  • METHOD AND DEVICE FOR MONITORING/CONTROLLING THE STARTING OF A HEAT ENGINE OF A HYBRID VEHICLE
    Publication number: 20150308398
    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.
