Claim 0:
1. A driver-assistance-system-based steering assistance method for a transportation vehicle with a steering system with steering assistance for assisting a driver when steering the transportation vehicle using the steering system, the steering assistance method comprising:
sensing a driving situation of the transportation vehicle;
carrying out an intervention into the driving behavior of the transportation vehicle in accordance with the driving situation, wherein the underlying 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 by the monitoring function and conditionally requested by the steering system,
wherein 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.
