摘要： A hybrid vehicle includes: a driving power source including an engine and an electric motor; a battery that supplies electric power to the electric motor; and a controller that controls the engine and the electric motor according to a temperature of the battery. When a predetermined EV mode condition is satisfied, and a normal-temperature condition in which the temperature of the battery is a threshold or more is satisfied, the controller controls the driving power source in an EV mode in which the electric motor is driven. When the EV mode condition is satisfied, and a low-temperature condition in which the temperature of the battery is less than the threshold is satisfied, the controller operates the electric motor in a state where electric current flows between the battery and the electric motor drives the engine such that the engine generates traveling power transmitted to a driving wheel.

摘要： A control device of a hybrid vehicle includes: a determiner that determines whether or not a predetermined first condition that efficiency is prioritized is satisfied and whether or not a predetermined second condition that output performance is prioritized; and a control unit that controls an engine and an electric motor in accordance with an accelerator manipulation amount and a determination result of the determiner. When the first condition is satisfied, the control unit controls the driving power source such that the driving power source outputs first driving force in a first driving state where the efficiency is prioritized, and when the second condition is satisfied, the control unit controls the driving power source such that the driving power source outputs second driving force larger than the first driving force in a second driving state where the output performance is prioritized.

摘要： A controller of a vehicle is a controller of a vehicle including: a driving source; a driving wheel; a first transmitting structure; a second transmitting structure which is connected to the first transmitting structure so as to be movable relative to the first transmitting structure in a power transmitting direction within a range of a play; a clutch located on the power transmitting path and between the driving source and the first transmitting structure; and a clutch actuator. The controller determines whether or not a relative position of the first transmitting structure relative to the second transmitting structure changes. When it is determined that the relative position changes, the controller controls the clutch actuator to change a power transmission rate such that collision force of one of the first transmitting structure and the second transmitting structure with respect to the other by the change in the relative position is reduced.

摘要： A small watercraft system includes: a watercraft body; a watercraft body manipulation member through which a watercraft body manipulation command is input by an operator; a drive source that allows the watercraft body to plane; a steering device that allows the watercraft body to be steered; and a control device that controls the drive source and the steering device to operate the watercraft body. The control device determines whether a mode switching condition is satisfied, the mode switching condition including an operator's absence condition that the operator is absent from the watercraft body. Upon determining that the mode switching condition is satisfied, the control device executes an operator-absent manipulation mode in which the control device moves the watercraft body by controlling the drive source and the steering device based on an operator-absent manipulation command independent of the watercraft body manipulation command.
