RTK GPS VEHICLE LEANING MEASURING METHOD USING HIGHLY ACCURATE LOCATION INFORMATION BASED ON RTK GPS

摘要

The present invention relates to a vehicle deviating method using high-precision position information based on an RTK GPS technology, and more particularly, to a vehicle steer measuring method using RTK GPS technology, in which a vehicle traveling on a straight line section of a predetermined distance at a predetermined speed, A method of measuring a vehicle leaning using high-precision position information based on RTK GPS technology of the vehicle, the method comprising the steps of: (1) using the position information of the RTK GPS terminal at a start point of the straight line section, Calculating an entry angle, (2) measuring the final position of the vehicle using the position information of the RTK GPS terminal when the vehicle is traveling in the straight line section; (3) calculating an expected position of the vehicle in which the vehicle can arrive by linearly traveling the straight line section at the predetermined speed at the start point of the straight line section in accordance with the approach angle calculated in the step (1) ; And (4) determining the leaning of the vehicle using the expected position of the vehicle calculated in the step (3) and the final position of the vehicle measured in the step (2). . According to the vehicle devoting method using the high-precision position information based on the RTK GPS technology proposed in the present invention, by using the position information of the vehicle collected every predetermined period from the RTK GPS terminal installed in the vehicle, And the degree of the deviation is quantified, so that the deviation of the vehicle can be objectively judged. Further, according to the present invention, by calculating the approach angle at which the vehicle enters at the starting point of the straight line section and calculating the predicted position of the vehicle with respect to the approach angle, it is possible to accurately estimate the actual vehicle's steepness even when the vehicle does not correctly enter the straight line section Can be measured.
