, and the transmission was automatically adjusted by detecting the distance or distance from the car ahead.
In fact, Hyundai Kia Motors Namyang Institute, a trial run by headquarters to sail to Yangjae-dong, Seocho-gu, Seoul, Korea about frequency prediction ahead, as of 31 percent shift mode is activated while the unjeongam.Significantly improved effect.
The technology is also in line with the self-driving technology that is developing day by day. The “ICT Connected Shift System” can provide both improved fuel efficiency and a stable driving sense in the era of self-driving cars as it prepares vehicles in the optimum condition by identifying road conditions that drivers are not aware of in advance
Hyundai-Kia plans to develop its “ICT-connected shift system” into more intelligent transmission technologies, allowing it to communicate with traffic lights based on LTE or 5G communications, and identifying drivers’ tendencies and reflecting them in shift control.
“Automobile cars are evolving into smart mobility, not just mobile vehicles,” said Jeon Byung-wook, a researcher at Hyundai-Kia Automotive Industry Research Lab. “The traditional automotive sector like Powertrain is establishing itself as a cutting-edge technology optimized for smart mobility through efforts to incorporate ICT and artificial intelligence technologies.”
