Mono camera offers advanced object detection

October 16, 2014 // By Christoph Hammerschmidt
Cameras for use in driver assistance systems are more than just an image sensor, combined with a basic data processing unit - they need to offer much more intelligence to offload the driver assistance. The S-Cam4 family that TRW Automotive has announced will go one step further: it will have an expanded object detection range and field of view that meet the increasingly stringent regulatory requirements for safety-relevant systems.

The S-Cam4 family includes a single lens, mono-camera version based on a standard housing and mechanical package designed to help meet test protocols such as pedestrian triggered automatic emergency braking (AEB) and new potential requirements including a crossing bicycle AEB test. The camera family also includes a premium three lens TriCam4 version to support advanced semi-automated driving functions.

Scheduled to launch in 2018, the next-generation single lens unit builds on the proven S-Cam3 mono camera, while the three lens camera adds a telephoto lens for improved long distance sensing, and a fish-eye lens for improved short range sensing ideal for semi-automated driving functions such Highway Driving Assist and Traffic Jam Assist. The S-Cam4 family will be equipped with Mobileye's Eye Q4 image processor and object recognition algorithms together with TRW’s longitudinal and lateral control algorithms to further enhance performance in premium DAS and semi-automated applications.

Advanced packaging includes an integrated processor and imager in a size similar to a deck of playing cards. TRW also utilizes a magnesium housing that yields excellent thermal properties resulting in better heat dissipation.
