Method and device for monitoring/controlling the starting of a heat engine of a hybrid vehicle

摘要

A method for monitoring/controlling starting of a heat engine of a hybrid vehicle including at least one electrical engine, including: launching a simulated 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 predetermined time interval.

主权项

1. 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 simulated 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 the evolution with respect to time of the parameter or parameters reaches a predetermined value defining a state of the starting battery having a capacity to start the combustion engine over a predetermined 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 state of the starting battery, which was detected, does not have the capacity.
