A. Description of Available Systems and others combine the two braking functions. One special system is the so-called City Safety System, which also reacts to pedestrians, which is normally not the case for AEB systems. A.3. LDW, LKA and LKS Lane-Departure Warning (LDW) and Lane-Keeping Assistant (LKA) systems help the driver prevent unintentional lane departures. Thus, these systems are primarily safety- oriented system. However, there are systems available that focus on increasing the comfort as well. LDW systems warn drivers if they are about to depart from the lane without using the turn indicator. LKA systems also apply the brakes or apply steering torquetothesteeringcolumntosteer thevehicleback into its lane. Theabovementioned comfort-orientedsystemisonlypossible if the interventionisdoneviathevehiclesteering. This kind of system is called Lane-Keeping Support (LKS). A.4. LSF Low-Speed Following (LSF) systems control the vehicle in the longitudinal and lateral directions. They follow the proceeding vehicle at low speeds to support the driver in traffic jams. These systems can be seen as a combination of FSRA and LKS systems. A.5. PA Parking Assistant (PA) systems support the driver in parking the vehicle. There are different levels of PA systems available. The easiest one just provides acoustic or visual information about the distance between the vehicle and other objects. On the highest level available, systems park the vehicle semi-automatically. This means that the driver is still responsible forhisvehicle,butthevehicleperformsnearlyallactions(e.g. steering, acceleration and deceleration). The driver has to monitor the system intervene if the system is about to fail. A.6. BSM Blind-Spot Monitoring (BSM) systems warn the driver against collisions that may occur due to lane change manoeuvres. The system can be divided into two different functional- ities. Thefirstone ispureBSM,where the systemonlywarns if anotherobject isdriving in the blind spot of the vehicle and cannot be seen with the vehicle mirrors. The second onealsodetectsclosingvehicles thatapproachthedriver’svehicleveryquickly. Although 94
