  • Patent number: 11884288
    Abstract: A method for classifying a weight of a vehicle includes determining a system enablement state of the vehicle load detection and classification system, monitoring a vehicle weight, determining a change in the vehicle weight, comparing the change in the vehicle weight to a first predefined weight change threshold, and categorizing the change in the vehicle weight in response to determining that the change in the vehicle weight exceeds the first predefined weight change threshold. The method also includes determining if a weight has been left in the vehicle after key-off and determining if a weight has been placed in a cargo compartment of the vehicle which exceeds the weight rating of the cargo compartment. The method also includes optimizing a route to a destination based at least on the change in the vehicle weight and displaying the optimized route to the destination using a human machine interface of the vehicle.

  • Patent number: 11887272
    Abstract: A spatial monitoring system employs a partial dimension iterative closest point analysis to provide improved accuracy for point cloud registration. The partial dimension iterative closest point analysis improves registration accuracy by performing optimization in accordance with an error magnitude of each dimension, wherein dimensions having large initial errors are significantly improved, and dimensions having high initial accuracy are further improved. The registration separately optimizes each dimension using surfaces with contributing information for the optimized dimension.

  • Patent number: 11885253
    Abstract: A method of controlling light-off of a catalytic converter in an exhaust system of an internal combustion engine (ICE) includes identifying a start of the ICE requiring a light-off of the catalytic converter. The method also includes regulating an exhaust-flow control valve to increase exhaust gas backpressure in the exhaust system in response to the identified start of the ICE. The method additionally includes regulating combustion inside the ICE to increase enthalpy of the ICE. The method also includes detecting light-off of the catalytic converter. The method additionally includes regulating the exhaust-flow control valve to decrease the exhaust gas backpressure in the exhaust system in response to the catalytic converter light-off. Furthermore, the method includes regulating combustion inside the ICE to decrease ICE enthalpy in response to the catalytic converter light-off. The method may be embodied in an algorithm programmed in an electronic controller of a motor vehicle.

  • Patent number: 11886184
    Abstract: An autonomous vehicle receives geographic location data defined via a mobile computing device operated by a user. The geographic location data is indicative of a device position of the mobile computing device. The autonomous vehicle also receives image data generated by the mobile computing device. The image data is indicative of a surrounding position nearby the device position. The surrounding position is selected from an image captured by a camera of the mobile computing device. A requested vehicle position (e.g., a pick-up or drop-off location) is set for a trip of the user in the autonomous vehicle based on the geographic location data and the image data. A route from a current vehicle position of the autonomous vehicle to the requested vehicle position for the trip of the user in the autonomous vehicle is generated. Moreover, the autonomous vehicle can follow the route to the requested vehicle position.
