    摘要： Detecting a rotation state of a worm wheel side with good accuracy while allowing play between an armature-shaft-side coupling member and a worm-shaft-side coupling member. The armature-shaft-side coupling member is provided together rotatably to the other end of an armature shaft; the worm-shaft-side coupling member is provided together rotatably to one end of a worm shaft; the armature-shaft-side coupling member and the worm-shaft-side coupling member are coupled together rotatably; and a sensor magnet is provided together rotatably to the worm-shaft-side coupling member. Therefore, the rotation state of the worm shaft can be detected with good accuracy. Even if the play is provided between the armature-shaft-side coupling member and the worm-shaft-side coupling member, this play does not affect the accuracy of detection of the rotation state of the worm shaft, thereby bringing no problem regarding accuracy of detection of a rotation state of a worm wheel side.

    摘要： A power supply terminal 76a and a ground terminal 76b are respectively disposed on both sides of a connector junction 72 in longitudinal direction, and the control terminals 77a to 77f are disposed between the power supply terminal 76a and the ground terminal 76b, arranged in two rows in longitudinal direction of the connector junction 72, and arranged in three rows in lateral direction of the connector junction 72. Therefore, it is possible to separate the power supply terminal 76a from the ground terminal 76b. And it is possible to reduce the connector junction 72 in size while securing a sufficient air gap (distance L) between the power supply terminal 76a and the ground terminal 76b. Further, it is possible to reduce the power window motor in size.

    摘要： A vehicle 1 has a torque coupling 8, which is located in a driving power transmission system for transmitting the torque of an engine 2 to front and rear wheels 13f, 13r. The torque coupling 8 changes the torque distribution by adjusting the frictional engaging force of an electromagnetic clutch 16. The vehicle 1 also has a 4WD ECU 21 (CPU), which controls the operation of the torque coupling 8 based on the driving state. The 4WD ECU 21 (CPU) estimates a transfer case oil temperature Tptu. When the transfer case oil temperature Tptu is higher than or equal to a first predetermined transfer case oil temperature KTptu1, the 4WD ECU 21 executes overheat prevention control. When the deviation ΔA between an estimated vehicle acceleration Ae, which is computed based on a predetermined vehicle weight M and a driveline torque τd of the engine 2, and the actual vehicle acceleration Av is greater than or equal to a first predetermined deviation KΔA1, the 4WD ECU 21 (CPU) estimates the transfer case oil temperature Tptu to be higher. This allows the control mode of the torque coupling 8 to be smoothly switched to the overheat prevention control.

    摘要： A four-wheel-drive vehicle includes: a drive source which generates torque forming a driving force of the vehicle; a driving force transmission system which transmits the torque of the drive source to main driven wheels and auxiliary driven wheels; and a dog clutch provided in the driving force transmission system and capable of transmitting the torque to an auxiliary driven wheel side by engagement of a recess portion and a protruding portion. The vehicle further includes: a determination unit which determines whether a friction coefficient of a road surface is lower than a predetermined value based on an index value relating to the friction coefficient of the road surface; and a control unit which generates a control signal which causes engagement of the dog clutch before the vehicle starts when the determination unit determines that the friction coefficient of the road surface is lower than the predetermined value.

    摘要： When determining that a vehicle is not skidding, the ECU carries out tight corner control if vehicle speed is smaller than the upper limit value of the vehicle speed range corresponding to the starting state of the vehicle and the steering wheel turning angle of a steering wheel is greater than or equal to the minimum value of the steering wheel turning angle at which the tight corner braking phenomenon may occur. When determining that the vehicle is skidding, the ECU inhibits the tight corner control even if the vehicle speed is smaller than the upper limit value and the steering wheel turning angle is greater than or equal to the minimum value of the steering wheel turning angle at which the tight corner braking phenomenon may occur.
