New Concept of a Compact Lidar Scanner for ACC and Safety Applications

This contribution deals with the development of a new scanning time-of-flight Lidar device for automotive use. Originally designed for safety applications, it provides a horizontal field of view of up to 170°. The Lidar-inherent good lateral resolution allows for easy identification of position, width and outline of objects and obstacles in a traffic environment. A detection range of up to 170 m enables tasks such as Full Speed Range ACC (FSRA), thanks to its technology based on a production proven IDIS^® 1.0 circuit with Multibeam Lidar. A brushless DC Motor and a small momentum of inertia ensure the precision and sturdiness required for automotive applications. Therefore the new device represents a versatile, robust, and compact sensor concept at reasonable costs.
