Abstract

The disclosure includes implementations for supervising a data load for a vehicle. The method may include receiving report data that may describe a data load for the supervised component. The method may include retrieving specification data for the supervised component that describes a threshold for the data load. The method may include performing an analysis of the data load to determine whether the data load exceeds the threshold. The method may include providing graphical data to an electronic display panel to cause the electronic display panel to display a message responsive to the analysis indicating that the data load exceeds the threshold. The method may include providing an accommodation to the supervised component so that the data load does not exceed the threshold, where the accommodation includes stopping an operation of a device of the vehicle.

Claims

1. A system of a vehicle comprising:

one or more hardware processors coupled to a memory;

a supervised component including a report module stored in the memory and executable by the one or more hardware processors of the vehicle;

a data load supervisor stored in the memory and executable by the one or more hardware processors of the vehicle; and

an electronic display panel communicatively coupled to the data load supervisor, wherein the electronic display panel is an element of the vehicle;

wherein the supervised component is communicatively coupled to the data load supervisor via a communicative coupling;

wherein the report module provides load data to the data load supervisor via the communicatively coupling;

wherein the load data describes a data load of the supervised component;

wherein the data load supervisor performs an analysis of the data load to determine whether the data load exceeds a threshold described by a specification associated with the supervised component;

wherein responsive to the data load supervisor determining that the supervised component cannot handle the data load without an accommodation, the data load supervisor stops an operation of a device of the vehicle; and

wherein the data load supervisor causes the electronic display panel to display a message responsive to the analysis.

2. The system of claim 1, wherein the supervised component is an electronic control unit of the vehicle that includes the report module.

3. The system of claim 1, wherein the supervised component is an onboard vehicle computer of the vehicle that includes the report module.

4. The system of claim 1, wherein the supervised component is a network-enabled device of the vehicle that includes the report module.

5. The system of claim 1, wherein the communicative coupling that communicatively couples the supervised component and the data load supervisor is a hard wired communicative coupling.

6. The system of claim 1, wherein the communicative coupling that communicatively couples the supervised component and the data load supervisor is a wireless communicative coupling.

7. The system of claim 1, wherein the report module provides the load data to the data load supervisor via Bluetooth.

8. The system of claim 1, wherein the report module provides the load data to the data load supervisor via Wi-Fi.

9. The system of claim 1, wherein the report module provides the load data to the data load supervisor via Dedicated Short Range Communication.

10. The system of claim 1, wherein the electronic display panel is an element of a head unit included in the vehicle and the head unit is communicatively coupled to the data load supervisor to receive graphical data for causing the electronic display panel to generate a graphical user interface that includes the message.

11. The system of claim 1, wherein the vehicle is an autonomous vehicle and the autonomous vehicle navigates to a break-down lane and powers down responsive to the analysis.

12. A method comprising:

providing, by a report module that is an element of a supervised component of a vehicle, load data to a data load supervisor of the vehicle via a communicatively coupling shared between the supervised component and the data load supervisor, wherein the load data describes a data load of the supervised component;

providing, by the data load supervisor, an analysis of the data load to determine whether the data load exceeds a threshold described by a specification associated with the supervised component;

responsive to determining that the supervised component cannot handle the data load without an accommodation, stopping, by the data load supervisor, an operation of a device of the vehicle; and

providing, by the data load supervisor, graphical data to an electronic display panel to cause the electronic display panel to display a message responsive to the analysis.

13. The method of claim 12, wherein the analysis indicates that the data load exceeds the threshold and the message suggests that the vehicle stop driving immediately.

14. The method of claim 12, wherein the analysis indicates that the data load exceeds the threshold and the message suggests that the vehicle be serviced by a technician.

15. The method of claim 12, wherein

the accommodation further includes one or more of throttling a future data load placed on the supervised component and stopping an operation of a function that would result in an increase in the data load for the supervised component.

16. A computer program product comprising a non-transitory memory storing computer-executable code that, when executed by a processor, causes the processor to:

receive report data from a communicative coupling shared with a supervised component that includes a report module that transmits a message including the report data, wherein the report data describes a data load for the supervised component that is an element of a vehicle;

retrieve specification data for the supervised component that describes a threshold for the data load;

perform an analysis of the data load to determine whether the data load exceeds the threshold;

provide graphical data to an electronic display panel to cause the electronic display panel to display a message responsive to the analysis indicating that the data load exceeds the threshold; and

provide an accommodation to the supervised component so that the data load does not exceed a value that is substantially equal to the threshold, wherein the accommodation includes stopping an operation of a device of the vehicle.

17. The computer program product of claim 16, wherein the message suggests that the vehicle stop driving immediately.

18. The computer program product of claim 16, wherein the message suggests that the vehicle be serviced by a technician.

19. The computer program product of claim 16, wherein the accommodation includes throttling a future data load placed on the supervised component.

20. The computer program product of claim 16, wherein the accommodation further includes stopping an operation of a function that would result in an increase in the data load for the supervised component.
