System and method for detecting an abnormal gait condition of a railway vehicle

A method for detecting an abnormal gait condition of a railway vehicle, the method comprising:

• acquiring first detection data of one or more of an attitude or a movement of the railway vehicle using a first sensor of a first control chain;
• communicating the first detection data from the first sensor to a first control unit of the first control chain;
• executing a first computer program for checking the abnormal gait condition of the railway vehicle in a first control unit of the first control chain;
• controlling, by the first control unit, a first electronic control device of the first control chain as a function of decisions of the first computer program for checking the abnormal gait condition of the railway vehicle, for supplying or not supplying power to a discharge valve of a brake pipe;
• acquiring second detection data of the one or more of the attitude or the movement of the railway vehicle using a second sensor of a second control chain, the second sensor different from the first sensor;
• communicating the second detection data from the second sensor to a second control unit of the second control chain, the second control chain different from the first control unit;
• executing a second computer program for checking the abnormal gait condition of the railway vehicle, the second computer program different from the first computer program for checking the abnormal gait condition of the railway vehicle, the second computer program executed in the second control unit of the second control chain;
• and
• controlling, by the second control unit, a second electronic control device of the second control chain, the second electronic control device different from the first electronic control device, the second electronic control device controlled as a function of decisions of the second computer program for checking the abnormal gait condition of the rail vehicle, for supplying or not supplying the power to the discharge valve.

A system comprising:

• different first and second sensors each configured to detect one or more of an attitude or movement of a vehicle;
• a first control device configured to detect an abnormal gait of vehicle based on output of the first sensor indicative of the one or more of the attitude or the movement of the vehicle;
• and
• a second control device that is different from the first control device and that is configured to detect the abnormal gait of the vehicle based on output of the second sensor indicative of the one or more of the attitude or the movement of the vehicle,
• each of the first control device and the second control device configured to control supply of current to a discharge valve of a brake pipe in the vehicle based on the abnormal gait of the vehicle being detected.
