Abstract

An autopilot system for a vehicle capable of steering the vehicle on a predetermined course by use of laser beams. The invention is comprised of: an off-board mounted laser transmitter, which describes the intended course of the vehicle, a vehicle mounted laser sensor array, a logic control unit, one or more actuators to control vehicle'"'"'s heading and a user interface.

Claims

1. An autopilot for a vehicle, where the vehicle includes steering means capable of being in a range of positions, the autopilot comprising:

A light source transmitter which emits light in a direction toward the vehicle, the light source transmitter located remote from the vehicle;

At least two detecting sensors capable of detecting the emitted light, each detecting sensor having a data output;

Data processing means for receiving data output from detecting sensors and calculating a desired vehicle course;

means for controlling the steering means of the vehicle, said steering control means being operably controlled by the data processing means; and

a user interface comprising signals for informing a user as to one or more of the following data;

vehicle speed, vehicle direction of travel, vehicle distance from a point remote from the vehicle, vehicle course information, vehicle load information, light source orientation, light source signal strength, and orientation of the vehicle'"'"'s steering means, the user interface capable of receiving data from the data processing means.

2. The autopilot of claim 1, further comprising:

A direction sensor for detecting the vehicle'"'"'s direction of travel, the direction sensor having a data output which interfaces with the data processing means.

3. The autopilot of claim 1, further comprising:

A speed sensor for detecting the vehicle'"'"'s travelling speed, the speed sensor having a data output which interfaces with the data processing means.

4. The autopilot of claim 1, further comprising:

A steering orientation sensor for detecting the orientation of the vehicle'"'"'s steering means, the steering orientation sensor having a data output which interfaces with the data processing means.

5. The autopilot of claim 1, where the user interface is located remote from the vehicle and the data processing means further comprises remote data transmission means for transmitting data to the remote user interface.

6. The autopilot of claim 1, where the data processing means controls a steering actuator based on a desired steering means position and an actual steering means position.

7. The autopilot of claim 1, where the light source transmitter is a laser.

8. The autopilot of claim 1, where the light source transmitter is a rotating beam laser transmitter.

9. The autopilot of claim 1, where the emitted light is in the form of a plane.

10. The autopilot of claim 1, further comprising at least one additional light source transmitter.

11. The autopilot of claim 1, further comprising means for controlling the speed of the vehicle.

12. An autopilot for a vehicle, where the vehicle includes steering means capable of being in a range of positions, the autopilot comprising:

A plurality of light source transmitters, where each light source transmitter emits light in a direction toward the vehicle and each light source transmitter is located remote from the vehicle;

At least two detecting sensors for detecting the emitted light, each detecting sensor having a data output;

Data processing means for receiving data output from detecting sensors and calculating a desired vehicle course;

means for controlling the steering means of the vehicle, said steering control means being operably controlled by the data processing means; and

a user interface comprising signals for informing a user as to one or more of the following data;

vehicle speed, vehicle direction of travel, vehicle distance from a point remote from the vehicle, vehicle course information, vehicle load information, light source orientation, light source signal strength, and orientation of the vehicle'"'"'s steering means, the user interface capable of receiving data from the data processing means.

13. The autopilot of claim 12, where the emitted light is in the form of a plane.

14. A method for controlling a vehicle remotely, the method comprising the steps of:

transmitting a light signal to the vehicle from a remote location;

detecting the light signal at the vehicle;

calculating the vehicle'"'"'s travel direction and speed relative to the detected light signal;

adjusting the direction of travel of the vehicle; and

providing information as to one or more of the following data;

vehicle speed, vehicle direction of travel, vehicle distance from a point remote from the vehicle, vehicle course information, vehicle load information, light source orientation, light source signal strength, and orientation of the vehicle'"'"'s steering means.
