What is the Front Vehicle Voice Alert Function?
1 Answers
Front vehicle voice alert is a voice prompt function. Below is more information about in-car navigation: 1. In-car navigation: In-car navigation uses the vehicle's GPS (Global Positioning System) in conjunction with electronic maps to conveniently and accurately inform the driver of the shortest or fastest route to the destination, serving as a good assistant to the driver. 2. Signal reception: The GPS system works by analyzing signals received from synchronous satellites. These signals can be visually represented as inverted funnel shapes when projected onto a vertical plane. When the lower parts of these 'funnels' overlap to a certain extent, the GPS analysis program can calculate the coordinates of the car's current location. 3. Signal processing: The signals received by the GPS and the information provided by the speed measurement device are transmitted to the car navigation system through the receiver, where they are analyzed and processed by the software system and overlaid on the stored map. 4. Voice navigation: It provides driving information such as upcoming turns and navigation system status to the driver in advance through voice, much like a knowledgeable guide telling the driver how to reach the destination. This is one of the most important functions of navigation, allowing the driver to reach the destination safely without needing to look at the operation terminal, relying solely on voice prompts. 5. Visual navigation: The operation terminal displays the map, the car's current location, driving speed, distance to the destination, planned route prompts, and turning information at intersections. 6. Route planning: If the driver does not follow the planned route or takes a wrong turn, the GPS navigation system will recalculate a new route to the destination based on the current location.
