Vehicle navigation device and economical road acquisition method using the same

Abstract

The invention relates to a vehicle positioning navigation technology in intelligent transportation, and especially relates to a vehicle navigation device and an economic road obtaining method. The vehicle navigation device comprises a microcontroller, a voice module, a power supply module, an LCD display, a GPRS communication module, a GPS module and an input interface, and the microcontroller is respectively connected with the voice module, the power supply module, the LCD display, the GPRS communication module, the GPS module and the input interface. The vehicle navigation device can guide a vehicle to run on a most economical road in order to realize the optimization and navigation of a vehicle driving path, and the respective height change and the road distance of obtained K shortest roads are calculated according to a relationship among the vehicle running fuel economy, the road distance and the road slope through the method in order to obtain the most economical vehicle running road.

Description

technical field [0001] The invention relates to a vehicle positioning and navigation technology in intelligent transportation, in particular to a navigation device and a method for acquiring economical roads for vehicles. Background technique [0002] In recent years, with the rapid development of the national economy, the number of domestic automobiles has increased year by year, and the continuous increase in traffic volume has brought great difficulties to the traffic management department. At the same time as the urban road construction, the continuous construction and extension of the road network has been well integrated with the urban traffic network. The road traffic network has formed a nationwide traffic network from a single piece, which makes the road traffic network increasingly complex. [0003] The development of the road network has to some extent replaced the problem of no way to go before the problem of how to go. The vehicle positioning and navigation sy...

Problems solved by technology

In addition, in the current situation of frequent traffic accidents, traffic safety has become a constant concern of drivers and traffic management departments

With the development of my country's economy, the number of cars has continued to increase, and the number of unskilled drivers has continued to increase. On roads with a lot of gradient changes, especially on roads with large gradient changes, unskilled drivers often cannot perform well. Traffic safety issues are particularly prominent when controlling vehicle movement
