The present specification generally relates to an apparatus and method for a system for suggesting a lane of travel and, more specifically, an apparatus and method for suggesting a specific lane of travel to a user in a vehicle to provide a preferred lane of travel based on preselected criteria.
Navigational routing systems using GPS are known. While these systems may provide certain lane guidance relating to suggesting a lane because of an upcoming turn or exit, present systems do not provide for lane suggestion using information from sensors within the vehicle or from external third party or vehicle-to-vehicle data. Accordingly, there exists a need for alternative lane suggestion systems for providing a preferred lane of travel to a user in a vehicle.
In one embodiment, a lane suggestion system for a vehicle is provided including a GPS unit and a processor in communication with the GPS unit, the processor configured to determine a first optimal lane of travel based on information received from the GPS unit, the processor configured to continuously monitor changes to vehicle data and external data. If a change in either the vehicle data or the external data is detected by the processor, then the processor calculates a second optimal lane based on the change in the vehicle data or the external data. If the second optimal lane is most efficient, faster and/or safer as compared to the first optimal lane, then the second optimal lane is communicated to a user of the vehicle. If the first optimal lane of travel is the most efficient, faster and/or safer as compared to the second optimal lane, then the first optimal lane of travel is continuously communicated to the user of the vehicle.
In another embodiment, a lane suggestion system for a vehicle is provided having a GPS unit and a processor in communication with the GPS unit, the processor configured to determine a first optimal lane of travel based on information received from the GPS unit, the processor configured to continuously monitor changes to vehicle data and external data. If a change in either the vehicle data or the external data is detected by the processor, then the processor calculates if the change in the vehicle data or the external data alters the first optimal lane of travel. If the processor determines that the first optimal lane is altered, then a second optimal lane of travel is communicated to the user of the vehicle.
In yet another embodiment, a method of providing a lane suggestion to a user is provided including the steps of receiving input regarding a desired end location into a GPS unit, processing by a processor the input from the GPS unit to determine an first optimal lane of travel based on input from the GPS unit where the processor continuously monitors changes to both vehicle data and external data, the processor determining a second optimal lane of travel based on a change to the vehicle data and the external data and comparing by the processor of the first optimal lane of travel and the second optimal lane of travel, if the processor determines the second optimal lane of travel to be more efficient, faster and/or safer in comparison to the first optimal lane of travel, the processor then communicates the second optimal lane of travel to the user.
These and additional features provided by the embodiments described herein will be more fully understood in view of the following detailed description, in conjunction with the drawings.
The embodiments set forth in the drawings are illustrative and exemplary in nature and not intended to limit the subject matter defined by the claims. The following detailed description of the illustrative embodiments can be understood when read in conjunction with the following drawings, where like structure is indicated with like reference numerals and in which:
A lane suggesting system 100 for a vehicle 102 is provided having a GPS unit 104, a processor 106, and a communication system 108. The GPS unit 104 is mounted within the vehicle and configured to determine location and to determine a route of travel based on input from a user. The GPS unit 104 is in direct communication with the processor 106. The processor 106 receives both vehicle data 110 and external data 112. The processor 106 uses the vehicle data 110 and the external data 112 to determine a preferred lane of travel based on preselected criteria(e.g., the fastest, safest, and/or most efficient lane of travel (or route)). The preselected criteria can be related to vehicle volume, distances, weather conditions, construction, road conditions, etc.
The vehicle data 110 may include information received from external vehicle sensors 114. The external vehicle sensors 114 may be sensors mounted to exterior body panels of a vehicle to collect information such as the proximity of other vehicles (e.g., to identify vehicles traveling too close to the user vehicle). The vehicle data 110 may include GPS stored data 116. The GPS stored data 116 may include learned information by the GPS unit 104 and the processor 106 relating to lane travel on a particular route.
The external data 112 may be data relating to vehicle-to-vehicle (V2V) 118, information from the Department of Transportation (DOT) 120, information relating to weather conditions 122, and/or information from crowdsourcing 124.
Vehicle-to-vehicle information 118 from the external data 112 may include information transferred from other surrounding vehicles relating to emergency vehicles 130, student drivers 132, and/or learned information 134. Vehicle-to-vehicle systems, such as those used to collect vehicle-to-vehicle information 118 such as in the present specification, are an automotive technology designed to allow automobiles to “talk” to each other. Vehicle-to-vehicle systems frequently use a region of the 5.9 gHz band. Alternatively, vehicles using vehicle-to-vehicle technology may communicate via Bluetooth or other known sources.
In some embodiments, such as illustrated in
Cameras or sensors 140 operated by the Department of Transportation 120 may include cameras or sensors mounted to roadways to monitor flow of traffic and/or accidents on a particular road or in a particular lane. The Department of Transportation 120 may also monitor plowing/salting 142 on specific lanes of travel. If a particular lane has been plowed and salted, that information may be communicated to the processor 106. Furthermore, high occupancy vehicle (HOV) lanes 144 in certain areas may be communicated from the Department of Transportation 120 to the processor 106 for purposes of determining a preferred lane of travel.
Weather conditions 122 may be communicated via a cloud or other cellular network to the processor 106. Weather conditions 122 may include information relating to an incoming storm, ice over the road, snow on the road, hail, or other similar road conditions which may pose non-optimal driving and/or lane conditions.
Crowdsourcing 124 may also be used to determine an optimal lane of travel. Crowdsourcing 124 may be communicated to the processor 106 by means of the cloud over a cellular or Wi-Fi network. Crowdsourcing information may include high traffic areas 146, road hazards 148, weather conditions 150, and/or construction 152. Crowdsourced information may be acquired from various users of crowdsourcing 124 whereby the users input information relating to high traffic areas 146, road hazards 148, weather conditions 150, and/or construction 152 into the crowdsourcing 124 program. Information relating to crowdsourcing 124 may then be communicated to the processor 106 through a Wi-Fi or cellular connection.

In this embodiment, if the processor 106 determines that the data 110, 112 has changed, the processor 106 then determines a second preferred lane of travel based on the data 110, 112. At step 217, the processor 106 compares the first preferred lane to the second preferred lane. Step 219 requires communication of the preferred lane (e.g., most efficient, safest, and/or fastest lane) to the user based on the processor 106 determination. If the processor determines that the second preferred lane best meets the preselected criteria, (e.g., is more efficient, safer, and/or faster), then the second preferred lane is displayed or otherwise communicated to the user. If the processor 106 determines that the first preferred lane still best meets the preselected criteria (e.g., is still the most efficient, fastest, and/or safest), then no change is communicated to the user and the user is instructed to continue on the lane they are currently in. The system continuously monitors 218 changes to vehicle data 110 and external data 112.

The user vehicle 310 includes the lane suggestion system in accordance with one or more embodiments shown and described in the present specification. In the lane condition 300, a tailgater 312 is provided within the first lane 302, a moving vehicle 314 is provided in the second lane 304 directly adjacent to the user vehicle 310. The third lane 306 includes a stopped vehicle 316. In the lane condition 300, the user of the user vehicle 310 is unaware of the stopped vehicle 316 within lane 306. The moving vehicle 314 is moving generally at the same speed as the user vehicle 310 and the tailgater 312.
In an exemplary flow of steps for the lane condition 300, the method would include the steps of inputting a desired end location 352, a user proceeding along the suggested lane 354, the vehicle system receiving data 360 relating to the stopped vehicle 316 and the tailgater 312. Data relating to the stopped vehicle is communicated to the processor 106 by means of crowdsourcing, the Department of Transportation, and/or vehicle-to-vehicle communications. Data relating to the tailgater 312 is communicated to the processor 106 by means of the external vehicle sensors 114 on the vehicle 310. The processor 106 then determines that an alternate lane should be used. In some embodiments, the system may communicate to the user that the vehicle should switch to the middle lane. Alternatively, the processor may display a warning to avoid the far right lane (i.e. the third lane 306). In other embodiments, the processor may display a warning to avoid the tailgater 312 by switching to the middle lane.

The processor 106 then receives data 460 as illustrated by reference numeral 454. The vehicle system determines that the user vehicle 404 should switch lanes based on the data 460. In this embodiment, the data 460 indicates to the processor 106 that the emergency vehicle 408 is approaching. This information is communicated to the processor 106 by means of vehicle-to-vehicle communication and/or crowdsourcing. The processor then displays/communicates the suggested lane change to the user, such as illustrated by reference numeral 458. The display may be similar to what is illustrated on a dashboard 462: “Warning! Emergency vehicle approaching move to right lane.”

The flowchart 550 illustrates the exemplary steps of the system taken in the lane condition 500. The processor 106 receives 554 data 566 relating to an unplowed road 568, hazardous road conditions 570, and the weather conditions 572. The processor then calculates 556 a lane change to the user of the user vehicle 502. Exemplary displays to the user may include suggestions to change lanes to avoid the pothole and/or to take the exit to avoid the unsavory road conditions 515 and inclement weather 510.
The present system allows the user of the system to find a preferred lane or route when traveling. The system integrates third party data which provides specific information to the system which then determines a preferred route. This provides the advantages that the exact specific lane of travel (or route) can be provided to the user thereby making a more desirable driving experience to the user.
