Description

PRIORITY

This application is a continuation of U.S. Non-Provisional patent application Ser. No. 11/737,461, entitled “Wirelessly Controlled Motorized Vehicle System,” filed Apr. 19, 2007, which is incorporated herein by reference in its entirety, and which claims priority from the disclosure of U.S. Provisional Patent Application Ser. No. 60/793,312, entitled “Enabling Wireless Control of Various Subsystems in Motorcycles,” filed Apr. 19, 2006, which is incorporated by reference herein in its entirety.

BACKGROUND

Conventional motorized vehicles typically include a plurality of mechanical subsystems and various devices configured to control and/or monitor those subsystems. In general, the controls and gauges are physically connected to the mechanical subsystem they are associated with via a cable or wire. For example, in a conventional motorcycle, the clutch handle is physically connected to the clutch assembly via a clutch cable. Similarly, in a conventional motorcycle, the throttle handle is connected to the carburetor via a throttle cable. In addition, the gauges on a conventional motorcycle, such as the speedometer, the tachometer, typically include a control wire connecting the sensing portion of the gauge positioned proximate to a mechanical subsystem to the gauge display viewed by the rider. Other conventional motorized vehicles, such as riding lawn mowers and push lawn mowers, have similar physical connections between the controls/gauges and the associated subsystems.
One result of the physical connections required by most conventional motorized vehicles is that the cable and/or wire may be susceptible to increased damage if it is left exposed during use. Therefore, motorized vehicles are typically designed to provide a housing for the cable and/or wire as it runs from the control to the appropriate subsystem. For example, in a conventional motorcycle, the handlebars are configured in a continuous, hollow, tubular shape to provide a protective pathway through which to run the clutch cable and throttle cable from the controls to the clutch assembly and carburetor, respectively. Similarly, the control wires connecting the sensing portion of the gauge to the gauge displays may also be threaded through the handlebars to prevent damage.
Removing the physical connections between a control and a subsystem or between a gauge and a display may provide fabricators with the freedom to design new motorized vehicles, for example, new motorcycles with new types of handlebars that are not required to provide housing for cables and/or wires. Providing increased freedom in the fabrication of handlebars may enable the development of more aesthetically pleasing, aerodynamic, ergonomically improved, and/or lighter weight handlebars. Finally, removing the physical connections between a control and a subsystem or between a gauge and a display may provide increased options for customization of motorized vehicles. For example, users may choose completely unique components rather than being required to choose from a list of stock components. Therefore, it may be desirable to provide a wirelessly controlled system to allow a user to control and/or monitor various subsystems.

The following description should not be used to limit the scope of the present invention. Other examples, features, aspects, embodiments, and advantages of the invention will become apparent to those skilled in the art from the following description, which includes by way of illustration, one embodiment contemplated for carrying out the invention. As will be realized, the invention is capable of other different and obvious aspects, all without departing from the invention. Accordingly, the drawings and descriptions should be regarded as illustrative in nature and not restrictive. It should therefore be understood that the inventors contemplate a variety of embodiments that are not explicitly disclosed herein.
FIG. 1 depicts a schematic view of an exemplary wirelessly controlled motorized vehicle system (10). As shown, the system (10) comprises a motorized vehicle (20) and a wireless communications system (50). It will be appreciated that the motorized vehicle (20) may comprise a motorcycle, a lawn mower, or any other suitable motorized vehicle. In the present example, the motorized vehicle (20) comprises a controller (30) and a drive system (40). As used throughout this application, the term “controller” refers to a device or assembly configured to receive input from the user regarding the operation of a portion of the drive system. A controller may function as and/or replace one or more of the following conventional motorcycle controls: a clutch handle, a throttle handle, a hand shifter, or any other similar conventional control. In addition, as used throughout this application, the term “drive system” refers to one or more systems or components of a motorized vehicle configured to enable locomotion of the motorized vehicle. In this example, the drive system (40) comprises a portion of the drive system (42). The portion of the drive system (42) may comprise one or more of the systems or components configured to enable locomotion of the motorized vehicle.
As shown in FIG. 1, the controller (30) is in communication with the portion of the drive system (42) via the wireless communications system (50), which comprises a transmitter (52) and a receiver (54). In this version, the transmitter (52) is associated with the controller (30) and the receiver (54) is associated with the portion of the drive system (42). Although the system (10) shown in FIG. 1 includes one controller (30) and one portion of the drive system (42), it will be appreciated that a system may comprise any suitable number of controllers and portions of the drive system. It will further be appreciated that the number of controllers may correspond to the number of portions of the drive system, but this is not required.
As shown, the controller (30) is configured to receive a command (60) from a user. It will be appreciated that the controller (30) may comprise a handgrip assembly, as shown in FIG. 3, or any other suitable device. The command (60) may comprise an instruction to disengage the clutch, increase the throttle, change gears, or any other suitable instruction. The command (60) may be communicated to the controller (30) by physically manipulating the controller (30). The controller (30) may be integral with the motorized vehicle (20). A processing unit (not shown), such as a microprocessor, a microcontroller, a parallax chip, or any other suitable device, may be used to facilitate communication of the command (60) from the controller (30) to the transmitter (52). In particular, the processing unit (not shown) may comprise an 8-bit PIC based microcontroller, but this is not required. It will be appreciated that the controller (30) and the wireless communication system (50) may be powered by a battery, such as a button cell battery, or any other suitable power source or device.
FIG. 2 depicts a schematic view of an exemplary embodiment of a controller (130). As shown, the controller (130) comprises a force detection device (132) and a processing unit (134). The force detection device (132) may be configured to detect pressure applied as the user inputs a command (160) by manipulating the controller (130). The force detection device (132) may comprise a pressure sensitive molecular microswitch, a thin film force sensor, or any other suitable device. The processing unit (134) may be configured to facilitate communication between the force detection device (132) and a transmitter (152). In the present example, the processing unit (134) is configured to receive an output from the force detection device (132) and communicate that output to the transmitter (152). The processing unit (134) may comprise a microprocessor, a microcontroller, a parallax chip, or any other suitable device. In particular, the processing unit (134) may comprise an 8-bit PIC based microcontroller, but this is not required. A replacement protocol may be programmed into the processing unit (134) to facilitate the replacement of damaged components, such as transmitters, receivers, or processing units, which may comprise computer chips, by enabling the pairing of the replacement component with the proper existing components. The processing unit (134) may be configured to communicate a code along with the numerical value to the transmitter (152). The code may be used to verify the signal and/or to identify the particular controller (130) from which the signal originated. It will be appreciated that the force detection device (132) and the processing unit (134) may be powered by a battery, such as a button cell battery, or any other suitable power source or device.
Although the embodiment of a controller shown in FIG. 2 includes a processing unit (134), it will be appreciated that a processing unit is not required. For example, a controller may comprise a force detection device. In such an embodiment, the force detection device may be configured to communicate directly with the transmitter. The output from the force detection device may then be converted to a numerical value by the transmitter and communicated to a receiver associated with a portion of the drive system.
FIG. 3 depicts an alternate embodiment of a controller (230) comprising a hand grip assembly (240) attached to a handlebar frame (220). The handgrip assembly (240) may be integral with the handlebar frame (220) or removably attached to the handlebar frame (220). The hand grip assembly (240) may be attached to the handlebar frame (220) with set screws, bolts, welds, or any other suitable device or method. As shown in FIG. 3, the handgrip assembly (240) comprises an upper portion (250) and a lower portion (260). In the present example, upper portion (250) comprises a rounded outer surface (252) and a pressure panel (254).
Similarly, as shown, the lower portion (260) comprises a rounded outer surface (262). In this version, the controller (230) is positioned such that a user may grasp the handgrip assembly (240) while steering the motorized vehicle. A wirelessly controlled motorized vehicle system may comprise two handgrip assemblies positioned on opposite ends of the handlebar frame, where one handgrip assembly is associated with the clutch and the other handgrip assembly is associated with the throttle, but this is not required.
FIGS. 4-5 depict exemplary components of the handgrip assembly (240). In this version, in addition to the rounded outer surface (252) and the pressure panel (254), the upper portion (250) comprises a flattened inner surface (253), a force detection device (255), an aperture (256), and a cavity (258). As shown in FIG. 5, the force detection device (255) is inserted through the aperture (256) such that a sensor portion (257) is inserted into a recess (259) and positioned proximate to the pressure panel (254) when the pressure panel (254) is positioned within recess (259). Thereby, the pressure panel (254) is able to contact the sensor portion (257) when a user applies pressure to the pressure panel (254). The force detection device (255) may comprise a pressure sensitive molecular microswitch, a thin film force detector, or any other suitable device. In the present example, the upper portion (250) also comprises dampening material (270) positioned within the cavity (258) and configured to reduce vibrations within the cavity (258). The dampening material (270) may be surface mounted within cavity (258) by any suitable device or method.
As shown in FIG. 4, in addition to the rounded outer surface (262), the lower portion (260) comprises a flattened inner surface (263), a trough (264), a component support member (265), a processing unit (266), a power source (267) and a transmitter (268). The trough (264) may be formed within the lower portion (260) by milling or any other suitable process. In the illustrated version, the processing unit (266), the power source (267) and the transmitter (268) are attached to the component support member (265), which is then positioned within the trough (264) and attached to the lower portion (260). The processing unit (266) may comprise a microprocessor, a microcontroller, a parallax chip, or any other suitable device. In particular, the processing unit (266) may comprise an 8-bit PIC based microcontroller, but this is not required. Additionally, the transmitter (268) may comprise a BLUETOOTH™ transceiver, a ZIGBEE™ transceiver, or any other suitable device. The power source (267) may be configured to provide power to the processing unit (266) and the transmitter (268). The power source (267) may comprise a button cell battery or any other suitable device.
As shown in FIG. 3, the handgrip assembly (240) may be assembled by connecting the force detection device (255) to the processing unit (266). Additionally, the upper portion (250) may be positioned such that the flattened inner surface (253) is proximate to a first surface (222) of the handlebar frame (220), and the lower portion (260) may be positioned such that the flattened inner surface (263) is proximate to a second surface (224) of the handlebar frame (220). During assembly, the cavity (258) may be positioned above the component support member (265) to provide a housing for the processing unit (266) and the transmitter (268).
As described above, dampening material (270) may be attached to the upper portion (250) within the cavity (258) to help reduce damage to the processing unit (266) and the transmitter (268) once they are positioned within the cavity (258). The dampening material may comprise static resistant rubber foam or any other suitable material. The dampening material (270) may help reduce damage by being configured to absorb vibrations, thereby reducing the amount of vibrations that reach the processing unit (266) and the transmitter (266). In addition, the dampening material (270) may be configured to provide additional support to stabilize the processing unit (266) and the transmitter (268). Finally, the dampening material may be configured to block any residual or unexpected electrical current flowing through the handlebar frame (220), thereby further protecting the processing unit (266) and the transmitter (268).
The sensitivity of the force detection device (255) may be calibrated based on the characteristics of an individual user, thereby enabling the user to determine the magnitude of the response in the drive system resulting from applying a specified amount of pressure to the pressure panel (254). For example, the calibration may be based on the user's preferences, the user's physical characteristics, such as weight or strength, the user's skill level in operating the motorized vehicle, or any other suitable characteristic. The force detection device (955) may be calibrated using standard calibration techniques well known within in the art. For example, as pressure is applied to a force detection device, it registers a series of reference points corresponding to the amount of pressure applied. Those reference points are then communicated to a mechanical device, such as the manipulation device (370) described and shown below. The reference points then instruct the mechanical device how far to move or rotate. Compared to conventional controls connected by control cables or control wires, this calibration may provide increased responsiveness between the controller (230) and the associated mechanical component. In addition, the calibration may improve the safety of users by providing the user with increased control over the motorized vehicle.
In one embodiment, a user may input an instruction to increase throttle, disengage the clutch, shift gears, or any other suitable instruction by applying pressure to the pressure panel (254). The force detection device (255) may be configured as a RC time constant circuit. In this version, the force detection device (255) may register the level of pressure applied by the user and communicate that information to the processing unit (266). In this example, the processing unit is configured to receive the RC time constant output from the force detection device (255) and convert the output into a numerical value. The numerical value may then be communicated to the transmitter (268) and, ultimately, wirelessly communicated to the throttle, the clutch, the transmission or any other suitable portion of the drive system.
Returning now to FIG. 1, the wireless communications system (50) comprises a transmitter (52) and a receiver (54). In this version, the transmitter (52) is in communication with the controller (30), and the transmitter (52) receives the command (60) from the controller (30). In the present example, the receiver (54) is associated with the portion of the drive system (42). As shown, the transmitter (52) is configured to wirelessly communicate the command (60) to the receiver (54). Once wirelessly communicated to the receiver (54), the command (60) is then communicated to the portion of the drive system (42).
The wireless communications system (50) may be configured to communicate via at least one of BLUETOOTH™ protocol, ZIGBEE™ protocol, any other wireless communication protocols operating at a frequency above 2.4 GHz or any other suitable technology or protocol configured to wirelessly communicate signals. It will be appreciated that the transmitter (52) may comprise a BLUETOOTH™ transceiver, a ZIGBEE™ transceiver or any other suitable device. It will also be appreciated that the receiver (54) may comprise a BLUETOOTH™ transceiver, a ZIGBEE™ transceiver or any other suitable device. In this example, the type of transmitter (52) corresponds to the type of receiver (54) such that the transmitter (52) and receiver (54) can communicate with each other. It will be appreciated that the transmitter (52) and the receiver (54) may be integral with the motorized vehicle (20). By way of example only, the transmitter (52) may be embedded within the controller (30), as shown in FIGS. 3-4, positioned within a container mounted to the motorized vehicle, such as the compartment (950) shown in FIG. 14 b, mounted to the frame of the motorized vehicle, or any other suitable location. Similarly, by way of example only the receiver (54) may be embedded within the drive system (40), positioned within a container mounted to the motorized vehicle, such as the compartment (950) shown in FIG. 14 b, mounted to the frame of the motorized vehicle, or in any other suitable location. It will be appreciated that the transmitter (52) and the receiver (54) may be powered by a battery, such as a button cell battery, or any other suitable power source or device.
As shown in FIG. 1, the wireless communications system (50) comprises one transmitter (52) and one receiver (54). In this example, the transmitter (52) and the receiver (54) are configured as a pair, whereby the transmitter (52) and the receiver (54) are coded to detect and transmit signals to each other at a specified bandwidth. The bandwidth may be determined by the particular protocol being used by the wireless communications system (50). It will be appreciated that, in such an embodiment, the transmitter (52) and the receiver (54) are in constant communication and do not break signal once they are activated. However, it will also be appreciated that the wireless communications system may comprise any suitable number of transmitters and any suitable number of receivers. It will further be appreciated that the number of transmitters may correspond to the number of controllers, and the number of receivers may correspond to the number of transmitters, however this is not required. For example, a single transmitter may be configured to communicate with multiple receivers, or a single receiver may be configured to communicate with multiple transmitters. In addition, it will be appreciated that the number of receivers may correspond to the number of portions of the drive system; however, this is not required.
As shown in FIG. 1, the motorized vehicle (20) comprises a drive system (40) and a portion of the drive system (42). It will be appreciated that the portion of the drive system (42) may comprise one or more of the systems or components comprising the drive system (40), such as an engine, a transmission, a clutch assembly, a clutch plate, a throttle system, a throttle plate, an ignition system, a starter, or any other suitable system or component. In the present example, the portion of the drive system (42) is in communication with the wireless communications system (50) via the receiver (54). Similar to the communication between the controller (30) and the transmitter (52) described above, a processing unit (not shown), such as a microprocessor, a microcontroller, a parallax chip, or any other suitable device, may be used to facilitate communication of the command (60) from the receiver (54) to the portion of the drive system (42). In particular, the processing unit (not shown) may comprise an 8-bit PIC based microcontroller, but this is not required. In addition, a processing unit (not shown) may also be configured to use a code communicated with the command (60), as described above, to verify the signal containing the command (60) and/or identify the particular transmitter (52) or controller (30) from which the command (60) originated. If a processing unit (not shown) is used to facilitate communication between the receiver (54) and the portion of the drive system (42), the processing unit (not shown) may be powered by a battery, such as a button cell battery, or any other suitable power source or device.
FIG. 6 depicts a schematic view of an alternate wirelessly controlled motorized vehicle system (310) that is similar to the system (10) depicted in FIG. 1. However, in this version, the system (310) comprises a motorized vehicle (320), a controller (330), a drive system (340), a wireless communications system (350) and an additional element, a manipulation device (370). Similar to the system (10) described above, a user can input a command (360) into the controller (330), and the command (360) is ultimately communicated to a portion of the drive system (342) via the wireless communications system (350), which comprises a transmitter (352) and a receiver (354). The portion of the drive system (342) may comprise one or more systems or components, including an engine, a transmission, a clutch assembly, a clutch plate, a throttle system, a throttle plate, an ignition system, a starter, or any other suitable system or component. It will be appreciated that the controller (330) and the wireless communications system (350) may be powered by a battery, such as a button cell battery, or any other suitable power source or device.
In the present example, the manipulation device (370) is in communication with the receiver (354) and the portion of the drive system (342). The manipulation device (370) may be configured to manipulate the portion of the drive system (342) in a manner corresponding to the command (360). For example, in one embodiment, the manipulation device (370) may be configured to open the throttle plate on the carburetor in response to a command to increase throttle. The manipulation device (370) may comprise a servo motor, a stepper motor, or any other suitable device. In particular, the manipulation device (370) may comprise a stepper motor configured to operate in temperatures up to about 150 degrees Fahrenheit or above. The manipulation device (370) may be connected to and derive power from a current generating portion of the drive system (340), such as the ignition coil (shown in FIG. 14 b) or any other suitable component of the motorized vehicle (320). In the present example, the system (310) comprises one manipulation device (370); however, it will be appreciated that any suitable number of manipulation devices may be used. For instance, a plurality of manipulation devices may be coupled with a plurality of portions of the drive system. In such an embodiment, each manipulation device would be coupled with a particular portion of the drive system.
As shown in FIG. 6, the manipulation device (370) is configured to receive the command (360) from the receiver (354) and manipulate the portion of the drive system (342) in a manner corresponding to the command (360). Similar to the system (10) described above, a processing unit (not shown), such as a microprocessor, a microcontroller, a parallax chip, or any other suitable device, may be used to facilitate communication between the receiver (354) and the manipulation device (370). In particular, the processing unit (not shown) may comprise an 8-bit PIC based microcontroller, but this is not required. The manipulation device (370) may be coupled with the portion of the drive system (342) via a linking member configured to translate the actuation of the manipulation device (370) into appropriate manipulation of the portion of the drive system (342). In one version (not shown), the manipulation device may be coupled with a throttle plate, such that when the manipulation device is actuated in response to a command to increase the throttle, the manipulation device positions the throttle plate toward an open or full-throttle position.
FIG. 7 depicts one embodiment of a linking member (380) adapted for use with the system of the present invention. As shown, the linking member (380) comprises a first attachment portion (382), a connecting member (384) and a second attachment portion (386). In this version, the first attachment portion (382) is configured to be attached to a manipulation device (not shown), and the second attachment portion (386) is configured to be attached to a portion of the drive system (not shown). The configuration of the linking member may vary depending on the particular portion of the drive system (not shown) that the linking member is attached to.
For example, FIG. 8 depicts a drive system (440) similar to the drive system (340) shown schematically in FIG. 6. As shown in FIG. 8, the drive system (440) comprises portion of a drive system (442), a manipulation device (470) and a linking member (480). In the present example, the portion of the drive system (442) comprises a clutch assembly comprising a clutch cover (444), also shown in FIG. 14 b, and a clutch plate (448). The clutch assembly may comprise a standard multi-disc clutch or any suitable clutch used in motorized vehicles, such as motorcycles. The remaining components of the clutch assembly are not shown. In this version, the clutch cover (444) comprises an inner surface (445).
In the present example the manipulation device (470) is mounted to the inner surface (445) and comprises an arm (472). The manipulation device (470) may be mounted to the inner surface (445) using bolts, screws, brackets, or any other suitable method or device, and the manipulation device (470) may comprise a servo motor, a stepper motor, or any other suitable device. In this version, the manipulation device (470) is configured to rotate the arm (472) in response to a command input by a user. As shown in FIG. 8, the manipulation device (470) is connected to a power source (not shown) via a first control wire (474), and the manipulation device (470) is configured to communicate with a receiver (not shown) via a second control wire (476). The power source (not shown) may comprise an ignition coil (shown in FIG. 14 b) or any other suitable component of the motorized vehicle. In addition, the receiver (not shown) in communication with the manipulation device (470) may be mounted in a compartment (shown in FIG. 14 b) mounted elsewhere on the motorized vehicle. It will be appreciated that mounting the manipulation device (470) to an easily removable component on the periphery of the motorized vehicle, such as the clutch cover (444) may enhance the ability of a user to replace the manipulation device (470) if necessary.
Returning to FIG. 8, the linking member (480) connects the arm (472) to the clutch plate (448). In this example, the linking member (480) comprises a first attachment portion (482) connected to a second attachment portion (484) via a connecting member (484). In the illustrated version, the first attachment portion (482) is connected to the arm (472), and the second attachment portion (484) is connected to the clutch plate (448). As shown, upon receiving a command to disengage the clutch, the arm (472) rotates, causing the clutch plate (448) to rotate and separate from the multi-disc clutch assembly (not shown) or standard clutch used in motorized vehicles, such as a motorcycle. When the command to disengage the clutch is no longer received, the arm (472) returns to its original position, thereby allowing the clutch plate (448) to engage the multi-disc clutch assembly (not shown) or standard clutch used in motorized vehicles, such as a motorcycle.
FIG. 9 depicts an alternate wirelessly controlled motorized vehicle system (510) that is similar to the system (10) depicted in FIG. 1. However, in this version, the system (510) comprises a motorized vehicle (520), controller (530), a drive system (540), a wireless communications system (550), and a central display unit (580). In the present example, the controller (530) functions similarly to the controller (30) described above, and the drive system (540) functions similarly to the drive system (40) described above. In addition, the drive system (540) comprises a portion of the drive system (542), similar to the drive system (40) and the portion of the drive system (42) described above.
As shown in FIG. 9, the wireless communications system (550) functions similarly to the wireless communications systems (50) described above. However, in this embodiment, the wireless communications system (550) is configured not only to allow wireless communication between the controller (530) and the portion of the drive system (542), as in the embodiments described above, but also to allow the central display unit (580) to wirelessly communicate with both the controller (530) and the portion of the drive system (542).

For example, in FIGS. 10-11, where the motorized vehicle (620) is a motorcycle comprising a gas tank (622), a battery (621), and a seat (623). In the illustrated version, the gas tank (622) comprises a cavity (624), a cover (626), and a channel (628). In this example, a central display device (680) is positioned within cavity (624). The cover (626) may be capable of being positioned directly above the cavity (624), thereby protecting the contents of the cavity (624), such as the central display device (680), from the elements, such as rain, snow, heat, and cold. Alternatively, as shown in FIGS. 10-11, the cover (624) may also be maneuvered to reveal the central display device (680), thereby enabling the user to view the information received and displayed by the central display device (680).
In addition, as shown in FIG. 11, the battery (621) may be mounted to the motorized vehicle (620) beneath the seat (623) (also shown in FIG. 14 a). The battery (621) may comprise a conventional 12-volt motorcycle battery. In the present example, the channel (628) provides a pathway for a power cord (682) to run from the cavity (624) to the battery (621).

It will be appreciated that the cavity (624) and the channel (680) may be formed within the gas tank using any suitable method.
Returning to FIG. 9, the central display unit (580) may be configured to receive a command from a user and communicate that command to the drive system (540) via the wireless communications system (550), similar to controller (30), however this is not required. The central display unit (580) may include a user interface, such as a touch screen or any other suitable device, to allow the user to input commands and/or navigate menus to view information received by the central display unit (580). As shown in FIG. 9, the system (510) comprises one central display unit (580); however, any suitable number of central display units (580) may be used.
It will be appreciated that the elimination of physical connections between the controls of a motorized device and the components of the motorized device may provide various benefits to the user. As mentioned above, the control cables connecting conventional controls to the associated mechanical components of the motorized vehicle are generally routed through the framework and other components of the motorized vehicle. It will be appreciated that it may be difficult to replace a damaged or broken control cable, because the user must not only remove the damaged or broken control cable, but he or she must also re-route the new control cable through the framework and other components of the motorized vehicle. In embodiments of the present invention, such as the handgrip assembly shown in FIGS. 3-5, instead of re-routing a new cable, the user may make repairs by removing a damaged computer chip containing the transmitter, receiver, or processing unit and inserting a replacement computer chip. It will be appreciated that a replacement protocol may be programmed into one of the components of the system, such as a central display unit or a processing unit within a controller, to facilitate the pairing and communication between the replacement computer chip and the existing components. Therefore, the cost and time required to re-route a new control cable may be eliminated by replacing the control cables with a wirelessly controlled motorized vehicle system, such as the embodiments shown in FIGS. 1-11 and described above.
In addition, as mentioned above, eliminating the control cables may allow for certain components of the motorized vehicle frame, such as the handlebars on a motorcycle, to be designed with enhanced ergonomic, aerodynamic and/or more aesthetically pleasing characteristics. Furthermore, the elimination of control cables and other physical connections may increase the customization available for motorized vehicles. Embodiments of the present invention may allow users to design unique components, rather than being required to select standard or stock components. Finally, it will be appreciated that embodiments of the present invention may facilitate maintenance and customization by providing an easily modifiable alternative to conventional control cables and other physical connections. For example, with a conventional motorcycle, when changing types of handlebars the user may be required to obtain and install a completely new control cable with a length customized to fit with the new handlebars. In various embodiments of the present invention, the user can simply remove the handgrip assembly and wireless communication components from the old handlebars and install those same components on the new handlebars, thereby reducing the cost and time associated with replacing the handlebars. These are just a few of the potential benefits of various embodiments of the present invention.
FIG. 12 depicts an alternate wirelessly controlled motorized vehicle system (710) comprising a motorized vehicle (720), a drive system (740), a gauge (790), a central display unit (780), and a wireless communications system (750). In this version, the drive system (740) comprises a portion of the drive system (742), similar to the drive system (40) and the portion of the drive system (42) described above. As shown, the wireless communications system (750) comprises a transmitter (752) and a receiver (754), which function similarly to the transmitter (52) and receiver (54) described above. It will be appreciated that the wireless communications system (750) may be powered by a battery or any other suitable power source or device.
In the present embodiment, the gauge (790) is configured to monitor the portion of the drive system (742) and collect information regarding the performance of the portion of the drive system (742). By way of example only, the gauge (790) may comprise an odometer configured to monitor the portion of the drive system (742) and collect information regarding the distance traveled by the motorized vehicle (720). In addition to an odometer, the gauge (790) may comprise a tachometer, a speedometer, or any other suitable device. It will be appreciated that, while the system (710) comprises one gauge (790) associated with one portion of the drive system (742), any suitable number of gauges and portions of the drive system may be used. The number of gauges may correspond to the number of portions of the drive system, but this is not required. In addition, the number of transmitters (752) and receivers (754) may correspond to the number of gauges (790), but this is not required.
In this version, as the gauge monitors the portion of the drive system (742) and collects information, the information is wirelessly communicated to the central display unit (780) via the wireless communications system (750). As shown, first, the information collected by the gauge is communicated to the transmitter (752) which is associated with the gauge (790). Next, the information is communicated wirelessly to the receiver (754) associated with the central display unit. Finally, in this version, the receiver (754) communicates the information to the central display unit (780), which is configured to display the information to a user.
Similar to the embodiments involving wireless communication between a controller and an associated mechanical component described above and shown in FIGS. 1-11, this embodiment involving wireless communication between a gauge and a display may provide several benefits to the user. For instance, as with conventional controls, conventional gauges are generally physically connected to the display, either by a control wire or some other physical connection. In many cases, the control wire or other physical connection must wind its way through the interior of the motor vehicle around and through the framework and other components, thereby making it difficult to replace. Replacing the physical connection with wireless communication may eliminate the time and cost required to replace such a physical connection. In addition, by eliminating the physical connections between conventional gauges and displays, it may be possible to include an increased number of gauges monitoring more portions of the motorized vehicle, including, perhaps, one or more portions of the motorized vehicle where it was previously impossible to place a gauge, thereby providing the user with more information regarding the performance of the motorized vehicle. Finally, as discussed above, embodiments of the present invention may allow fabricators to design more aesthetically appealing motorized vehicles, and increase the customization options available to users.
