Remote control system and method for an autonomous vehicle
First Claim
1. A method for remotely controlling an autonomous vehicle, comprising:
- establishing radio communications with the vehicle via a tele-panel, wherein a vehicle identifier and a tele-panel identifier are transmitted to the vehicle, and wherein establishing radio communications ceases autonomous operation of the vehicle and places the vehicle in a tele-ready mode in which the vehicle will not respond to commands from other tele-panels;
communicating a tele-operation request signal to the vehicle, said tele-operation request signal placing the vehicle in a tele-operation mode in which the vehicle is responsive to speed and steering angle requests from the tele-panel;
if communications between the vehicle and said tele-panel identified by said tele-panel identifier are interrupted while the vehicle is in said tele-operation mode, halting operation of the vehicle, preventing autonomous operation of the vehicle, and preventing control of the vehicle by any other tele-panel; and
if communications between the vehicle and said tele-panel identified by said tele-panel identifier are interrupted while the vehicle is in said tele-ready mode, allowing autonomous operation of the vehicle and allowing control of the vehicle by another tele-panel.

Abstract
A system and method for remotely controlling an autonomous vehicle uses a tele-panel to interrupt autonomous operation. Radio communications established between the tele-panel and the vehicle ceases autonomous operation of the vehicle and places the vehicle in a tele-ready mode in which the vehicle will not respond to commands from other tele-panels. Upon communication of a tele-operation request signal to the vehicle, the vehicle enters tele-operation mode. In this mode, the vehicle is responsive only to speed and steering angle requests from the transmitting tele-panel. A unique tele-panel identifier transmitted to the vehicle prevents other tele-panels from gaining control of the vehicle. If communications between the vehicle and the tele-panel identified by the tele-panel identifier are interrupted while the vehicle is in tele-operation mode, the vehicle is locked and will not respond to commands from other tele-panels and will not enter autonomous operation. If communications between the vehicle and the tele-panel identified by the tele-panel identifier are interrupted while the vehicle is in the tele-ready mode, autonomous operation or control by other tele-panels is not prevented.

7. A system for remotely controlling an autonomous vehicle, comprising;
-
a tele-panel having control means for allowing an operator to generate speed and steering angle commands, mode select means for allowing an operator to select an operational mode of said vehicle, processor means for receiving said speed and steering angle commands from said control means and said selected operational mode from said select means, for generating a vehicle identifier and a tele-panel identifier, and for formatting said vehicle identifier, said tele-panel identifier, said selected operational mode, and said speed and steering angle command into a data packet, and transmitter means for establishing communications with the vehicle and for transmitting said data packet to the vehicle, and vehicle control means, mounted on said vehicle, for receiving said communications from said tele-panel and for controlling operation of the vehicle in response thereto, said vehicle control means having receiver means for receiving said communications from said transmitter means, mode set means for placing the vehicle in a tele-ready mode in response to said data packet received from said tele-panel and for placing the vehicle in tele-operation mode when said selected operational mode of said data packet indicates tele-operation mode, means for producing vehicle speed and steering angle control signals in response to speed and steering angle commands in said data packet, and means for halting operation of the vehicle, preventing autonomous operation of the vehicle, and preventing control of the vehicle by another tele-panel if communications between the vehicle and said tele-panel identified by said tele-panel identifier are interrupted while the vehicle is in said tele-operation mode. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
