Method for controlling manual driving mode of autonomous vehicle
First Claim
1. A method for controlling a manual driving mode of an autonomous vehicle, the method comprising:
- a manual mode detecting step wherein a controller is configured to detect whether the vehicle is switched from an autonomous driving mode to the manual driving mode;
a first control step wherein the controller is configured to control an angle of a tire and a steering angle of a steering wheel based on travel route information when switching to the manual driving mode is detected as a result of the manual mode detecting step;
a delay time determination step wherein the controller is configured to determine a delay time of a change of the angle of the tire with respect to a change of the steering angle of the steering wheel by comparing the change in the angle of the tire with the change in the steering angle of the steering wheel for a predetermined time period after the first control step;
a delay time comparison step wherein the controller is configured to compare the determined delay time with a predetermined time period after the delay time determination step;
a second control step wherein the controller is configured to control only the steering angle of the steering wheel based on the travel route information when the delay time is within the predetermined time period as a result of the delay time comparison step; and
a third control step wherein the controller is configured to control the angle of the tire based on the steering angle of the steering wheel controlled through the second control step.

Abstract
A method for controlling a manual driving mode includes manual mode detecting step detecting whether a vehicle switched from autonomous to manual mode; first step controlling angle of tire and steering angle of a steering wheel using travel route information when switching to manual mode is detected; delay time determination step determining a delay time of change of the angle of the tire with change of the steering angle of the steering wheel by the change in the angle of the tire with the change in the steering angle of the steering wheel for predetermined time; delay time comparison step comparing the determined delay time with predetermined time period; second step controlling only the steering angle of the steering wheel using travel route information when delay time is within the predetermined time period; and third step controlling angle of the tire by steering angle of the steering wheel.
