CAN in driver assistance system

For the CAN-connectable Mobileye driver assistant system ST Microeletronics (France) has announced the third generation of an SoC processor. The vision-based driver assistant system developed by Mobileye (Israel) provides a redundant interface for the CAN in-vehicle networks.The EyeQ3 and EyeQ3-Lite will be the first members of a third-generation family in the co-operation, which began in 2005 between ST and Mobileye. The EyeQ1, the first generation of the processor, is now in production at several car makers and offers market-leading functions to drastically reduce the number of accidents, including lane-departure warning (LDW), adaptive-headlight control (AHC), traffic-sign recognition (TSR), collision avoidance via radar-camera fusion, and forward collision warning (FCW).For the award-winning second generation, ST and Mobileye increased the single-chip processing power of the EyeQ2 by six-fold over the EyeQ1, enabling the vision processor to take the active-safety concept to a new level, in recognition that pedestrians are the most vulnerable road users. In the USA alone, NHTSA (National Highway Traffic Safety Administration) reports that 4 000 fatalities and 60 000 injuries from road accidents involve vehicles colliding with either pedestrians or cyclists. Therefore, in addition to integrating extra Mobileye radar-vision fusion-based functions on top of those offered in the previous generation, the EyeQ2 features ‘pedestrian detection’ and an option for the car manufacturer to enable fully automatic emergency braking, particularly for use in urban environments. The EyeQ2 has recently entered into production in the new Volvo S60 sedan-car series with additional launches of EyeQ2-based systems expected in the coming months from several carmakers.
