The Automated Halt Maneuvering (AHM) function is an advanced driver assistance feature that supports the bus driver in approaching a bus stop accurately and safely. When the driver decides to make a stop, they activate the system via the HMI. From that moment on, AHM takes over the preparation of the halting manoeuvre. The indicator lights are automatically switched on, and the HMI displays that the automated halting process has started. The driver remains responsible for the vehicle and must keep their hands on the steering wheel while reducing speed. Once the bus drops below 15 km/h, AHM automatically engages and begins steering, braking, and accelerating towards the bus stop.

The system recognizes the bus stop using map information and sensor data. All stops are pre‑mapped, including the exact boarding marker that defines the required stopping position. During the maneuver, AHM continuously determines the bus’s position relative to the platform and guides the vehicle along the edge with high precision. The bus must ultimately come to a stop within a total of 5 cm from the platform (2 cm at the front door) and exactly at the designated stopping point. This ensures a comfortable and safe boarding experience for all passengers, including wheelchair users and people with strollers.

Although AHM performs the maneuver, the driver (safety driver) remains fully responsible. They must be able to intervene at any moment by steering, braking, or accelerating. In such cases, AHM is immediately deactivated. In the event of system errors or loss of sensor data, the bus automatically comes to a stop and the driver is informed via the HMI that they must take over control. Once the bus has come to a standstill at the correct position, AHM is switches off. The driver can then open the doors to allow passengers to board and alight. After closing the doors, the driver (safety driver) drives away manually; AHM only becomes active again when the driver re‑activates it via the HMI.
