Webasto has integrated a total of 25 sensors from Bosch, together with multiple additional functions, into the roof of a joint technology demonstrator. The vehicle will be unveiled to the public for the first time at Plug and Play’s EXPO2022 Startup Autobahn innovation platform on 7 July in Stuttgart. Four radar sensors, four lidar sensors and 16 cameras of various types from Bosch are integrated into the Roof Sensor Module from Webasto. The sensors reliably monitor the vehicle’s surroundings with the aim of enabling level 4 autonomous driving in future. In order to ensure functionality under all weather conditions, Webasto integrates cleaning, de-icing, anti-fog and sensor cooling functions, among others. Furthermore, a Bosch vehicle motion and position sensor, which uses Safe GNSS receivers for navigation satellite data\\ and accelerometers intertial sensors to determine abolsute and relative vehicle positioning. Creating an accurate picture of the surroundings requires an optimal sensor set combination. Radar sensors are important for measuring distances, speeds and contours, especially in bad weather conditions. Lidar provides a highly accurate three-dimensional picture of the surroundings and objects, while also detecting motions and measuring speeds. The use of different cameras enables not only distance, surroundings and objects to be detected and classified, but also facilitates the recognition of road markings, signs and traffic lights. Webasto combines and integrates the desired type and number of sensors into the Roof Sensor Module. This allows Webasto to achieve large-scale automotive industrialization, thereby offering its customers elegant solutions for automated (level 2) to fully autonomous driving (level 4). Openable roof systems, solar technology, ambient lighting and switchable glazing are examples of features that can be added to maximize customer benefits and comfort.
