Abstract
A method for monitoring/controlling starting of a heat engine of a hybrid vehicle including at least one electrical engine, including: launching a pseudo-sequence for starting the heat engine by using a start battery; measuring and recording progress over time of at least one parameter of the start battery, including a given current strength and voltage at terminals of the start battery; and detecting whether or not the progress over time of the at least one parameter reaches a predetermined value defining a state of the start battery, with or without a required capacity, for starting the heat engine during a given time interval.

11. A method for commanding and controlling starting of a combustion engine of a hybrid vehicle including at least one electric motor, the method comprising:
-
beginning a pseudo starting sequence of starting the combustion engine using a starting battery; measuring and recording an evolution with respect to time of at least one parameter of the starting battery comprising a given current strength and a given voltage across terminals of the starting battery; detecting whether or not the evolution with respect to time of the parameter or parameters reaches a predetermined value defining a state of capacity of the starting battery of having or not having a capacity to start the combustion engine, over a given interval of time; if it is detected that the state of the starting battery has the capacity, starting the combustion engine, using the starting battery; and if it is not detected that the state of the starting battery has the capacity, allowing the electric motor to be used for propelling the hybrid vehicle and warning a driver that the detected state of the starting battery does not have the capacity. - View Dependent Claims (12, 13, 14, 15, 16)

17. A device for command and control of starting of a combustion engine of a hybrid vehicle comprising:
-
a combustion engine, at least one electric motor, a means of starting the combustion engine or a starter motor, a starting battery, all operated by a main electronic control unit, wherein the main electronic control unit is configured to; begin a pseudo starting sequence of starting the combustion engine by the starting means powered by the starting battery; measure and record an evolution with respect to time of at least one parameter of the starting battery comprising a given current strength and a given voltage across terminals of the starting battery; detect whether or not the evolution with respect to time of the parameter or parameters reaches a predetermined value defining a state of capacity of the starting battery of having or not having a capacity to start the combustion engine, over a given interval of time; if it is detected that the state of the starting battery has the capacity, starting the combustion engine, using the starting battery; and if it is not detected that the state of the starting battery has the capacity, allowing the electric motor to be used for propelling the hybrid vehicle and warning a driver that the detected state of the starting battery does not have the capacity. - View Dependent Claims (18, 19, 20)
