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 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).

An engine device of this invention includes including a post-treatment device, provided in an exhaust passage of an engine, for purifying an exhaust gas from the engine. As the post-treatment device, a three-way catalyst is used. The engine device further includes a filter case including a filter body for catching deposits in the exhaust gas. The filter case is disposed, in a replaceable manner, upstream of the post-treatment device in the exhaust passage.

Methods and systems are provided for increase a rate at which a saddle fuel tank is depressurized responsive to a request for refueling. In one example, a method may include, responsive to the request for refueling, depressurizing a primary side of the saddle fuel tank to a secondary side of the saddle fuel tank, and commanding open a refueling lock coupled to the primary side to allow fuel to be delivered to the primary side when pressure in the primary side drops below a threshold pressure. In this way, the secondary fuel tank may be maintained at atmospheric pressure prior to the request for refueling, which may increase the rate of depressurization of the saddle fuel tank responsive to the request.

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 gaseous fuel supply system for an internal combustion engine may include a storage tank for storing liquefied gaseous fuel and supplying the fuel to the engine. The system may also include a liquid level sensor for measuring a level value of the liquefied gaseous fuel in the storage tank and a pressure sensor for measuring a pressure value of gaseous fuel in the fuel supply system. The system may further include a controller. The controller may be configured to: monitor a pressure signal of the pressure sensor indicating the pressure value and a tank level signal of the liquid level sensor indicating the level value; store the level value when the pressure value indicates the storage tank is empty; store the level value when the pressure value or the level value indicates the storage tank is full; and determine a calibrated level range based on the stored level values.

Disclosed is a vehicle control unit (10) comprising an electronic circuit, a circuit board (15), a housing (12) and at least one pressure sensor as a vehicle sensor (11), wherein the at least one vehicle sensor (11) is electrically connected to the electronic circuit for receiving measurement values. The vehicle sensor (11) is connected to the circuit board (15) via at least one press-fit contact (22). A vehicle comprising the vehicle control unit (10) is also disclosed.

A high pressure container system is equipped with an upstream side pressure sensor that measures an internal pressure of high pressure containers upstream of a pressure regulating valve, a plurality of downstream side pressure sensors that measure the pressure of the fluid downstream of the pressure regulating valve, and a control device. At a normal time of the downstream side pressure sensors, a control device monitors the internal pressure of the high pressure containers on the basis of the measured values of the downstream side pressure sensors, and at an abnormal time when any one of the downstream side pressure sensors is abnormal, the control device monitors the internal pressure of the high pressure containers on the basis of the measured values of the downstream side pressure sensors, and the measured value of the upstream side pressure sensor.
