Example control methods and apparatus are described. One example control method includes obtaining, by a first controller, a first operating status of the first controller before a control function of the first controller and/or a control function of a second controller are/is activated. The first controller receives first indication information sent by the second controller, where the first indication information indicates a controller status of the second controller. The first controller sets a first controller mode of the first controller based on the first operating status and the first indication information. Second indication information is sent by the first controller to the second controller, so that a first controller mode of the second controller that is set by the second controller does not conflict with the first controller mode of the first controller.

The diagnostics electrical architecture comprises: one or more electronic control units each comprising a diagnostics server module; a service interface module arranged to allow diagnostic communication between the one or more electronic control units and a network service bus of the vehicle; and a diagnostic services registry module. The method comprising: performing, by the diagnostics server module, diagnostic tasks to generate diagnostic object data; receiving into the service interface module the generated diagnostic object data; retrieving diagnostic services data from the diagnostic service registry module, the diagnostic services data comprising diagnostic capability descriptions of the generated diagnostic object data; and transmitting a diagnostic service notification over the network service bus, the diagnostic service notification being based on the generated diagnostic object data and the diagnostic services data.

A switch arrangement for providing alternative distribution paths in a system for distributing electrical power in a vehicle including electrical power supplies and electrical loads. The switch arrangement includes a first switch adapted to be connected to a first electrical element, a second switch adapted to be connected to the first electrical element and a second electrical element, and a third switch adapted to be connected to the electrical element and a third electrical element. Each of the first, second, and third switches is independently controllable, and selective operation of each of the first, second, and third switches to its open or closed state interconnects at least two of the first, second, and third electrical elements to establish one of multiple alternative distribution paths to connect one of the power supplies and one of the loads or to connect two of the power supplies.

An in-vehicle network system includes a power source, an upper electronic control unit (ECU), a first intermediate ECU and a second intermediate ECU, at least one first lower ECU and at least one second lower ECU, a power source relay, and a communication relay provided between the first communication path and the second communication path. When the upper ECU detects that an anomaly occurs in the first intermediate ECU, the power source relay and the communication relay are controlled such that a first power source path and a second power source path are connected to each other and a first communication path and a second communication path are connected to each other, and the second intermediate ECU performs electric power supply to and communication management of the first lower ECU.

A power management system is disclosed for managing power in a vehicle. The system may include a power distribution unit (PDU) communicably coupled to a power controller unit located in the vehicle. The power controller unit comprises a microcontroller configured to: receive, from the PDU, a temperature value that indicates a temperature of the PDU, one or more voltage values from the one or more voltage sensors, or one or more current values from the one or more current sensors, perform a determination that the temperature value, the one or more voltage values, or the one or more current values are below one or more of their respective pre-determined threshold values, and send, after the determination, a health status message to a computer located in the vehicle, where the health status message indicates that the PDU is operating in a safe operating condition.

Methods, apparatus, systems, and articles of manufacture are disclosed to generate an augmented environment including a weight indicator for a vehicle. An example disclosed system includes a camera to capture image data including a first location of an object in a vehicle, processor circuitry to execute instructions to generate a map of loads on the vehicle, and a user interface to present an augmented environment identifying the first location of the object and a load correlated with the object, the load correlated with the object based on the map of loads.

Performing in-vehicle network diagnostics is provided. A cloud system receives wiring diagnostic data from a vehicle. The wiring diagnostic data includes information with respect to electrical operation of a plurality of segments of wiring of the vehicle. A machine-learning model of the cloud system is utilized to analyze the wiring diagnostic data. Responsive to the machine-learning model identifying an issue with the electrical operation based on the wiring diagnostic data, a response is sent from the cloud system to the vehicle, the response including one or more corrective actions to be performed by the vehicle to address the issue.

An in-vehicle system includes a zone control unit and lower-level control units. The zone control unit includes: a power supply control unit configured to control power supply to each of the lower-level control units; a communication control unit configured to control communication with each of the lower-level control units; and an abnormality detection unit configured to detect presence or absence of an abnormality in each of the lower-level control units. In a case in which an abnormality for two or more of elements including a power supply current value, a communication response time, and a MAC address is detected in at least one of the lower-level control units, the abnormality detection unit is configured to recognize that the at least one of the lower-level control units is an unauthorized device.

Embodiments of the present disclosure relate to an apparatus for operating an over-the-air (OTA) update for a vehicle including a generation device generating starting control information of the vehicle based on information about an OTA update of the vehicle and a transmission device transmitting the generated starting control information.

An electrical system in a vehicle has a battery is configured to supply electrical current when a driver ignition key is in a Key-Off state. A. A plurality of electrical loads are each configurable to receive the electrical current flowing from the battery during the Key-Off state depending upon predetermined Key-Off-Load (KOL) Modes. A vehicle locator determines a geographic location of the vehicle. A sleep-time database records daily Key-On and Key-Off events according to changes between the Key-On state and the Key-Off state, wherein each Key-Off event is associated with a respective geographic location from the vehicle locator. An analyzer identifies Key-Off events sharing a repetitive time span and a common geographic location. A scheduler activates a timed KOL sequence according to the identified Key-Off events so that repetitive time slots of vehicle usage can be used to reduce battery drain during times when vehicle usage is less likely.
