Bosch Presents New Assistance System for Railway

The new assistance system rail forward assist from Bosch Engineering ensures greater safety in rail transportation and helps to further reduce the number of accidents. In urban areas, the company has offered a collision warning system for trams since 2017.

“With rail forward assists, we are now transferring the successful concept to the railway. The application areas of the collision warning system are local public transport, shunting operations, and track maintenance vehicles,” explains Heiko Mangold, head of rail technology at Bosch Engineering.

The modular assistance system consists of a control unit and various sensors, which ensure seamless monitoring of the area in front of the rail vehicle. The sensor cluster employed depends on the specific use case and can comprise camera, radar, LiDAR, and ultrasonic modules.

For metro, urban, -suburban, and regional trains, the mainline and urban forward assist system monitors not only the area in front of the rail vehicle but also the platform environment. The system warns of obstacles on the track as well as dangerous situations at rail stations. It also offers signal detection and a braking assist function.

Shunting operations are particularly challenging for rail personnel since, for their protection, they must remain aware of railway activity on parallel tracks while also carrying out their actual shunting tasks. Shunting forward assist supports shunting personnel by warning them of obstacles in the track area, such as incorrectly parked wagons and impending collisions due to incorrectly set switches.

The system also features coupling assist and signal detection functions as well as an overhead catenary assist for locomotives with hybrid powertrains. The resulting benefits include significant mental and psychological relief for personnel, increased safety, fewer personal injuries, less property damage, and prevention of costly overhead wire damage.

The system is based on a robust multisensor concept and is tailored to the specific requirements of the rail sector. It is also certified according to EN 50155 and EN 50128. The system’s modular design enables flexible use in different rail segments, both for customer-specific use cases and in special applications. Initial pilot projects for the surround sensing function in the rail sector have been implemented with great success.

“With our expertise and technologies, we want to play a key role in driving the complex automation of rail transportation. We are thus edging ever closer to the long-term vision of fully automated, highly connected, and thus more efficient and safer rail traffic,” added Mangold. Initial steps toward full automation are being made in low-speed applications. These include the automation of train preparation as well as fully automated shunting operations.
