摘要： A system and method determine (a) thermal characteristics of an energy storage apparatus that supplies electric current to one or more vehicular loads for powering the one or more vehicular loads and/or (b) electrical characteristics of the energy storage apparatus or the one or more vehicular loads. The system and method determine whether operation of the energy storage apparatus indicates that the energy storage apparatus is unexpectedly heating or unexpectedly cooling and identifying a fault in the energy storage apparatus responsive to determining that the energy storage apparatus is unexpectedly heating or unexpectedly cooling.

摘要： Methods are provided that may include determining one or more of a vibration characteristic or a fluid characteristic of one or more components of a vehicle and determining one or more expected characteristics for the one or more of the vibration characteristic or the fluid characteristic. The methods may also include determining whether the one or more of the vibration characteristic or the fluid characteristic deviates from the one or more expected respective characteristics, and implementing one or more responsive actions in response to determining that the one or more of the vibration characteristic or the fluid characteristic deviates from the one or more expected characteristics.

摘要： A sensor assembly includes a housing extending from an insertion end to an opposite coupling end, from a sensor end to an opposite back end, and from a top end to an opposite bottom end. The assembly also includes a sensor dish outwardly projecting from the sensor end of the housing and configured to hold one or more sensors. The assembly also includes a radio frequency (RF) transparent sensor cap configured to be secured to the sensor dish to secure the one or more sensors within the sensor dish. The housing also can be secured to a vehicle for the sensors to measure operational conditions of the vehicle. The housing of the sensor assembly may be connected to a drive train of the vehicle by inserting a fastener through a channel in the housing and into a jacking hole of the vehicle.

摘要： A system and method that identify a location and/or magnitude of a ground fault in a circuit having a bus that connects battery strings with loads and a ground reference between the loads are provided. Potential of the bus is shifted relative to a ground reference in a first direction. A first impedance in the bus between the battery strings and the ground reference is determined, and the bus is shifted relative to the ground reference in a second direction. A second impedance in the bus between the battery strings and the ground reference is determined. A location and/or severity of a ground fault is determined based on a relationship between the first impedance and the second impedance.

摘要： A vehicle sensor unit includes a communication device configured to communicate with one or more other sensor units, a controller of a vehicle system on which the vehicle sensor unit is disposed, and one or more sensors; a sensor configured to sense one or more characteristics of a vehicle on which the vehicle sensor unit is disposed; and a controller configured to determine one or more operating conditions of the vehicle based on the one or more characteristics that are sensed by the sensor. The controller is configured to control the communication device to communicate the one or more characteristics, the one or more operating conditions, or both the one or more characteristics and the one or more operating conditions. The communication device and the sensor are configured to be disposed onboard the vehicle that does not have an internal source of electric power.

摘要： A system and method includes a secondary energy storage system (SESS) and a control system. The SESS is configured to be disposed onboard a vehicle and conductively connected via switch devices to a primary battery and a cranking device of the vehicle. The control system is configured to control the switch devices to close a conductive path to discharge electric current from the SESS for powering the cranking device to rotate an engine shaft during a cranking operation. The control system is configured to control the switch devices to open the conductive path and prevent discharge of electric current from the SESS after the cranking operation is complete.

摘要： A sensor system includes one or more sensors that sense vibrations of a vehicle and one or more processors that can determine a speed of the vehicle and determine whether the vibrations occurring at one or more frequencies of interest (that are based on the speed of the vehicle) indicate damage to a propulsion system of the vehicle. The one or more processors optionally may determine a hunting frequency of a wheel and axle set and/or a lateral acceleration of the wheel and axle set from the vibrations. The one or more processors can determine a conicity of a wheel in the wheel and axle set based on the hunting frequency and/or the lateral acceleration that is determined.

摘要： A method includes generating movement signals indicative of sensed movement of a powered system in one or more directions and generating fluid level signals indicative of a sensed amount of fluid in the powered system. The method also includes, with one or more processors, receiving the movement signals and the fluid level signals from one or more accelerometers and a fluid level sensor, wherein the one or more processors also configured to filter at least some of the movement signals based on a speed at which the powered system operates. The method also includes, with a first antenna of the sensor assembly, wirelessly communicating one or more of the movement signals or the amount of fluid to a remote location.
