Patent number: 10222801Abstract: A movement route generating apparatus includes an angle calculating unit calculating an angle formed by a vehicle travel direction at a target position compared with that at the current position, a graph generating unit generating a graph that has most gentle inclinations by plotting the curvature of a travel trajectory matching the steering angle of the vehicle and a distance traveled on two axes, under the condition that the area of a graph generated in correspondence to a travel trajectory from the current position to the target position is equal to the angle and other conditions, and a route setting unit setting a travel trajectory represented by the graph as the movement route of the vehicle. Accordingly, a travel trajectory with the smallest degree of change in curvature per unit distance traveled, that is, a low horizontal angular velocity caused by vehicle steering, can be set as a movement route.Type: GrantFiled: June 9, 2017Date of Patent: March 5, 2019Assignee: Alpine Electronics, Inc.Inventors: Hiroki Oba, Kosuke Munakata, Tetsuro Yabe
