NAVIGATION FUNCTION [TYPE A]

id092000101330

Outline

• A vehicle's position is measured by a hybrid method of autonomous navigation (using yaw-rate signals from the gyro sensor and vehicle speed signals from the DSC HU/CM) and GPS navigation (using signals from GPS satellites). Accurate detection of the vehicle's position is possible based on the adoption of a map-matching function which specifies the vehicle's position as compared with the map data read from the DVD-ROM and the vehicle's position measured from autonomous navigation and GPS navigation.
• Guidance to destination is provided via display of the recommended route on the map screen, as well as voice messaging guidance at intersections and points of divergence.
• Based on inputted signals and information on the DVD-ROM, the following features are available:
- Destination can be selected based on address, intersection, POI (Point of Interest), history, memory or map.
- Route information is available in map and guide mode.
- Voice guidance and menus are available in six languages.
- A map screen that displays maps in twelve steps with scales from 100 m to 500 km.
- A map screen that displays routes according to Shortest Route and Avoid Motorway functions.
- A detour function which provides three routes to select from based on streets selected to avoid, up to five via points and calculation of set detour distance.
- A wide variety of preferential settings are available.
