The present invention relates generally to straddle vehicles, especially motorcycles. Particularly, it relates to a bus topology expandable to accommodate one or more peripheral devices distributed about the straddle vehicle. In one aspect, a user interface module controls the peripheral devices from a single location, especially a handlebar. In another aspect, the topology includes hub controllers and bus trunks operating according to a desired protocol, such as a controller area network (CAN) protocol. Peripheral devices include radios, music players, radar detectors, cell phones and the like.
Straddle vehicles generally include motorcycles, all-terrain vehicles, jet-skis, snowmobiles and the like. In recent years, manufacturers and retailers have increasingly added peripheral devices to the vehicles to meet growing consumer demands and/or provide features and functionality to gain advantage over competitors. For example, today's motorcycles are regularly offered with robust radios having multi-frequency capabilities whereas years ago they did not even contemplate radios. The same is true of radar detectors, music players and other similar peripheral devices.
Problematically, control over each of these devices requires users to interface directly with the switches of the actual device. Because devices can have great quantities of switches and varieties, users sometimes find operation difficult, especially while riding the vehicle. Safety may also be implicated if the devices are distributed about the vehicle chassis in positions where users need to divert their attention from the safe operation of the vehicle. In addition, as users desire to increase the number of peripheral devices on their vehicles, modifications to the vehicle require additional dedicated wiring harnesses and dedicated control. Moreover, straddle vehicles often carry two or more riders, each having helmets including speakers for listening to the peripheral devices as well as intercoms to communicate between the riders. The wiring harnesses and control must then also contemplate multiple-rider scenarios.
In an attempt to overcome the foregoing problems, some prior art systems connect multiple peripheral devices into “all-in-one” structures. For example, the AudioBoss model AB-Im includes speakers, intercoms and a variety of peripheral devices, such as an MP3 player, a radar detector, a cell phone and a 2-way radio, in an integrated intercom structure. Although each rider can hear the peripheral device presently in use, users must still control the device (e.g., volume control, frequency or channel switches) via the buttons, switches and knobs of the control panel of the actual device. Thus, problems remain.
Accordingly, a need exists in the straddle vehicle arts for easily operating one or more peripheral devices, despite the devices having numerosity in their control panel knobs, switches and buttons. This need further includes an ability to robustly accommodate peripheral devices added to the vehicle upon user demand, even if the peripheral devices are generally incompatible. An example of incompatible devices includes a radar detector and a cell phone.
The above-mentioned and other problems become solved by applying the principles and teachings associated with the hereinafter described bus topology for peripheral devices of a straddle vehicle, including an expandable topology to accommodate peripheral devices added after initial configuration. Single point control therefor is also provided.
In one aspect, the topology includes a main hub controller and/or secondary hub controllers. Each controller attaches to a bus trunk and one or more peripheral devices. The main hub controller can also interface with additional bus trunks to accommodate additional peripheral devices added to the straddle vehicle by the user. Further, a user interface module connects to the main hub controller. Users initiate commands with the module for controlling the peripheral devices and the main hub controller responds accordingly. Preferably, the controller(s), bus trunk(s), peripheral device(s) and user interface module operate according to a controller area network (CAN) protocol. CAN protocol typically conforms to ISO 11898 for serial data communication. Peripheral devices include cell phones, CD players, MP3 players, radar detectors and radios, such as AM, FM, XM, WB, GMRS or CB. Methods for control thereof are also described.
In another aspect, the user interface module controls one or more peripheral devices from a single point of control, especially a handlebar. The module has a four-way rocker switch, a preset switch and a mode switch. Together, the switches accommodate a wide-range of user selections for a vastly varying number of peripheral devices. The switches reside on the module beneath the handlebar where a user can easily manipulate them with a thumb while still grasping the handlebar with one or more fingers of the same hand.
These and other embodiments, aspects, advantages and features of the present invention will be set forth in the description which follows, and in part will become apparent to those of ordinary skill in the art by reference to the following description of the invention and referenced drawings or by practice of the invention. The aspects, advantages, and features of the invention are realized and attained by means of the instrumentalities, procedures, and combinations particularly pointed out in the appended claims.
The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention and together with the description serve to explain certain principles of the invention. In the drawings:
Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.
In the following detailed description of the preferred embodiments, 10 reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that process or other changes may be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense and the scope of the present invention is defined only by the appended claims and their equivalents. In accordance therewith, a bus topology expandable to meet differing varieties and quantities of peripheral devices distributed about a straddle vehicle is hereinafter described. The topology also includes an option for user to control the one or more peripheral devices from a single location on the straddle vehicle and to do so with robust functionality from a limited number of ergonomically positioned switches.
As used herein, straddle vehicles include, but are not limited to, motorcycles, all-terrain vehicles, jet-skis, snowmobiles and the like. Since these are well known, they will not be further described herein in detail. Some of the more popular manufacturers of straddle vehicles include Harley Davidson, Honda, Yamaha, BMW, Kawasaki, Polaris, and Ski-doo. Peripheral devices of the invention include, but are not limited to, cell phones, CD players, MP3 players, radar detectors, global positioning or other navigation devices and radios, such as AM, FM, XM, WB, GMRS or CB. They even include user interface module(s) for operating one or more of the other peripheral devices.
As further used herein, “topology” refers to a physical and logical/electrical layout of components. A bus, on the other hand, refers to the near-simultaneous communication of information over groups of wires to one or more peripheral devices. As is typical in a bus, all peripheral devices continually “listen” or “watch” for information directed or addressed thereto. Then, upon receipt of such information, they act or respond according to the command therein. Broadly stated, “information” includes, but is not limited to, one or more of data, commands, or addresses. Some advantages of bus topologies over the prior art's use of dedicated systems includes: the use of relatively little cable/wiring for the varieties and quantities of peripheral devices; easy expansion to accommodate additional peripheral devices; simplicity and flexibility.
With reference to
In one embodiment, the bus trunk, controllers and peripheral devices operate according to the controller area network (CAN) protocol defined presently as ISO standard 11898 for serial data communication. At first, CAN was developed for the automotive industry but today finds widespread use in other disciplines, such as industrial automation. The CAN protocol has four general message types including the data frame, the remote frame, the error frame and the overload frame to communicate information along the bus trunk. For a complete description of the various nuances, species and particulars of the CAN protocol, including the number of bits, the arrangement of message identifiers, the timing, the priority, bus speeds, bus termination, cabling and connector requirements, etc., the present invention herein incorporates, by reference, the entirety of the ISO 11898 standard defined by the International Organization for Standardization. However, the present invention is not limited to this protocol and other known or hereinafter invented protocols or rules for governing the format and timing exchange of bus information are embraced herein. Other embodiments, for example, contemplate utilization of RS-232 or J1850 protocols.
With more specificity,
The secondary hubs 102 have generally the same circuitry/arrangement and behave the same as the main hub controller except that only message traffic of attendant peripheral devices travels there through. Physically, and unlike the main hub controller which can connect to any number of bus trunks, the secondary hub controllers only connect to single bus trunks. In this instance, secondary hub controller 102-2 connects to bus trunk 104-1 and secondary hub controller 102-3 connects to bus trunk 104-2. Meanwhile, the main hub controller 102-1 connects to two bus trunks 104-1, and 104-2. As skilled artisans will recognize, the resulting topology resembles a star topology where all information or message traffic passes via the main hub controller. The advantage of a star topology includes the ability to better troubleshoot or isolate failures between branches emanating from the main hub.

As another example of a bus topology for accommodating peripheral devices of a straddle vehicle, consider the bus topology 300 of
In contrast,
For example,
In
In function, the main hub controller's components include a controller 706, a bus driver 708, an audio processor 710, a power conditioner 712, one or more amplifiers 714 and other functionality 716. In one embodiment, the controller 706 includes a commercially available microprocessor, such as a Motorola brand 9S12 microprocessor. The bus driver includes components necessary to drive the bus, such as a CAN driver in the event the protocol selected is ISO 11898. The audio processing 710 includes a Phillips brand audio processor operable according to I2C functionality. The power conditioning 712 is circuitry that has an input of +12 vdc directly from the battery of the straddle vehicle. The output is a voltage of five, eight or twelve volts or other to run the various components of the topology. Since the input voltage is generally a very dirty signal, circuitry also exists to make the outputs well-regulated, clean and steady. The amplifiers 714 are circuits to make weak signals stronger and skilled artisans readily understand them. The other functionality 716 includes miscellaneous components such as those necessary to drive or interface with speakers, auxiliary devices, microphones, filters, cooling devices (e.g., fans) or the like. It also contemplates specific electrical components, such as capacitors, resistors, transistors, etc. to make the components operate properly with one another. Skilled artisans are well educated in this regard and no further discussion is necessary. Naturally, the user interface 702 and peripheral device 704 may also have their own microprocessors or controllers therein, depending upon the actual device implemented.
In
In a preferred embodiment, the user interface module includes a display 830 and a plurality of switches 832, 834, 836. The display 830 can be an LCD panel that displays user's selections in response to their manipulation of the switches. In other embodiments, the display avoids or compliments LCD technology with LED's, plasma technology or other known or hereafter invented technology. The function of the display is to provide a visual indication to the user regarding the control of the one or more peripheral devices. As illustrated, the display indicates FM 103.1 which corresponds to a scenario in which a peripheral device under control (e.g. FM radio) is presently tuned at a frequency of 103.1.
The switches include a preset switch 832, a four-way rocker switch 834 and a mode switch 836. In phantom, one or more fingers of a user's hand 850 can grasp or hold the handlebar 810 while a thumb can manipulate any of the switches. As is often found on motorcycles, for example, the preset and mode switches are of the press-and-hold or press-and-release variety. The four-way rocker switch 834, on the other hand, is of the joystick variety or of four discrete positions dictated by pressing one of the arrows thereon. In combination, these switches represent a relative advance in the arts. As will be seen in
In physical regard, the display 830 mounts generally in-line with the handlebar so users can easily see its readout. The switches, however, mount beneath the handlebar. They also mount generally offset from a terminal end 862 of the handgrip 860 in the direction of arrow A. Because the rocker switch 834 has a generally larger surface-area compared to the preset and mode switches, it fits between the preset and the mode switches. In this manner, users can readily locate each of the switches during use without necessarily needing to look at them.
In function, the preset switch 832 generally adjusts one or more peripheral devices to a preset condition. The preset condition can represent a radio frequency, such as FM 103.1 as shown. The mode switch generally changes control from one of the peripheral devices to another. The rocker switch generally increases or decreases volume, bass, treble or other of a peripheral device under control, such as by manipulating the up or down arrows. With the left and right arrows, a user can switch between various functionality of the peripheral device under control. For example, if the peripheral device embodies an FM radio, the left and right arrows may allow for manually tuning the frequency to a higher a lower-frequency radio station.
With reference to
In
Press-and-release operation of the mode switch will cause the source of the radio to sequentially cycle between FM, AM and an auxiliary input. These states are given as 918, 920 and 922 respectively. When switched to AM, the default changes to AM 870. The auxiliary input can be any of the fore-mentioned peripheral devices.
Press-and-hold of the mode switch will sequentially cause the cycle of Bass 924, Treble 926 and Volume 912 to occur. Once in these states, further pressing of the up/down arrows of the rocker switch will either increase or decrease the bass, the treble or the volume as indicated by the up/down arrows to the right side of these states.
Press-and-release operation of the preset switch 928 will tune the radio to various preset radio stations. Conversely, press-and-hold operation of the preset switch will enable the user to preset the stations 930 or to store the same 932. The number of presets will vary according to preference.
In
Pressing of the preset switch will enable a user to transmit, state 1016. Preferably, such occurs via a microphone that interfaces with the main hub controller via the other functionality block 716,
Press-and-release of the mode switch sequentially cycles the GMRS radio between code adjust 1018, VOX 1020, rear volume adjust 1022 and channel adjust 1014. Conversely, press-and-hold of the mode switch changes the monitor 1024.
