Claim 10:
11. A driver-assistance-system-based steering system assistance for a transportation vehicle with a steering system for assisting a driver when steering the transportation vehicle, with a sensing and control unit to provide driver-assistance-system-based steering assistance wherein:
a driving situation of the transportation vehicle is sensed,
an intervention into the driving behavior of the transportation vehicle is carried out in accordance with the driving situation,
wherein the driver assistance system:
determines a setpoint value for at least one control variable of the steering system, and
conditionally requests the setpoint value from the steering system via a driver assistance interface,
wherein a monitoring function connected downstream of the driver assistance system and the driver assistance interface and connected upstream of the request to the steering system brings about a fault action in response to the setpoint value not satisfying a predefined permissibility criterion,
wherein the fault action causes the driver assistance system to newly determine a setpoint value, of a control variable rather than requesting the setpoint value, previously determined by the driver assistance system, wherein the newly determined setpoint value of the control variable newly determined by the driver assistance system is monitored and conditionally requested by the steering system, and/or
the monitoring function monitors setpoint values, determined by the driver assistance system, and monitors the newly determined setpoint value, of a plurality of control variables by an OR logic operation and/or by summation.
