  • Patent number: 9103287
    Abstract: Drive-by-wire control systems and methods for a marine engine utilize an input device that is manually positionable to provide operator inputs to an engine control unit (ECU) located with the marine engine. The ECU has a main processor that receives the inputs and controls speed of the marine engine based upon the inputs and a watchdog processor that receives the inputs and monitors operations of the main processor based upon the inputs. The operations of the main processor are communicated to the watchdog processor via a communication link. The main processor causes the watchdog processor to sample the inputs from the input device at the same time as the main processor via a sampling link that is separate and distinct from the communication link. The main processor periodically compares samples of the inputs that are simultaneously taken by the main processor and watchdog processor and limits the speed of the engine when the samples differ from each other by more than a predetermined amount.

    Abstract: By obtaining an atmospheric pressure learning value by applying filtering to an estimated atmospheric pressure found from an estimated atmospheric pressure map in an atmospheric pressure learning region matched in advance, and by constantly updating this atmospheric pressure learning value, stable and highly reliable atmospheric pressure estimation can be achieved. Also, a pre-set parameter value or the last atmospheric pressure learning value is used as the initial atmospheric pressure value and an unstable intake pressure value at the engine start in a battery-less state is not used. Hence, it becomes possible to provide an estimated atmospheric pressure with which high drivability is achievable by fully exploiting the engine performance as soon as the engine is started.

  • Patent number: 8961246
    Abstract: Systems and methods are for controlling shift in a marine propulsion device. A shift sensor outputs a position signal representing a current position of a shift linkage. A control circuit is programmed to identify an impending shift change when the position signal reaches a first threshold and an actual shift change when the position signal reaches a second threshold. The control circuit is programmed to enact a shift interrupt control strategy that facilitates the actual shift change when the position signal reaches the first threshold, and to actively modify the first threshold as a change in operation of the marine propulsion device occurs.

  • Patent number: 8966654
    Abstract: A novel privacy control-adjustable vehicle monitoring system and a related method of operation provide a dynamically-adjustable access grant or denial of privacy-sensitive vehicle information to a vehicle monitoring personnel based on a driver's response to an electronic request made by the vehicle monitoring personnel. In one embodiment, vehicle information is categorized into a mandatory disclosure dataset and a privacy-adjustable dataset, wherein the mandatory disclosure dataset is disclosed to the vehicle monitoring personnel at all times, while the privacy-adjustable dataset is accessible if the driver grants access via a driver's user interface on an onboard vehicle user interface, or on a mobile electronic device. Furthermore, a special wild card mode visible to the driver enables the vehicle monitoring personnel to access an entire set of vehicle information for a limited period per access and for a limited number of accesses per period, based on a pre-arranged consent with the driver.

  • Patent number: 8965674
    Abstract: A system includes a fluid reservoir containing a first fluid, a pair of fluidic channels in fluidic connection with the fluid reservoir, a counter-fluid reservoir having a second fluid that is non-miscible with the first fluid, and a pump connected to the fluid reservoir. The pump is configured to pump the first fluid from the fluid reservoir into the pair of fluidic channels. When contained in a vehicle, the system allows for control of the vehicle's orientation. The system may use sensor input to determine when to actuate the pump. Each fluidic channel may have a cross-section that varies along its length. The fluidic channels may be geometrically symmetric about the fluid reservoir. The system may be incorporated into a vehicle to control the vehicle's orientation.

  • Patent number: 8943988
    Abstract: A steering control system for ski boat with an inboard motor and a single, non-steerable propeller. The control system augments the traditional aft rudder with a forward rudder (located immediately in front of the propeller), and controls one or both rudders to improve steering when backing and in low forward speed conditions. The control system may control only the forward rudder, while the pre-existing controls operate the aft rudder, or optionally controls both rudders. The rudder angle control algorithm calculates proportional rudder angles based on helm and throttle settings, or optimal rudder angles based on more sensed conditions including the operator's helm and throttle controls, the ski boat's direction and speed, propeller RPM and thrust direction, and each rudder's angle. An electronic controller sends control signals to the rudders to achieve the optimal rudder angles.
