A vehicle includes a motor, a second drive source, and a drive controller. The motor is a first drive source configured to drive wheels. The motor has a plurality of switchable modes that differ in at least one of a number of poles or a type of torque for rotating a rotor. The second drive source is configured to drive the wheels in parallel with the motor. The drive controller is configured to set, during switching of the modes, a target driving force of the second drive source to be larger than a target driving force of the second drive source before the switching of the modes.

Vehicle

A driving system includes an engine, a motor generator, an output unit, a power transmission mechanism, and a controller. The output unit outputs at least one of an engine driving force generated by the engine or a motor driving force generated by the motor generator. The power transmission mechanism selects a first drive mode in which both of the engine driving force and the motor driving force are transmitted to the output unit, and a second drive mode in which only the engine driving force is transmitted to the output unit. The controller controls the power transmission mechanism to select the first drive mode when a first fuel consumption rate of the engine in the first drive mode is or is estimated to be lower than a second fuel consumption rate of the engine in the second drive mode.

Driving system

A vehicle control apparatus includes a controller that selects an electric vehicle (EV) mode where an output clutch is disengaged and a wheel is driven by a motor, or a hybrid electric vehicle (HEV) mode where the output clutch is engaged and the wheel is driven by an engine and the motor. The controller engages the output clutch during the EV mode to adjust a gear ratio of a continuously variable transmission, and switches, in accordance with a battery state, an adjustment mode for the gear ratio, during the EV mode, between a first adjustment mode that allows the gear ratio to be adjusted in accordance with a vehicle speed, and a second adjustment mode that allows the gear ratio to be adjusted to and kept at a reference gear ratio smaller than a lowest speed gear ratio regardless of the vehicle speed.

Vehicle control apparatus

A vehicle control apparatus for a vehicle provided with an engine, a continuously variable transmission (CVT) coupled to an output shaft of the engine, a motor coupled to a wheel, and an output clutch that transmits power from an output shaft of the CVT and the motor to the wheel includes a controller that is able to switch and execute either of an EV mode that allows, upon disengagement of the output clutch, power outputted from the motor to drive the wheel, and an HEV mode that allows, upon engagement of the output clutch, power outputted from the engine and the motor to drive the wheel, and that, in an adjustment of a gear ratio of the CVT during the EV mode, engages the output clutch and adjusts the gear ratio of the CVT, and thereafter disengages the output clutch before the gear ratio reaches a target gear ratio.

A vehicle includes an engine; a continuously variable transmission; an output clutch disposed between the continuously variable transmission and the drive wheel; a drive motor coupled between the output clutch and the drive wheel; a traveling mode controller; and a speed ratio controller. In a case where required driving power based on an accelerator position is less than a first threshold, the traveling mode controller switches a traveling mode to a first traveling mode. In a case where the required driving power is equal to or greater than the first threshold, the traveling mode controller switches the traveling mode to a second traveling mode. In a case where the required driving power is less than the first threshold and equal to or greater than a second threshold, the speed ratio controller causes a speed ratio of the continuously variable transmission to change depending on a vehicle speed.

An optical image stabilizer includes a base member, a movable member that is disposed at the base member and moves along a plane orthogonal to an optical axis, a movable-member driving portion that is disposed at the base member and the movable member, and moves the movable member in a direction orthogonal to the optical axis, and a regulator that regulates a movement of the movable member along the plane orthogonal to the optical axis. The regulator regulates the movement of the movable member with two movement paths, which are a linear movement path along which the movable member moves in a direction orthogonal to the optical axis and a rotation path along which the movable member rotates around a point on the linear movement path.

Optical image stabilizer and lens driving apparatus

A lens driving device includes a base member, a movable member that is disposed at the base member and moves in a plane that is orthogonal to an optical axis, a first driving portion that moves the movable member in a direction that is orthogonal to the optical axis in accordance with image shake, a lens frame that is mounted to the movable member and moves in a direction of the optical axis, a second driving portion that moves the lens frame in the direction of the optical axis and includes a first magnet that is secured to the movable member and a first coil that is secured to the lens frame, and a Hall element that is disposed so as to oppose the first magnet in the direction of the optical axis and detects a change in a magnetic field of the first magnet.

Lens driving device

A barrier device of the present invention includes a cover defining a front aperture, a base defining a rear aperture, an annular gap formed between a rear end face of the front aperture and a front end face of the rear aperture, a barrier member movably provided through the gap between a closed position and an opened position, and a seal member sealing the gap. The seal member is provided over an entire circumference of the clearance and formed such that, when the barrier member is in the opened position, the seal member seals the gap with a part thereof being in contact with the barrier member, and when the barrier member is in the closed position, the seal member deforms to make contact with a surface of the barrier member. This enables the barrier member to open and close smoothly, and reliably prevents penetration of dirt, dust, moisture or the like through the gap.
