Problems solved by technology

However, a typical vehicle only has dedicated sensors to monitor and assist the performance of the vehicle, not measurement sensors capable of mapping
Equipping these vehicles with the necessary additional measurement sensors and cameras to collect map information is expensive
In addition, driving special vehicles around the vast road network to collect map information is time-consuming and laborious

Embodiment Construction

[0066] In the following description, the same reference numerals will be used throughout to identify the same parts.

[0067] Embodiments of the invention will now be described with specific reference to PNDs. However, it should be kept in mind that the teachings of the present invention are not limited to PNDs, but are generally applicable to any type of processing device configured to execute navigation software in a manner configured for in-vehicle use in order to provide route planning and navigation functionality. Thus, it can be seen that in the context of this application, a navigation device is intended to include, without limitation, any type of route planning and navigation device, whether embodied as a PND, a vehicle such as an automobile, or an actual Embodied on a portable computing resource (eg, a portable personal computer (PC), mobile phone, or personal digital assistant (PDA)) executing route planning and navigation software.

[0068] As will also be apparen...

Abstract

A navigation apparatus (200) comprises a processing resource (202) that is operably coupled to a data store (214) comprising digital map data. A location determination unit (288) is also provided and capable of determining a location. The navigation apparatus receives information from at least a vehicle: steering sensor for sensing an angular position of the vehicle steering control. Information relating to the sensed parameters is logged by the navigation apparatus while driving. Upon subsequent uploading of the information to a server (150), the information is analysed statistically, and combined with similar information obtained from other navigation devices. The statistical analysis enables supplementary road information to be derived, such as road lane width; Such supplementary road information is added to the digital map to facilitate greater safety awareness and route planning.

Description

technical field [0001] The invention relates to the field of navigation devices for use in vehicles and methods associated with said navigation devices. The device may, for example, be mounted as integral vehicle equipment, or may be a portable device configured or configurable for use within a vehicle. Background technique [0002] Portable computing devices, such as portable navigation devices (PNDs), that include GPS (Global Positioning System) signal reception and processing functionality are well known and widely used as in-car or other vehicle navigation systems. [0003] In general, modern PNDs include a processor, memory (at least one of volatile memory and non-volatile memory, and often both), and map data stored within the memory. The processor cooperates with the memory to provide an execution environment in which a software operating system can be established and, in addition, often one or more additional software programs are provided to enable control of the f...
