An embodiment of the present invention relates generally to a compute system, and more particularly to a mobile compute system with an interface verification mechanism.
Modern compute systems, especially transportation systems, are providing increasing levels of functionality to support modern life including additional status monitoring, connectivity services, and diagnostic services. Technology has enabled increased diagnostic information and usage of the diagnostic information for a vehicle. Research and development in the existing technologies can take a myriad of different directions.
As users become more dependent on the advantages provided by monitoring systems, in some cases the interface between the on-board diagnostic system and the monitoring system can be suspect and provide unreliable information to the user. Historically, intermittent connectivity problems have been the most difficult and expensive to resolve.
Thus, a need still remains for a mobile compute system with an interface verification mechanism. In view of the ever-increasing commercial competitive pressures, along with growing consumer expectations and the diminishing opportunities for meaningful product differentiation in the marketplace, it is increasingly critical that answers be found to these problems. Additionally, the need to reduce costs, improve efficiencies and performance, and meet competitive pressures adds an even greater urgency to the critical necessity for finding answers to these problems.
Solutions to these problems have been long sought but prior developments have not taught or suggested any solutions and, thus, solutions to these problems have long eluded those skilled in the art.
An embodiment of the present invention provides a method of operation of a mobile compute system including: identifying a vehicle prepared to travel by monitoring an on-board diagnostics; detecting an unplug event based on a message from the on-board diagnostics; detecting a trip in progress during the unplug event; and transferring the message identifying a loose connector pin in an on-board diagnostic port during the trip in progress for displaying on a device.
An embodiment of the present invention provides a mobile compute system, including: a communication unit configured to: transmit a message, identifying a vehicle prepared to travel, through an on-board diagnostic, and receive the message from the on-board diagnostic identifying a loose connector pin in an on-board diagnostic port; a control circuit, coupled to the communication unit, configured to: determine an unplug event has occurred, detect a trip in progress during the unplug event, and transfer the message, to identify the loose connector pin in the on-board diagnostic port, for displaying on a device.
An embodiment of the present invention provides a non-transitory computer readable medium including instructions executable by a control circuit for a mobile compute system, including: identifying a vehicle prepared to travel by monitoring an on-board diagnostics; detecting an unplug event based on a message from the on-board diagnostics; detecting a trip in progress during the unplug event; and transferring the message identifying a loose connector pin in an on-board diagnostic port during the trip in progress for displaying on a device.
Certain embodiments of the invention have other steps or elements in addition to or in place of those mentioned above. The steps or elements will become apparent to those skilled in the art from a reading of the following detailed description when taken with reference to the accompanying drawings.
Embodiments provide the mobile compute system can minimize the complexity of detecting and identifying intermittent couplings between the on-board diagnostic system and a monitoring system by detecting the message group of the controller area network. The identification of the messages of the controller area network allows the compute system to match the message group with a footprint to monitor the integrity of the coupling between the on-board diagnostic system and the monitoring system of the vehicle of the compute system.
Embodiments provide the mobile compute system can identify the configuration and operational status of subsystems of the vehicle of the mobile compute system by processing the messages of the controller area network. The correct identification of the message group from the controller area network can allow the mobile compute system to identify the configuration and operational status of subsystems of the vehicle. As an example, the mobile compute system can determine the configuration and operational status of subsystems of the vehicle by comparing the message group to a database of identified vehicles.
Embodiments provide the simplified and robust determination of the configuration and operational status of subsystems based on the message group obtained by the on-board diagnostics from the controller area network without decoding the vehicle identification from the controller area network. For example, the mobile compute system can determine the configuration and operational status of subsystems of the vehicle when the vehicle identification cannot be decoded by the on-board diagnostics from the controller area network. As a further example, the mobile compute system can determine the configuration and operational status of subsystems of the vehicle before the on-board diagnostics decodes the vehicle identification from the controller area network.
Embodiments provide improvements to the reliability of the mobile compute system by processing the message group in the controller area network to verify the configuration and operational status of subsystems utilizing the vehicle identification. The controller area network vehicle identification mechanism can verify that the proper diagnostic information is being provided from the vehicle based on the vehicle make, the vehicle model and the model year. As an example, the mobile compute systems can correctly gather accurate records for the vehicle by accessing specific original equipment manufacturer (OEM) parameters for the vehicle.

For ease of description, the instance of a loose connector pin 416 is shown in the connector pin 404 located in position 14, as part of the ISO 15765 CAN 410. It is understood that this is an example only and the occurrence of the loose connector pin 416 can be in any of the positions in the connector body 402. The loose connector pin 416 can cause unreliable communication between the controller area network 226 of the vehicle 202 of
The loose connector pin 416 can make intermittent electrical connection between the controller area network 226 and the on-board diagnostic dongle 232. The resulting communication difficulties can result in error messages sent on the controller area network 226 and misinterpreted communication with the on-board diagnostic dongle 232.
Referring now to
The controller area network 226 can include a node 504 and can connect a number of instances of the node 504. Examples of the node 504 can include the vehicle communication circuit 204, the vehicle control circuit 206, the vehicle storage circuit 208, other hardware circuits, or a combination thereof.

For example, the node 504 can send and receive a message 506 along the controller area network 226. The on-board diagnostic dongle 232 can interact with the node 504 can send and receive the message 506. The on-board diagnostic dongle 232 can monitor the operations of the node 504 in order to collect information on the operational status of the vehicle 202. The on-board diagnostic dongle 232 can also identify intermittent or the loose connector pin 416 in the on-board diagnostics port 228.
The node 504 can also communicate with an external entity or database. For example, the node 504 can receive data, control commands, or a combination thereof from an external entity or database. As a further example, the node 504 can transmit data, control commands, or a combination thereof to an external entity or database.
For brevity and clarity, the description for the controller area network 226 will be described with the node 504 representing any devices connected to an instance of the vehicle bus 502 of the controller area network 226, as examples described earlier. The instances of the node 504 can be similar, same, or different connected to the controller area network 226 including the subsystems 230.
The message 506 is a packet of data, control commands, or a combination thereof that is transmitted along the vehicle bus 502 of the controller area network 226. For example, the message 506 can provide information about the systems or subsystems in the vehicle 202. As examples, the message 506 can include control commands, status information, error information, queries, or a combination thereof. The on-board diagnostic dongle 232 can monitor the message 506 in order to identify how the vehicle 202 is being driven, where the vehicle 202 is travelling, and the operational status of the vehicle 202.

The gateway module 602 can prevent the on-board diagnostics 222 from receiving the message 506 that is transmitted along the controller area network 226. The gateway module 602 converts the message 506 along the controller area network 226 when communicating with the on-board diagnostics 222, the node 504 connected to the on-board diagnostics port 228, or a combination thereof. For example, the on-board diagnostics 222, the node 504 connected to the on-board diagnostics port 228, or a combination thereof is unable to receive the message 506 through the gateway module 602 prior to authentication of the on-board diagnostic dongle 232. After the authentication process, the on-board diagnostic dongle 232 can communicate with the node 504 to receive the message 506.
In the event the loose connector pin 416 causes a disconnect to be detected, the gateway module 602 would require the on-board diagnostic dongle 232 to be authenticated again before normal communication can commence. The on-board diagnostic dongle 232 can detect the unexpected authentication process from the gateway module 602 and report the suspected loose connector pin 416 in the on-board diagnostics port 228.

In the example shown in
If the unplug event detection 704 does identify a problem, the control flow 701 proceeds to the report disconnect module 706. The report disconnect module 706 can transfer the message 506 from the on-board diagnostic dongle 232 to the first user interface 318 of
The control flow 701 proceeds to a trip in progress detection 708 to determine whether the unplug event detection 704 was during a trip in progress. The trip in progress can be any movement of the vehicle 202 between two locations as determined by the first location circuit 320 of
If the third occurrence check 710 does determine that the unplug event detection 704 has occurred three times within the seven day period, the control flow proceeds to a display message loose connector pin detected module 712. The display message loose connector pin detected module 712 can transfer the message 506 from the on-board diagnostic dongle 232 to the first user interface 318 of
In the event that the detect new car event module 702 is initiated and the unplug event detection 704 does not detect any issues, the control flow proceeds to the monitor vehicle functions module 714, in which the on-board diagnostic dongle 232 can receive the message 506 detailing the status and operations of the subsystems 230 of
The control flow 701 then proceeds to the monitor vehicle location/route module 716, in which the on-board diagnostic dongle 232 can receive the message 506 from the first location circuit 320 detailing the current position, direction, and velocity of the vehicle 202. It is understood that the first control circuit 312 of
The control flow 701 proceeds to the record trip statistics module 718 to compile pertinent information about the movement of the vehicle 202. By way of an example, the on-board diagnostic dongle 232 can be configured to monitor where the vehicle 202 goes and how it is controlled. This can be pertinent to an insurance monitoring version of the on-board diagnostic dongle 232 or a parent monitoring a teenage driver through the on-board diagnostic dongle 232.
It is understood that the goal of the record trip statistics module 718 can be configured for other purposes, including monitoring mileage of the vehicle 202 used in business, to manage the maintenance schedule of the vehicle 202, to document how the vehicle 202 is controlled during a trip, to monitor whether the vehicle 202 deviates from a planned route during the trip, or a combination thereof. Since the subsystems 230 communicating through the controller area network 226 can provide extremely detailed information about the status and operation of the subsystems 230 and the vehicle 202 in general, the on-board diagnostic dongle 232 can be configured to selectively record specific portions of the message 506 that apply to the goal of the user.
The control flow 701 then proceeds to the transfer trip statistics for display module 720, in which the on-board diagnostic dongle 232 having detected that the trip is complete, can compose the message 506 for transfer to the to the first user interface 318 to display the message 506 alerting the user of the trip statistics pertinent to the user. It is understood that the first control circuit 312 and the first communication circuit 316 are utilized to receive the message 506 sent by the on-board diagnostic dongle 232. The transfer trip statistics for display module 720 can include a status of the unplug event 704 detected during the trip. The status of the unplug event 704 can provide a history to aid in analysis of an intermittent one of the loose connector pin 416.
In the control flow 701, if the unplug event detection 704 occurs but a trip in progress detection 708 is negative, meaning the vehicle 202 is not travelling at the time the unplug event detection 704 occurs, the control flow 701 proceeds to the monitor vehicle function module 714. Also, if the unplug event detection 704 occurs and the trip in progress detection 708 is true, the control flow 701 proceeds to the third occurrence check 710. If the third occurrence check 710 is negative, meaning less than three occurrences of the unplug event detection 704 have occurred, the control flow 701 proceeds to a log an occurrence module 711. The log an occurrence module 711 can record the first occurrence or the subsequent occurrence of the unplug event detection 704. The control flow then proceeds to the monitor vehicle function module 714 to oversee the operational status of the vehicle 202.
When the display message loose connector pin detected module 712 has been asserted, the on-board diagnostic dongle 232 can send the message 506 for the user to examine or replace the on-board diagnostic port 228 and acknowledge the action to the on-board diagnostic dongle 232. If the detection of the loose connector pin 416 persists after the user has acknowledged the change of the on-board diagnostic port 228 the on-board diagnostic dongle 232 can declare itself incompatible. The user could attempt to insert an extension cable between the on-board diagnostic port 228 and the on-board diagnostic dongle 232.
It has been discovered that the mobile compute system 100 improves the reliability for calculating the diagnostic information for the vehicle 202 by alerting the user to the detection of the loose connector pin 416. For example, the mobile compute system 100 can implement the detection of the loose connector pin 416 based on a different number of the occurrences of the unplug event detection 704. By detecting the loose connector pin 416 and alerting the user to repair the connector body 402, a more reliable and efficient record of the operation of the vehicle 202 can be achieved. The detection of the loose connector pin 416 can improve the operation of the controller area network 226 and improve the operation and safety of the vehicle 202.
