An active differential for the controlled distribution of a drive torque generated by a drive motor to two drive shafts includes a planetary gear train configured to couple the two drive shafts to a drive shaft of the drive motor, and a distributor motor including a distributor shaft. The distributor motor produces a torque, with a distribution of a drive torque to the two drive shafts being dependant on the torque produced by the distributor motor. The distributor shaft and the planetary gear train are coupled by a coupling device which only transmits a torque from the planetary gear train to the distributor shaft when a rotational speed difference between rotational speeds of the two output shafts exceeds a predetermined limit value and when a connection condition depending on an operating condition of the distributor motor is satisfied.

An active hood apparatus for a vehicle includes a hood configured to cover an engine compartment of vehicle, and at least one hinge device configured to rotatably connect a rear end portion of the hood to a vehicle body. The hinge device includes a fixing bracket fixed to the vehicle body. A rotation bracket is provided such that a rear end thereof is rotatably connected to a rear end portion of the fixing bracket. A hood bracket is fixed to an inner surface of the hood and fixed to the rotation bracket by a first breaking pin. A connecting link provided such that opposite ends thereof are rotatably connected to a rear end portion of the hood bracket and a middle portion of the rotation bracket respectively. An actuator is configured to push up the connecting link in the event that a collision occurs.

A transfer case includes an input shaft, a primary output shaft, a secondary output shaft, and an actuator. The primary output shaft is coupled to the input shaft with a gear reduction mechanism. The secondary output shaft is selectively coupleable to the primary output shaft with a secondary torque transfer mechanism. The actuator includes a first actuation mechanism, a second actuation mechanism, and a driver gear assembly. The first actuation mechanism is configured to operate the gear reduction mechanism. The second actuation mechanism is configured to operate the secondary torque transfer mechanism. The drive gear assembly includes a gear plate member, a sense plate member configured to engage the first actuation mechanism, and a hub member configured to engage the second actuation. The sense plate member and the hub member are independently coupled to the gear plate member to rotate in unison with the gear plate member.

The invention relates to a flap control device for a motor vehicle comprising at least one flap (4, 8) and an actuator (2) moving said at least one flap (4, 8) between a closed and open position. The device is characterized in that said flap (4, 8) is able to be detached from said actuator (2) in the event of failure of said actuator (2). The invention also relates to a frame (3) comprising a device as defined hereinabove.

A control system for a hybrid vehicle configured to promptly disengage a clutch for halting an engine is provided. A clutch device comprises a reciprocating member having tapered reciprocating teeth, and a rotary member having tapered teeth opposed to the tapered rotary teeth. A controller is configured to turn off an actuator to eliminate the electromagnetic attraction thereby allowing the engine to be started, and to apply a torque of the first motor to the clutch device after the actuator is turned off thereby disengaging the reciprocating teeth from the rotary teeth.

A military vehicle including an engine coupled to the chassis for providing mechanical power to the military vehicle, a motor/generator coupled to the engine, and an energy storage system including a battery electrically coupled to the motor/generator. The military vehicle is operable in a silent mobility mode with the engine inactive and the energy storage system providing power to the motor/generator to operate the military vehicle. The motor/generator and the battery are sized such that electrical power generation through engine drive of the motor/generator is greater than the power depletion through operation of the military vehicle in the silent mobility mode. The motor/generator can charge the energy storage system while the military vehicle is driving or stationary.

A driveline including a motor/generator configured to receive power from an engine and output power to a tractive element, an accessory drive configured to receive power from the engine and output power to an accessory, and an energy storage system including a battery, the energy storage system electrically coupled to the motor/generator and the accessory drive. The driveline is operable in a charge mode with the motor/generator and the accessory drive providing electrical power to the energy storage system. The driveline is operable in a silent mobility mode with the energy storage system providing electrical power to the motor/generator and the accessory drive to operate the military vehicle.

Each of a first clutch and a second clutch is, for example, an electromagnetic clutch that is operated by an electromagnetic actuator, and is supplied with electric power from the same in-vehicle battery as a starter motor of an engine. An electronic control unit is configured to not change a drive mode during a stop of the engine, and, after a predetermined period has elapsed from a start of operation of the starter motor at a startup of the engine (for example, the startup has completed) and a battery voltage has been recovered, change the drive mode to any one of a two-wheel drive mode and a four-wheel drive mode with the first clutch and the second clutch.

A solenoid system for a vehicle can include an electromagnetic device, permanent magnet, and sensor. The electromagnetic device can include a housing, armature, and solenoid to move the armature axially relative to the housing. When the armature is in an extended position, a first end of the armature can extend further in a first direction relative to the housing than when in a retracted position. The sensor can be fixedly coupled to the housing and can detect a magnetic field of a permanent magnet based on the position of the armature.
