- Today, as the spread of vehicles equipped with autonomous driving functions increases, accidents caused by autonomous vehicles are also increasing. Autonomous vehicles are robotic systems and include three main functions of sensing, planning, and acting. Therefore, accidents can occur due to perception errors, judgment errors, and action errors. Since the fatal accident caused by an autonomous vehicle in 2016, fatal accidents have occurred continuously, and in March 2018, an accident that caused the death of a pedestrian occurred. Therefore, issues regarding safety and reliability of autonomous vehicles are emerging. Various studies have been conducted to secure the safety and reliability of autonomous vehicles, and the application of the international standard ISO 26262 for safety and reliability improvement and the importance of verifying the safety of autonomous vehicles are increasing. Recently, Mobileye proposed RSS model called Responsibility Sensitive Safety. The RSS model is a mathematical model that presents the standardization of safety guarantees of the minimum requirements that all autonomous vehicles must meet. Autonomous vehicles use various sensors such as cameras, radar, and lidar to perception objects. If a heterogeneous sensor is used, a separate processor for each sensor is required, complicating the system configuration, and this increases the possibility of system errors. Therefore, by using a variable focus function camera, the coverage area of existing radar or lidar can be covered with a single camera, and overcome disadvantages caused by using heterogeneous sensors. In this paper, the RSS model that ensures safety and reliability was derived to be suitable for variable focus function cameras that can cover the cognitive regions of radar and lidar with a single camera.
