Disclosed is a vehicle side wing anti-collision system, including a telescopic assembly fixed on a vehicle frame; and a collision panel located in a groove of a vehicle side body and provided correspondingly to the telescopic assembly. The groove is provided with a connection hole and the telescopic assembly is extended out of the connection hole towards two sides in a transverse direction of the vehicle to drive the collision panel to extend out of the groove till protruding from the vehicle side body when the collision panel is subjected to a collision. Through the telescopic assembly and the collision panel, protection layers are formed on two sides of the vehicle, and thus the anti-collision ability of the vehicle side wing is enhanced.

A motor vehicle has an electric drive machine for driving the motor vehicle and a coupling mechanism which can be switched at least between a coupling position, in which the electric drive machine is coupled to a drive wheel so as to transmit torque, and a decoupling position in which the electric drive machine is decoupled from the drive wheel. A parking lock device has at least one parking lock element that can be moved between a parking lock position, in which the at least one parking lock element at least indirectly blocks a rotation of the drive wheel, and an unlocking position in which the at least one parking lock element releases the rotation of the drive wheel. An actuation device with an actuator is designed to actuate a clutch of the coupling mechanism, which clutch has at least one switching element and is used to switch between the coupling position and the decoupling position, and is designed to move the at least one parking lock element between the parking lock position and the unlocking position. The switching element has a retaining region preventing the parking lock element from moving into the parking lock position as long as the lock has not been adjusted to the coupling position.

A power transfer unit for a front wheel drive (FWD) vehicle includes a housing, a rear wheel drive gear shaft having a first end section configured to be selectively connected to a FWD transmission, a second end section including a gear member, an intermediate drive shaft having a first end configured to be operatively connected to the FWD transmission, a second end configured to be connected to a front wheel, and an intermediate portion having a gear element. A locking member is mounted to one of the rear wheel drive gear shaft and the intermediate shaft. The locking member is selectively shiftable between a first position, wherein the intermediate drive shaft is independent of the rear wheel drive gear shaft, and a second position wherein the gear member is operatively connected to the gear element.

Methods and systems are provided for a motorized disconnect operable to selectively engage and disengage two rotating components of a vehicle drivetrain. As one example, a motorized disconnect system is provided that operates via an electric motor and includes a shifter assembly with an oscillating gear track and cam profile for rotating the shifter assembly while moving it in an axial direction to selectively couple two rotating components.

A four-wheel drive vehicle includes a friction clutch that transmits a driving force to rear wheels, a hydraulic circuit including a control valve that reduces a pressure of hydraulic oil discharged from a hydraulic pump down to a control pressure corresponding to a control current, and the cylinder and a piston that receives the oil from hydraulic circuit the to press the friction clutch. In the hydraulic circuit, a ratio of an change amount in a feeding pressure to the cylinder to an change amount in the control current, when the feeding pressure to the cylinder is lower than a predetermined value, is lower than when the feeding pressure applied to the cylinder is equal to or higher than the predetermined value. The control apparatus controls a pressure of the hydraulic oil fed to the cylinder lower than the predetermined value when switching the driving state.

An axle disconnect system for drive axles that utilizes an engagement spring, an electric motor and a slidable gear. The motor is connected to the slidable gear which moves along threads thereby engaging or disengaging clutch teeth on a first side gear which selectively engages a second side gear. The engagement spring is located between a bearing and the first side gear wherein when engagement is desired, but blocked by misalignment of the teeth, the engagement spring can apply a load to allow for engagement once alignment of the teeth is achieved. The use of a second engagement spring allows for the disengagement of the system when disengagement is typically blocked due to high driveline torques without having to reapply current to the motor

A vehicle covering system that may include a cover having a first fold and a last fold, a first arm and a second arm, an arm (opening/closing) mechanism to open and close the first arm and the second arm, a folding mechanism to fold and unfold the cover; and a control system to cause the opening/closing mechanism to open the first arm and the second arm from a closed position to an opened position and cause the arm mechanism to close the first arm and the second arm from an opened position to a closed position, and cause the folding mechanism to fold and unfold the cover when the first and the second arms are in an opened position.

A drum cam is connected to a first annular member in a ball cam provided on a rear wheel-side output shaft. Furthermore, linear motion of a second annular member in the ball cam provided on the rear wheel-side output shaft is transmitted to a front wheel-driving clutch via a first transmission mechanism.
