Method for optimizing passenger comfort in a railway vehicle

A comfort control device in a railway vehicle, for applying a comfort optimization method, including:

• at least one active suspension system, adjustable by means of a set of adjustment parameters,
• a system for controlling the set of adjustment parameters of the active suspension system,
• means for evaluating a comfort in the railway vehicle, and
• optimization means able to determine optimized sets of adjustment parameters by carrying out a plurality of optimization campaigns as follows:
• on a railway track cut out in segments, for each segment, the optimization campaigns are such that:
• during the first optimization campaign, at each passage of the active suspension system on the segment, a first set of adjustment parameters, specific to this passage, is predefined and applied to the active suspension system, and a comfort quality index is calculated, and then a metaheuristic algorithm is applied for determining second sets of adjustment parameters,
• during each following optimization campaign, at each passage of the active suspension system over the segment, one of the sets of adjustment parameters determined by the previous optimization campaign is applied to the suspension system and the comfort quality index is calculated, and then the metaheuristic algorithm is applied for determining new sets of adjustment parameters.
