Wheeled vehicle provided with an automatic stop function for stopping the heat engine and method for optimizing stoppage conditions of such a vehicle

A wheeled vehicle comprising

• a chassis, a heat engine borne by said chassis, a starter of said engine and at least one member for actuating said starter,
• a control unit,
• a member for energizing at least the control unit, said energizing member being able to switch from an active state to an inactive state and vice versa,
• said vehicle comprising an economical operating mode in which, in the activated state of the energizing member and in the started state of the engine, the control unit is configured to allow the engine to be stopped automatically without actuation of the energizing member, said stopping being called energized stopping of the engine,
• wherein the wheeled vehicle comprises a memory for storing data relating to the number of starts of the heat engine of the vehicle and in that the control unit is configured to, in the economical operating mode of the vehicle, allow or prohibit the energized stopping of the engine at least according to said stored data,
• wherein the wheeled vehicle comprises the memory for storing each time value relating to the elapsed energized time between two successive starts of the heat engine and in that the control unit is configured to, n being an integer number greater than or equal to 1,
• calculate the sum of the last n stored time values with the time value relating to the elapsed energized time since the current start,
• compare said calculated value with a predetermined threshold value, and,
• allow the energized stopping of the engine at least according to the result of the comparison.
