Title: Vehicle control system with selectable vehicle style image and associated methods

Description:
FIELD OF THE INVENTION  
       [0001] The present invention relates to the field of vehicle remote control systems, and, more particularly, to a vehicle remote control system including a display for displaying vehicle images.  
       BACKGROUND OF THE INVENTION  
       [0002] Vehicle security systems are widely used to deter vehicle theft and perform various security-related vehicle functions. A typical vehicle security system includes a controller having a receiver connected thereto. The controller may perform security-related functions, such as locking/unlocking doors, operating windows, and/or switching between armed and disarmed modes responsive to signals received from one or more remote transmitters. When in the armed mode, the controller may generate an alarm indication at the vehicle responsive to a vehicle security sensor indicating a vehicle security breach. A remote transmitter is typically carried by the owner or user of the vehicle when away from the vehicle.  
       [0003] A vehicle remote control system may also be used for remote starting of the vehicle engine. This remote starting may be in addition to security related functions, or in lieu thereof.  
       [0004] Newer vehicle control systems are being developed and sold with two-way communications capability between the vehicle controller and the handheld remote device. For example, Crimestopper of Simi Valley, Calif. offers a model under the designation CS-2006FM that includes two-way communication. The remote device includes a liquid crystal display (LCD) that displays a vehicle image.  
       [0005] Along these lines, U.S. Pat. No. 5,940,007 to Brinkmeyer et al. discloses a remote device that displays an image of a vehicle. The remote device receives signals transmitted from the vehicle controller and indicates a vehicle security condition on the displayed vehicle image. For example, the transmitter may display a blacked-out portion of the vehicle image to indicate a break in.  
       [0006] Some vehicle security systems are adapted for multi-vehicle operation. More particularly, multiple vehicles may be operated using one remote transmitter or remote device. Controllers in each vehicle are responsive to only one signal bank from among different signal banks for different vehicles. An example, of such a high-quality, multi-vehicle security system is the Excalibur® 1800ATV offered by Omega Research and Development of Douglasville, Ga. The remote devices may be switched between signal banks to operate a desired vehicle. One shortcoming with these systems, however, is that it may be difficult for the user to determine which vehicle will be operated based upon the selected signal bank.  
       SUMMARY OF THE INVENTION  
       [0007] In view of the foregoing background, it is therefore an object of the present invention to provide a remote control system for a vehicle that reduces the possibility of confusion for the vehicle to be controlled by the remote device.  
       [0008] This and other objects, features, and advantages of the present invention are provided by a vehicle remote control system including a controller at the vehicle, and at least one remote device for wireless communication with the controller. More particularly, the remote device may include a portable handheld housing, and a display, such as an LCD, for displaying a selected vehicle style image from among a plurality of different vehicle style images. The different vehicle style images may include a sedan style image, a pickup truck style image, and/or a van style image, for example. The LCD may comprise a common image portion for all of the different selectable vehicle style images, and at least one other defining image portion selectively operated together with the common image portion to display the selected vehicle style image. Accordingly, the user may personalize his remote device, the user&#39;s convenience is enhanced for multiple vehicle operation, and a relatively low cost LCD may be used.  
       [0009] The controller may perform at least one vehicle security function, and wherein the LCD may also display at least one vehicle security function image based upon the controller. In addition, the controller may perform at least one vehicle starting function, and the LCD may also display at least one vehicle starting function image based upon the controller.  
       [0010] The remote device may further comprise a processor for driving the LCD. The processor may be switchable to a selection mode for permitting user selection of the selected vehicle style image. In some embodiments, the processor may operate using a selected signal bank from among a plurality of signal banks for respective different vehicles. In these embodiments, the selected vehicle style image may be selected based upon the selected signal bank. In other words, if the user selects a different signal bank, the displayed vehicle style image also changes to the corresponding vehicle style image.  
       [0011] The LCD may further display alphanumeric indicia associated with the selected signal bank. More particularly, the LCD may display a license plate outline on the vehicle image surrounding the alphanumeric indicia. This additional display may be helpful to the user when at least some of the different vehicles to be controlled have the same vehicle style.  
       [0012] The controller may also transmit at least one signal to the remote device, and, this signal may be used to select the selected vehicle style image to correspond to a vehicle in which the controller is positioned. In other words, the selected vehicle style image may be changed from its current image to correspond with the vehicle style image of the vehicle from which an alarm indication is received.  
       [0013] The controller may comprise a first wireless transceiver, and the at least one remote device may comprise a second wireless transceiver for two-way communication with the first wireless transceiver. For example, frequency modulation (FM) is typically used for the two-way wireless transceivers. The at least one remote device may further include at least one of a tactile indicator, and an audible indicator carried by the portable housing. The remote device may also include a battery carried by the housing. In some embodiments, a display other than an LCD may be used, such as, for example, a plasma gas display.  
       [0014] A method aspect of the invention is for using a remote device for communicating with a controller at a vehicle as part of a remote control system for the vehicle. The remote device may comprise a portable handheld housing to be carried by a user when away from the vehicle, and a display mounted on the portable housing. The method may include selecting a selected vehicle style image from among a plurality of different selectable vehicle style images, and displaying the selected vehicle style image on the display.

     [0030] In one class of embodiments, the processor  34  of the remote device  30  is switchable to a selecting mode for permitting user selection of the selected vehicle image  40 , such as by predetermined operation of one or more of the switches  33   a,    33   b,    33   c,    33   d.  Accordingly, a user may customize his remote device for his particular style of vehicle. This may be especially beneficial where the household includes several vehicles of different styles, and multiple such remote devices are used by different household members.  
     [0031] The remote transmitter  30  may also be selectively operable using a selected signal bank  27  from among a plurality of signal banks for different vehicles. In these embodiments, the processor  34  selects the selected vehicle type image based upon the selected signal bank. Of course, vehicle style images can be selected or programmed for each different signal bank as will be appreciated by those skilled in the art. Accordingly, the remote device  30  displays on its LCD  36  a corresponding vehicle image  40  for the selected signal bank  27 .  
     [0032] The LCD  36  may further display alphanumeric indicia  48  associated with the selected signal bank. More particularly, the LCD  36  may display a license plate outline  47  on the vehicle image surrounding the alphanumeric indicia  48 . This additional display may be helpful to the user when at least some of the different vehicles to be controlled have the same vehicle style.  
     [0033] The controller  20  may also transmit at least one signal to the remote device  30 , and, this signal may be used to select the selected vehicle style image  40  to correspond to a vehicle in which the controller is positioned. In other words, the selected vehicle style image  40  may be changed from its current image to correspond with the vehicle style image of the vehicle from which an alarm indication is received for the user&#39;s convenience.  
     [0034] Turning now additionally to FIGS.  3 - 6 , exemplary vehicle style images  40  as may be used by the LCD  36  are now further described.

For example, the common image portion  40   a  can be a single pattern in the LCD  36  as designed and manufactured, as will be appreciated by those skilled in the art. The other vehicle style images  40   b - 40   d  include respective defining image portions selectively operated together with the common image portion  40   a  to display the selected vehicle style image. For example, the sedan style image  40   b  includes the rear window, rear roof, and trunk defining image portions within the dashed box  49  (FIG. 4). Likewise, in FIG. 5, the defining image portions  49   c  form the back window and truck bed enclosed within the dashed box  49   c.  In FIG. 6 the image defining portions form the rear cargo or passenger area within box  49   d.  Of course, the van style image  40   d  is also similar to an SUV style image and can also be used for an SUV.  
     [0036] As also shown in FIG. 3 the common image portion  40   a  may also include a license plate outline  47   a  so that each vehicle style image  40   b - 40   d  may further include an alphanumeric indicia  48   b - 48   d,  such as the illustrated numbers  1  through  3 , surrounded by the license plate outline  47   b - 47   d.  This additional display may be especially helpful to the user when at least some of the different vehicles to be controlled have the same vehicle style. As noted above, the controller  20  may also transmit at least one signal to the remote device  30 , and, this signal may be used to select the selected vehicle style image as well as the corresponding alphanumeric indicia to correspond to a vehicle in which the controller is positioned.  
     [0037] Referring now additionally to FIG. 7, additional aspects of the remote device  30  and its LCD display  36  are now described. In particular, the LCD  36  may display information relating to security and/or remote starting of the vehicle. For example, indications illustratively include a low battery indication  51 , a mute indication for indicating whether the vibration alert or chirp alert is selected, phrases “DIS”  53  and “ARM”  54  for indicating armed or disarmed status, a door lock and unlock image  55 , a hood/trunk zone violated image  56 , a door zone violated image  57 , a shock sensor image  60 , a hammer image indicating the violated zone  61 , a valet image  62  for the valet mode being selected, a channel two  63  and a channel three  64  image, an exhaust image  65  indicating the vehicle has started, and a four digit image  66 .  
     [0038] A pager feature may also be provided wherein a switch in the vehicle and connected to the controller  20  is used to cause the remote device  30  to issue a tactile (vibration) or audible paging alert as will be appreciated by those skilled in the art. Many other convenience and/or security type features are also contemplated by the present invention as will be appreciated by those skilled in the art.  
     [0039] The four digit image  66  may be used to display the time, for example. Also the four digit image  66  can display the number of remote devices learned into the controller for additional security. This remote transmitter verification feature is further described, for example, in U.S. Pat. Nos. 5,654,688 and 6,140,938, the entire disclosures of which are incorporated herein by reference.
