The present invention discloses a locking device, a power assembly, a power transmission system and a vehicle. The locking device includes: a first flange, the first flange being adapted to be fixed on the first shaft; a second flange, the second flange being adapted to be fixed on the second shaft; a synchronizing ring, the synchronizing ring being normally connected to the first flange to be adapted to rotate synchronously with the first flange, and the synchronizing ring being slidable relative to the first flange; and a driving component, the driving component selectively pushing the synchronizing ring to slide from an unlocked position to a locked position in an axial direction of the first flange. When the synchronizing ring is in the locked position, the synchronizing ring is connected to the second flange be adapted to rotate the second flange synchronously with the first flange. When the synchronizing ring is in the unlocked position, the synchronizing ring is separated from the second flange. The locking device according to embodiments of the present invention can realize the single-way locking function, and is simple in structure.

A vehicle drive device including an engagement pressure flow channel, a lubrication flow channel, a first pump having a discharge port connected to the engagement pressure flow channel, a second pump, and a flow channel control valve. The flow channel control valve selectively switches flow channels between a first state in which an outflow destination of oil discharged from the second pump is the engagement pressure flow channel and a second state in which the outflow destination is the lubrication flow channel. When a failure in which the flow channel control valve is fixed in the second state has occurred, a control device for a vehicle control device performs fail-safe control in which a rotational speed of at least one of an internal combustion engine and a rotating electrical machine is increased to supply oil to the engagement pressure flow channel by the first pump.

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.

The present invention discloses an operating fluid container for a motor vehicle, wherein the operating fluid container comprises a fill level sensor, a tank control device and an electrically and/or electromagnetically actuable actuator; the tank control device is connected to the actuator by means of a first data exchange connection and to the fill level sensor by means of a second data exchange connection; the fill level sensor is designed to transmit data representing a fill level of the operating fluid container to the tank control device via the second data exchange connection; the tank control device is designed to transmit a filling stop signal to the actuator via the first data exchange connection upon receiving data which represent a predetermined fill level of the operating fluid container; and the actuator initiates the termination of a filling procedure of the operating fluid container upon receiving the filling stop signal.

A solenoid valve includes a valve that regulates the entrance and exit of oil, and a solenoid that operates the valve. The valve includes a hollow holder extending in one direction, ports including a supply port, a control port, and a discharge port, a passage that is formed in the holder and extends in the longitudinal direction of the holder, wherein a chamber connecting the supply port and the discharge port is formed in the middle of the passage, a spool movably installed in the passage, a channel that is formed in the spool and has one end connected to the control port and the other end connected to the chamber, a control land that divides the chamber into a supply chamber and a discharge chamber, and a spring that is installed between the holder and the spool to elastically support the spool.

A fuel tank system constructed in accordance to one example of the present disclosure includes a fuel tank, a purge canister and a valve assembly. The valve assembly can be fluidly coupled between the fuel tank and the purge canister. The valve assembly can include a main valve and a safety check valve. The main valve can have a main valve first port fluidly coupled to an outlet of the fuel tank and a main valve second port fluidly connected to the purge canister. The safety check valve can be configured to move from an open position to a closed position upon a pressure drop at the fuel tank outlet exceeding a predetermined threshold. The safety check valve can have a safety check valve first port fluidly coupled to the outlet of the fuel tank and a safety check valve second port fluidly coupled to the purge canister.

A fuel tank vent valve includes a venting apparatus for regulating discharge of fuel vapor from a fuel tank and admission of outside air into a fuel tank. The vent valve is used to regulate pressure in a fuel tank.

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 microcomputer of a driving force distribution control device detects a maximum current value among values of an upper current acquired during a predetermined period, and determines that an overcurrent abnormality has occurred in the driving force distribution control device when the maximum current value is equal to or larger than an abnormal current threshold value and a time, for which the maximum current value is equal to or larger than the abnormal current threshold value, is equal to or larger than an abnormality detection time. Then, the microcomputer performs off control to turn off a relay, and notifies a driver of occurrence of the overcurrent abnormality using a notification unit.

A discharged liquid circulation system, an electric drive power assembly and an automobile are disclosed. The discharged liquid circulation system includes a first liquid collecting tank and a second liquid collecting tank, the first liquid collecting tank and the second liquid collecting tank being in communication communicated with each other, and a first liquid level sensor and a second liquid level sensor are provided in the second liquid collecting tank; an electromagnetic reversing valve that includes a first liquid inlet and a second liquid inlet that extend into the first liquid collecting tank and the second liquid collecting tank through two pipes, respectively; and an electric pump, wherein a liquid inlet of the electric pump is connected to a liquid outlet of the electromagnetic reversing valve through a first pipe, and a liquid outlet of the electric pump is connected to a corresponding liquid spray nozzle through a second pipe.
