Abstract
A navigation method is implemented by a group of portable devices which are associated with a map-and-information system and each of which is communicatively coupled to an instrument cluster device of a respective vehicle. The group of the portable devices includes a leader device and at least one follower device. The map-and-information system computes, for the follower device, a dynamic navigation path from the follower device to the leader device. The instrument cluster device of the vehicle that corresponds to the follower device perceivably outputs the dynamic navigation path.
Claims10
A navigation method, comprising:
- A) providing a plurality of portable devices, each of the portable devices having a positioning function to generate a real-time position dataset that indicates a real-time position thereof, being communicatively coupled to an instrument cluster device of a respective one of vehicles, and being associated with a map-and-information system;
- B) establishing, via a network and by the portable devices each of which executes an application program, a device group including a leader device and at least one follower device, wherein a first one of the portable devices is set to serve as the leader device, and each of the portable devices that is other than the first one of the portable devices is set to serve as one of the at least one follower device;
- C) computing, by the map-and-information system and based on a real-time positioning dataset corresponding to the leader device and a real-time positioning dataset corresponding to the at least one follower device, data for a dynamic navigation path from the real-time position of the at least one follower device to the real-time position of the leader device;
- and
- D) perceivably outputting, by the instrument cluster device of one of the vehicles that corresponds to the at least one follower device, the dynamic navigation path based on the data for the dynamic navigation path.
A navigation system, comprising:
- a plurality of portable devices, each of which has a positioning function to generate a real-time position dataset that indicates a real-time position thereof, is communicatively coupled to an instrument cluster device of a respective one of vehicles, each of said portable devices executing an application program to establish, via a network, a device group including a leader device and at least one follower device, wherein a first one of the portable devices is set to serve as the leader device, and each of said portable devices that is other than the first one of said portable devices is set to serve as one of said at least one follower device;
- and
- a map-and-information system configured
- to receive the real-time positioning dataset corresponding to said leader device and the real-time positioning dataset corresponding to said at least one follower device, and
- to compute, based on the real-time positioning dataset corresponding to said leader device and the real-time positioning dataset corresponding to said at least one follower device, data for a dynamic navigation path from the real-time position of said at least one follower device to the real-time position of said leader device;
- wherein said at least one follower device is configured to receive the data for the dynamic navigation path from said map-and-information system, and to cause the instrument cluster device of one of the vehicles that corresponds to said at least one follower device to perceivably output the dynamic navigation path based on the data for the dynamic navigation path.
