摘要： Method for controlling correct operation of a vehicle comprising the step of measuring a first group of parameters by means of physical sensors which define a first set of sensors. In this connection the vehicle which comprises the first set of sensors implements a procedure comprising the steps of: i) calculating a first parameter of the first group depending on at least the remaining parameters of the first group in a predefined number of standard operating conditions of the vehicle, said conditions being assessed during development of the vehicle/engine system; ii) assessing the deviation between a value of the first parameter calculated in step i) and a value of the first parameter measured in said step for measuring said first group of parameters by means of the physical sensors; iii) detecting an anomaly if said deviation exceeds a pre-set value.
