Intelligent Adaptive Cruise Control

Innovation: Intelligent Adaptive Cruise Control

Future driver assistant and autonomous driving systems need to be able to foresee the actions of other drivers.
At HRI-EU we have applied our prediction research to an intelligent Adaptive Cruise Control (i-ACC) system that can predict a lane change of a neighbouring car without the need to sense any lateral movement. Since 2015 this technology is commercially available in the European CR-V as part of Honda Sensing™, offering the world-first assistance beyond sensing.

i-ACC has been developed in cooperation with Honda R&D Inc. Japan and Honda R&D Europe (Deutschland) GmbH

The Technology of Honda i-ACC

The intelligent Adaptive Cruise Control (i-ACC) system uses a sensor fusion of milliwave radar and camera for accurate vehicle detection and localization. Additionally, lane markers are extracted from camera images.

To predict the future behavior of vehicles on the neighboring lane, i-ACC sets each vehicle in relation to up to five other vehicles in its vicinity.

Two different prediction methods are combined: a context-based prediction and a physical prediction. The two-stage process allows very early and very robust prediction. Both stages are combined with a smooth control process to maximize both safety and comfort for the driver. For early prediction the ego vehicle only brakes slightly, similar to releasing the gas pedal. As soon as the prediction is robustly validated, the ego vehicle applies the brakes as necessary to keep a safe distance.
