and S202, displaying the navigation path of the new destination on the navigation map.
More specifically, in a conventional intersection query, only one coordinate point is provided, and one point at the intersection of two roads is used as the destination point. In fact, most users query the intersection of the a-way and the B-way, with the ultimate goal being some point on the a-way or on the B-way near the intersection. According to the proposal, after a user searches for a certain intersection, a thumbnail of the intersection is popped up, and the user selects a final destination on the thumbnail, namely on the A road or the B road. In the traditional method, the intersection point of the path A and the path B is directly taken, most of the situations are not the final purpose that a user really wants to go, and the route calculated by taking the intersection point has access to the expected destination of the user, so that the user experience is influenced. In the using process of a user, 1, searching for 'A path and B path' to obtain the coordinates of the intersection of the A path and the B path. 2. Road data of the A-way and the B-way near the coordinate point are acquired from the map data. 3. And popping up road intersection magnifications of the road A and the road B (a red dot is a default intersection coordinate point). 4. The user clicks on the desired point and sets a new destination (green is the point the user has newly clicked on). 5. And setting the point newly clicked by the user as a destination. Instead of using the default intersection of the two roads, the user can select a point near the a road, or a point near the B road. And the destination can be selected to be on the left or right of the road, so that the destination is more in line with the requirements of the user, and the user experience is optimized.

Over 20 years of practice, the GPS system has proven to be a high-precision, all-weather, and global multifunctional system for radio navigation, positioning, and timing. The GPS technology has been developed into a multi-field, multi-mode, multi-purpose, multi-model international high and new technology industry. The recent development trend of car navigation systems is to receive signals transmitted from a car GPS by using Bluetooth (Bluetooth) wireless technology. Thus, the on-board system only needs to receive and process satellite signals, and the display device is responsible for map storage and position overlapping. Therefore, if you already have a palmtop, you only need to buy one signal receiver and mapping software; your palm computer accomplishes one machine multipurpose. In fact, many mobile phones already have the function of a GPS, and if the mobile phone is added with the function of overlapping maps, the mobile phone can become a set of mobile navigation systems. In addition to being used to navigate your way, car navigation systems may be used to develop many other uses, such as helping you find nearby gas stations, cash dispensers, hotels, or some other store. Some can also tell you how to avoid dangerous areas or traffic jams. Most vehicle navigation systems utilize a visual display system as an interface for human-machine communication. Some provide voice systems to allow people to talk directly to the navigation system and to use voice to remind motorists when they should turn and when they should exit the highway. Some may provide a map of the route with you for return or may return if you are walking wrong. Some car navigation systems can also have different language displays. Some can also tell you the local speed limit, road conditions and your average speed, estimate the time to reach the destination for you. The product core function is 1) map query, and the destination position where you want to go can be searched on the operation terminal. The position information of places where you often go can be recorded and reserved, and the position information can be shared with other people. The method comprises the following steps of (1) fuzzy inquiry of information such as a gas station, a hotel, a cash dispenser and the like near your accessories or a certain position, and 2) route planning, wherein a GPS navigation system can automatically plan a route according to a starting point and a destination set by your. The planned route may set whether certain waypoints are to be passed. The planned route can be set to avoid the high speed function. 3) Automatic navigation, voice navigation: the voice is used for providing driving information such as intersection steering and navigation system conditions for a driver, and the method is similar to a guide for telling the driver how to drive to a destination. The most important function in navigation enables a user to safely reach a destination through voice prompt without watching an operation terminal. And (3) picture navigation: on the operation terminal, a map, the position of the vehicle, the driving speed, the distance of the destination, the planned route prompt and the driving information of the intersection steering prompt are displayed. And (3) re-planning the line: when you are not driving according to the planned route or go wrong, the GPS navigation system replans a new route to the destination according to the current position of you.
