First Claim
Patent Images
1. A navigation correction system comprising:
- a sensor for detecting operator input; and
a correction control unit coupled to said sensor for monitoring said sensor, said correction control unit operable, upon operator input indicating a correction to a travel path of a vehicle, to communicate with a guidance control system so as to correct said travel path of said vehicle without returning control of steering of said vehicle to an operator of said vehicle.

Abstract
A method and apparatus which allows for corrections to be made to the path of a vehicle when an automatic steering control feature of a guidance control system is in operation. A sensor is coupled to the steering system detects movement of the steering wheel by the operator. When the operator moves the steering wheel the logic of the correction controller adjusts the travel path of the vehicle to correspond to the movement of the steering wheel. In one embodiment the travel path is adjusted by instructions transmitted to the controller of the guidance control system. Correction of the travel path may also be obtained by the operation of a keypad or a joystick.

6. A method for correcting the travel path of a vehicle comprising:
-
a) monitoring a sensor that detects operator input; and
b) upon receiving operator input that indicates that a correction is to be made to a travel path of a vehicle, communicating with a guidance control system so as to correct said travel path of said vehicle without returning control of steering of said vehicle to an operator of said vehicle. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
c) monitoring a button, said travel path of said vehicle corrected when said button is pressed and when said sensor detects said movement of said steering wheel.

-
12. The method of claim 6 wherein said sensor detects direction of movement of a steering wheel and wherein said direction of movement of said steering wheel determines the direction in which said correction to said travel path is applied.
-
13. The method of claim 6 wherein said sensor comprises a joystick.

14. In a computer system including a processor coupled to a bus, and a memory unit coupled to said bus for storing information, a computer-implemented method for correcting the travel path of a vehicle comprising the steps of:
-
a) monitoring a sensor that detects operator input; and
b) upon receiving operator input that indicates that a correction is to be made to a travel path of a vehicle, communicating with a guidance control system so as to correct said travel path of said vehicle without returning control of steering of said vehicle to an operator of said vehicle. - View Dependent Claims (15, 16, 17, 18, 19, 20)
c) monitoring a button, said travel path of said vehicle corrected when said button is pressed and when said sensor detects said movement of said steering wheel.
