FIG. 7 is another top view of the example hand control device. - Referring to
FIG. 1 , anexample vehicle 15 is schematically shown and includes amotor 14,transmission 16,brake system 55 andcontrol system 10. Thecontrol system 10 includes ahand control device 12 mounted where a standard steering wheel is typically mounted on asteering column 22 of thevehicle 15. The examplehand control device 12 provides a means to control all vehicle functions by an operator with limited dexterity and mobility. It should be appreciated that the examplehand control device 12 may be utilized to operate any type of vehicle, and/or driving simulator or game where control over common driving functions is required. - Accordingly, the
example control device 12 provides throttle control, brake control as well as clutch actuation and gear shifting capability tailored operation by a differently abled vehicle operator. In this example, thehand control device 12 is part of asystem 10 integrated into a vehicle to enable control of all vehicle functions with only limited movement of an operators hands and arms. - Referring to
FIG. 2 with continued reference toFIG. 1 , the examplehand control device 12 includes features that communicate with acontroller 18 to control operation of themotor 14 andtransmission 16. Theexample controller 18 could be a separate dedicated controller for thehand control device 12, or could be implanted as a software program in an existing vehicle Electronic Control Unit (ECU). Moreover, thehand control unit 12 could include specific connections to enable use with an existing vehicle ECU. Thehand control device 12 further includes features that communicate with apedal box 20 utilized to control operation ofconventional vehicle pedals 28A-C. Theexample pedal box 20 includesactuators 60A-C that are actuated by thecontroller 18 responsive tocommand signals 56 generated by thehand control device 12. Theactuators 60A-C could operate hydraulically, electrically, pneumatically or by way of any other operating means responsive to signals generated by thehand control device 12. As appreciated, the control functions of the throttle, brake and clutch could be operated entirely by signals generated through control movements of thehand control device 12 and therefore not require thepedal box 20. - Referring to
FIG. 3 , one disclosed example embodiment includes controls implemented by manual operation of thehand control device 12. One illustrated example is mechanical control ofvehicle braking system 54 through a mechanical linkage between a portion of thevehicle control 12 and an existing brake pedal 28 in the vehicle. In this example, afirst link 24 is attached to asecond link 26. Thesecond link 26 is movable along thesteering column 22 to enable rotation of thehand control 12 while also allowing movement axially along thesteering column 22. Thesecond link 26 is in turn attached either directly or through another link to the brake pedal to control braking in response to actuation of thehand control 12. In this manner, thehand control 12 can be utilized and adapted for use in vehicles that include conventional controls. - Referring to
FIGS. 4, 5, 6 and 7 with continued reference toFIG. 2 , the disclosedhand control 12 includes afirst arm 36 and asecond arm 38 that are each pivotally mounted to abase portion 46. Thefirst arm 36 includes an upper portion and lower portion that extend from thebase portion 46 and pivot together about Axis A1. Thesecond arm 38 includes an upper portion and a lower portion that pivot together about an Axis A2. Thebase portion 46 is mountable to thesteering column 22 of the vehicle. In one example embodiment, thebase portion 46 is mounted to thesteering column 22 such that the steering column rotates responsive to rotation of thehand control 12. In another disclosed embodiment, thebase portion 46 rotates to drive a steering sensor 58 (schematically shown inFIG. 5 ) that generates a signal that is processed by thecontroller 18 to provide a signal to anactuator 50 of thesteering system 48 that commands a proportional turn of the wheels. Thesteering sensor 58 may be any sensor capable of generating signals indicative of a rotation of thehand control 12. - The upper and lower portions of the first arm spaced apart to support a
first spool 32 therebetween. Thesecond arm 38 supports asecond spool 30 between the upper and lower arms. Thefirst spool 32 is rotatable about an axis B1 on thearm 36 and is utilized to control throttle functions of thevehicle 15. Thesecond spool 30 is rotatable about an axis B2. The first andsecond spools hand control 12. - Each of the
first spool 32 and thesecond spool 32 include anupper flange 64A-B and alower flange 66A-B attached to agripping member 68A-B. The grippingmember 68A-B is disposed along corresponding axes B1 and B2. Akeeper bar 34A-B is attached at an outer periphery of the upper andlower flanges 64A-B, 66A-B for eachspool spools keeper bar 34A-B can be modified to accommodate the abilities of the operator to enable continuous engagement of thehand control 12 during operation. - Both the
first arm 36 and thesecond arm 38 are movable relative to thebase 46. In this example, thefirst arm 36 is movable about the axis A1 forward and back to shift gears of thetransmission 16. In this example, thearm 36 is incremented forward to downshift and pulled back to upshift thetransmission 16. In this example embodiment, thetransmission 16 is a sequential transmission and therefore thefirst arm 36 is moved pulled back to upshift and pushed forward to downshift and returns to a beginning position after each shift. Subsequent movement forward or backward of thefirst arm 36 provides a corresponding upshift or downshift from the current gear. - Forward and backward movement of the
first arm 36 is sensed byshift sensor assembly 40. Theshift sensor 40 generates a signal that thecontroller 18 translates into a command to thetransmission actuator 52 to shift thetransmission 16. In the disclosed example theshift sensor assembly 40 is a micro-switch; however any sensor or switch that generates a signal responsive to movement of thefirst arm 36 could also be utilized and is within the contemplation of this disclosure. Thefirst arm 36 is held in place by aball spring detent 72 to prevent accidental shifts. - In this example, the
first spool 32 supported on thefirst arm 36 provides the throttle function. Thespool 32 twists relative to thearm 36 and operates as an accelerator similar to those utilized in motorcycles. Thespool 32 includes aspring 76A (schematically shown inFIG. 6 ) that returns the spool to a neutral position. Athrottle sensor 74A is provided that generates a signal sent to thecontroller 18 indicative of rotation to actuate the throttle and increase engine speed. - The
second arm 38 provides a braking function. Pushing forward on thesecond arm 38 initiates actuation of thebrake system 55 of the vehicle (Shown schematically inFIGS. 1 and 2 ). Abrake sensor 42 senses movement of thesecond arm 38 and generates a signal indicative of that movement. Abrake controller 54 then generates a signal corresponding movement of thesecond arm 38 to actuate individual brakes at each wheel. This movement is then relayed to thecontroller 18 and utilized either to directly control vehicle brakes through an electrically operated braking system or alternatively for communicating with apedal box 20 that is mounted in the vehicle and operates the conventionally configured vehicle pedals, schematically indicated at 28 inFIG. 2 . - The
second spool 30 is rotatable to engage or disengage a vehicle clutch 25 (schematically shown inFIG. 1 ). Thesecond spool 30 is configured like the first spool and includes a rotation sensor 74B and return spring 76B. In this example, the rotation sensor 74B generates a signal used to control thevehicle clutch 25. - A
clutch lock 44 is disposed on thesecond arm 38. Thespool 30 is rotatable to operate the vehicle clutch at lower speeds and theclutch lock 44 is configured to engage at a set vehicle speed. In the disclosed example once the vehicle accelerates past 3-5 miles per hour, theclutch lock 44 will lock thesecond spool 30 in place and prevent further actuation of the clutch 25. Theexample transmission 16 is a sequential transmission and therefore shifting occurs sequentially through upshifts and downshifts. Other types of transmission such as for example, an automatically shifted transmission or any other transmission configuration utilized with a motor vehicle are within the contemplation and are compatible with the disclosedhand control device 12. - Referring to
FIG. 2 with continued reference toFIGS. 4, 5, 6 and 7 , theexample hand control 12 communicates electronically through thecontroller 18 with thepedal box 20. Thepedal box 20 includesactuators 60A-C controlled by thecontroller 18 responsive to movements and signals 56 generated by the sensors provided in thehand control 12. Thepedal box 20 may be retrofitted to control conventional pedals as is schematically illustrated. Thepedal box 20 is mountable to a vehicle floor proximate to the pedals and interfaces with the current vehicle pedals 28 such that they are depressed or released depending on movement and signals generated by thehand control 12. Accordingly, in this way thehand control 12 can be adapted for implementation in any vehicle without significant modification to existing vehicle controls. - Accordingly, the example steering and vehicle control system provides control over complex vehicle functions including transmission shifting and control to enable limited mobility drivers with the opportunity to operate a motor vehicle.
- Moreover, the
example control device 12 may be utilized independent of a motor vehicle such as within a driving simulation device and/or gaming system. Thecontrol device 12 could be utilized to provide control functions for operation of a simulated driving experience for recreation and/or to provide an environment in which an operator could practice operation of thehand control device 12 independent of a motor vehicle. In such a system thecontrol device 12 would be configured to provide inputs to the system generating a graphical representation of a vehicle. The inputs would be in the form of signals corresponding to operation of the graphical representation of the vehicle. Accordingly, for use with a driving simulation device, the example hand control device would be configured to provide inputs to the driving simulator for generating corresponding vehicle operation within a graphical representation generated by the driving simulator - The terms forward and back are used in this disclosure are used to provide context for relative movement of features of the
control device 12. In this disclosure the term forward is intended to mean vehicle forward and the term rearward is meant to mean vehicle rearward. Moreover, any additional directional terms relate to a position of a vehicle operator seated within a vehicle with a driver's position being on a left side of the vehicle. These directional descriptions are to clarify the features in this disclosure and not intended to be limited. Additionally, the term motor vehicle is utilized in this application to include vehicles such as go-carts, trucks, vans and automobiles including internal combustion engines, electric motors or any other known energy conversion device. One skilled in the art with the benefit of this disclosure will understand that different reference orientations are within the contemplation of this disclosure. Additionally, any term set out in this disclosure is provided as an example and could be structured differently to include making features integral or separating structures in to multiple components and still fall within the contemplation of this disclosure. - Although a preferred embodiment of this invention has been disclosed, a worker of ordinary skill in this art would recognize that certain modifications would come within the scope of this invention. For that reason, the following claims should be studied to determine the true scope and content of this invention.
