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： A driving force distribution device which controls the engagement forces of electromagnetic clutches and which govern the torque distribution between the driving wheels of a vehicle by calculating a target magnetic flux density and converting the same into a target excitation current. Since the relationship between the target magnetic flux density and the target excitation current changes according to a decrease in the air gaps accompanying wear of the frictional engagement members of the electromagnetic clutches, a relationship between the magnetic flux density and the excitation current is determined by applying current to the electromagnetic clutches when torque distribution control is not being carried out such as when the system is started, and the target excitation current is calculated from the target magnetic flux density based on the determined relationship. Since there is no need to detect dynamic changes in the magnetic flux density, inexpensive devices can be used as magnetic flux density detecting means so contributing to a reduction in the cost.

摘要： In a vehicle in which a torque generated in an engine is transmitted to driven wheels through a torque converter and an automatic transmission, when a speed ratio e in the torque converter is equal to or larger than a predetermined value (e.g., 0.85), and the accuracy of estimating a capacity &tgr; of the torque converter is low, an estimated engine torque Ti is multiplied by a torque ratio k of the torque converter to estimate a drive torque Td. When the speed ratio e in the torque converter is smaller than the predetermined value, and a response lag is produced in the transmission of the engine torque, a drive torque Td is estimated from an engine rotational sped Ne and the speed ratio e in the torque converter. During shifting of the automatic transmission, a drive torque Td is estimated from a wheel speed V. Thus, a correct drive torque can be estimated.

摘要： An electromagnetic clutch structure in a driving force distribution system selectively operates right and left electromagnetic clutches so as to transmit torque from the inner turning wheel to the outer turning wheel, thereby assisting turning, or so as to transmit torque from the outer turning wheel to the inner turning wheel, thereby stabilizing vehicle behavior. The right and left electromagnetic clutches each include a coil, a core housing the coils, armatures arranged so as to adjoin the core in the lateral direction, and frictional engagement members arranged on the inside, in the radial direction, of the core. The frictional engagement members are engaged by pressure of a pressure part of the armatures, the pressure part extending further inward in the radial direction than the core.
