Apparatus and method of generating travel route of vehicle

Abstract

Provided are an apparatus and a method of generating a travel route, which generate a travel route by using fixed objects positioned at a front side. The apparatus for generating a travel route includes: a space information obtaining unit configured to obtain information on a space, in which a driver's vehicle is allowed to travel, by using fixed objects positioned at both sides of the driver's vehicle; a travelling direction estimating unit configured to estimate a travelling direction of the driver's vehicle based on travelling information about the driver's vehicle and information on distances to the fixed objects; and a travel route generating unit configured to generate a travel route of the driver's vehicle based on the space information and the travelling direction of the driver's vehicle.

Description

technical field [0001] The present invention relates to a device and method for generating a driving route of a vehicle, and more specifically to a device and a method for generating a driving route of a vehicle without using GPS. Background technique [0002] In conventional unmanned vehicles, after setting a travel route in advance, the travel of the vehicle is controlled based on the current position of the vehicle obtained from GPS. This conventional travel control method has the following problems. [0003] First, since the GPS and the specified map are the center, the vehicle can only travel along the route specified by the position sensor inside the vehicle, so when changing obstacles or road information, there is a problem that the vehicle cannot drive to a space that can be avoided. That is, in the case of changing objects or maps within the travel route, the vehicle cannot initiate avoidance using external sensors. [0004] Second, when the designated travel route...

AI Technical Summary

Problems solved by technology

[0003] First, with the GPS and the specified map as the center, the vehicle can only travel on the route specified by the position sensor inside the vehicle, so when changing obstacles or road information, there is a problem that the vehicle cannot drive to a space that can be avoided

That is, in the case of changing objects or maps within the driving path, the vehicle cannot use external sensors to initiate avoidance

[0004] Second, when the designated travel route changes due to vehicle speed variability, the problem of deviating from the travel route occurs due to failure to consider the dynamic behavior of the vehicle

[0005] Korean Laid-Open Patent No. 2011-0041841 describes a system for finding driving routes of electric vehicles, but the system also uses GPS to generate driving routes, so it cannot solve the above-mentioned problems
