The invention relates to a method for operating a motor vehicle, in which by at least one ultrasonic sensor, operated in the active operation mode, of an ultrasonic sensor device of the motor vehicle ultrasonic waves are emitted into an environmental region of the motor vehicle, wherein the motor vehicle as hybrid vehicle is equipped with an internal combustion engine (and an electric drive machine and in the active operation mode of the ultrasonic sensor arranged on a rear part of the motor vehicle the motor vehicle at least temporarily is operated by means of the electric drive machine. The invention also relates to a motor vehicle.

In a vaporized fuel processing apparatus in which fuel vapor within a fuel tank is adsorbed by a canister, the adsorbed vaporized fuel is drawn to an engine, a closing valve is provided connecting the fuel tank and the canister for controlling communication between the fuel tank and the canister, and a purge valve is provided connecting the canister and the engine for controlling communication between the canister and the engine. The vaporized fuel processing apparatus includes an internal pressure sensor configured to detect a pressure of a space within the fuel tank as an internal pressure, and a closing valve control means configured to open the closing valve for supplying an atmospheric pressure to the fuel tank via the canister when the sensor detects that the internal pressure of the fuel tank is negative, while the purge valve is closed. Therefore, the air/fuel ratio is prevented from being disturbed.

Methods and systems are provided for aging a new plastic fuel tank in a vehicle. In one example, during a plug-in event to recharge a battery of the vehicle, the fuel tank is isolated and the fuel pump is actuated to agitate fuel within the tank and increase fuel vapors until the plastic fuel tank becomes aged to a predetermined degree by fuel vapors generated therein. In this manner, the fuel tank is aged more rapidly, resulting in more accurate fuel level readings and less noise and vibration.

A sensor adapter assembly configured to couple a vapor pressure sensor to a fuel tank includes a base housing configured to couple to the fuel tank, and an insert adapter coupled to the base housing. The insert adapter defines a sensor insertion aperture configured to provide fluid communication to a space inside the fuel tank. The insert adapter is configured to couple to the vapor pressure sensor such that at least a portion of the vapor pressure sensor extends through the sensor insertion aperture into the space inside the fuel tank.

Methods and systems are provided for identifying misfueling of a vehicle fuel tank with a fuel that is not of a correct type for the vehicle being refueled. In one example, and method may include routing fuel vapors from a vehicle fuel tank to a fuel vapor storage canister during a refueling operation, and responsive to an indication of misfueling, where the indication of misfueling includes a monitored pressure in the fuel tank below a misfueling pressure threshold, and where the misfueling pressure threshold is adjusted as a function of expected pressure in the tank during refueling, actively terminating the refueling event. In this way, addition of an incorrect fuel type to a vehicle fuel tank may be indicated prior to completion of refueling, which may thus alert a vehicle operator of the misfueling, and which may prevent further complications arising from operating the vehicle with an incorrect fuel type.

A diagnostic system of a vehicle includes an energy absorber sandwiched between a front bumper fascia and a front bumper reinforcement of the vehicle. A sensing tube is located between a portion of the energy absorber and the front bumper reinforcement. A first pressure sensor and a second pressure sensor measure a first pressure of air and a second pressure of air within the sensing tube, respectively. An actuator is configured to actuate and vary a pressure within the sensing tube. A diagnostic module is configured to selectively diagnose the presence of a fault with the sensing tube based on at least one of: a first change in the first pressure in response to actuation of the actuator; and a second change in the second pressure in response to the actuation of the actuator.

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.

A fuel tank comprises a circular column-shaped fuel tank body, a handle, and a lock mechanism. The circular column-shaped fuel tank body is provided so as to be capable of being detachably attached to a fuel-powered device. The handle is formed on one end side in a length direction of the fuel tank body. The lock mechanism is capable of switching between a locked state in which the fuel tank body cannot be removed from the fuel-powered device, and a lock-released state in which the locked state has been released, due to the fuel tank body being rotated in a circumferential direction in a state of being installed to the fuel-powered device.

A tire inflation system for a work vehicle includes a controller with a memory and a processor, where the controller is configured to perform an iterative process until a stopping condition is reached. The iterative process includes receiving a tire pressure sensor signal indicative of a tire pressure a one tire, receiving a draft load sensor signal indicative of a draft load on the work vehicle, determining a draft load difference between the draft load and a maximum draft load, and outputting a target tire pressure output signal indicative of instructions to adjust the tire pressure of the tire in response to determining that the draft load difference is greater than or equal to a first threshold value. The stopping condition includes determining that the draft load difference is less than the first threshold value, determining that a variation in the draft load between iterations is less than a second threshold value, determining that a maximum runtime is reached, and determining that a maximum number of iterations is reached.

A system (40) for transmitting control pressures and/or working pressures from a wheel-hub pressure medium supply (20, 21, 22), in particular from a wheel-hub pressure medium rotary union (21), to a vehicle rim (2) mounted on the wheel hub (1). The system (40) has a receiving part (41), which has a central region (55) with a central opening (44) and at least one extension region (43) projecting radially from the central region (55), at least in some regions. The receiving part (41) can be connected to the wheel hub (1) by means of the at least one radially projecting extension region (43), in a detachable way, and the control pressures and/or working pressures can be transmitted from the wheel-hub pressure medium supply (20, 21, 22) to the opening (44).
