The invention relates to a method for calculating a management setpoint for the consumption of fuel and of electric current by a hybrid motor vehicle including at least one electric motor that is supplied with electric current by a traction battery and an internal combustion engine that runs on fuel. According to the invention, this method comprises steps of: a) acquiring a journey to be made; b) dividing said journey into successive segments; c) acquiring, for each segment, attributes that characterize said segment, a first of said attributes relating to the authorized or unauthorized character with regard to the use of the internal combustion engine over said segment; d) for each of said segments, acquiring a relationship relating the fuel consumption of the hybrid motor vehicle over the segment to its electrical power consumption; e) determining an optimal consumption point in each of the relationships acquired so as to maximize the discharging of the traction battery over the segments for which the first attribute indicates that use of the internal combustion engine is not authorized, minimize the fuel consumption of the hybrid motor vehicle over the entire journey, and maximize the discharging of the traction battery upon completion of the journey; and f) managing a setpoint for power management over the entire journey, according to the coordinates of said optimal points.
本发明涉及一种混合动力机动车辆的燃料消耗和电流消耗的管理设定点的计算方法,该混合动力机动车辆包括由牵引电池供应电流的至少一个电动机以及靠燃料运行的内燃发动机。根据本发明,此方法包括以下步骤:a)获取待行进行程;b)将所述行程划分成连续的节段;c)针对每个节段获取表征所述节段的属性,所述属性中的第一属性与关于在所述节段上使用内燃发动机的授权或未授权特性相关;d)针对所述节段中的每个节段,获取将该混合动力机动车辆在该节段上的燃料消耗与其电功率消耗相关的关系;e)确定所获取的关系中每一者的最优消耗点,从而使该牵引电池在该第一属性指示未授权使用该内燃发动机的这些节段上的放电最大化、使该混合动力机动车辆在整个行程上的燃料消耗最小化并且使该牵引电池在该行程结束时的放电最大化;以及f)根据所述最优点的坐标形成整个行程上的功率管理设定点。
