An evaporative emissions control system includes a first vent valve configured to selectively open and close a first vent, a second vent valve configured to selectively open and close a second vent, a fuel level sensor configured to sense a fuel level in the fuel tank, a pressure sensor configured to sense a pressure in the fuel tank, an accelerometer configured to measure an acceleration of the vehicle, and a controller configured to regulate operation of the first and second vent valves to provide pressure relief for the fuel tank. The controller is programmed to determine if a refueling event is occurring based one signals indicating the fuel level is increasing, the pressure in the fuel tank is increasing, and the vehicle is not moving, and open at least one of the first and second vent valves based on determining the refueling event is occurring.

A fuel system, a method of fueling a vehicle, and a vehicle are provided. The fuel system has a recirculation line connecting a fuel tank to a fuel fill inlet. An ejector is positioned within the recirculation line, and a valve is positioned within a drain line fluidly connecting the ejector to the fuel tank. A pressure sensor is positioned to measure a pressure associated with the drain line between the ejector and the valve. A controller is in communication with the pressure sensor, and the controller configured to, in response to initiation of a refueling event, determine a state of the valve based on the pressure.

A system includes a clutch state module and a clutch torque module. The clutch state module is configured to determine whether a clutch of an electronic limited slip differential is locked or unlocked. The electronic limited slip differential couples an engine of a vehicle to left and right wheels of the vehicle. The clutch torque module is configured to estimate an actual torque transferred by the clutch using a first clutch torque model when the electronic limited slip differential is unlocked, and estimate the actual clutch torque using a second clutch torque model when the electronic limited slip differential is locked. The second clutch torque model is different than the first clutch torque model.

An evaporated gas leak diagnosis method using an active purge pump is provided to detect a leak of the evaporated gas from a canister in a fuel system. The method includes diagnosing a failure of an active purge pump based on a signal generated by a pressure sensor installed on a vent line that extends from the canister to the atmosphere. The active purge pump is mounted on a purge line for connecting the canister with an intake pipe.

An operating device for a vehicle brake system may include a control device and a piston-cylinder unit, at least one chamber of which may be connected to at least one wheel brake via at least one hydraulic line and a valve device that has at least normally open inlet valves or switching valves. The device may further include a pressure source that may be controlled to supply pressure medium to the at least one hydraulic line or to the at least one wheel brake. The control device may control pressure build-up via volume control and/or time control, using inlet valves. The interior or armature chamber of an inlet valve may be connected to a corresponding brake circuit via a hydraulic line, and a valve seat outlet may be connected to a corresponding wheel brake via a hydraulic line.

A fuel tank unit may include a fuel tank, a canister configured to adsorb and desorb vapor generated in the fuel tank, a vapor conduit communicating the fuel tank with the canister, and a full tank fuel level limiting valve device connected to a fuel tank-side end of the vapor conduit. The full tank fuel level limiting valve device includes a full tank fuel level limiting valve and an actuator. The full tank fuel level limiting valve includes a float that is configured to float due to a buoyancy force of fuel in the fuel tank so as to close the full tank fuel level limiting valve when the fuel tank is filled up. The actuator includes a valve closure prevention member that is configured to move and press the float when the actuator is activated, so as to prevent the float from moving in a valve closing direction.

A fuel tank system for a vehicle includes a fuel tank, a fuel supply passage, a canister, an evaporated fuel gas supply passage, a communication passage, a backflow prevention device, first and second pressure measurement devices, and a control device. The fuel tank stores fuel supplied by the fuel supply passage. The canister adsorbs evaporated fuel gas generated in the fuel tank and supplied through the evaporated fuel gas supply passage. The backflow prevention device is provided in a pipe line of the fuel supply passage, and prevents a backflow of the fuel from the fuel tank. The first and second pressure measurement devices respectively measure pressures in the fuel supply passage and the evaporated fuel gas supply passage. The control device diagnoses the communication passage as being blocked when a difference between pressure values measured by the first and second pressure measurement devices exceeds a predetermined value.

A fluid management module, e.g., for a motor vehicle, is disclosed. The fluid management module includes at least two function components and at least one electrical control/regulating device. The control/regulating device includes a circuit board with electrical connectors. The electrical connectors include a plurality of analogue signal input connectors and at least one component field bus connector, each for electrically connecting to a respective function component via a component field bus, and a vehicle field bus connector for electrically connecting to a CAN bus or LIN bus of a motor vehicle. At least the vehicle field bus connector, the component field bus connector and the analogue signal input connectors are electrically connected to a micro-controller of the control/regulating device provided on the circuit board. At least one of the at least two function components is electrically connected to at least one of the electrical connectors.

An object of the present invention is to provide an emergency braking device for an automobile that is capable of preventing a safety-related accident by applying a braking force even when a brake pipe or the like is ruptured. To this end, the emergency braking device for an automobile of the present invention is an emergency braking device for an automobile that is added to an automobile that is braked by a pressure of main brake fluid transferred through a brake pipe when a brake pedal is stepped on and that is instantaneously and automatically switched to an emergency braking device when braking is not performed due to the rupture of the existing (main) brake pipe, or the like. The emergency braking device for an automobile includes a valve unit, an emergency pipe; a pressing part; and a pressure source.

A sensor disposition structure in a seat includes a cushion pad and a board-like member which is disposed under the cushion pad. A concave is formed in an upper surface of the board-like member, and a sensor is disposed in the concave.
