Method of inhibiting the automatic stop control system of the heat engine of a vehicle in congested traffic

Method of controlling the stopping and starting of a heat engine with which a vehicle is equipped, comprising:

• controlling stopping of the engine when the vehicle is in an engine stop request phase and not in predefined operating conditions opposed to a stopping of said engine, and
• controlling starting of the engine when the vehicle is in an engine start request phase and not in predefined operating conditions opposed to the starting of said engine,
• wherein said operating conditions of the vehicle opposed to the stopping of said engine comprise conditions of slow traffic, these conditions of slow traffic being the object of specific identification criteria, so that the engine is not stopped in the slow traffic conditions,
• wherein the operating conditions of the vehicle opposed to the stopping of said engine include:
• a condition wherein the moving speed of the vehicle is more than a first threshold value, wherein said first threshold value is more than zero, and
• a condition wherein the speed of the vehicle since the last time the engine has been started has not exceeded a second threshold value, wherein said second threshold value is more than zero, and the speed of the vehicle is equal or more than a third threshold value which is lower than the first predetermined threshold value, wherein said third threshold value is more than zero, so as to take into account the traffic conditions and notably a traffic jam situation.
