Navigation system and controlling method for the motor vehicle
First Claim
1. A navigation system for use in a mobile object, comprising:
- a transceiver unit for transmitting a signal for demanding a detection of a navigation path, which is a short-cut path or an optimum path from a departure point to a destination, to a path detecting server via a wireless network and then receiving path data which represents the navigation path from the path detecting server via the wireless network;
a display unit for outputting the navigation path or a revised navigation path;
an input unit for inputting data on the departure point and the destination; and
an electronic control unit (ECU) for transferring the data on the departure point and the destination from the input unit to the transceiver unit, transferring the path data from the transceiver unit to the display unit, precalculating deviation-expected path data which represent one or more deviation-expected paths in the course of driving along the navigation path, storing the one or more deviation-expected paths in a memory of the navigation system installed in the mobile object before the mobile object deviates from the navigation path, and selecting revised path data which represent the revised navigation path, among the one or more precalculated deviation-expected paths stored in the memory to thereby provide the revised navigation path to the display unit after a present position of the mobile object deviates from the navigation path,wherein the one or more deviation-expected paths are precalculated based on nodes and links connecting the nodes between the departure point and the destination.

Abstract
A navigation system (20) includes a transceiver unit (210), a display unit (250), an input unit (260) and an ECU (230). The transceiver unit (210) transmits a signal for demanding a detection of a navigation path to a path detecting server (10) and then receives path data which represent the navigation path from the path detecting server (10). The display unit (250) outputs the navigation path or a revised navigation path. The ECU (230) conveys data on a departure point and a destination from the input unit (260) to the transceiver unit (210) and transfers the path data from the transceiver unit (210) to the display unit (250). Further, the ECU (270) precalculates deviation-expected paths in the course of driving along the navigation path and selects the revised navigation path among the precalculated deviation-expected paths in case a present position of a mobile object deviates from the navigation path to thereby provide the revised navigation path to the display unit (250).

6. A method of navigating a mobile object traveling from a departure point to a destination by use of a navigation system installed in the mobile object, comprising the steps of:
-
(a) transmitting a signal for demanding a detection of a navigation path, which is a short-cut path or an optimum path from the departure point to the destination, to a path detecting server via a wireless network; (b) receiving path data which represent the navigation path from the path detecting server via the wireless network; (c) displaying the navigation path in response to the received path data; (d) the navigation system precalculating deviation-expected path data which represent one or more deviation-expected paths, and storing the one or more deviation-expected paths in a memory of the navigation system installed in the mobile object before the mobile object deviates from the navigation path; (e) selecting revised path data, which represent a revised navigation path, among the one or more precalculated deviation-expected paths stored in the memory to thereby provide the revised navigation path to a display unit after a present position of the mobile object deviates from the navigation path; and (f) displaying the revised navigation path in response to the revised path data, wherein the one or more deviation-expected paths are precalculated based on nodes and links connecting the nodes between the departure point and the destination at the step (d). - View Dependent Claims (7, 8, 9, 10)
