Abstract

The invention discloses a vehicle navigation method which is as follows: according to the vehicle current position and a target position inputted by a user, calculating a first distance between the vehicle current position and the target position; according to the vehicle fuel tank current oil mass and vehicle unit mileage fuel consumption mass, calculating a second distance a vehicle can drive by relying on the current oil mass; judging whether the first distance is greater than the second distance; according to the judgment result, programming a path. The invention also discloses a vehicle navigation system. The vehicle navigation system can provide navigation for users in the condition of considering whether the vehicle current oil mass can reach target position inputted by the user, and the problem of vehicle breakdowns caused by lack of oil can be avoided.

Description

technical field [0001] The invention relates to the field of motor vehicles, in particular to a method and system for vehicle navigation. Background technique [0002] With the continuous development of the motor vehicle field, the vehicle navigation system has been increasingly used as a pre-installed component of the vehicle. Thereby bring great convenience to motor vehicle drivers, especially motor vehicle drivers who are not familiar with road conditions. [0003] In the prior art, the navigator performs path planning and navigation according to the destination set by the driver. However, the navigator only provides the guidance function or query function to the customer, without considering whether the existing oil quantity of the motor vehicle is enough to reach the destination, which may cause the vehicle to break down due to the exhaustion of fuel on the way. Contents of the invention [0004] The problem to be solved by the present invention is to provide a meth...
