FIG. 1 illustrates avehicle 10 and atrailer 11. Thetrailer 11 is controllably secured to thevehicle 10 to form a vehicle andtrailer assembly 12. The vehicle andtrailer assembly 12 utilizes atrailer backing program 14 of the present invention. Throughout the application the relative directions of forward and rear are in reference to the direction which an operator for thevehicle 10 would be facing when operating thevehicle 10 in a drive gear. Therefore, in operation of thetrailer backing program 14 thevehicle 10 would be in a reverse gear and the operator may be facing backward. Thetrailer backing program 14 provides the vehicle operator with a method of electronically defining an intendedbacking path 18 of the vehicle andtrailer assembly 12. Thetrailer backing program 14 utilizes the intendedbacking path 18 to control movement of vehicle andtrailer assembly 12. - Referring to
FIG. 1 , a first embodiment for utilizing thetrailer backing program 14 is described. Anelectronic input device 16 is electronically connected to thevehicle 10 and thetrailer backing program 14. Thetrailing backing program 14 includes acontrol unit 22 within thevehicle 10. Thecontrol unit 22 may be connected to at least onevehicle system 24 such as a powertrain system, a steering system and/or a brake system to control and direct movement of the vehicle andtrailer assembly 12. Thecontrol unit 22 sends instructions to thevehicle systems 24 to move the vehicle andtrailer assembly 12 along the intendedbacking path 18 to afinal location 20. The steering, braking, and other controls are calculated by thecontrol unit 22 based upon the intendedbacking path 18 input by the vehicle operator. - The
electronic input device 16 includes aninput control mechanism 26 and adisplay screen 28. Theelectronic input device 16 may be incorporated into thevehicle 10. For example, theelectronic input device 16 may include a control panel anddisplay screen 28 already within thevehicle 10, e.g. part of a navigation system or entertainment unit, or may be a separate device, such as a hand-held navigation system, that is electrically connected to thevehicle 10. Theelectronic input device 16 may also be partially incorporated into thevehicle 10 such as thedisplay screen 28, but have a separateinput control mechanism 26. Theinput control mechanism 26 may be a joystick, knob, slider device, physical buttons, virtual “touch screen” buttons, handheld electronic device such as a “smart phone” or voice control inputs. Theelectronic input device 16 may be connected through a wired connection, such as a USB connector, or may be wirelessly linked with thevehicle 10. Theinput control mechanism 26 may control an on-screen locator 40 on thedisplay screen 28. - The
display screen 28 may illustrate a schematic or image of an area located behind the vehicle andtrailer assembly 12. The on-screen locator 40 may be initially positioned at an initial location, e.g. at a rear position of the vehicle andtrailer assembly 12. Theinput control mechanism 26 can be used to define and/or control the vehicle and trailer assembly's intendedbacking path 18 by pressing physical buttons, “touch screen” buttons, or by detecting movement of theinput control mechanism 26 and measurement of internal accelerometers and/or gyroscope. This could also be completed by using voice controls or a joystick type device to move the on-screen locator 40 on thedisplay screen 28 to outline the intendedbacking path 18. Therefore, theinput control mechanism 26 can be manipulated to move the on-screen locator 40 on thedisplay screen 28 to outline the intendedbacking path 18. Thetrailer backing system 14 would determine from the input the actual distances and movements required to direct the vehicle andtrailer assembly 12 to follow the intendedbacking path 18. -
FIG. 2 illustrates a first embodiment of a method of using thetrailer backing system 14, shown at 29. The path input mode for thetrailer backing system 14 is initiated,step 30. A vehicle operator would use theinput control mechanism 26 to input an intendedbacking path 18 for the vehicle andtrailer assembly 12 into theelectronic input device 16,step 32. The intendedbacking path 18 would include the suggested backing route and afinal parking position 20. Theinput control mechanism 26 may be utilized to input the intendedbacking path 18 by successively inputting each leg of a suggested route. For example, theinput control mechanism 26 may be a joystick or knob that is part of the vehicle navigation and entertainment unit. Theinput control mechanism 26, e.g. joystick, knob, etc, can be manipulated to move the on-screen locator 40 over each successive leg of the intendedbacking path 18. The intendedbacking path 18 would include the suggested backing route and afinal parking position 20. The vehicle operator would indicate once the complete backing path is entered by ending the path input mode,step 34. Once the intendedbacking path 18 is entered into thetrailer backing program 14 the vehicle operator would instruct thetrailer backing system 14 to follow the intendedbacking path 18,step 36. Thetrailer backing system 14 would send instructions to thevehicle systems 24 to direct the vehicle andtrailer assembly 12 along the intendedbacking path 18 to thefinal position 20,step 38. - Alternately, each leg of the intended
backing path 18 may be entered and thetrailer backing system 14 may move the vehicle andtrailer assembly 12 to that location prior to entering the next leg of the intendedbacking path 18. This may be accomplished by repeating steps 30-38 for each leg of thebacking path 18. -
FIGS. 3-5 illustrate a second embodiment of atrailer backing system 114 for avehicle 110 andtrailer 111 which are connected together to form a vehicle andtrailer assembly 112. Thetrailer backing program 114 provides the vehicle operator a method of defining the intendedbacking path 118 of the vehicle andtrailer assembly 112.

The trailingbacking program 114 includes acontrol unit 122 within thevehicle 110 connected to at least onevehicle system 124 such as a powertrain system, a steering system and/or a braking system to control and direct movement of the vehicle andtrailer assembly 112. - The
electronic input device 116 includes aninput control mechanism 126 and may include adisplay screen 128. Theelectronic input device 116 may be incorporated into thevehicle 110. For example, theelectronic input device 116 may include a control panel anddisplay screen 128 already within thevehicle 110, e.g. part of a navigation system or entertainment unit, or may be a separate device. Theelectronic input device 116 may also be partially incorporated into thevehicle 110 such as thedisplay screen 128, but have a separateinput control mechanism 126. Theinput control mechanism 126 is preferably a voice control system, shown inFIG. 4 . Theinput control mechanism 126 may control an on-screen locator 140 on thedisplay screen 128. -
FIG. 4 illustrates an embodiment of aninput control mechanism 126 that is a voice control system. Thevoice control system 126 may be connected to or partially incorporated withother vehicle 110 devices for performingvarious vehicle 110 functions. The other devices 142 a-e that may be electronically connected include, for example, atelephone 142 a, anavigation system 142 b, anaudio system 142 c, a CD changer, 144 d, or an HVAC system 144 e. Thevoice control system 126 includes aninterface 141, the audio input 146 and anaudio output 144 for thevehicle 110. Theinterface 141 converts the audio input 146 from the vehicle operator into an electrical signal that can be used by thetrailer backing system 114 and/or other devices 142 a-e. Additionally, theinterface 141 converts the electrical signals from thetrailer backing system 114 and other devices 142 a-e to anaudio output 144 for the vehicle operator. - Referring to
FIGS. 3-5 , a second embodiment of a method of using thetrailer backing system 114 is shown at 129. A vehicle operator would use the voice controlledinput control mechanism 126 to input an intendedbacking path 118 for the vehicle andtrailer assembly 112. The path input mode for thetrailer backing system 114 is initiated,step 130. From within the passenger compartment a vehicle operator would use the voice controlledinput control mechanism 126 to input an intendedbacking bath 118 for the vehicle andtrailer assembly 112,step 132. Simple directions and distances may be used for voice input of the intendedpath 118, e.g. “back 10 feet”, “stop”, “turn right 90 degrees”, “final position”. The “on-screen”locator 140 may move to illustrate the position of the vehicle andtrailer assembly 112 while also following the voice instruction from the vehicle operator. - The vehicle and
trailer assembly 112 would follow each instruction as spoken and recorded by the input device 142. After the instruction from the vehicle operator is complete the path input mode is ended,step 134. After each step is entered into thetrailer backing program 114 thetrailer backing system 114 follows the instructions along the intendedbacking path 118,step 136. Thetrailer backing system 114 would send instructions to thevehicle system 124 to direct the vehicle andtrailer assembly 112 along the intendedbacking path 118,step 138. By repeating the steps 130-138 the vehicle andtrailer assembly 112 may be moved to a desiredfinal parking position 120. -

The trailingbacking program 214 includes acontrol unit 222 within thevehicle 210 connected to at least onevehicle system 224 such as a powertrain system, a steering system and/or a braking system to control and direct movement of the vehicle andtrailer assembly 212. - The
electronic input device 216 includes aninput control mechanism 226 and adisplay screen 228. Theelectronic input device 216 may be incorporated into thevehicle 210. Theelectronic input device 216 may be partially incorporated into thevehicle 210 such as thedisplay screen 228, but has a separateinput control mechanism 226. For example, theelectronic input device 216 may include a control panel anddisplay screen 228 already within thevehicle 210, e.g. part of a navigation system or entertainment unit. Theinput control mechanism 226 is a handheld electronic device and may alternatively include thedisplay screen 228. The handheldelectronic device 226 may be a smart phone, a PDA, a handheld GPS, a key-fob, etc. - The handheld
electronic device 226 may control an on-screen locator 240 on thedisplay screen 228. The handheldelectronic device 226 may be connected through a wired connection, such as a USB connector, or may be wirelessly linked with theelectronic input device 216. - A
control unit 222 within thevehicle 210 may be connected to at least onevehicle system 224 such as a powertrain system, a steering system and/or a braking system to control and direct movement of the vehicle andtrailer assembly 212. Thetrailer backing system 214 could be designed to work real-time in which the vehicle andtrailer assembly 212 follows the handheldelectronic device 226 while the operator is walking thepath 218. Alternatively, thetrailer backing system 214 could be designed to work only after thepath 218 has been mapped completely; allowing the person to first return to thevehicle 210. -
FIG. 7 illustrates a third embodiment of a method of utilizing thetrailer backing system 214 ofFIG. 6 . A vehicle operator or passenger exits thevehicle 210 with the handheldelectronic device 226 in hand. When arriving at the back of thetrailer 212, the operator initiates the path input mode on the handheldelectronic device 226,step 230 and proceeds to walk the intendedbacking path 218,step 232. When the operator arrives at the desiredfinal parking position 220 for the back of the trailer, the path input mode is ended,step 234. - Once the intended
backing path 218 is entered into thetrailer backing program 214 the vehicle operator would instruct thetrailer backing system 214 to follow the intendedbacking path 218,step 236. Thetrailer backing system 214 sends instructions to thevehicle system 224 to direct the vehicle andtrailer assembly 212 along the intendedbacking path 218 to thefinal parking position 220,step 238. Thetrailer backing system 214 autonomously (driver not behind the wheel) or semi-autonomously (driver behind the wheel) controls the lateral and longitudinal motion of the vehicle andtrailer assembly 212 to follow thepath 218 which was mapped out by the handheldelectronic device 226. - While the best modes for carrying out the invention have been described in detail the true scope of the disclosure should not be so limited, since those familiar with the art to which this invention relates will recognize various alternative designs and embodiments for practicing the invention within the scope of the appended claims.
