Abstract: The electronic controlled drive apparatus includes: a throttle actuator (11) that opens or closes a throttle of an internal combustion engine in accordance with a target throttle opening degree; a shift actuator (12) that actuates a shift in accordance with a target shift position; an engine rotation number holding unit (step S4) for obtaining an engine rotation number when the target shift position is released and holding the obtained engine rotation number; and a waiting time calculating unit (step S5) for calculating a shift drive waiting time in accordance with the held engine rotation number. In the electronic controlled drive apparatus, counting of the shift drive waiting time is started when the target shift position is released (steps S6 and S7), and the shift actuator is allowed to be drive (step S9) after a lapse of the shift drive waiting time (step S8).

Abstract: A watercraft has an engine and a remote controller. The engine has a throttle valve unit. The remote controller provides a command signal indicative of a position of the throttle valve unit. A watercraft velocity sensor senses an actual speed of the watercraft to provide an actual speed signal. A control data input device selectively provides a control device with a manual mode signal and a constant speed mode signal. The constant speed mode signal is accompanied by a target speed signal. The control device controls the throttle valve unit based upon the command signal in the manual mode. The control device controls the throttle valve unit in the constant speed mode such that an actual speed of the watercraft coincides with the target speed of the watercraft once a state of equilibrium is reached.

Abstract: An electronic controlled drive apparatus includes: a remote control unit 3 for calculating a target throttle opening degree and target shift position based on an inputted position of an operational lever of a remote control device 1; a throttle actuator 11 that opens or closes a throttle of the engine in accordance with the target throttle opening degree; a shift actuator 12 that actuates a shift in accordance with the target shift position; and a throttle actuator control unit 5 for determining whether or not the target shift position is in a shift-in state, and when the target shift position is in the shift-in state, driving the throttle actuator to put the throttle into the small opening degree state. The shift actuator is driven to conduct shift connection after the throttle is put into the small opening degree state.

Abstract: Provided is a network communication apparatus that is capable of, even when each node to be connected is undefined, managing a connection state of the node with ease. The network communication apparatus includes at least one node connected to a network and a management node that manages each of the at least one node. Each of the at least one node includes a data transmission and reception unit for transmitting and receiving data containing an ID field giving contents of the data and a data field giving an entity of the data, and an analyzing unit for analyzing meanings of the ID field and a data field of received data. The management node collects attribute information from each of the at least one node, and assigns and gives a node ID number to each of the at least one node based on the collected attribute information.

Abstract: A controller area network (CAN) communication device capable of securing a guarantee of communication without causing failure to an ID coding system is provided. The CAN communication device is formed such that a plurality of nodes are connected to communication channels in a controller area network (CAN). Each of the nodes includes a transmitting/receiving unit for transmitting and receiving data including a CAN-ID field formed of bits containing function information, an ID-setting unit for setting predetermined function information to the bits of the CAN-ID field contained in the data transmitted from the transmission/reception unit, and an ID-analyzing unit for analyzing the predetermined function information set in the CAN-ID field included in the data when the data containing the predetermined function information set by the ID-setting unit has been received by the transmission/reception unit.

Abstract: An EGR valve control apparatus is provided which is capable of controlling an amount of exhaust gas to be recirculated in a precise and proper manner by using a step motor, as well as improving the durability of an EGR valve. The EGR valve control apparatus adjusts an opening of the EGR valve for opening and closing an exhaust gas recirculation passage connecting between an exhaust passage and an intake passage by means of the step motor.
