Abstract: A method of controlling a vehicle equipped with an internal-combustion engine with a “stop and start” system. The method provides, during vehicle running, for learning the “duty cycle” values associated with the odd gears and even gears, determining the “maximum duty cycle” value for the odd gears and “minimum duty cycle” value for the even gears, determining a duty-cycle band to which the “neutral gear” condition corresponds on the basis of the “minimum duty cycle” value for the even gears and “maximum duty cycle” value for the odd gears, and controlling the “stop and start” system on the basis of the duty-cycle band to which the “neutral gear” condition corresponds.

Abstract: Method to control the sealing of a blow-by gas breather circuit of an internal combustion engine, comprising a separator device to agglomerate the particles of finely atomised lubricating oil and to remove the solid particulate particles and having an outlet connected by a pipe to an intake pipe through which the gas purified from the lubricating oil and the particulate flows out and a pressure sensor; the method providing the following steps: acquiring the signal coming from said pressure sensor; filtering the signal coming from the pressure sensor; integrating over time the square of the filtrated signal coming from the pressure sensor; and determining the sealing of the pipe according to the integrated signal which is the combustion energy generated by the internal combustion engine.
