Abstract
A system and method for utilizing multiple driver stations in a track vehicle is described. A primary driver station can utilize controls with hybrid drive by wire (DbW) functionality (i.e. hydro-mechanical and electric control). A secondary driver station and a tertiary driver station can utilize controls with DbW (i.e. electronic) control systems. The secondary and tertiary driver stations can be adapted for autonomous driving. The invention also includes a method of transfer between driver stations with safeguards for safety and reliability.
Claims28
A system for transferring driving control of a moving vehicle from a first driver station to a second driver station, said system comprising:
- a platform manager to confirm that parking brake settings are the same at the first driver station and the second driver station;
- and
- a transmission control module for checking shutdown faults;
- wherein said transmission control module provides requirements to complete the transfer, and
- wherein said transmission control module disables the first driver station and enables the second driver station after the requirements are satisfied, and
- wherein each of the first driver station and second driver station comprise manual controls for steering, braking, gear selection and acceleration,
- wherein upon the transfer of driving control the first driver station's controls for steering, acceleration and gear selection are disabled and the control for braking remain functional.
A method of transferring control of a moving vehicle from a first driver station to a second driver station during mobile operation of the vehicle, the method comprising the steps:
- initiating a request for transfer;
- confirming that a parking brake setting at the first driver station matches a parking brake setting at the second driver station;
- and
- upon satisfying requirements for transfer, disabling the first driver station and enabling the second driver station,
- wherein each of the first driver station and second driver station comprise manual controls for steering, braking, gear selection and acceleration,
- wherein upon the transfer of driving control the first driver station's controls for steering, acceleration and gear selection are disabled and the control for braking remain functional.
