摘要： Two sensors are provided on a clutch core. Sensor coils are driven at a high frequency by a high-frequency driving circuit. As the sensors sense a magnetic flux of a magnetic circuit including the clutch core and an armature, the impedance of the sensor coils changes. In accordance with the outputs from the sensor coils at this point, an impedance detecting circuit detects the impedance of the sensor coils. Then, an impedance combining circuit combines the impedance of the sensor coils. On the basis of the combined impedance, a current control circuit controls a current supplied to an exciting coil. Thus, the attracting force of the armature to the core excited by the exciting coil is controlled.

摘要： A vehicle co-operative control system is provided which suppresses the torque steer phenomenon by co-operatively controlling a driving force and/or braking force distribution device and an electric power steering device without changing the control device of the electric power steering device for a vehicle having a specification in which the co-operative control is not carried out or with the introduction of only a minimal change. The control device can also be applied to a vehicle having a specification in which the co-operative control is carried out. In order to achieve this, the steering torque detected by the steering torque detecting device is input into a corrected steering torque calculating device of a first electronic control unit for controlling the driving force and/or braking force distribution device and a corrected steering torque which has been calculated in the corrected steering torque calculating device is input into the second electronic control unit for controlling the electric power steering device. The second electronic control unit controls the electric power steering device based on the corrected steering torque and thus the torque steer phenomenon caused by the driving force and/or braking force distribution device is suppressed.

摘要： The engagement force of an electromagnetic clutch can be precisely controlled at a target engagement force by a simple structure even when an air gap of the electromagnetic clutch varies. An electromagnetic clutch control system includes magnetic flux density sensors, a target engagement force calculating device, a target magnetic flux density calculating device, and a feedback control device. The target magnetic flux density calculating device calculates a target magnetic flux density &phgr;t based on a target engagement force Tt of electromagnetic clutches calculated by the target engagement force calculating device. The current supplied to the electromagnetic clutches is feedback controlled by the feedback control device so that an actual magnetic flux density &phgr; detected by the magnetic flux density sensors agrees with the target magnetic flux density &phgr;t. This allows a target engagement force to be generated in the electromagnetic clutches by making the actual magnetic flux density agree precisely with the target magnetic flux density, even when the air gap varies due to wear of a frictional engagement member, etc. and the relationship between the actual magnetic flux density and the current supplied to the electromagnetic clutches changes.

摘要： An improvement is made to a torque splitting device employing hydraulic clutches so as to avoid any discontinuity in the control even when the properties of the actuating oil such as the pressure and temperature thereof deviate from standard values. For instance, when the oil temperature is low, the target value of the oil pressure for each of the clutches is modified to a lower value. Thus, it becomes possible to make less pronounced any delay in the response of the torque splitting device which may arise due to the sluggishness of the oil as it flows out of the clutch cylinder. The oil pump is typically actuated by a member rotating at a speed proportional to the vehicle speed, and the pressure output of the pump may be inadequate in a low speed range. In such a case, the target value is again reduced so as to reduce any abrupt change in the property of the torque splitting device when the vehicle is accelerated from a low speed. Because the pressure output of the pump normally drops as the oil temperature rises, it is desirable to take into account the oil temperature in this control action as well.
摘要翻译：对使用液压离合器的扭矩分离装置进行改进，以便即使当诸如压力和温度的致动油的性质偏离标准值时，也避免了控制中的任何不连续性。例如，当油温低时，将每个离合器的油压的目标值修改为较低的值。因此，由于油流出离合器气缸时油的迟缓可能导致扭矩分配装置的响应的任何延迟变得不那么明显。油泵通常由以与车速成比例的速度旋转的构件致动，并且在低速范围内泵的压力输出可能不足。在这种情况下，再次降低目标值，以便在车辆从低速加速时减小转矩分配装置的特性的突然变化。由于泵的压力输出通常随着油温的升高而下降，因此在该控制动作中也要考虑油温。

摘要： A feed-forward control section controls, in a feed-forward manner, left and right hydraulic clutches C.sub.L and C.sub.R of a driving force distributing device by presuming such a driving force distribution amount .DELTA.T that a yaw rate corresponding to a turning state of a vehicle is obtained, based on an engine torque, an engine revolution-number, a vehicle speed, a steering angle and a lateral acceleration. On the other hand, a feedback control section calculates a deviation between a reference yaw rate calculated from the vehicle speed and the lateral acceleration and an actual yaw rate detected by a yaw rate sensor, and corrects the driving force distribution amount .DELTA.T calculating in the driving force distributing device in order to converge the deviation into zero. Therefore, even if the driving force distribution amount becomes excessive due to the feed-forward control to produce an over-steering tendency in the vehicle, this over-steering tendency can be eliminated by the feedback control to stabilize the behavior of the vehicle.

摘要： In a torque splitting device for distributing an input torque applied to an input member to a pair of output members adapted to be coupled with right and left driven wheels of a vehicle at an adjustable distribution ratio, the distribution ratio is determined in such a way that the understeer and oversteer tendencies of the vehicle under a positive or negative drive condition while turning a curve is appropriately controlled. In particular, it is highly desirable to prevent an understeer tendency from appearing while turning a curve. Therefore, when the vehicle is under a positive drive condition while tuning a curve, a yaw moment is produced by an appropriate torque distribution which assists the vehicle to turn in such a way that the understeerg condition is canceled. Furthermore, when the vehicle moves on from a positively drive condition to a negative drive condition while turning a curve, a slight oversteer tendency is produced with a minimum time delay so as to avoid any transient phase of an understeer condition from appearing.

摘要： In a vehicle drive system having a torque split arrangement, it is difficult to have all the rotating parts of the system to be properly balanced. In particular, when a rotational speed difference is produced between the two output elements, relatively massive parts which may not be properly balanced may have to be turned at a high speed. According to the present invention, because the power output of the engine is reduced whenever any significant speed difference is produced between the two output elements, no part of the drive system is subjected to any excessive rotational speed, and are therefore not required to have any excessive mechanical strength. This improves the reliability of the system, and reduces the manufacturing cost.
