摘要：
Various methods and systems are provided for estimating engine fuel consumption. In one example, a method comprises controlling an engine according to a control map, the control map specifying control settings according to a predetermined relationship with respect to engine speed and engine load. The method further comprises estimating fuel consumption of the engine based on each of: an electric-machine based engine load indicated by an electric machine coupled to the engine; and further based on the predetermined relationship.
