Route guidance method of navigation device for elderly person {METHOD OF GUIDING A ROUTE IN NAVIGATION APPARATUS FOR AGED PERSON}

The present invention relates to a route guidance method of a navigation device, and more particularly, to a route guidance method of a navigation device for the elderly to guide the route that can be comfortable driving to the elderly to avoid lane changes and left turn.

A typical navigation system is a device that displays the current position of a moving object calculated using information received from a GPS satellite on a map displayed on a display screen. In addition, the navigation system displays various information necessary for driving such as displaying the moving direction of the moving object, the distance to the destination to be traveled, the current moving speed of the moving object, the route set before the driver, the optimum route to the destination, and the like. To provide. Currently, various kinds of moving objects such as ships, aircrafts, automobiles, etc. are widely used because they are equipped with the navigation system (or GPS positioning device) for checking the current position and moving speed or determining the moving path.

Such a navigation system receives radio waves representing latitude, longitude, and altitude from a plurality of satellites belonging to the Global Positioning System (hereinafter referred to as "GPS"), calculates the current position of the moving object, and then calculates the current position of the moving object. The map information included can be visually displayed to the driver or informed to the driver.

On the other hand, the number of senior citizens who drive a vehicle directly is increasing in the aging society. These older drivers tend to be very reluctant to drive, such as lane changes or unprotected left turns, because of their relatively slow judgment and response.

Accordingly, the navigation device is required to provide a navigation guide that can provide driving convenience and psychologically safe driving to the elderly, rather than the general road guidance service of the navigation device that guides the shortest distance or the minimum time route. have.

The present invention is to solve the technical problem to provide a route guidance method of the navigation device for the elderly to guide the elderly to the comfortable driving route to the elderly.

Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings. However, embodiments of the present invention may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below. The embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art. Accordingly, it should be noted that the shapes, sizes, etc. of the components shown in the drawings may be exaggerated for clarity.

1 is a flow chart of a route guidance method of a navigation device for the elderly according to an embodiment of the present invention.

As shown in FIG. 1, the route guidance method of the navigation apparatus for the elderly according to an embodiment of the present invention includes a step (S11) of receiving a destination largely, and the destination being preset from a preset downtown or a current location. Determining whether the short-range destination is less than the reference distance (S13) and if the destination is the downtown or the short-range destination, minimizing the left turn and finding a right turn path that is a path that can reach the destination through the right turn (S14) It may be configured to include.

In addition, one embodiment of the present invention may further include a step (S12) of selecting whether to perform the step (S13) and step (S14) of the right-turn only mode.

In addition, an embodiment of the present invention compares the estimated time taken to reach the destination by the right turn route and the estimated time taken to arrive at the destination by the route found differently (S15) and the Guiding the right turn route when the difference between the estimated time taken to reach the destination by the right turn route and the estimated time taken to arrive at the destination by the route found in a different way is smaller than a preset time (S16). ) May be further included.

2 is a flowchart illustrating a destination dictionary input step applied to a route guidance method of a navigation device for the elderly according to an embodiment of the present invention. That is, a method of previously storing a destination input in step S11 of FIG. 1 is disclosed in FIG. 2.

Referring to FIG. 2, the storing of the destination in advance may include pre-determining and storing whether the right turn mode is always used for the pre-stored destination (S23). As described above, the right turn mode may be understood as a mode for performing the step S13 of determining the near destination of FIG. 1 and the step S14 of finding the right turn path.

As shown in Fig. 2, referring to the type of destination to be stored (S21), referring to a name for storing the destination (S22), selecting whether to always use the right turn mode (S23) or simply to save. It is made (S24).

Referring back to Figure 1 will be described the operation and effect of the present invention.

First, a destination may be input from the driver (S11), and the navigation may provide a screen for receiving whether to select a 'right turn mode'.

If the right turn mode is selected by the driver (S12), it is determined whether the destination or the current location is downtown, or whether the distance to the destination is a short distance destination of less than a preset reference distance (for example, 20 km). In the case of long distances that require long distances or secluded distances in the suburbs, it is preferable to select the right turn mode for the city center or short distance operation, because it may take too much time and distance to operate the right turn.

However, the driver may want to use the right turn mode even when driving long distances or suburbs, so that the driver may again check whether to use the right turn mode (S17), or receive a route of the right turn mode according to the result (S16), or other ordinary The route guidance of the mode may be received (S18).

If the condition determined in step S13 is satisfied, the right turn path is searched for (S14). In the step S14 of searching for the right turn route, it is preferable to avoid the road of the kind avoided by the old driver. For example, a one-lane road crossing without a center line or a path requiring unprotected left turn is preferably excluded from the searched right turn path.

The navigation may compare the estimated time taken to reach the destination by the right turn route determined in step S14 and the estimated time taken to arrive at the destination by the route found in a manner other than the right turn mode (S15). This step (S15) is a step prepared in consideration of the case where the destination arrival time by the right turn route is too long compared with the normal route. Even in this case, similarly to the step S13, the driver provides an opportunity to select whether to use the right turn mode (S17) and is guided the path of the right turn mode according to the user's selection (S16), or the path of another ordinary mode. You can receive the guidance (S18).

If the difference between the estimated time to reach the destination by the right turn route and the estimated time to reach the destination by the route found in a different way is less than the preset time (eg 15 minutes) The right turn route may be guided (S16).

According to the above-described method, when the destination arrives using the path in the right turn mode or the path in the other mode (S19), the operation of the navigation may be terminated.

On the other hand, one embodiment of the present invention may further include the step of storing the destination frequently in advance before the destination input step (S11) of FIG. This is explained in detail in FIG.

As shown in FIG. 2, when the destination dictionary input step is started, the type of destination to be stored is referred to (S21), the name of storing the destination is referred to (S22), or the right rotation mode is selected at all times (S23). ), It simply selects whether to save (S24). For example, when the destination type is a mart, a supermarket, or a school, a screen for selecting whether to use the right turn mode may be provided at step S23.

In step S23, when the right turn mode is selected by the user's selection, the contents are stored, and when the corresponding destination is read and the route is searched, the right turn mode is always searched.

As described above, the present invention can avoid the road or the route avoided by the older driver and reach the destination through the right turn as possible, thereby providing the elderly driver with the convenience of driving and the psychological stability.

In the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the following claims and their equivalents.
