Kia and Hyundai develop ICT shift system
Kia Motors and Hyundai Motor announced 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.
Kia and Hyundai 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 Kia and Hyundai 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.
When Kia and Hyundai 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 per cent compared to vehicles without the system. Accordingly, the system also reduced the frequency of brake operation by approximately 11 per cent, thereby minimising 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.
