| An autopilot for a vessel for use in combination with a depth finder having a transducer, including a means for setting and storing a desired characteristic to be followed by the vessel, means for measuring the characteristic to be followed by the vessel, and means for storing a signal generated by the measuring means indicative of the measured characteristic. Once received and stored, the measured characteristic is compared to the selected characteristic. Based upon the comparison between the two characteristics, at least one servo motor is actuated to alter the direction the vessel is traveling. A servo motor may be coupled to the helm or to an outboard motor mounted to the vessel. The speed of the vessel may also be controlled based upon a comparison between a measured value and a selected value. | ||||||

| An autopilot system for a vessel such as a boat receives a pre-set heading direction set by e.g. the user and also receives the apparent orientation (heading) from a heading sensor. The difference between the pre-set heading direction and the actual heading is then determined and a correction signal is generated in dependence on that difference, which correction signal is then used to control the orientation of the vessel by e.g. generating a rudder correction signal which varies the position of the rudder. In the present invention, the correction signal is further dependent on the difference between the actual heading and a reference direction such as magnetic North or South. In this way errors due to differences between the apparent orientation as detected by the heading sensor and the actual orientation of the vessel may be corrected. The correction value may alternatively, or in addition, be dependent on magnetic dip angle, and/or the vertical and/or horizontal component of the Earth's magnetic field, and/or latitude. | ||||||

| An autopilot system for a vessel such as a boat has an autopilot unit connected via a drive to the rudder or other direction determining means of the vessel. When the autopilot unit is operating normally, direction information from e.g. a heading sensor is processed by the autopilot unit and the drive is controlled by the autopilot unit to determine the appropriate position of the rudder. The rudder is also linked to a steering wheel or other manual steering arrangement. When the steering wheel is moved during normal operation of the autopilot unit, this causes an interference with the control of the rudder by the drive and, if this interference has sufficient magnitude and duration, this triggers override of the autopilot unit, returning the vessel to manual control via the steering wheel. The override may alternatively be triggered by detection of rudder movement by a sensor. | ||||||

| Apparatus for steering a vessel and maintaining it on a preset course through the combination and arrangement of an incremental encoder and a heading reference circuit is disclosed. The encoder includes circuitry operative to generate a directional signal and count pulse for each incremental movement of the vessel away from the preset heading and for transmitting same into a heading reference circuit. Counting means are included in the heading reference circuit including adjustable reference setting means to set the counter at a reference position corresponding to the preset heading. The counter is responsive to the pulses received from the incremental encoder to count in a positive or negative direction under the control of the directional signals. A sign-detector in the counter detects whether the total number of pulses is positive or negative with respect to the reference position and generates a signal representative of the direction of the net change. | ||||||

| A learning autopilot for a vehicle provides the capability to command complex maneuvers or maneuver the vehicle when control by its ground station is not possible. A memory is used during a piloted rehearsal mission and position and time information for the aircraft is stored in the memory. This memory is incorporated into the vehicle control system, and during automatic operation of the aircraft, the recorded position and relative time information is retrieved and compared against position and relative time information occurring during automatic flight. The difference between the recorded information and the actual flight information is used to generate error signals which are converted to command signals for the vehicle. Maneuvers which were initiated and completed by the pilot during the rehearsal mission are then repeated during the automatic flight from the flight information stored in the memory. | ||||||

| A marine autopilot apparatus having a microcomputer for controlling a rudder control loop formed of at least a rudder servo amplifier, and a power unit, for detecting an abnormality concerning the steering of a rudder and for indicating an alarm concerning the detected abnormality and the like. A representing alarm indicator lamp classifying the abnormalities into a single or plurality of groups and for collectively indicating the abnormalities in the form of the single or plurality of groups. A general-purpose indicator for indicating various data at least concerning the steering, set values and respective contents of the abnormalities detected and a rudder control collective alarm circuit for indicating the occurrence of the abnormality in the rudder control loop. The rudder control collective alarm circuit is driven when at least one of a plurality of alarm points within the rudder control loop, and the power unit exhibits an abnormal condition. | ||||||

| An autopilot system for use primarily in conjunction with marine craft. The system comprises heading error, heading rate, and feedback circuitry for producing signals which are algebraically summed and fed to two separate comparators. The comparators produce ''''steer left'''' and ''''steer right'''' output command signals when the output signal from the summing amplifier bears a predetermined relationship to a set of reference signals. The signals from the heading error, heading rate, and feedback circuits are scaled so that the heading rate circuit has the capability of overriding the other two circuit signals and causing saturation of the output of the summing amplifier resulting in continuous operation of the rudder motor when the rate of change in craft heading exceeds a given value. Apparatus is also provided for varying this given value. The feedback circuit is connected to both comparator outputs and comprises an integrator circuit which imposes pulse width modulation into the operation of the rudder motor in accordance with the direction and duration of previous rudder motor actuations.
