    摘要： A system according to the principles of the present disclosure includes a rate determination module, a storage level determination module, and an air/fuel ratio control module. The rate determination module determines an ammonia generation rate in a three-way catalyst based on a reaction efficiency and a reactant level. The storage level determination module determines an ammonia storage level in a selective catalytic reduction (SCR) catalyst positioned downstream from the three-way catalyst based on the ammonia generation rate. The air/fuel ratio control module controls an air/fuel ratio of an engine based on the ammonia storage level.

    摘要： A method and system is provided for determining non-sensed vehicle operating parameters of a vehicle system. The method and system further provide for determining an engine air mass flow rate using the non-sensed vehicle operating parameters. A plurality of vehicle operating set-points may be determined using the non-sensed vehicle system operating parameters and the non-sensed engine air mass flow rate. A controller may use the vehicle operating set-points in order to control emissions of the vehicle system.

    摘要： Three-dimensional image data is generated. According to an example embodiment, three-dimensional depth information is estimated from a still image. A set of monocular images and their corresponding ground-truth depth maps are used to determine a relationship between monocular image features and the depth of image points. For different points in a particular image, the determined relationship is used together with local and global image features including monocular cues to determine relative depths of the points.
