  • Patent number: 10814844
    Abstract: A braking controller and method in a towing vehicle towing one or more towed vehicles as a combination vehicle provides brake control of the one or more towed vehicles based on a level of braking force applied to the towing vehicle. A non-enhanced braking mode applies a first level of braking force to the towed vehicles in a predetermined reduced proportion relative to the level of braking force applied to the towing vehicle, and an enhanced braking mode applies a second level of braking force to the towed vehicles greater than the first level of braking force. The enhanced braking mode strategy is used unless trailer capability information reported by one or more the trailers fails to match against expected trailer capability information.

  • Patent number: 10798281
    Abstract: Various examples of a driver monitoring apparatus and a method of disabling a driver facing camera are disclosed. A driver monitoring controller receives video images of a driver and transmits control messages to a driver facing camera. The driver monitoring controller receives a signal indicating that the driver desires to disable the driver facing camera. The driver monitoring controller receives messages indicating a vehicle state. The control logic of the driver monitoring controller disables the driver facing camera by transmitting a control message to disable the driver facing camera in response to a control input indicating the driver desires to disable the driver facing camera and a vehicle state message indicating a vehicle state does not meet a predetermined condition. The control logic of the driver monitoring controller enables the camera automatically in response to a vehicle state message indicating the vehicle state meets the predetermined condition.

  • Patent number: 10780872
    Abstract: A system on a tractor for controlling trailer service brakes comprises a manually operated trailer brake switch, a first electropneumatic valve in communication with a pressure source and a controller. The controller has an input communicating with the trailer brake switch, an output communicating with the electropneumatic valve and control logic. The control logic receives an input from the trailer brake switch indicating a driver's request to apply the trailer service brakes of the combination vehicle, determines if a predetermined condition exists and transmits a signal to the output to the electropneumatic valve. The electropneumatic valve transmits pressure to a trailer service control line to actuate the trailer service brakes in response to the trailer brake switch and existence of the predetermined condition.

  • Patent number: 10783790
    Abstract: A system and method is described in which vehicles are configured to collect driver and vehicle event data, selectively compress and encode the collected driver and vehicle event data, and communicate the compressed and encoded data wirelessly to one or more telematics service providers. Servers poll this driver event data periodically, process it, and present multiple methods to end users by which they are able to view and analyze it. The present system permits fleet managers to use this driver event data, received through a report or notification, or pulled directly from a web-based portal, to monitor, correct or reward driver behavior, and to implement driver education and training programs.

  • Publication number: 20200290639
    Abstract: A method for providing user-specific driver assistance includes storing, in a vehicle, warning threshold preset values used to provide driver assistance warnings, and identifying a driver of the vehicle based on driver identification information. Sensors provide driver behavior data for the identified driver, which is then compared to desired driver behavior data. A modified warning value specific to the identified driver is then determined based at least in part on a result of the comparison. One or more of the plurality of warning threshold preset values may be updated based on the modified warning value, and a driver assistance warning may be provided to the identified driver in accordance with the updated one or more of the plurality of warning threshold preset values.

  • Patent number: 10769813
    Abstract: A calibration apparatus and method are provided for a surround-view camera system having a plurality of cameras mounted to an object (e.g., a vehicle). A plurality of markers are arbitrarily placed around the object and configured to measure a plurality of distances between one another. The markers preferably include a rangefinder to measure distances. From at least one image from one or more cameras, a controller is configured to visually identify at least two markers which define a coordinate system. Based on the measured plurality of distances between markers and the visually identified markers, the controller generates calibration information as an output, preferably saved in the form of a look-up table, which will be retrieved and used when a display device generates a bird's-eye view for a viewer. Additionally, a marker that is part of the calibration apparatus is provided.

  • Patent number: 10767717
    Abstract: A method for modifying a brake application of a combination vehicle comprises receiving a temperature signal of a first brake pad of a first brake assembly and receiving a temperature signal representative of a temperature of a second brake pad of a second brake assembly. The temperatures are compared to a first predetermined temperature. The method will determine if service brakes of the trailer are being applied by a driver and compare a wheel speed of the trailer with the wheel speed of a tractor of the combination vehicle. The method will determine a brake drag exists on the trailer in response to both the first and the second brake pad temperature being greater than the first predetermined temperature, the trailer wheel speed being less than the tractor wheel speed and the service brakes not being applied by the driver.

  • Patent number: 10755121
    Abstract: A driving oriented digital video recorder (DVR) system may comprise a camera; a memory; and a control circuit. The occurrence of a predefined driving event type may be determined based on received data. An event object that includes details of the determined event may be generated, including the type of the determined event and a time association with a segment of captured driving video. Metadata tags may be generated, which contain the type of the determined event and the location of the event object in the memory of the DVR. The DVR may retrieve segments of the driving video by identifying the metadata tag as having the same event type as a query parameter and, in turn, identify the event object using the location of the event object included in the metadata tag. The driving video segment may then be located via the association with the event object.
