1. A computer-implemented method for determining a condition value for a vehicle requirement related to a component or system in a vehicle, including:
providing a requirement quantification tool comprising a simulator, a memory storing information characterizing at least one first traffic use case on a first abstraction level and a generation function configured to generate, when executed, the condition value for the vehicle requirement from an observed parameter extracted from results of a simulation related to said first traffic use case performed by the simulator;
performing by the requirement quantification tool the steps of:
acquiring characterization information characterizing at least one second traffic use case on a second abstraction level, lower than the first abstraction level, each second traffic use case being associated with the first traffic use case,
for each second traffic use case, performing the steps of operating the simulator to run a simulation related to said second traffic use case, extracting a value for the observed parameter from the simulation results, and generating the condition value for the vehicle requirement from the extracted value of the observed parameter by executing the stored generation function,
wherein the first and second traffic use cases comprise sensing a stopped vehicle with a sensor, braking and stopping to avoid a collision with the stopped vehicle; and
wherein the condition value for the vehicle requirement represents a maximum distance sensing range or a maximum field of view sensing range of the sensor such that the vehicle stops within a safety distance of the stopped vehicle,
the method comprising configuring the vehicle, the vehicle including the sensor having the condition value.
