GM engineers have made used of technology to help evaluate and enhance driver visibility in the Cadillac ATS luxury sports sedan. Use of new sight lines and visibility metrics developed considering factors like seat height, exterior mirror, forward vision distance, A-pillar area size and side vision distance have helped to enhance driving visibility and make travelling safer for those using demanding road transport networks.
Visibility for the ATS is greatly influenced by factors like design, aerodynamics and structural design which can pose quite a few challenges for those driving. ATS visibility has been evaluated by making use of a technique known as 'the Hedgehog'. The technique quickly characterizes 3-D aspects of A-pillar sight lines to understand how changes in windshield affect driver visibility in a tested driving scenario. Using data gathered, ATS designers made sure that they incorporated aspects that helped enhance forward driver visibility as compared to other vehicles. Rear vision camera with dynamic guidelines have helped to improve visibility of objects directly behind the Cadillac ATS. Advanced technologies making use of ultrasonic sensors, radar and cameras will help boost alertness and vision to road hazards thereby preventing accidents and providing a safe journey. Apart from enhanced driving technology, use of high grade lightweight materials help to boost structural integrity and improve fuel efficiency of the ATS.
