Honda, going a step ahead of its contemporaries, is all set to introduce the world's predictive cruise control system known as Intelligent Adaptive Cruise Control (i-ACC). It is capable of foreseeing and automatically reacting to other vehicles ‘cutting-in’ to the equipped vehicle’s lane. i-ACC will make its debut this year on the new CR-V, building upon the traditional Adaptive Cruise Control (ACC) system.
Based on extensive real-world research of typical European driving styles, Honda’s Intelligent Adaptive Cruise Control (i-ACC) uses a camera and radar to sense the position of other vehicles on the road. It then applies an algorithm to predict the likelihood of vehicles in neighboring lanes, cutting-in by evaluating relations between multiple vehicles, enabling the equipped vehicle to react quickly, safely and comfortably. Dr. Kleinehagenbrock, responsible for i-ACC at Honda R&D Europe (Deutschland) GmbH says, ‘i-ACC takes cruise control systems to a whole new level, offering what we call ‘predictive safety’. Dr. Schmuedderich added, “i-ACC is a significant breakthrough and a considerable further step towards a new generation of driver assistance systems that anticipate the behavior of other traffic participants.”
The traditional ACC systems keep a preselected longitudinal velocity, which is only reduced for maintaining a safe distance to a car in front. However, if a vehicle cuts-in from a neighboring lane, the traditional ACC system reacts later thus requiring stronger braking. However, if a vehicle cuts-in from a neighboring lane, the traditional ACC system reacts later thus requiring stronger braking. On the other hand, the new i-ACC system is able to compute the likelihood of a cut-in up to five seconds before it occurs, and is therefore designed to react very smoothly so as not to startle the driver, who might not yet be aware of the imminent cut-in. In this case the system applies just a mild brake initially, with an icon appearing on the driver display, informing the driver why a slow-down occurs. It then proceeds to apply a stronger brake to adapt the velocity to keep a safe distance.
