  • Systems and methods for classifying and responding to heading error in marine propulsion
    Patent number: 12473067
    Abstract: A method of operating a marine drive configured to propel a marine vessel is provided. The method includes operating the marine drive to effectuate a specified heading, measuring a heading of the marine vessel using a heading sensor, and measuring acceleration data of the marine vessel using at least one sensor. The method further includes determining that a heading error between the specified heading and the measured heading exceeds a heading error threshold, classifying the heading error based at least in part on the measured acceleration data during a time period prior to the heading error, and performing a heading error response based on the heading error classification.
