A steering control system (100) for a commercial vehicle (10) ist disclosed. The commercial vehicle (10) comprising a braking system (20) and a steering system (30), the braking system (20) being configured to brake dissymetrically side wheels of the vehicle (10), the steering system being configured to steer the vehicle (10) in response to a steering signal (112, 113). The steering control system (100) comprises: a selection module (110) and a control module (120). The selection module is configured to switch between a first steering mode and a second steering mode, wherein the first steering mode indicates a steering of the vehicle (10) by turning vehicle wheels and the second steering mode indicates a steering of the vehicle (10) by generating a braking signal for at least one vehicle wheel resulting in a yaw moment applied to the vehicle (10). The control module (120) is configured to generate the first steering signal (111) indicating a steering demand in the first steering mode and a second steering signal (112) indicating a steering demand in the second steering mode. The control module (120) is further configured to provide the first steering signal (111) to the steering system (30) and the second steering signal (112) to the braking system (20) to brake the vehicle (10) dissymetrically and thereby steer the vehicle (10) as a result of the yaw moment.

Disclosed is a safety system (100) for a vehicle combination (50) with a towing vehicle (52) and a trailer (55), wherein the towing vehicle (52) comprises a plurality of sensors (510) configured to provide sensor data about an environment of the towing vehicle (52) or a state of the towing vehicle (52). The safety system (100) comprises a data collection module (110) for collecting the sensor data; an extraction module (120) for extracting, from the sensor data, information about a presence of the trailer (55) or about a state of the trailer (55); a control module (130), configured to control, based on the extracted information, at least one driving task or to provide the information to another component of the towing vehicle (52) in order to increase the safety of the vehicle combination (50).
