Abstract: 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.

Abstract: A method and a system for controlling a propulsive power output applied to a propeller shaft of a ship. The ship includes the propeller shaft and a propulsive power source connected to the propeller shaft. A control signal for producing with the propulsive power source a propulsive power is varied within an interval limited by an upper control limit value and a lower control limit value. If a current value of an operational parameter of the ship reaches a first parameter limit value, the upper control limit value is reduced. Thus, the propulsive power source may be prevented from applying a too high power output to the propeller shaft, which would be unfavourable for the ship.
