Automated leaf spring failure-detection in heavy-duty vehicles

A heavy-duty vehicle, comprising:

• a leaf spring-suspended bogie;
• one or more angular velocity sensors configured to provide angular velocity data indicative of roll and pitch angular velocities of the leaf spring-suspended bogie;
• one or more deflection sensors configured to provide deflection data indicative of deflection of leaf springs of the bogie;
• and
• a computer system comprising processing circuitry configured to:
• receive the angular velocity data from the one or more angular velocity sensors;
• receive the deflection data from the one or more deflection sensors;
• and
• detect a failure of at least one leaf spring used to suspend the bogie based on the received angular velocity data and deflection data.

A computer-implemented method for detection of leaf spring failure in a leaf spring-suspended bogie of a heavy-duty vehicle, comprising:

• receiving, by processing circuitry of a computer system and from one or more angular velocity sensors, angular velocity data indicative of roll and pitch angular velocities of a leaf spring-suspended bogie of a heavy-duty vehicle;
• receiving, by the processing circuitry and from one or more deflection sensors, deflection data indicative of deflection of leaf springs of the bogie;
• and
• detecting, by the processing circuitry, a failure of at least one leaf spring used to suspend the bogie based on the received angular velocity data and deflection data.
