A positive crankcase ventilation gas diversion system comprises a positive crankcase ventilation gas diversion line to divert oil laden positive crankcase ventilation gases from the air intake manifold of an internal combustion engine. A positive crankcase ventilation gas diversion interconnect directs oil laden positive crankcase ventilation gases into an oil-vapor diffuser which at least partially separates crankcase oils from the oil laden positive crankcase ventilation gases. A pressure sensor measures a vapor pressure in a headspace of a fuel tank, and a fuel tank vent valve is operative with a fuel tank vent line. A controller actuates the fuel tank vent valve into an open position and discharges fuel enriched vapor to the air intake manifold of the internal combustion engine, thereby maintaining the vapor pressure in the headspace of the fuel tank within a predetermined pressure range.

Methods and systems are provided for conducting an engine off natural vacuum test in a vehicle in order to indicate the presence or absence of undesired evaporative emissions. In one example, a vehicle fuel system and evaporative emissions system are sealed from atmosphere, and responsive to a pressure increase below an expected threshold, the fuel system and evaporative emissions system are actively pressurized via circulating hot engine coolant to a heater core and blowing hot air through the vehicle cabin to the fuel system via a three way ventilation valve in the rear of the vehicle. In this way, false failures of EONV test procedures due to environmental factors and vehicle operator drive habits may be reduced, and unnecessary engine service may be avoided.

A brake system for motor vehicles may include an actuation device (e.g., brake pedal), a travel simulator to generate a feedback force on the actuation device, a first piston-cylinder unit having at least one piston that separates two working chambers that are connected via at least one hydraulic line to at least one wheel brake of a brake circuit, a control device and a pressure supply unit driven by an electric motor. At least one wheel brake may be assigned to each brake circuit, and each wheel brake may be connected to its associated hydraulic connecting line via a controllable switching valve. An outlet valve may be assigned to a single wheel brake or to a single wheel brake of each brake circuit in a hydraulic connection between the wheel brake and a pressure medium storage container, without any further valve disposed as such.

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.

The present invention provides improved, real time sensing of pressure supplied to the hydraulic operator of a clutch for a motor vehicle driveline power take off. A proportional sensor in the hydraulic line to the power take off clutch actuator provides a data signal in real time of the actual pressure applied to the clutch actuator. This signal is provided to the power take off control module (PCM) and/or to the transmission control module (TCM). The power take off control module, having instantaneous data regarding the pressure applied to the hydraulic operator achieves two important operating functions: monitoring and feedback.

A steering input apparatus for a vehicle includes a grip position sensor configured to sense a grip position on a rim of a steering wheel of the vehicle. The steering input apparatus also includes at least one processor configured to, based on a determination that the grip position on the rim of the steering wheel sensed through the grip position sensor is improper for a driving situation of the vehicle, perform a control operation to output grip guide information for the rim of the steering wheel.

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.

A system for a vehicle comprises a load sensor configured to sense a load on the vehicle. The vehicle further includes a load indicator where the load indicator is disposed proximate the vehicle such that the load indicator generates an output in response to the load sensed by the load sensor.

An automotive wearable electronic device arrangement for a motor vehicle includes an indicator device indicating a state of an operating parameter of the vehicle. A wireless communication device is communicatively coupled to the indicator device and detects that a driver is wearing a wearable electronic device. The detecting includes receiving a signal from the wearable electronic device. The wireless communication device transmits a signal to the wearable electronic device instructing the wearable electronic device to cease issuing notifications to the driver. The transmitting is dependent upon a state of an operating parameter indicated by the indicator device.

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.
