DENSO’s Current Hybrid System
DENSO’s present car navigation uses a hybrid system that combines the independent navigation and the GPS navigation systems. With this hybrid system, navigation is possible even in areas that are out of reach of the GPS signal such as:
- Within a tunnel
- In a street lined with tall buildings
- Under an elevated freeway
- In a dense forest
| Outline | Description |
| Calculation of vehicle position |
Calculates the vehicle position |
| Processing of the vehicle position data on the map | Displays the current location and the track of the vehicle on the map |
| Map Matching | Compares the data of the current location and the track of the vehicle against the map data and aligns the vehicle position with the nearest road. |
| GPS correction | Aligns the vehicle position to the position plotted by the GPS. |
| Distance correction | Reduces (or corrects) the difference between the driving distance signals and distance data on the map |
Construction of Car Navigation
The car navigation system consists of a Nav ECU, display, GPS antenna, and a remote controller.
