System and method for hybrid off-board navigation
First Claim
1. A method of off-board navigation, comprising:
- receiving, at a navigation device, routing information relating to a route from a starting point to a destination;
tracking a location of the navigation device;
detecting an off-route condition in which the location of the navigation device has departed from the route;
sending, from the navigation device to a server, a route request message including the location of the navigation device and vehicle attributes, the vehicle attributes being related to a vehicle associated with the navigation device;
detecting an availability of a response from the server to the route request message; and
if the response is detected as being available;
receiving a route correction message from the server, the route correction message including a multi-stop route to the destination based on the location of the navigation device, the vehicle attributes provided by the navigation device, and a set of fleet rules associated with a plurality of vehicles including the vehicle associated with the navigation device,wherein the vehicle attributes include one or more of a vehicle height, a vehicle weight, and load restrictions, andwherein the multi-stop route is further based on expected changes to one or more of the vehicle attributes during transit; and
updating a portion of the route at the navigation device based on the route correction message.

Abstract
A system, method and apparatus for hybrid off-board vehicle navigation are disclosed. In the system, a multi-stop route package is created and sent from a route server to a navigation device. The route package can include a collection of vehicle attributes and corresponding road restrictions for guiding the vehicle towards its destination. The server can optionally push the route package to the vehicle in an email message or other stored communication. When an off-route condition is detected, the navigation device can send a route request to the server that includes the vehicle attributes and the corresponding road restrictions. The server can respond with a partial route correction that is determined based on the vehicle attributes and road restrictions.

11. A navigation device, comprising:
-
a network interface configured to receive from a source external to the navigation device route data relating to a route; a memory configured to store the route data; a positioning module configured to determine a current position of the navigation device in relation to the route; a display configured to provide route guidance to a user of the navigation device; and a routing engine configured to; determine the route guidance according to the route data and to detect an off-route condition based on the current position of the navigation device; send a route request message comprising vehicle attributes from the navigation device to a server via the network interface, the vehicle attributes being related to a vehicle associated with the navigation device; detect the availability of a response from the server to the route request message; obtain route correction information from the response when the response from the server is available, the route correction information including a multi-stop route to the destination based on the vehicle attributes and a set of fleet rules associated with a plurality of vehicles including the vehicle associated with the navigation device, wherein the vehicle attributes include one or more of a vehicle height, a vehicle weight, and load restrictions, and wherein the multi-stop route is further based on expected changes to one or more of the vehicle attributes during transit; and update the route data at the navigation device based on the route correction information, the route correction information based partly on the vehicle attributes provided by the navigation device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 21)

19. A method comprising:
-
tracking a location of a navigation device; sending, from the navigation device to a server, a route request message including a desired destination, the location of the navigation device, and vehicle attributes, the vehicle attributes being related to a vehicle associated with the navigation device; receiving a route response message from the server, the route response message including a multi-stop route to the destination based on; the location of the navigation device; a set of fleet rules associated with a plurality of vehicles including the vehicle associated with the navigation device; and the vehicle attributes provided by the navigation device, wherein the vehicle attributes include one or more of a vehicle height, a vehicle weight, and load restrictions, and wherein the multi-stop route is further based on expected changes to one or more of the vehicle attributes during transit; and updating a portion of the route at the navigation device based on the route response message. - View Dependent Claims (22)
