Definitions

  • This invention relates to communications and tracking systems that track the location, movement, and destination of vehicles or individuals.
  • Fig. 1 shows a tracking system similar to that described in U.S. patent application No. 5,959,577, which is hereby incorporated by reference in its entirety.
  • the system of Fig. 1 includes multiple mobile units (also referred to herein as rovers) 110.
  • Each rover 110 can be a handheld device that a delivery person carries or a device mounted in a vehicle.
  • Each rover 110 contains a global positioning system (GPS) receiver, a wireless device, and a control circuit.
  • GPS global positioning system
  • the GPS receiver When activated, the GPS receiver receives signals from GPS satellites 120 and from the signal identifies the position (e.g., longitude and latitude) and velocity of a rover 110.
  • the wireless device typically a wireless modem, transmits the position and velocity information via a wireless network 130 and the Internet 150 to a service center 140.
  • Service center 140 receives and collects data from mobile units 110 and makes the collected data available to a user of a terminal 160.
  • Terminal 160 is typically a computer that connects via the Internet 150 to a web site associated with service center 140.
  • the user can view the data or send a query or message to service center 140 for relaying to a specific rover 110.
  • service center 140 sends the query or message to the selected rover 110.
  • the system of Fig. 1 provides a convenient method for a business to track deliveries, the system is generally not accessible to the business' customers who may also be interested in knowing when a delivery will arrive. Additionally, the business expecting an arrival of a vehicle at a particular location such as a loading dock must periodically check the position of the vehicle to determine when the vehicle can be expected. This monitoring may be subject to errors since the vehicle while near the destination may be headed elsewhere. Accordingly, a possible improvement of the system of Fig. 1 would be to provide better information indicating expected arrival time and to provide such information not only to the business but also to customers without requiring the business or customers to constantly poll the position of the delivery vehicles.
  • US6,124,810 discloses a system for determining when a vehicle has arrived or departed from a location.
  • a processor within the vehicle generates an indication or either an arrival or departure directly to a central facility or to a vehicle operator.
  • the system of US6,124,810 does not overcome all of the problems outlined above.
  • an alert generating method comprising: providing to a mobile unit over a wireless network service connection information that identifies conditions for an alert, monitoring in the mobile unit a position of the mobile unit, providing to a service center a signal indicating that the conditions for an alert are satisfied, and alerting a designated location from the service center by sending a message to a recipient at said designated location upon receiving the signal, characterised in that the mobile unit is linked to the Internet by the wireless network service connection, the Internet is linked to the service center, and said message is an email message and is sent to the recipient at said designated location over the Internet.
  • the invention also provides a system for alerting a recipient of a delivery, the system including a mobile unit comprising: a location system, a wireless device linking the mobile unit with a service center over a wireless network connection, and a control circuit wherein the control system automatically activates the location system to determine a current location of the mobile unit, determines whether the mobile unit has crossed a threshold, and activates the wireless device to send an alert signal if the mobile unit has crossed the threshold, wherein the control circuit comprises an alerting device, the service center is connected to the mobile unit over the wireless network connection to enable receipt of messages from the mobile unit and connected to the alerting device to enable the service center to activate the alerting device and send alerts, the service center maintaining contact information for the mobile unit, and in response to a signal from the mobile unit, the service center activates the alerting device to send an alert to a designated location identified in the contact information, characterised in that the mobile unit is linked to the Internet by the wireless network service connection, the Internet is connected to the service center, and the service center sends the alert by
  • a rover may identify a destination or travel threshold, periodically check the rover's location relative to the destination or threshold, and send an alert to a service center upon nearing the destination or crossing the threshold. Accordingly, the service center can alert a designated party when the rover nears a destination or when the rover leaves an alert area surrounding a location.
  • the alerts can be relayed via an automated telephone message, a pager message, an e-mail message, or any other communication means.
  • the alerts can be used for deliveries by directing an alert to a customer expecting a delivery or to a site expecting a vehicle for loading or unloading. In a private context, the alerts can automatically activate systems such as a home appliances or systems in anticipation of a resident's arrival.
  • the conditions for an alert typically include that the mobile unit is headed to a specific destination and is within an alert area surrounding that destination or the mobile unit has entered or left an alert area.
  • the alert can be sent to a telephone, a pager, or an e-mail address.
  • a delivery method may include creating a list of destinations for deliveries.
  • the list includes a threshold distance and other information for one or more destinations for which an alert should be generated.
  • a next destination that a delivery vehicle is headed towards is selected from the list for the delivery vehicle, and the delivery vehicle monitors distance between the delivery vehicle and the selected destination.
  • the delivery vehicle generates an alert when the distance is less than a threshold distance associated with the destination. More specifically, generating the alert may include sending a message from the delivery vehicle to a service center, looking-up a designated location that corresponds to the destination, and sending the alert from the service center to the designated location.
  • the mobile unit may include a location system, a wireless device, and a control circuit.
  • the control system periodically activates the location system to determine a current location of the mobile unit, determines whether the mobile unit has satisfied an alert condition (e.g., has entered or left an alert area), and activates the wireless device to send an alert signal if the mobile unit has satisfied the alert condition.
  • the location system is typically a GPS receiver
  • the wireless device is typically a wireless modem or telephone.
  • the control circuit can determine whether the current location is within the alert area by determining whether a distance between the current location and a central point or destination in the alert area is less than or greater than a threshold distance associated with the alert area.
  • a communication connection may allow the service center to receive messages from a mobile unit, and the alerting device may allow the service center to send alerts.
  • the service center maintains contact information for the mobile unit, and in response to a signal from the mobile unit, the service center activates the alerting device to send an alert to a designated location identified in the contact information.
  • the contact information can be kept at the service center or forwarded from the mobile unit to the service center.
  • the service center is generally Internet accessible to allow multiple, geographically disparate people to set the conditions for an alert and the designated location to which the alerting device sends the alert.
  • a tracking system automatically alerts a designated party before a mobile unit (or rover) arrives at a destination.
  • Fig. 2 illustrates a system 200 implementing alerts in accordance with the invention.
  • System 200 is similar to system 100 described above and includes rovers 210, GPS satellites 120, a wireless network service connection 130, a service center 240, an alerting device 250, the Internet 150, and terminal 160.
  • Rovers 210 and service center 240 of Fig. 2 are similar to rovers 110 and service center 140 of Fig. 1.
  • service center 240 communicates with and tracks multiple rovers 210, as describe above.
  • rovers 210 and service center 240 have additional features for generating impending arrival alerts to designated locations 270. These additional features can be implemented in software or firmware performing the functions described further below.
  • Each rover 210 includes a communications package such as the iLM 2000 available from @Road, Inc.
  • the communications package includes a GPS receiver 212, a control circuit 214, and a wireless device 216.
  • GPS receiver 212 when activated interprets signals from GPS satellites 120 to identify the position and velocity of the rover 110.
  • Control circuit 214 has a user interface including a keyboard or other input device for operator control of the communications package, a display or another output device for conveying information such as the status of the package and received messages, and a processing circuit.
  • the processing circuit implements automated operation and commands from the operator or from service center 240.
  • Wireless device 216 and service connection 130 handle communications between service center 240 and rovers 210.
  • Connection 130 can be any wireless service, whether analogue or digital, which supports data transfers between service center 240 and rover 210.
  • the communication can operate through a CDPD, AMPS, CDMA, GSM, or Nextel system, using both OEM modem modules internal to the rover or cellular phones that are separable from the rover and attached to the remainder of the communication package via a data cable.
  • the communications package could use a removable or separate cellular telephone, this is not the ideal solution since removing the telephone disables the connection between the communications package and service center 240.
  • the wireless service 132 preferably offers packetized data and direct connection to the Internet because these capabilities facilitate sporadic data transfers between rovers 210 and service center 240 with least use of the wireless resources and therefore the least cost to the operator of the communications package.
  • Fig. 3 is a flow diagram of a method 300 of generating impending arrival alerts in accordance with an embodiment of the invention.
  • An initial step 310 of method 300 is creation of a destination list that can be forwarded or downloaded to service center 240 and/or rover 210.
  • Each rover 210 has a destination list, which contains a set of destination entries corresponding to the intended destinations of the rover 210.
  • the Appendix contains a C-language data structure for one embodiment of a destination list.
  • Each destination entry includes a location (e.g., an address or longitude and latitude of a destination), an alert condition, contact information for the alert or alerts, and any other information related to the destination, the alert, or the contact.
  • the Service center 240 can easily convert an address provided in a destination list to longitude and latitude values, which are commonly used in GPS systems.
  • the alert condition typically includes threshold information, which is typically a distance or radius that defines an alert area around the destination.
  • the alert condition may additionally include fields indicating circumstances for the alert. Typical circumstances surrounding an alert include whether the alert should be sent at all, a direction of traversal of the threshold that triggers an alert, an order of the destinations, and any time limitations on the alert.
  • the contact information identifies designated location 270 and the method for contacting location 270 when an issuing an alert.
  • the contact information can include, for example, a telephone number, a pager number, or IP address and port.
  • the destination list can be maintained in service center 240 or rover 210 or a combination of the two.
  • keeping and manipulating the destination list at service center 240 has advantages.
  • a central dispatcher through terminal 160 and data connection 150 can organize destinations into an ordered destination list and download the list to service center 240.
  • service center 240 is ideally Internet based, multiple people could access and manage the destination list via the Internet 150, even after rovers 210 have started their routes. End customers, who are anticipating a delivery, could also be given limited access to their destination entry to determine an estimated arrival time, schedule an alert immediately before arrival at their address, or change the contact information.
  • the service center can also provide a telephone or e-mail interface for creating, changing, or reviewing a destination list.
  • Each destination entry is at least partially downloaded to rover 210, so that rover 210 at least has the destination and threshold information for the next destination.
  • the destination location can be latitude and longitude (probably from geocoding the street address) as used in the GPS receiver.
  • rover 210 does not require the contact information, but other information may be useful in rover 210.
  • text sent to rover 210 could indicate any information related to the destination, for example, a destination name and address that permits a driver/operator to more readily identify destinations when scrolling through the destination list.
  • An appointment time associated with a destination provides the driver additional information for scheduling of deliveries.
  • Additional fields used by control circuit 214 in the communications package can indicate whether to generate an alert when the rover 210 crosses into the alert area, out of the alert area, or both.
  • an alert is generated when rover 210 moves into the alert area to indicate an impending arrival.
  • an alert can also be generated when rover 210 leaves an alert area indicating rover 210 is headed elsewhere, for example, possibly indicating that rover 210 is outside its intended range and may have been stolen or misdirected.
  • Other information that can be included with a destination entry indicates an expiration time (when the entry is automatically deleted whether or not one or more alerts were generated), whether the entry should auto-delete after an alert is sent or is retained until its expiration time, and alternate contact information that may be indexed for use at different times.
  • step 320 when rover 210 begins heading to the next destination, the operator/driver of rover 210 selects that destination for use in generating alerts. In particular, some alerts may only be issued if the alert is for the next destination. Other alerts could be issued regardless of the next destination.
  • the rover informs service center 240 of the selection.
  • the selection of the destination can be automatic according to the order in the destination list or subject to the choice and judgement of the driver. If the list is downloaded to the rover 210 instead of being managed exclusively at service center 240, the in-vehicle system can display candidate destinations for the driver's selection.
  • the driver may override the order of destinations in the destination list because of traffic or other reasons not anticipated by the list's creators. Where the driver overrides the order, the rover 210 can send a message directing the service center to update the destination list to reflect the new order and update estimates of delivery times. The driver could even create new entries, although the limits of the user interface available on an in-vehicle system might make this difficult.
  • service center 240 in step 330 confirms the next destination and instructs the rover 210 to keep checking the location until rover 210 an alert condition is met, e.g., the rover enters an alert area for the selected destination. If necessary, service center 240 supplies a location for the selected destination and the alert conditions during step 330, but that information may have been previously downloaded into rover 210.
  • rover 210 determines whether rover 210 has crossed the boundary of the alert area.
  • the appendix includes functions that record route hysteresis to determine whether a boundary has been crossed and whether the crossing direction is into or out of to the area within the boundary.
  • the rover determines whether the rover has crossed from a distance from the destination that is greater than the bounding radius to a distance from the destination that is less than the threshold radius.
  • Other more complicated threshold area descriptions could also be used.
  • the alert condition could identify an alert area other than a circle or include some variations based on the current or recent average speed of rover, but such identifications could significantly complicate the required calculations in rover 210.
  • a decision step 350 determines whether rover 210 reached the threshold for an alert. If not, rover 210, typically after a delay, again determines whether it has reached the threshold for an alert.
  • rover 210 in step 350, when rover 210 determines that it has crossed the threshold in the target direction, rover 210 in step 360 sends an alert to service center 240.
  • service center 240 forwards the alert to designated location 270 using the contact information from the destination list.
  • the designated location 270 can be the destination or to another location. For example, if the destination is a customer's home and the designated location 270 is the customer's work address, the customer upon receiving the alert can return home to accept the delivery. As noted above, the designated location 270 can change according to factors such as the time.
  • alerting device 250 is a communication device such as an automated telephone messaging system or an automated e-mail system.
  • the alerted party can be alerted in a variety of ways, including but not limited to by e-mail, paging message, text message to a cellular phone, or a telephone call with a synthesized speech or recorded message.
  • Method 300 can be widely varied without departing from the scope of the invention.
  • rovers 210 can keep their own destination lists.
  • the communications device in the rover accesses threshold and contact information in the stored on board in the destination list.
  • step 360 when rover 210 sends an alert to service center 240, the rover forwards the contact information for designated location 270, and service center 240 forwards the alert to the designated location 270.
  • a rover 210 sends an alert whenever the rover is near particular destinations regardless of whether any of these destinations is the next destination.
  • the rover in step 340 compares the current location to the location and threshold information of all destinations that are eligible for alerts, and in step 350 decides to issue an alert if conditions for the alert are met.
  • a rover can issue an alert if the rover leaves a designate area or range from its base location (indicating perhaps that the rover is misdirected or stolen).
  • Each destination entry can include a tag number that identifies the destination, and the rover 210 incorporates the tag number in the alert message sent to service center 240. From the tag number, service center 240 decides where (e.g., which designated location) and how to send the alert.
  • the alerted party might be the truck dispatcher (for example, to alert the dispatcher that a truck is returning to base or that the truck has crossed a perimeter, heading away, and might be stolen).
  • Service center 240 can forward an alert from a rover 210 to multiple designated locations, for example, to a customer, and to the dispatcher to alert the dispatcher as to the progress of their drivers.
  • Arrival alerting systems such as described above can be employed in a variety of applications.
  • an alert indicating an impending arrival allows a delivery manager to deploy resources to a particular loading bay, and even to call ahead to the driver tell them which bay has been allocated for the delivery.
  • the site manager can ready loading/unloading equipment and people, to minimize turn-around time.
  • resources are not wasted waiting for arrival, and time is not consumed periodically polling the position of the truck.
  • the alert can go to a location other than the destination, for example, to alert a consumer at work or via the consumer's pager that an impending delivery is destined for the consumer's home. If the consumer is near enough to home, the consumer can return home to meet the delivery or ask the delivery driver to wait.
  • Another consumer application is automated activation of household equipment such as heating or cooling systems or appliances when the resident nears home. Energy can be saved by leaving heating and cooling systems in a low power mode while the resident is away and activating the system so that the home is at a comfortable temperature when the resident arrives. Alternatively, an alert can activate a coffeepot so that the resident has freshly brewed coffee when arriving home.
  • the full range of applications of the invention is of course not limited to these few examples.
  • This appendix contains listings for functions and data structures in C programming language, for use in a rover in an embodiment of the invention such as described above.
  • the functions typical would be periodically executed in a rover to check any alert conditions of entries in a proximity queue and update the proximity queue to remove expired entries.
