  • Patent number: 11618291
    Abstract: A communication interface that facilitates communications over powerlines between a trailer and a vehicle. The communication interface includes a housing having first contact and a second contact accessible from an exterior of the housing. The first contact is electrically coupled to the second contact via a powerline that connects an electrical system of the vehicle with an electrical system of the trailer. The communication interface includes a powerline communication controller having a first set of terminals coupled to a first connector and a second set of terminals coupled to the powerline. The powerline communication controller is configured to receive a first signal from a device of the trailer that indicates a condition regarding a defined region of the trailer. The powerline communication controller is configured to generate, based on the first signal, a second signal representative of the condition, and introduce the second signal onto the first power signal.

  • Publication number: 20230086575
    Abstract: Dynamic throttle pedal filtering of a vehicle is provided. An automated throttle filtering system may be included in the vehicle that may operate to filter throttle pedal input based on detection of a rough driving surface. The rough driving surface detection may be based on an evaluation of wheel speed signals or an indication of traction loss. The throttle pedal input may be filtered corresponding to rough driving surface magnitude values determined based on the wheel speed signals. For example, filtered torque demand values may be determined based on the rough driving surface magnitude values and included in a torque demand request communicated to the vehicle's powertrain system. The resulting torque output may modulate an undesirable oscillating torque demand that may be generated in relation to operation of the vehicle on a rough driving surface.

  • Patent number: 11598278
    Abstract: A method of controlling an idle speed for an engine of a vehicle includes the steps of sensing a vehicle speed. At least one of a parking brake position and a clutch position is also sensed. When it is determined that the vehicle speed is below a maximum vehicle speed, and either the parking brake is released or the clutch is depressed, the engine idle speed is increased from a base idle speed to a launch idle speed.

  • Patent number: 11584232
    Abstract: Systems, methods and computer readable storage media provide a flexible and variability-accommodating instrument cluster for display on an in-vehicle screen and a user experience interaction model for providing vehicle status-related information via the instrument cluster. The instrument cluster may be shown in a minimized content view, basic content view, or enhanced content view, wherein each content view may include a varying range of displayed information based on a layout template. The driver can easily scroll between the various content views while driving. The instrument cluster may alternatively be shown in a favorites view, amongst a plurality of preconfigured favorites views associated with different drivers, the favorites view including a user-selected set of gauges in a user-selected layout. A steering wheel-based shortcut control is provided that can be assigned to a changeable parameter and used to toggle the parameter in association with an instrument cluster display element while driving.

  • Patent number: 11577610
    Abstract: Compact, multi-function rotational controllers or switches that allow an operator of a vehicle to simultaneously view the status of a plurality of related functions, and to easily change or toggle the status of each of the functions. A multi-function controller of the present disclosure may include a rotatable central control dial that is at least partially surrounded by a visual indicator panel that indicates a current status for the functions that are controlled by the multi-function controller. The multi-function controller may include a selected function indicator that indicates which of the plurality of related functions is currently selected, control input hardware that receives operator input, and control circuitry that toggles the state of the selected function responsive to such operator input. The multi-function controller may include an “all functions off” function that allows the operator to simultaneously turn all of the related functions off via a single input action.

  • Publication number: 20230012366
    Abstract: An on-board vehicle computer system receives a software update package from a remote computer system via a wireless communication network. The update package includes a software update for an updatable electronic component (e.g., an ECU) of the vehicle. Prior to installing the update, the vehicle computer system may check for a valid backup software version in a storage medium in the vehicle computer system to facilitate reversion to a previous software version in the event of an error during installation of the update. Installation of the update may be delayed until a compatible backup software version is obtained. After installation of the update, the system stores the update in the storage medium as the current backup software version for the updatable electronic component. This facilitates roll-back to a functional state in the event of an error during a future update.

  • Patent number: 11545715
    Abstract: The present disclosure is directed to a reversible battery tray that has a plurality of first boundary reception areas at a first side, and a plurality of second boundary reception areas at a second side opposite to the first side. The first boundary reception areas have a first shape to receive a first type of battery with a corresponding second shape, and the second boundary reception areas have a third shape to receive a second type of battery with a corresponding fourth shape. The reversible battery tray may be positioned within a battery box such that the first side is exposed or the second side is exposed as selected by a user or an operator of a vehicle to utilize different types of batteries while also restraining movement of the selected type of battery by the user or the operator as well.

  • Publication number: 20220410888
    Abstract: Automated launch torque is provided. An automated virtual launch torque generation (AVL-TG) system may be included in a vehicle, such as a heavy duty truck, that may interoperate with an adaptive cruise control (CC) system to move the vehicle from a standstill or low speed to a CC handover speed. The AVL-TG system may determine a tip-in torque curve configured to mimic a torque curve generated by a human operator's acceleration pedal tip-in from a standstill or low speed. The tip-in torque curve may be represented by torque demand values corresponding to a dynamic pedal saturation level applied over a dynamic pedal rate. The torque demand values determined by the AVL-TG system may mimic an expected or human vehicle operator generated torque request, and may operate to successfully close the clutch and smoothly launch the vehicle from a standstill or low speed.

  • Patent number: 11536183
    Abstract: An exhaust aftertreatment system and associated system for purifying an exhaust gas feedstream of a lean-burn engine includes an oxidation catalyst that is arranged upstream of a selective catalytic reduction (SCR) catalyst. A first NOx sensor is arranged upstream, and a second NOx sensor is arranged downstream of the oxidation catalyst. A controller is arranged to monitor the oxidation catalyst based upon inputs from the first and second NOx sensors. A first NOx parameter is determined via the first NOx sensor, and a second NOx parameter is determined via the second NOx sensor. An NO2 parameter is determined based upon the first NOx parameter, the second NOx parameter, a first relationship for the first and second NOx sensors, and a second relationship for the first and second NOx sensors. The NO2 production of the oxidation catalyst is evaluated based upon the NO2 parameter.
