摘要： An engine system provided to a vehicle having an accelerator pedal is provided. When an engine operation range is determined to shift to a first range (where an electromagnetic clutch is disengaged) from a second range (where the clutch is engaged) after an opening of the accelerator pedal increases at a rate below a given reference rate, the clutch is switched from ON to OFF after a given basic stand-by period passes from the shift. When the engine operation range is determined to shift from the second range to the first range after the accelerator pedal opening increases at the given reference rate or above, the clutch is switched from ON to OFF after a given acceleration stand-by period (longer than the basic stand-by period by a given added period) passes from the shift.

摘要： A vehicle drive device (1) is disclosed that includes a shift detent mechanism (90); an actuator (74) that generates drive power for allowing the shift detent mechanism to operate; a sensor (135) that generates sensor information indicating an amount of operation of the shift detent mechanism; a control part (153) that controls the actuator; and a clutch (30) that is synchronized with operation of the shift detent mechanism, and when the control part changes a state of the clutch, the control part performs feedback control of the actuator based on a relationship between a target value for an amount of operation of the shift detent mechanism and the sensor information, and before completing the change in the state of the clutch, the feedback control ends and operation of the actuator stops.

摘要： The present disclosure relates to a method for defining a clutch slipping point position (Xsp) of a clutch in a gearbox comprising an input shaft arranged to be braked by a braking means. The method includes determining if the clutch is dragging when the clutch is fully disengaged. The method includes when it is determined that the clutch is dragging, applying the braking means with a predetermined brake torque (Tb) and so that the input shaft is not rotating; and thereafter: moving the clutch from the fully disengaged position towards an engaged position; determining when the input shaft starts to rotate with a predetermined rotation value indicative of a rotational speed of the input shaft; registering a clutch position (Xb) in which the clutch is positioned when the predetermined rotation value is reached; using a clutch transfer characteristics of the clutch, Tb, and Xb to define the clutch slipping point position (Xsp).

摘要： In a vehicle equipped with an engine and a shift control mechanism that switches a shift position by rotating a detent plate with an electric actuator, an electronic control device is an electronic control device including a reference position learning unit that executes a learning of a reference position of the actuator that serves as a reference for switching the shift control mechanism by the actuator when a starting condition that is set in advance is satisfied, and includes a drive wheel rotation suppression unit that suppresses a rotation of a drive wheel of the vehicle while the learning of the reference position is being executed by the reference position learning unit.

摘要： A vehicle includes a powertrain having a powerplant and a clutch that selectively couples the powerplant to an axle. A controller is programmed to, in response to the powertrain being in a power-limiting routine, command a torque to the powerplant based on an error between a target slip of the clutch and a slip of the clutch.

摘要： An apparatus for controlling a hybrid vehicle and a method thereof are provided. The apparatus includes a hybrid starter & generator (HSG) controller that determines whether an HSG has failed, and a hybrid vehicle controller that controls reverse drive by controlling locking up an engine clutch and maintaining a main relay of a battery to be continuously turned on, based on whether a request for the reverse drive is input from a user. The hybrid vehicle controller changes and applies a vehicle torque control calculation method based on a state of charge (SoC) of the battery, when the HSG has failed.

摘要： A magnetic clutch for actuating a disconnect clutch includes an axis of rotation, an axially fixed stator, an axially movable armature, a torque-axial force converter unit with an armature side and a bearing side, and a rotary brake. The axially movable armature is axially retainable on the stator by a magnetic force from a power supply. The torque-axial force converter unit acts in an antagonistic manner to the magnetic force to hold the armature at an axial distance from the stator. The rotary brake is for effecting a rotational speed difference between the armature side and the bearing side. Other aspects of the disclosure include a disconnect clutch for an internal combustion engine in a hybrid drive train, a hybrid drive train, and a method for controlled closing of the disconnect clutch.

摘要： This clutch control device includes an engine (13), a transmission (21), a clutch device (26) configured to connect and disconnect motive power transmission between the engine (13) and the transmission (21), a clutch actuator (50) configured to drive the clutch device (26) and change a clutch capacity, a clutch operating element (4b) configured to enable the clutch device (26) to be manually operated, and a control unit (60) configured to calculate a target value (Pt) of a control parameter (Ps) of the clutch capacity in accordance with an amount of operation on the clutch operating element (4b). When the clutch device (26) is operated on a connection side according to an operation on the clutch operating element (4b), the control unit (60) is configured to set the target value (Pt) to a quick connection target value (Pmax) obtained by making a change to the connection side of the clutch device (26) with respect to an operation correspondence target value (Pv) according to the amount of operation on the clutch operating element (4b) if a speed of the operation on the clutch operating element (4b) is higher than or equal to a predetermined specified speed (Sp1).
