Method for monitoring health status of a chassis system of a vehicle

A method for monitoring health status of a chassis system of a vehicle, the chassis system comprising a plurality of subsystems of the chassis system of the vehicle, the vehicle comprising a new electronic control unit, a set of sensors, and a communication bus configured to convey signal data to the new electronic control unit, the new electronic control unit being configured to run a vehicle chassis system simulator based on a vehicle main physics-based model of the chassis system of the vehicle and based on a physics-based model of each subsystem of the chassis system of the vehicle, a first neural network, a second neural network, and a signal processor, the method comprising:

• collect signal data, the signal data comprising measured sensor data measured by at least one sensor of the set of sensors during a period of time;
• process, by the signal processor, the signal data, to produce processed signal data;
• feed processed signal data as input to the first neural network, trained for predicting a first neural network output, the first neural network output comprising a first set of data-driven subsystem health statuses;
• feed the signal data as input to the vehicle chassis system simulator, the vehicle chassis system simulator being configured to provide a vehicle chassis system simulation output based on the physics-based model of the vehicle chassis system and on the signal data, the vehicle chassis system simulation output comprising a second set of physics-based subsystem health statuses;
• provide the first set of data-driven subsystem health statuses and the second set of physics-based subsystem health statuses as input to the second neural network, the second neural network being configured to provide a second neural network output, the second neural network output being a set of consolidated subsystem health statuses;
• and
• depending on the set of consolidated subsystem health statuses, produce a support recommendation to temporarily correct failures indicated by the set of consolidated subsystem health statuses and send the set of consolidated subsystem health statuses to a support center to plan future support actions to permanently correct the failures.
