A software algorithm (Figure 3) determines the strategy by which a controller (34) will manage state of charge (SOC) of a battery pack (32) in a hybrid electric vehicle but always gives the driver the opportunity to make his/her own selection instead. The algorithm causes one of two strategies to be selected each time that the ignition switch is operated from "off' position to "on" position. The manner in which the algorithm executes depends on the value of a calibratable parameter electronically programmed into the controller of the particular vehicle when the vehicle is being built at the factory.

Un algorithme de logiciel (figure 3) détermine la stratégie par laquelle un dispositif de commande (34) gérera létat de charge (SOC) dun bloc-batterie (32) dans un véhicule électrique hybride mais donne toujours au conducteur lopportunité de faire plutôt sa propre sélection. Lalgorithme amène une des deux stratégies à être sélectionnée à chaque fois que le commutateur dallumage est actionné de la position « arrêt » à la position « marche ». La manière selon laquelle lalgorithme sexécute dépend de la valeur dun paramètre pouvant être étalonné programmé électroniquement à lintérieur du dispositif de commande du véhicule particulier, lors de la fabrication du véhicule à lusine.
