Volvo Driver Alert Control and Lane Departure Warning
Volvo takes care of you when you want to sleep at the wheel. Two new safety systems will equip the next Volvo cars: Driver Alert Control and Lane Departure Warning . Driver Alert Control is a technology that alerts tired and unconcentrated drivers. Lane Departure Warning alerts the driver if the car cross one of the road markings without an obvious reason.

Volvo Cars introduces new systems for alerting tired and unconcentrated drivers
- Driver Alert Control - unique technology that alerts tired and unconcentrated drivers
Lane Departure Warning - alerts the driver if the car cross one of the road markings without an obvious reason.
Studies show that up to 90 percent of all traffic accidents are caud by driver distraction.
Now Volvo Cars introduces Driver Alert Control - with a technology solution that is a world-first in pasnger cars. The system aims to alert the driver when his or her concentration level is affected, for instance during long journeys.
Another new system, Lane Departure Warning, alerts the driver if the car cross one of the road markings without an obvious reason. 约翰库提斯
Lane Departure Warning and Driver Alert Control will be part of the same option package, called Driver Alert System. It will be available in the Volvo S80, V70 and XC70 at the end of 2007.

Lane Departure Warning
| 手机清内存 The Mobileye® lane departure warning application has been launched in multiple production platforms through 2007 and 2008 with GM, BMW and Volvo. Mobileye's lane departure and vehicle detection technologies are also included in Delphi's Advanced Collision Mitigation Systems which includes Delphi's Forewarn® Smart Crui Control with Stop and Go, Forward Collision Warning and Lane Departure Warning. 女人的照片View related press releas on Delphi's collision mitigation system, Mobileye's LDW technology in GM's 2008 破天荒Cadillac STS and Buick Lucerne Sedan, BMW's advanced lane departure warning and Volvo Car's new lane departure warning system. |

Lane Departure Warning (LDW) is available either as a standalone feature or as part of a wider functions bundle, such as LDW with Intelligent Highbeam Control and Traffic Sign Recognition on the BMW 7 Series or as a radar vision fusion system on the Volvo vehicles. From 2010 onwards Mobileye will launch LDW as part of wider functions bundles, such as LDW with Forward Collision Warning, Intelligent Highbeam Control, Traffic Sign Recognition and fusion to radar, for multiple other global vehicle makers on multiple vehicle platforms.
Mobileye us Lane Marking Detection and road geometry calculations to provide the driver with various functions such as Lane Departure Warning and Lane Keeping Support, which also us a fusion to the vehicle steering system. Lane Departure Warning gives the driver audio and visual alerts in ca of an unintentional lane departure, such as drifting out of lane or when not using the turn signals, whilst Lane Kee
ping Support will interact with the steering to provide a light feedback to alert the driver. The systems function in all light and weather conditions, though can be affected by extreme conditions, and detect all lane marking and road edge types.
Lane Departure Warning (LDW) / Lane Detection Algorithm (LDA)
The LDA recognis the lane markings and road edges and estimates the position of the car within the lane. The LDW module us this information on the basis of a Time to Lane Crossing calculation to provide a warning to the driver in ca of unintentional lane departure. The warning mechanism can be tuned for nsitivity – for example, the system can warn only when the vehicle is actually crossing the lane marking or it can give an early warning. The warning can be adapted to the type of road – for example it could provide the driver with more slack in ca of narrow roads or allow the driver to “cut” curves. In Lane Keeping Support (LKaS) the LDA is fud to the steering system, usually Electrically powered Steering systems, to provide a light haptic feedback (torque input) to the steering wheel to warn the driver of the situation.

Given that lane markings are visible and that their detection is not hindered by the prence of clutter, shadows, rain, snow or any other disturbance on the road, the LDA recognis the majority of white and yellow lane markings worldwide and the Mobileye system is over 99% available (as tested by vehicle makers in ries programs)
Various lane marking types, such as solid, dashed, Bott’s dots and double lane markings have been validated successfully and brought into production. Additionally the LDA recognis unmarked road edges such as the grass or gravel road edge. Additional information about the next lane is provided in order to aid the warning strategy and fine-tune it according to the OEM requirements. Moreover an approval mechanism for better paration of ambiguous lane marks, double lane marks, triple lane marks etc has been developed as well as fine tuning of the system to correctly react to the variability that exists in various countries. The approval mechanism can also make u of colour information (e.g. yellow lane marks) for better paration.
The LDA has been extensively tested in ries production programs in Europe, North America, South Africa, the Middle East and Asia, and has been validated globally on multi
ple continents and in a wide catalogue of scenarios, including bright sun and inclement weather. In construction areas, where there are multiple overlaid markings, the system becomes unavailable. Lane markings of different colours (ie Korean blue markings) may need special attention though preliminary testing has shown a favourable respon.
Mobileye is currently working on a rear facing LDA using the existing rear facing cameras already in production for reversing applications. This enhances LDW capability in more challenging scenarios, such as when entering a tunnel or assisting when for example the sun blinds front camera, reflections on road due to tar ams etc) and will improve overall system performance.
