COPYRIGHT AUTHORIZATION

Portions of the disclosure of this patent document may contain material which is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the U.S. Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.


BACKGROUND AND SUMMARY

Systems and methods are disclosed for determining an optimal path and/or route to a destination for a vehicle. More specifically, in some embodiments, systems and methods are described for determining an optimal charging path and/or route to a destination for an electric vehicle (“EV”) and a reservation generation system for use in connection with the same.


When operating a vehicle, it is often desirable to optimize the total travel time and/or cost associated with arriving at a desired destination. Vehicles, however, may have a limited range before an energy source used to power the vehicle is depleted. Once the energy source is depleted, a refueling and/or recharging operation may be needed for the vehicle to continue operation. Accounting for inherent limitations in vehicle energy sources may allow for better optimization of vehicle travel times and/or costs.


In a hybrid-electric vehicle (“HEV”), a plug-in hybrid electric vehicle (“PHEV”), a fuel cell electric vehicle (“FCEV”), and/or a purely electric vehicle (“EV”), a battery system may be used to power electric drivetrain components of the vehicle (e.g., electric drive motors and the like). Vehicle battery systems may have limited charge capacities, lengthy recharging times, and/or be limited for use in connection with relatively sparse charging infrastructures. A variety of other types of vehicles (e.g., natural gas vehicles, conventional internal combustion engine vehicles, fuel cell vehicles, etc.) may have similar limitations and require periodic refueling. Accordingly, it is desirable to strategically plan a trip to a desired destination that takes into account vehicle charging and/or fueling requirements.


Embodiments of the systems and methods disclosed herein facilitate intelligent route planning to a desired destination by a vehicle. In certain embodiments, systems and methods are provided that allow for determination of a path and/or route (e.g., an optimal route) to a desired destination that accounts for vehicle charging and/or refueling requirements. In certain embodiments, a variety of routing parameters may be utilized in determining a path and/or a route to a desired destination. For example, vehicle charge and/or fuel capacities, charging and/or refueling times, charging and/or refueling infrastructure compatibility and availability, energy source pricing, geographic and environmental factors (e.g., traffic conditions, elevation changes, average historical travel times along routes, etc.), consumer ratings, and/or any other relevant parameter or parameters may be utilized in connection with determining an optimal route of a vehicle to a desired destination.


In some embodiments, a variety of possible routes to a desired destination based on available routing parameters may be presented to a user of a vehicle. A user may select a route from the identified routes and be provided with directed driving instructions associated with the selected route to the destination (e.g., via turn-by-turn directions or the like). In further embodiments, an optimal route may be automatically selected and/or recommended to a user based on a calculated cost associated with the route. In certain embodiments, the calculated cost may account for a variety of factors including, without limitation, travel time along the route, predicted energy usage along the route, pricing at recharging and/or refueling stations along the route, and/or any other relevant routing parameter associated with the route. Automatically selecting and/or presenting a user with a recommended optimal route may allow for a shorter, more efficient, and/or less expensive journey to a desired destination in an associated vehicle.


Further embodiments disclosed herein may implement targeted information delivery services (e.g., targeted advertising, targeted promotions, etc.) in connection with intelligent route planning. For example, interests and/or other personal information associated with a user may be utilized to identify one or more points of interest (“POI”) proximate to an identified route that the user may have an interest in visiting during the journey to his or her destination. The identified POIs, associated targeted advertisements, offers, and/or other information may be presented to a user in connection with one or more identified routes. Using such information, a user may select a route having nearby POIs that they may wish to visit on their way to a desired destination. In further embodiments, identified POIs may be utilized in connection with calculating costs associated with a particular route for use in selecting and/or recommending an optimal route.

In certain embodiments, the vehicle 100 may be communicatively coupled with a telematics service provider system 114. The telematics service provider system 114 may operate in conjunction with the telematics system 106 included in the vehicle 100 to provide telematics-related services to a user of the vehicle 100. Among other functions, the telematics service provider system 114 may provide navigation-based services, traffic, weather and travel information services, location and/or POI information and/or recommendation services, and/or the like. For example, the telematics service provider system 114 may operate with the telematics system 106 included in the vehicle 100 to provide geographic mapping services using information included in a map database 120 stored and/or maintained by the telematics service provider system 114. The telematics service provider system 114 and/or telematics system 106 may further provide traffic information services using traffic information 122 and/or POI information services using location and/or POI information 126 stored and/or maintained by the telematics service provider system 114. In certain embodiments, services provided by the telematics service provider system 114 may interact with one or more third-party service providers to facilitate the provision of services (e.g., third-party mapping services, traffic information services, POI information services, etc.).


In some embodiments, the telematics service provider system 114 and/or the vehicle 100 may be communicatively coupled with a charging station service provider system 116. The charging station service provider system 116 may interface with an infrastructure of one or more charging stations 128 configured to supply energy to the vehicle 100. In certain embodiments, the charging station service provider system 116 may be associated with a single charging station infrastructure network (e.g., Chargepoint® or the like). In further embodiments, the charging station service provider 116 may be associated with a plurality of charging station infrastructure networks.


The charging station service provider system 116 may provide a variety of information regarding charging stations 128 in communication therewith. For example, the charging station service provider system 116 may maintain station information 130 regarding the connected charging stations 128. The station information 130 may, for example, comprise, among other things, information regarding types of connected charging stations 128 (e.g., charging station connectivity or the like), charging station capabilities, ratings of connected charging stations 128 (e.g., user reviews or ratings or the like), station location information, charging station operating hours, pricing of energy provided by connected charging stations 128 (e.g., on/off peak rates or the like), and/or any other information relating to the charging stations 128.


In further embodiments, the charging station service provider system 116 may maintain information relating to the availability of connected charging stations 128. For example, the charging station service provider system 116 may maintain information regarding a reservation schedule 132 for one or more connected charging stations 128. Among other things, the reservation schedule 132 may comprise information indicating current and/or future availability of connected charging stations 128, current and/or future reservation information relating to the stations 128, user information associated with reservations, and/or any other information pertaining to the use and/or availability of connected charging stations 128.


The reservation schedule 132 may be maintained and/or generated by a station reservation engine 134. The station reservation engine 134 may provide a variety of reservation related functions. For example, the station reservation engine 134 may interact with users and/or other systems in connection with generating reservations, changing reservations (e.g., moving, cancelling, etc.), usage billing, and/or any other function relating to the connected charging stations 128.


Station information 130 and/or reservation schedules 132 may be communicated to a variety of connected systems (e.g., systems of vehicle 100 and/or telematics service provider system 114). Consistent with embodiments disclosed herein, the telematics service provider system 114 and/or telematics system 106 may facilitate intelligent route planning to a desired destination by the vehicle 100 using, at least in part, such information.


In some embodiments, the telematics service provider system 114 and/or the telematics system 106 may identify one or more routes to a desired destination based on one or more available routing parameters. For example, a route determination engine 124 associated with the telematics service provider system 114 may utilize route parameter information provided by the vehicle 100 and/or the charging station service provider system 116, information maintained by the telematics service provider system 114, and/or information provided by one or more third parties (e.g., weather and/or traffic reporting services, mapping services, etc.). In certain embodiments, such route determination may account for vehicle charging and/or refueling requirements.


Routing parameters utilized in identifying one or more routes to a destination may generally include information relating to the vehicle, information relating to an environment of the vehicle, information relating to an associated charging and/or refueling infrastructure, and/or the like. For example, suitable routing parameters used in identifying one or more routes may comprise, without limitation, vehicle charge and/or fuel capacities and/or reserves, charging and/or refueling times, charging and/or refueling infrastructure locations, pricing, compatibility and availability, geographic and environmental factors (e.g., travel distances, traffic conditions, elevation changes, average historical travel times along routes, weather, etc.), consumer ratings, locations of relevant POIs, and/or any other relevant parameter or parameters that may be utilized in connection with determining an optimal route of a vehicle to a desired destination. It will be appreciated that a variety of other types of routing parameters may be utilized in connection with route identification, and that any information that may influence route identification decision processes may be used in connection with the disclosed embodiments.


In some embodiments, a variety of possible routes to a desired destination based on available routing parameters may be presented to a user of a vehicle 100. A user may select a route from the identified routes and be provided with directed driving instructions associated with the selected route to the destination (e.g., via turn-by-turn directions or the like provided by the telematics system 106). In further embodiments, an optimal route may be automatically selected and/or recommended to a user based on a calculated cost associated with the route, as, for example, discussed in more detail below in reference to FIG. 2.


When a route is selected (e.g., automatically selected or selected by a user of the vehicle 100), information regarding the selected route may be communicated to the telematics service provider system 114 and/or the charging station service provider system 116. Based on the information, the charging station service provider system 116 (e.g., the station reservation engine 134) may generate and distribute reservation information to one or more charging stations 128 associated with the selected route. In certain embodiments, generating and distributing reservation information to one or more charging stations 128 may ensure charging station 128 availability as the vehicle 100 travels along the selected route. Reservation generation in response to route selection is discussed below in more detail in reference to FIG. 3.


In certain embodiments, systems and methods disclosed herein may account for variable rate pricing models based on-peak and/or off-peak electric power resource utilization. Such pricing models may be used in route cost determinations. For example, a user of vehicle 100 may begin a 200 mile journey at 7:30 AM. The vehicle battery may be charged to 100% capacity and have an average range of 130 miles per charge under existing driving conditions. Based on a distance to the destination, the vehicle's range, locations of charging stations 128, and/or other factors, it may be determined that the vehicle 100 will need to charge two times so as to leave sufficient battery charge to start a return journey. Options for first charging stations locations may be, for example, located 90 miles and 110 miles into the journey. A calculated time of arrival at the charging station located 90 miles away may be approximately 8:53 AM and may be 9:11 AM at the charging station located 110 miles away. If off-peak discounted electricity rates extend to 9:00 AM, the cost of the journey may be reduced by selecting the charging station 90 miles away.


It will be appreciated that a number of variations can be made to the architecture and relationships presented in connection with FIG. 1 within the scope of the inventive body of work. For example, certain system functionalities described above (e.g., functionalities of vehicle 100 systems, telematics service provider system 114, and/or charging station service provider system 116) may be integrated into a single system and/or any suitable combination of systems in any suitable configuration. Similarly, it will be appreciated that although discussed in reference to an electrical charging station network for a vehicle 100 powered by a battery system, embodiments of the systems and methods disclosed herein may be implemented in a variety of other vehicle energy source charging and/or fueling infrastructures (e.g., gasoline infrastructures, diesel infrastructures, fuel cell infrastructures, natural gas infrastructures, etc.). Thus it will be appreciated that the architecture of FIG. 1 is provided for purposes of illustration and explanation, and not limitation.



FIG. 2 illustrates a diagram showing exemplary vehicle route determination and scoring consistent with embodiments of the present disclosure. Particularly, FIG. 2 illustrates a plurality of identified routes (i.e., Route 1, Route 2, and Route 3) for the vehicle 100 to arrive at a desired destination 200.


In certain embodiments, a user of a vehicle 100 may indicate his or her desire to travel to a destination 200 (e.g., via a telematics system or another suitable system). Based on a variety of available routing parameters, one or more routes to the desired destination 200 may be identified. For example, a determination may be made that, based on an amount of charge remaining in the vehicle 100, the vehicle may travel a certain distance before needing to be recharged. One or more charging stations may be identified within a range corresponding to the distance the vehicle 100 can travel before needing to be recharged, and one or more routes may be identified associated with the one or more charging stations within range of the vehicle 100. For example, as illustrated, charging stations 202-206 may be within range of the vehicle 100 and, accordingly, may be utilized as an intermediate charging stop on routes to the destination 200 (i.e., Routes 1-3). Charging station 212 may be out of range of the vehicle 100, however, and thus may not be utilized as an intermediate charging stop in route identification operations.


If additional intermediate charging stops are required for the vehicle 100 to reach the desired destination 200 (e.g., as determined by a range of the vehicle 100 after charging), one or more additional intermediate charging stations along associated routes to the destination 200 may be identified. Accordingly, in some circumstances, identified routes may be associated with a plurality of intermediate charging stops corresponding to particular charging station locations. For example, as illustrated, Route 1 may include intermediate stops at charging stations 202 and 208, Route 2 may include intermediate stops at charging stations 204 and 208, and Route 3 may include intermediate stops at charging stations 206 and 210.


As discussed above, a variety of routing parameters may be utilized in connection with identifying routes and/or intermediate stops associated with routes. In certain circumstances, travel ranges of the vehicle used in identifying intermediate charging stops may be dynamically adjusted based on a variety of available parameters. For example, elevation changes, weather along routes, traffic conditions, and/or any other parameter may affect the effective range of the vehicle 100. Accordingly, in estimating a range of the vehicle 100 and identifying associated charging station locations along routes, a variety of routing parameters may be used.


In certain embodiments, each route may have an associated cost that may be calculated (e.g., calculated by a telematics service provider system and/or a route determination engine executing thereon). In some embodiments, an optimal route may be automatically selected and/or recommended to a user based on the calculated cost associated with the route. Calculated costs or routes may account for a variety of factors including, without limitation, some or all of travel time along the route, predicted energy usage along the route, pricing at recharging and/or refueling stations along the route, scenic value of along the route, any/or any other relevant routing parameter associated with the route. In certain embodiments, relative importance and/or weights of such factors may be set by a user for use in calculating route costs. Automatically selecting and/or presenting a user with a recommended optimal route based on a route cost determination may allow for a shorter, more efficient, and/or less expensive journey to the desired destination 200 by vehicle 100.


Each leg of a route may have an associated calculated cost (e.g., each leg between intermediate stops along the route). The total cost of a route may be associated with the sum of the calculated costs of its constituent legs. For example, as illustrated in FIG. 2, Route 1 may have a first leg between the vehicle's origin point and the location of charging station 202 having a calculated cost of “3”, a second leg between the location of charging station 202 and the location of charging station 208 having a calculated cost of “5”, and a third leg between the location of the charging station 208 and the destination 200 having a calculated cost of “3”. Accordingly, the total calculated cost of Route 1 may be “11”. Route 2 may have a total calculated cost of “10” and Route 3 may have a total calculated cost of “13”. Accordingly, Route 2 may be automatically selected and/or recommended to a user of the vehicle 100 as the optimal route for reaching destination 200.


In certain embodiments, a user may adjust the relative importance and/or weights of factors used to calculate costs associated with identified routes, thus adjusting identified optimal routes. For example, a user may indicate they wish to place greater importance on the scenic value of routes to their desired destination 200 (e.g., based on information included in a database providing route scenic value information, ratings, etc.). Based on such an indication, optimal routes may be presented to the user based on their scenic value.


It will be appreciated that a wide variety of parameters and/or user preferences may be utilized in calculating and comparing costs associated with a route and/or its constituent legs, and that any information that may influence identification of an optimal route to a user may be used in connection with the disclosed embodiments. Moreover, although cost-optimization methods are used in some of the illustrated embodiments of identifying optimal routes for traveling to a desired destination, other techniques for determining an optimal route may also, or alternatively, be used, including, for example, techniques using machine-learning methods and processes.



FIG. 3 illustrates an exemplary architecture for generating one or more charging station reservations 306, 308 based on a selected vehicle route consistent with embodiments of the present disclosure. Systems and methods disclosed herein may be utilized in connection identifying one or more routes to a destination 200 for a vehicle 100 (e.g., one or more optimal routes to the destination). In certain circumstances, identified routes may include one or more intermediate stops for charging of vehicle 100. For example, as illustrated in FIG. 3, the vehicle 100 may stop at intermediate locations associated with charging stations 300 and 302 to perform charging operations en route to destination 200.


In some embodiments, a route may be selected by a user or automatically be selected based on being identified as an optimal route to the destination using the optimization techniques described herein. Once a route is selected, route selection information 304 may be communicated to the charging station service provider system 116 and/or another suitable system. For example, in some embodiments, the route selection information 304 may be communicated to the charging station service provider system 116 directly from the vehicle 100 (e.g., from a vehicle telematics system). In other embodiments, the vehicle 100 may communicate route selection information 304 to an intermediate system (e.g., a telematics service provider system or the like) which may communicate the route selection information 304 to the charging station service provider system 116. Thus, it will be appreciated that the route selection information may be communicated and stored in any suitable manner.


The route selection information 304 may comprise information identifying one or more charging stations 300 and 302 along the selected route. The route selection information 304 may further comprise information that may be utilized in determining and/or estimating when the vehicle 100 will arrive at the one or more charging stations 300 and 302. For example, the route selection information 304 may comprise one or more estimated arrival times at the one or more charging stations 300 and 302 during the vehicle's journey to destination 200. The route selection information 304 may further comprise one or more estimates of the amount of time the vehicle 100 will need to be at a charging station (e.g., including an estimate of the amount of time needed to wait for a charging station to become available, and the amount of time needed to actually charge the vehicle's battery).


Based on the route selection information 304, the charging station service provider system 116 and/or a station reservation engine 134 executing thereon may generate and distribute reservation information 306, 308 to charging stations 300, 302 and update a station reservation schedule 132 view of the reservation information 306, 308. By generating and distributing reservation information to charging stations 300, 302, availability of the charging stations 300, 302 may be ensured when the vehicle arrives at the charging stations 300, 302 for recharging operations.


In certain embodiments, the charging station service provider system 116 and/or a station reservation engine 134 may receive updated information as the vehicle 100 progresses along the route that may adjust certain estimated arrival times at charging stations 300, 302. For example, the vehicle 100 may experience unexpected traffic delays that may delay the times at which the vehicle 100 is estimated to arrive at charging stations 300, 302. Accordingly, updated reservation generation information may be generated and distributed to charging stations 300, 302 reflecting updated arrival times. In this manner, availability of the charging stations 300, 302 may be ensured even if estimated arrival times and/or conditions change as the vehicle 100 progresses along the route.
