摘要： Systems for detecting movement of a trailer having a rearward facing camera and linked to a tow vehicle. The systems include taking a first image and a second image with the camera and comparing the images. A first amount of trailer movement is determined between the second image and the first image. The systems may also take additional images and determine a second amount of trailer movement occurring between the additional images. Tracking the first amount and the second amount of trailer movement determines an amount of trailer sway. The determined trailer sway may be compared to a maximum allowable sway and, if the movement is greater than the maximum allowable sway, mitigating sway of the trailer with the tow vehicle.

摘要： A system in a vehicle includes a lidar system to transmit incident light and receive reflections from one or more objects as a point cloud of points. The system also includes processing circuitry to identify planar points and to identify edge points of the point cloud. Each set of planar points forms a linear pattern and each edge point is between two sets of planar points, and the processing circuitry identifies each point of the points of the point cloud as being within a virtual beam among a set of virtual beams. Each virtual beam of the set of virtual beams representing a horizontal band of the point cloud.

摘要： Presented are mobile charging stations for recharging electrified vehicles, methods for making/using such mobile charging stations, and parking facilities equipped with such mobile charging stations. A mobile charging station includes a frame with drive wheels and a prime mover operable to drive the wheels to propel the charging station. A hydrogen storage container and fuel cell are mounted to the frame. The fuel cell oxidizes hydrogen received from the storage container to generate electrical current. An electrical coupling mechanism connects the fuel cell to a battery pack of an electric-drive vehicle. A resident or remote controller is programmed to receive charge requests to recharge vehicles, and responsively determines path plan data for the mobile charging station. The controller commands the prime mover to propel the mobile charging station from the charger's origin to a charger destination, and enables the fuel cell to transmit electrical current to the vehicle.

摘要： A system includes a diagnostic step module and an optimal diagnostic procedure module. The diagnostic step module is configured to identify diagnostic steps of a service procedure to be performed to diagnose a root cause of a fault on a vehicle based on a diagnostic trouble code identifying the fault, and identify a cost associated with performing each of the diagnostic steps. The optimal diagnostic procedure module is configured to determine an order in which to perform the diagnostic steps that minimizes the cost of diagnosing the fault, and output an optimal diagnostic procedure that indicates the diagnostic steps and the order in which to perform the diagnostic steps.

摘要： An air intake system for an internal combustion engine is described, and includes a vapor capture element disposed in an interior portion of an air intake system. The vapor capture element includes a flexible Metal Organic Framework (MOF) material, wherein the flexible MOF material is reversibly controllable to a first state and to a second state in response to a control stimulus. The flexible MOF material is configured to adsorb hydrocarbon vapor when controlled to the first state and configured to desorb the hydrocarbon vapor when controlled to the second state.

摘要： An electrified drivetrain for a vehicle includes a first electric machine, a second electric machine, a clutch, an HVAC compressor, and a controller. The second electric machine is rotatably coupled to a geartrain, the first electric machine is rotatably coupled to the HVAC compressor, and is rotatably couplable to the geartrain via the clutch, and the clutch is operative in a first state and a second state. The first electric machine is rotatably coupled to the geartrain when the clutch is controlled to the first state, and is decoupled from the geartrain when the clutch is controlled to the second state. The controller is operatively connected to the first and second electric machines, the clutch, and the HVAC compressor to control operation of the electrified drivetrain. The first electric machine can be used as a heater element and to provide mechanical power to the drivetrain.
