Method of learning the neutral position in a vehicle equipped with an internal combustion engine with a stop and start system

A method of learning the neutral position in a vehicle equipped with an internal combustion engine with a Stop and Start system. The method provides for learning the duty cycle values associated with the odd gears (ODD) and the even gears (EVEN) engaged during vehicle running, determining the maximum duty cycle value (ODD max ) for the odd gears (ODD) and the minimum duty cycle value (EVEN min ) for the even gears (EVEN), determining a duty cycle band to which the neutral gear condition (N) corresponds on the basis of the minimum duty cycle value (EVEN min ) for the even gears (EVEN) and the maximum duty cycle value (ODD max ) for the odd gears (ODD), and controlling the Stop and Start system on the basis of the duty cycle band to which the neutral gear condition (N) corresponds.
