  • Publication number: 20230202632
    Abstract: A control apparatus for a plurality of outboard motors 4, 5 spaced apart at predetermined intervals in a width direction of a hull 2, comprises a first steering unit 26 that adjusts a steering angle of the first outboard motor 4, a second steering unit 26 that adjusts a steering angle of the second outboard motor 5, and a control unit 30, 40 that controls the first steering unit and the second steering unit such that the hull moves or turns in a direction in accordance with a steering instruction of an operator by differentiating the control of the steering angle of the first outboard motor from the control of the steering angle of the second outboard motor when propulsion of either the first outboard motor or the second outboard motor cannot be obtained.

  • Patent number: 9199632
    Abstract: A control device for a hybrid vehicle includes a portion determining whether an engine torque is necessary, a portion controlling a motor to make a motor torque be a target torque, an engine rotation speed control portion controlling an engine output shaft to rotate at a target engine rotation speed for sudden start/reacceleration while the clutch being disengaged after starting the engine and before an actual rotation speed of the engine output shaft exceeds a reference target engine rotation speed in a case where the engine torque is necessary, a control portion engaging the clutch after the actual rotation speed exceeds the reference target engine rotation speed, and a portion controlling the engine so that the engine torque is assumed to be a target torque by canceling the control by the engine rotation speed control portion after the actual rotation speed exceeds the reference target engine rotation speed.

  • Patent number: 8568270
    Abstract: A gear shift control device for controlling a hybrid vehicle drive system including an engine, an automated transmission, a clutch, and a motor generator, includes a torque indication device for indicating a driver request torque determined in accordance with an operation amount of an accelerator operated by a driver, a power generation interruption device changing a vehicle state to an engine driven state using all of the engine torque when a preliminary gear shift condition is satisfied in a state where the engine drives a driving wheel and the motor generator is actuated to generate an electric power, and a gear shift control device reducing the engine torque and generating an assist torque by actuating the motor generator, disconnecting the clutch, and returning the clutch to a connected state after changing gear sets of the gear train when a gear shift condition of the automated transmission is satisfied.
