Description

Attorney Docket No RIG03-GN092-24TITLE: CONCRETE MIXER CONTROL SYSTEM FOR MESSAGING INTEGRATIONCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims the benefit and priority of U.S. Provisional Patent Application No. 63 / 713,782 filed October 30, 2024. The contents of the foregoing application are incorporated by reference herein in its entirety for all purposes.TECHNICAL FIELD

[0002] This disclosure relates to control systems for operation of concrete mixer machines and concrete mixer vehicles, and in particular, to integration of messaging relating to mixer controls and operational parameters.BACKGROUND

[0003] There is a continuing need for improvement in increasing the ease and efficiency of operations, and improving accuracy of control, of concrete mixer vehicles and similar machinery. Such concrete mixer vehicles are generally described in, for example, U.S. Patent No. 10,239,403 issued March 26, 2019, the contents of which are incorporated herein by reference for all purposes.

[0004] Owners, contractors, managers, and fleet managers (hereinafter, collectively called “owners” for convenience) of concrete mixer vehicles use telecommunications and informatics technologies systems to monitor, collect, transmit, and employ data about the vehicles and their operations. Typically, the telecommunications and informatics technologies systems connect vehicles to a central platform for real-time tracking and analysis. A vehicle’s onboard electronic devices may include various sensors and GPS units installed in the truck that collect and transmit data on concrete mixer operations such as mixer drum status, mixer drum operational conditions, truck location, speed, fuel consumption, engine performance, braking, and more. A data communication network is employed to transmit the truck’s collected data via cellular, satellite, or Wi-Fi networks to a cloud-based or centralized system. A third party’s platform, such as a third- party vendor’s telematics platform, utilizes software that aggregates and analyzes the inbound data, and generates signals and commands based on the inbound data. The generated signals and commands also may be centrally generated by the vendor’s platform independent of the inbound data; for example, the vendor’s platform may independently generate a software update to be communicated on-air back to the owner and to the truck’s onboard device. TheAttorney Docket No RIG03-GN092-24 telecommunications system then may be employed by the vendor’s platform to convey back to the owners, and to the onboard devices, outbound data, signals, and commands relating to operations of the vehicles and their components. The outbound data, signals, and commands issued by a vendor thus may be communicated to owners through the owner’s computer system located in owner facilities, and to drivers via the onboard electronic devices, which communicate to the drivers via displays, signals, and other communication means in the truck.

[0005] A number of problems arise for owners in connection with the use of the foregoing systems. Often, an owner will be operating a number of different brands, models, and types of concrete mixer vehicles, each having different components, features, and functions. As a result, the outbound data described above that is sent out by vendors might be relevant only to some of the owner’s trucks, and not to other trucks. Another problem arises in that an owner might subscribe to a number of different third-party vendor platforms. The owner may have a need to control flow of inbound data and outbound commands and signals that are communicated among the owner, the various vendor platforms, and the vehicle, based on the owner’s information security needs. SUMMARY OF THE DISCLOSURE

[0006] The present disclosure includes an improved method, vehicle, device, system, and controller system for concrete mixer applications. In particular, an improved control system is provided for control of system messaging.

[0007] This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used as an aid in limiting the scope of the claimed subject matter. Further examples, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and drawings.BRIEF DESCRIPTION OF THE DRAWINGS

[0008] FIG. l is a diagram illustrating a method and a system for concrete mixer vehicle messaging control according to an exemplary embodiment of the invention.

[0009] FIG. 2 is a diagram depicting a control system for concrete mixer vehicle messaging control according to an exemplary embodiment of the invention.DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

[0010] For the purposes of clearly describing illustrative embodiments of the present disclosure, the manner, and process of making and using the same, and to enable the practice, making and use of the same, reference will now be made to certain examples, including those illustrated in theAttorney Docket No RIG03-GN092-24 figures, and specific language will be used to describe the same. It shall nevertheless be understood that no limitation of the scope of the invention is thereby created, and that the invention includes and protects such alterations, modifications, and further applications of the examples as would occur to one skilled in the art.

[0011] Some current mixer control systems have internal messaging that is not set up for integration. The internal messaging could change based on component selection and variables not controlled by the system designers. However, the customers of the system designers find value in having access to messages, but likely have multiple variations of the same system. Without a unified messaging system, integration is extremely difficult, if not impossible. Additionally, some customers may desire to turn on certain messages and turn off other messages based on the system with which they are integrating, due to information security reasons.

[0012] Provided in this disclosure is an improved method and system for control of electronic messages sent between an end user of a concrete mixer truck and a service provider. As used herein, an end user may be a concrete mixer owner or manager that owns or manages a number of concrete mixer trucks. The number of trucks may include a fleet of trucks. The fleet of trucks may be of different brands, makes, models, and model years. In another embodiment, an end user may be the driver of the truck, or a worker that operates the concrete mixer truck. The differences in trucks and in fleets creates a special problem for a fleet manager and for a driver or operator, in that many different drivers or operators may be assigned to work with different trucks on different days, and thus the drivers or operators may be unfamiliar with the outbound messages received from service providers, creating confusion and inability to address matters raised in the outbound messages.

[0013] End users frequently engage service providers for their vehicles to provide services that aid in operation of the truck. The services may include inbound and outbound informational services provided by wired or wireless electronic communications systems, platforms, or networks. The informational services may be provided by vendors that sell the informational services to the end users. The services may include aids to operation of the end users’ vehicles, such as providing and accepting data related to the vehicle and its operations. Some examples of specific services may include: GPS tracking of the truck or vehicle; real-time location monitoring of the truck or for route optimization and security; driver behavior monitoring to track operational parameters like a driver’s harsh braking, acceleration, and idling, to improveAttorney Docket No RIG03-GN092-24 safety and efficiency; maintenance alerts relating to the vehicle; predictive maintenance monitoring based on engine diagnostics and usage patterns; fuel management, to help monitor a vehicle’s fuel consumption and detect anomalies like theft or inefficiency; and regulatory compliance to help the end user meet and prove compliance with regulatory, labor, or health and welfare requirements such as monitoring the maximum hours of service that a driver may perform in a working shift.

[0014] As schematically illustrated in FIG. 1, disclosed is a step of providing a communication bus 10 accessible by the end user and by at least one service provider. A concrete mixer manufacturer or seller may provide to its customers, the end users, a central communication bus 10 accessible to both end users and service providers. The end user’s electronic system 14 may be provided with such access. Disclosed is a step of providing to the end user a selection of messaging options, represented by the step and feature 12 of FIG. 1. The provider of the bus 10 may offer, via the communication bus, a selection of messaging options in the form of a menu or list wherein the end user may select which service provider’s messages should be received and conveyed to the end user. The selection service offered by the communication bus enables the end user to screen and fdter the outbound messages to be received. The filtering conducted by the end user may be based on the end user’s need to eliminate messages that are irrelevant to a selected end user, a selected driver, a selected fleet, a selected make, model, brand, model year, or components of a selected truck, a selected location of the truck, or a selected span of time for receipt of such outbound messages.

[0015] Disclosed is a step wherein, based on the messaging options selected by the end user, the communication bus 10 is operated to limit messages sent to the at least one service provider. The service provider may access the bus system via the service provider’s electronic system 22. For example, for security or privacy reasons, the messaging options selected by the end user may be entered to avoid needless disclosure of a location of a truck.

[0016] In embodiments, a step a disclosed of operating the communication bus 10 to limit messages sent to the end user. For example, to avoid confusion or dangerous conditions that may arise due to display of inapplicable or irrelevant messages to an end user, the communication bus operator may operate the communication bus 10 to enter commands to limit selected messages from being sent to an end user.Attorney Docket No RIG03-GN092-24

[0017] In embodiments, a step is disclosed of providing to at least one service provider a selection of messaging options that is generated based on the messaging options selected by the end user. The step and feature of providing to the end user a selection of messaging options, represented by the step and feature 20 of FIG. 1. For example, after an end user selects from a menu of options to block any messages from a selected service provider, then the communication bus 10 may be operated to provide to the service provider a menu for selecting only those messaging options that already have been specifically selected by the end user. Thus, the service provider’s menu has been tailored to the particular end user’s preferences.

[0018] In embodiments, there is provided a step of making the communication bus 10 accessible to an end user that is an operator who is not a driver of the vehicle, via a remote electronic system separate from an onboard electronic system of the vehicle, and the selection of messaging options is made via the remote electronic system. For example, as illustrated in FIG. 1, an end user’s electronic system 14 may include two accessing systems, one being an onboard electronic system 16 provided onboard a truck, and one being a remote electronic system 18 of the end user. In this manner, in examples, a fleet owner or manager may operate its own remote electronic system 18, such as a remote stationary computer system 18 located at a fleet manager’s headquarters. In an example, the remote computer system of a fleet manager is separate from the onboard electronic system 16 of the vehicle in question, which may transmit and receive messages remotely from both the bus 10 and the remote computer system 18. Via wired and wireless communications networks or platforms, the fleet manager may access the communication bus 10 using the fleet manager’s remote computer system 18. The fleet manager may make its selection of messaging options via electronic communications between the remote computer system 18 and the communication bus 10. In this manner, the fleet manager may fdter and control the messaging received by the truck driver in the onboard system 16.

[0019] In embodiments, there is provided a step of making the communication bus accessible by at least two service providers. At times, a particular service provider engaged by a fleet manager is not relevant to one or more of the trucks in the manager’s fleet. The end user, in this example, a truck owner or fleet manager, may make its selection of messaging options to be accepted based on which service provider, or which plurality of service providers, is chosen to be enabled to send outbound messages relating to a selected fleet, truck, or driver. In this manner, the end user is enabled to screen the incoming messages based on the identity of the service provider.Attorney Docket No RIG03-GN092-24

[0020] In exemplary configurations according to this disclosure, there may be provided a concrete mixer with a drum configured to mix concrete, the concrete mixer comprising an onboard electronic control system. The onboard system may include a display. The display may be configured to indicate status conditions, inbound messages from service providers, and various other informational messages to the driver. In exemplary configurations, the onboard control system may be configured to selectively publish information and status about both the concrete mixer control system and the chassis that it was installed on. In exemplary configurations, the onboard control system has a user definable messaging system that allows each end user, including the end user examples of a driver, an owner, or a fleet manager, to customize the information delivered to the service providers. The service providers may be third party integrators that the end user engages for certain services such as truck tracking, tire inflation, driver monitoring, and similar services.

[0021] Disclosed is an improved a control system that allows an end user to turn messaging on and off for various services and is protected by the control system, such that the service providers, which may be third party vendors, are not able to change the system messaging independently, and thus risk breaching the end user’s security in the end user’s choices of selected information to be conveyed to or transmitted from the concrete mixer control system’s communication system. The control system may comprise a central communication bus. In embodiments, a control system may use password and / or encryption protection to prevent end users, such as a driver of a truck, from modifying the data being transmitted to the third-party vendors.

[0022] Disclosed is an improved control system wherein a concrete mixer control system is provided that comprises its own telematics system which would allow over the air communications, software updates, remote diagnostics, and similar services in addition to feeding various third-party vendor systems information as may be required. End users may select various messages and messaging settings that keep the control system information private from the third- party vendors unless the end user, such as a fleet manager, selects to share such information.

[0023] Disclosed herein is a configuration according to embodiments wherein a control system will automatically / programmatically generate a database container file (dbc) based on the enabled messaging parameters. This feature improves ability to integrate with various third-party service providers based on end user preference. This feature adds additional security for each end user, as the system only will publish or provide data on a data link between the communication bus systemAttorney Docket No RIG03-GN092-24 and the third-party vendor’s system, the information that the end user selected to supply to the service provider. In embodiments, such information limitation may be protected by password, multi-factor authorization, or other security devices or methods.
