## Abstract

An arrival detection method for automatically detecting arrival of a current destination based on various conditions and proceeding to route guidance for the next destination when two or more destinations are specified. The method includes the steps of guiding a vehicle of the user to a current destination through a route guidance operation of the navigation system, detecting whether a current vehicle position is within a predetermined distance from the current destination, applying a primary condition when the vehicle is within the predetermined distance, applying a secondary condition when the primary condition is met, and determining arrival at the current destination when the secondary condition is met and proceeding to a route guidance operation for the next destination.

## Claims

### Claim 1

A navigation method for guiding a user to a destination based on a map data where two or more destinations are set in a navigation system, comprising the following steps of:
guiding a vehicle of the user to a current destination through a guided route by a route guidance operation of the navigation system;
detecting whether a current vehicle position is within a predetermined distance from the current destination;
applying a primary condition when the vehicle is within said predetermined distance;
applying a secondary condition when the primary condition is met; and
determining arrival at the current destination when the secondary condition is met and proceeding to a route guidance operation for the next destination.

### Claim 2 (depends on 1)

A navigation method as defined in claim 1, wherein the primary condition is a time length during which the vehicle is stationary within the predetermined distance from the current destination.

### Claim 3 (depends on 1)

A navigation method as defined in claim 1, wherein the secondary condition is whether the vehicle is on or away from a street segment of the map data defined by an address of the current destination when the primary condition is satisfied.

### Claim 4 (depends on 1)

A navigation method as defined in claim 1, wherein the secondary condition is whether a turn signal of the vehicle is activated or not.

### Claim 5 (depends on 1)

A navigation method as defined in claim 1, wherein the secondary condition is whether a parking brake of the vehicle is used after the primary condition is satisfied.

### Claim 6 (depends on 1)

A navigation method as defined in claim 1, wherein the secondary condition is whether the vehicle is turned before or after the primary condition is satisfied.

### Claim 7 (depends on 1)

A navigation method as defined in claim 1, wherein the secondary condition is to consider a type of current destination and when the type of destination so requires, the arrival of the current destination is determined even if the primary condition is not met.

### Claim 8 (depends on 1)

A navigation method as defined in claim 1, wherein the secondary condition is whether the vehicle moves in the backward direction.

### Claim 9 (depends on 1)

A navigation method as defined in claim 1, wherein the secondary condition is a degree of distance between the vehicle and a street segment of the map data defined by the address of the current destination.

### Claim 10 (depends on 2)

A navigation method as defined in claim 2, wherein the time length during which the vehicle is stationary is ten seconds.

### Claim 11

A navigation method for guiding a user to a destination based on a map data where two or more destinations are set in a navigation system, comprising the following steps of:
guiding a vehicle of the user to a current destination through a guided route by a route guidance operation of the navigation system;
detecting whether a current vehicle position is within a predetermined distance from the current destination;
applying at least two conditions when the vehicle is within said predetermined distance; and
determining arrival at the current destination when the two conditions are met and proceeding to a route guidance operation for the next destination.

### Claim 12 (depends on 11)

A navigation method as defined in claim 11, wherein one of conditions is a time length during which the vehicle is stationary within the predetermined distance from the current destination.

### Claim 13 (depends on 11)

A navigation method as defined in claim 11, wherein one of the conditions is whether the vehicle is on or away from a street segment of the map data defined by an address of the current destination.

### Claim 14 (depends on 11)

A navigation method as defined in claim 11, wherein one of the conditions is whether a turn signal of the vehicle is activated or not.

### Claim 15 (depends on 11)

A navigation method as defined in claim 11, wherein one of the conditions is whether a parking brake of the vehicle is used.

### Claim 16 (depends on 11)

A navigation method as defined in claim 11, wherein one of the conditions is whether the vehicle is turned before or after the other condition is satisfied.

### Claim 17 (depends on 11)

A navigation method as defined in claim 11, wherein one of the conditions is to consider a type of current destination and when the type of destination so requires, the arrival of the current destination is determined even if part of the set of condition is not met.

### Claim 18 (depends on 11)

A navigation method as defined in claim 11, wherein one of the conditions is whether the vehicle moves in the backward direction.

### Claim 19 (depends on 11)

A navigation method as defined in claim 11, wherein one of the conditions is a degree of distance between the vehicle and a street segment of the map data defined by the address of the current destination.

### Claim 20

A navigation method for guiding a user to a destination based on a map data where two or more destinations are set in a navigation system, comprising the following steps of:
guiding a vehicle of the user to a current destination through a guided route by a route guidance operation of the navigation system;
detecting whether a current vehicle position is within a predetermined distance from the current destination;
detecting whether the vehicle is stationary or in motion within said predetermined distance;
detecting whether an engine of the vehicle is shut down after the vehicle is in stationary;
determining arrival at the current destination when detecting the engine shut down; and
proceeding to a route guidance operation for the next destination.
