Problems solved by technology

At present, the judgment of the straight-line driving direction of the vehicle is usually linear fitting after collecting enough points, but most of the points collected by this method are relatively scattered, and the linear correlation is low, so it cannot accurately judge the vehicle The straight direction of travel, resulting in a large error

Abstract

An embodiment of the invention discloses a method for generating vehicle straight driving direction indications. The method comprises: determining whether a driving state of a vehicle is a straight driving state; when the driving state of the vehicle is the straight driving state, obtaining a plurality of three-dimensional coordinates output by a three-axis acceleration sensor of the vehicle in preset duration and caching; according to the plurality of three-dimensional coordinates output by the three-axis acceleration sensor, generating a straight line indicating a vehicle straight driving direction. An embodiment of the invention also discloses a device for generating vehicle straight driving direction indications. The method and the device make linear dependency of acquired points high, so as to accurately determine the straight direction of vehicle driving, and reduce errors.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for generating and indicating the straight-line driving direction of a vehicle. Background technique [0002] With the development of society and the continuous improvement of people's living standards, the number of cars has increased significantly, and the safety of vehicles has also attracted more and more attention. [0003] Among them, the attitude of the vehicle, such as rapid acceleration, rapid deceleration, sharp turn, and straight-line driving, is an important parameter of vehicle operation and plays an extremely important role in the safety control of the vehicle. At present, the judgment of the straight-line driving direction of the vehicle is usually linear fitting after collecting enough points, but most of the points collected by this method are relatively scattered, and the linear correlation is low, so it cannot accurately judge...
