Systems and methods for providing redundant pulse-width modulation (PWM) throttle control

A method for providing redundant pulse-width modulation (PWM) throttle control, comprising:

• generating at least one PWM throttle control signal;
• and
• outputting one of the at least one PWM throttle control signals to an engine, using an automated throttle control system, wherein the automated throttle control system comprises:
• a plurality of automated throttle controllers, each of the plurality of automated throttle controllers being configured to independently control a throttle of a vehicle, and each comprising:
• a processor configured to generate and output an automated PWM throttle control signal;
• a first relay that, when engaged, is configured to receive and output a manual PWM throttle control signal from a manual throttle controller;
• and
• a second relay, configured to:
• receive and output the automated PWM throttle control signal to the engine, when the second relay is engaged;
• and
• receive and output the manual PWM throttle control signal to the engine, when the second relay is disengaged,
• wherein:
• the plurality of automated throttle controllers includes at least a primary throttle controller and a backup throttle controller, and
• at any given time, the automated throttle control system is configured to output, to the engine, one of the following:
• the manual PWM throttle control signal;
• the automated PWM throttle control signal generated by the primary throttle controller;
• and
• the automated PWM throttle control signal generated by the backup throttle controller.
