A method for automatically starting and stopping engine(s) of a vessel based on the position of a handle. Automatic starting occurs by activating an ignition circuit, receiving a signal indicating handle position, and providing a signal to start the engine when the handle is out of neutral position. A signal to shift the transmission into gear is sent when the handle is in an idle position. Automatic stopping of the engine includes receiving a signal the handle is in neutral, receiving status information of the engine, and providing a signal to stop the engine when the handle is in neutral and either the engine is not running or at least one of a number of conditions are met. A shutoff timer may delay auto stop of the engine, which may reset whenever any of the conditions ceases to be true.

Systems and methods for operating an engine that may selectively enter and exit a fuel cut-off mode are described. In one example, the method holds the engine in the fuel cut-off mode even though a propulsive effort pedal is applied. An electric machine may provide torque to a vehicle driveline while the engine is in the fuel cut-off mode.

Systems and methods for operating an engine that may be selectively automatically stopped and started are described. In one example, the method adjusts an amount of time that the engine may be inhibited from automatically stopping based on driver inputs such as driver demand pedal position, vehicle speed, and braking torque.

A method and system for operating a vehicle that includes a plurality of engine starting devices and an internal combustion engine is described. In one example, the method selects one of a plurality of engine starting devices to start an engine based on durability metrics of each of the plurality of engine starting devices. In addition, engine starting device selection may be based on calibration parameters that are generated via a server that is external to the vehicle.

A vehicle idling stop control device has switches that detect an operation of opening a driver's door and an unbuckling of a driver's seat belt as disembarkation operations by a driver. When a disembarkation operation performed by the driver is detected during an idling stop, the idling stop is cancelled and the engine is restarted upon detecting a disembarkation operation performed by a driver during the idling stop. Also, restarting of the idling stop is prevented due to ending of the disembarkation operation performed by the driver until after the vehicle starts traveling. Thus, unnecessary automatic stopping and automatic restarting of the engine are thereby avoided when the vehicle sets off without the driver actually exiting the vehicle.

Methods and systems are provided for restarting an engine following an engine idle-stop. In one example, a method may include, following a first unsuccessful engine restart attempt, prompting a driver, via a human machine interface (HMI) to apply a brake pedal and upon application of the brake pedal, carrying out one or more restart attempts. If the driver does not apply the brake pedal within the threshold duration, the driver may be prompted to manually restart the engine.

In the case of restarting an internal combustion engine that has been automatically stopped during running, the internal combustion engine is restarted by combustion recovery starting when the rotation speed of the internal combustion engine under the input of a restart request is greater than or equal to a predetermined first rotation speed. In the case of restarting the internal combustion engine that has been automatically stopped during running, the internal combustion engine is restarted by cranking recovery starting when the rotation speed of the internal combustion engine under the input of the restart request is lower than the predetermined first rotation speed. The first rotation speed is set lower at the restart of the internal combustion engine in a sailing stop state than at the restart of the internal combustion engine in a coast stop state.

A method for controlling a start of a vehicle using a controller includes: determining whether revolutions per minute (RPM) of an engine is within a reference range when start of the vehicle is requested; determining whether state data for controlling the vehicle satisfies a control condition for controlling a start of the vehicle when RPM of the engine is within the reference range; determining whether a position value of an accelerator pedal is less than or equal to a reference position value when the state data satisfies the control condition; determining whether a speed of the vehicle is greater than or equal to a reference speed when the position value of the accelerator pedal is less than or equal to the reference position value; and controlling a brake device when speed of the vehicle is greater than or equal to the reference speed.

A method for exiting from a recuperation phase in a parallel hybrid vehicle includes, in a first step, the vehicle is in a recuperation phase, started by means of a trigger, with a predefined recuperation driving demand, and, in a second step, the electric machine is brought to an increased rotational speed during the recuperation phase. In a third step, a phase for departing from the recuperation phase is started by means of a trigger, wherein, in this phase, the internal combustion engine is made available for coupling to the electric machine, such that a target rotational speed determined between the internal combustion engine to be connected and the electric machine for the connection to the transmission input is set, and in parallel, by means of an upshift, a highest possible gear ratio for the connection to the drivetrain is set, in order to satisfy a present driving demand. In a fourth step, the departure from the recuperation phase is completed.

Methods and systems are provided for controlling an engine idle-stop based on upcoming traffic and road conditions. In one example, a method may include receiving data including traffic information and road characteristics immediately ahead of a vehicle from one or more remote sources, and adjusting one or more vehicle thresholds based on the received data. A duration of a prospective engine idle-stop may be estimated based on the received data and an engine idle-stop may be initiated based on the duration of the prospective engine idle-stop and the adjusted one or more vehicle threshold.
