Embodiment 1
[0028] like figure 1 As shown, it is a schematic flow chart of the navigation method in Embodiment 1 of the present invention, and the navigation method may include the following steps:
[0029] Step 101: Determine whether the user deviates from the navigation route according to the current location of the navigation terminal.
[0030] Step 102: If it is determined to deviate from the navigation route, select a location point on the navigation route other than the destination as a home point for returning to the navigation route.
[0031] Step 103: Determine the return route from the current position of the navigation terminal to the return point.
[0032] Step 104: Use the return route and the route between the return point and the destination on the navigation route as a new navigation route to guide the user to the destination.
[0033] Generally, if the user travels by car, the user will learn about the navigation route after obtaining the navigation route, and will have...
Embodiment 2
[0116] like image 3 As shown, the navigation method in the embodiment of the present invention is described by deviating from the navigation route after obtaining the navigation route through online navigation, and the method includes the following steps:
[0117] Step 301: The navigation terminal performs positioning to obtain the current location.
[0118] Step 302: Determine whether the user deviates from the navigation route according to the current location of the navigation terminal.
[0119] Step 303: Obtain the road attribute of the road where the yaw point is located.
[0120] Step 304: Determine whether the road attribute is a preset road attribute; if yes, execute step 305; if not, execute step 306.
[0121] Step 305: On the route that the navigation terminal has not passed in the navigation route, determine that the road segment within the first preset distance to the second preset distance from the yaw point is the sampling road segment, and then execute step 3...
Embodiment 3
[0143] Based on the same inventive concept, the embodiment of the present invention also provides a navigation device, such as Figure 4 Shown is a schematic diagram of the navigation device, which includes:
[0144] Off course determination module 401, configured to determine whether the user deviates from the navigation route according to the current position of the navigation terminal;
[0145] The home point selection module 402 is used to select a location point other than the destination on the navigation route as the home point for returning to the navigation route if it is determined to deviate from the navigation route;
[0146] The return route determination module 403 is used to determine the return route from the current position of the navigation terminal to the return point;
[0147] The navigation route synthesis module 404 is configured to use the return route and the route between the return point and the destination on the navigation route as a new navigatio...
