ZF has developed a dual-cam two-lens camera specifically for the commercial truck market. The camera is designed to be used with other ZF ADAS technologies.
Part of ZF's S-Cam4 family of automotive grade cameras, the dual-cam was developed to help meet varying global regulatory requirements. It delivers such functions as traffic sign recognition, lane keeping assist and centering, and object and pedestrian detection to enable automatic emergency braking (AEB).
"To help ensure these technologies work effectively on commercial trucks, a second lens is necessary for some of these advanced functions," said Dan Williams, Head of ADAS and Autonomy for ZF Commercial truck applications. "For example, for pedestrian AEB, in some instances a standard mono-camera with a 52-degree field can limit the ability to detect pedestrians or other vulnerable road users with enough time to actuate the brakes and help avoid or mitigate accidents for larger trucks in complex environments."
Having a second lens also enables redundancy for Level 2+ functions. If one lens becomes blinded or non-functional, the second lens helps ensure that the camera can still operate due to multiple optical paths.
When combined with a full suite of the company's ADAS technologies such as forward looking and corner radar, automated functions such as lane change assist and traffic jam assist are enabled. These functions can form the basis for technologies such as truck platooning.
