The Roof Sensor Module: elegant and reliable sensor integration

Reliably recording the surroundings, detecting obstacles and hazards in any weather – camera, radar and lidar technologies offer the technical possibilities for this. For Webasto, integrating sensor technology elegantly into the car roof as the highest point of the vehicle is therefore the logical step and a perfect solution for the future of autonomous mobility. 

Our strength

Tailored sensor set

Depending on the customer's needs, we can combine the desired type and number of sensors in our RSM: Thus, we offer elegant solutions for automated (level 2) to fully autonomous driving (level 4). 

Elevated position

In the elevated position on the roof, the sensors optimally and reliably detects the vehicle’s surroundings.

Elegant design

Roof Sensor Module (RSM) integrates lidar and camera technologies, among other things, in a fully functional and elegant way into the roof system.

Versatile solutions

Roof Sensor Module

Retractable Lidar sensor

The world's first retractable Roof Sensor Module integrates lidar and sensor redundancy systems on the roof for improved aerodynamics and aesthetics. The integrated cleaning system, motion and drive mechanism and water management system, ensure sensor availability in all weather conditions.

Innovative solutions for trucks 

In the truck sector, there is a growing need for autonomous driving in order to keep pace with developments in supply chains. The requirements for sensor integration are extremely demanding: in addition to vibrations and environmental detection, the running time is also more challenging than for passenger cars. In order to meet these requirements, sensors of various types (camera, radar and lidar) are integrated. It is also crucial that the sensors work perfectly in all weather conditions. 

Webasto uses its expertise from the passenger car and robotaxi sectors, where sensor modules are already successfully used with innovative and automated cleaning and thermal management systems that clean, heat, cool or de-ice the sensors, depending on the weather conditions.

 

Due to other fields of activity, Webasto has expertise in the truck sector and is familiar with the demanding requirements. 

Webasto supports and further develops autonomous driving by enabling industrialized series production for sensor integration in trucks.  

Reliable dectection of the surrounding

Camera, radar and lidar technologies lay the foundation for safety and reliable 360° environment detection in autonomous driving. An accurate picture of the environment succeeds in the interaction of an optimal sensor set. Depending on requirements, the desired number of sensor types is combined and elegantly integrated into the Roof Sensor Module.

Radar senors

Distance, speed, contours

Radar sensors determine angles and the distance to objects, among other things, thanks to electromatic waves. They are therefore important for detecting distances, speeds and contours, especially in poor weather conditions.

Functions for sensor availability

In order to guarantee the functionality of the sensor system across all weather conditions and contamination levels, various cleaning systems, using water and air, are integrated into the Roof Sensor Module, as well as functions for de-icing and fog removal. The intelligent thermal management also ensures optimum operating conditions.

Sensor availability

Clear view

A major advantage of positioning the sensor system in the roof, in addition to optimum ambient detection, is less contamination. An innovative and automated cleaning system also plays a decisive role. Any type of soiling is detected, whereupon the automatic cleaning system is activated.

Sensor availability

Perfect operating conditions

The high-tech, complex sensor technology integrated in the Sensor Module requires optimal operating temperatures for reliable results. Even extreme temperatures, like heat or frost, are regulated and managed by an innovative thermal management system.
