Vehicles, such as automobiles, may be equipped with an instrument panel. The instrument panel may provide the operator with useful information for operating and driving the vehicle. The instrument panel may indicate the speed of the vehicle, the revolutions-per-minute (RPM) of the vehicle's engine, a present state of the lighting, a present state of the windshield wipers, for example. The instrument panel may employ mechanical gauges, digital displays, or a combination thereof to convey information about the status of the vehicle.
Instrument panels may be embedded or placed in the dashboard of the vehicle. This ensures that the instrument panel is in a line of sight for the vehicle's driver. Thus, the vehicle's driver may view the road while safely glancing at the instrument panel to obtain useful information for aiding in the operation of the vehicle. The instrument panel's placement is static, and thus fixed in a specific location.
The gauges of the instrument panel may be implemented with mechanical pointers, or digital displays, or combinations of both. A mechanical pointer is anchored at a pivot point, and driven by a motor (for example a stepper motor) in a 360 degree fashion. Based on the current employed to drive the motor, or control signals, the motor may move the mechanical pointer in a clockwise or counter-clockwise fashion. The mechanical pointer is conventionally longer in the direction in which the mechanical pointer is pointing at.
Traditionally, instrument clusters have primarily been analog and mechanical presentations. Thus, a pointer, or other type of mechanical interface may be implemented. The mechanical presentations may interface with various electronics associated with the vehicle, and provide information via indicators and indicia to an observer of the instrument panel.
Recently, instrument clusters have become digital in their presentation. The digital presentation allows for various types of electronic information to be presented to a vehicle's operator or passenger. The digital information may reflect all the information traditionally provided via the mechanical presentations. Additionally, the digital presentation device may also serve content traditionally associated with digital provided data. The content may be news, information, streaming content, and the like. The digital presentation device may be provided with an interface, such as an external operating device. The digital presentation device may also be incorporated with various touch screen technology, such as resistive touch or capacitive touch technologies.
Various implementations of instrument clusters have employed a combination of a mechanical elements and digital presentation devices. Thus, an implementer of an instrument cluster may employ the mechanical elements in situations where a mechanical presentation is preferred (i.e. for cost based reasons or aesthetic reasons) in combination with a digital presentation device. Thus, the advantages and extra content associated with the digital presentation device may be served to a vehicle's driver or occupant, while maintaining an aesthetic associated with mechanical elements commonly employed in an instrument cluster.
A mechanically reconfigurable instrument cluster is provided. The mechanically reconfigurable instrument cluster includes a first display portion to display information of a first type, the first display portion includes a stem about the first display portion's axis driven by a motor; a second display portion to display information of a second type, the second display portion being configured to move in an inward and outward direction.

The invention is described more fully hereinafter with references to the accompanying drawings, in which exemplary embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure is thorough, and will fully convey the scope of the invention to those skilled in the art. It will be understood that for the purposes of this disclosure, “at least one of each” will be interpreted to mean any combination the enumerated elements following the respective language, including combination of multiples of the enumerated elements. For example, “at least one of X, Y, and Z” will be construed to mean X only, Y only, Z only, or any combination of two or more items X, Y, and Z (e.g. XYZ, XZ, YZ, X). Throughout the drawings and the detailed description, unless otherwise described, the same drawing reference numerals are understood to refer to the same elements, features, and structures. The relative size and depiction of these elements may be exaggerated for clarity, illustration, and convenience.
Instrument clusters have been implemented in a variety of manners and configurations. Traditionally, instrument clusters were a series of mechanical gauges or mechanical representations of information associated with the operation of a vehicle. The instrument cluster would be implemented in an orientation in which the driver or passenger of the vehicle was able to observe while operating the vehicle. A common location for the instrument cluster has been an area behind a steering wheel.
As stated in the Background section, recently, digital presentation devices have been incorporated along with instrument cluster implementations. Thus, information may be provided in a digital fashion in a manner that takes advantage of the various presentation capabilities of a digital presentation device. As such, the combination of mechanical gauges and a digital presentation device increase the techniques in which information may be provided.
However, due to the static nature of conventional instrument clusters, the presentation may not be optimized to take advantage of each medium's unique advantages. Because the mechanical gauges are shown at the same time as a digital presentation device, the digital presentation device may be obscured, or at a location not convenient to the passenger or driver of the vehicle. Thus, certain elements associated solely with a digital presentation device may not be realized.
Disclosed herein are a mechanically reconfigurable instrument cluster, and methods and systems for controlling a mechanically reconfigurable instrument cluster. The aspects disclosed herein allow for an instrument cluster to be in at least a first mode based on a preference, and mechanically reconfigure the instrument cluster when a transition from the first mode to the second mode is detected.
Thus, employing the aspects disclosed herein, a more robust instrument cluster is provided. The driver or passenger may realize a traditional instrument cluster presentation, or switch to a configuration that allows for engagement of the instrument cluster's digital presentation capabilities.
The system 100 may be incorporated or integrated with an instrument cluster 160. However, in another embodiment, the system 100 may be stored in a secondary device, such as a persistent store associated with an electronic control unit (ECU) 150 associated with a vehicle. Thus, the system 100, the instrument cluster 160, and the ECU 150 may communicate with each other via a bus 151 and a bus 152.
The ECU 150 may serve as a central processor that allows communication to/from various aspects of a vehicle 180. The vehicle 180 may communicate with various electronic modules, such as a fuel sensor 181, a speed sensor 182, an Internet connection 183, or the like. The electronic modules implemented in
The ECU 150 may propagate the commands and information from the various electronic modules associated with vehicle 180, and communicates an instruction to the instrument cluster 160 accordingly.
The instrument cluster 160 includes a first mechanical gauge 161, a second mechanical gauge 162, and a display 163. Two mechanical gauges are shown; however, one of ordinary skill in the art may implement the system 100 shown herein with one or more mechanical gauges.
The display 163 may be any sort of digital presentation device known in the art, such as a OLED, OLEV, LCD, CRT technology driven device. The display 163 may receive information from any of the electronic modules shown associated with vehicle 180. For example, in one mode, the display 163 may display information associated with the speed of the vehicle 180 (as indicated by information from the speed sensor 182). In another implementation, the display 163 may receive and display information associated with the Internet connection 183.
The instrument cluster 160 may be implemented with an actuating device 170. In certain implementations, the actuating device 170 may be an engage-able button situated on or around the instrument cluster 160. In another case, the actuating device 170 may be a graphical user interface (GUI) icon displayed via the display 163. Thus, the display 163 may be any sort of touch screen interface. The actuating device 170 is not limited to touchable interfaces, and thus, any known human machine interface (HMI) technique may be implemented along with actuating device 170.
The ECU 150 may be any sort of electronic processor (implemented in hardware, software, or a combination of both) installed in a vehicle to allow the various electrical subsystems to communicate with each other.
The mode change receiver 110 may receive a signal via bus 151 from the ECU 150 (propagated from the instrument cluster 160 via bus 152) that a mode of the instrument cluster 160 is to be changed. In another example, the system 100 may be directly in communication with the instrument cluster 160, and receive a signal over bus 153.
An implementation of system 100 may omit or additionally provide other techniques to generate a signal to change modes. For example, certain modes may be based on specific programs being run, or situations being entered to. For example, a mode may be changed based on a television show being displayed on the display 163.
The signal may be generated from an assertion of an actuating device 170. Thus, when a user pushes the actuating device 170, the signal is propagated to the system 100.
The current mode detector 120, in response to the mode change receiver 110, detects the current mode stored in register 121. Register 121 may be any sort of solid state memory device configured to store a present state of the instrument cluster 160. Alternatively, through the ECU 150 or directly via bus 153, the system 100 may poll the instrument cluster 160 for an indication of the current mode.
The new mode decider 130 decides the new mode in which to drive the instrument cluster 160 to be situated in. In one example, the new mode decider 130 toggles the mode from a first mode to a second mode based on the current mode. Thus, if the current mode is the first mode, the new mode decider 130 decides the new mode is the second mode.
In another example, the signal received may indicate that the instrument cluster 160 is to be in a specific mode. For example, if the signal is generated because an application is engaged (i.e. content is requested via the display 163), the new mode decider 140 may decide that the mode is to be a specific mode configured for content display.
The new mode transmitter 140 transmits the selected new mode to the instrument cluster 160. The instrument cluster 160 includes a mechanical driver 165 that drives the various components of the instrument cluster 160 to be situated in a specific mode. Examples of mechanically driven modes will be discussed further in the figures and embodiments disclosed herein.
