A vehicular collision mitigation method includes disposing at a vehicle a plurality of cameras, at least two non-camera sensors, and a control that processes data captured by the cameras and non-camera sensors. When the equipped vehicle is traveling forward, and via processing at the control of provided data captured by the forward viewing camera and the at least two non-camera sensors, it is determined if the vehicle is approaching a pedestrian or other vehicle forward of the vehicle. Responsive to such determination, braking by an automatic emergency braking system is controlled to mitigate collision with the pedestrian or other vehicle. Responsive to determination that a following vehicle is following the vehicle within a threshold distance from the vehicle and is approaching the vehicle above a threshold rate of approach, braking by the automatic emergency braking system is adjusted to mitigate collision at the rear of the vehicle by the following vehicle.

In a control system for an internal combustion engine which stops the rotation of an internal combustion engine by applying a counter torque thereto, the generation of noise or vibration accompanying the stop of rotation of the internal combustion engine is suppressed as much as possible. In the control system provided with a controller being adapted to stop the rotation of the internal combustion engine by carrying out forced stop processing in which the counter torque is inputted, in cases where the forced stop processing is carried out after the completion of the execution of specific motoring processing, the controller makes the counter torque at a certain timing before the counter torque becomes a predetermined torque after the start of the execution of the forced stop processing smaller than in the case where the forced stop processing is carried out without carrying out the specific motoring processing.

Methods and systems are provided for operating an electric motor to drive either a transmission fluid pump or a direct injection fuel pump. In one example, a method may include operating an electric motor to drive a direct injection fuel pump to supply fuel to a direct injection fuel rail while an engine of a start/stop vehicle is on, and operating the electric motor to drive an auxiliary transmission fluid pump to circulate transmission fluid to a transmission rotationally coupled to the engine while the engine is off during an auto-stop. In this way, the direct injection fuel pump may be electrically driven without increasing vehicle costs through adding an additional electric motor.

A turbocharger system (1) of a combustion engine (4) comprises a turbocharger turbine (5) operable by exhaust gases, a valve (7) configured to control gas flow of pressurized gas from a pressurized gas reservoir (6) to the turbocharger turbine (5), and a sensor (8). Turbocharger system operation comprises injecting a test pulse of pressurized gas from the pressurized gas reservoir (6) to drive the turbocharger turbine (5) by means of controlling the valve (7), detecting an impact of injected pressurized gas on the turbocharger turbine (5) by means of the sensor (8), collecting data from the sensor (8), and diagnosing the turbocharger system (1) by evaluating an operational response of the turbocharger turbine (5) as a result of the injected test pulse of pressurized gas, based on the collected data.

An internal combustion engine management system includes: a plurality of internal combustion engine units of which each includes an internal combustion engine, a first communicator configured to communicate with a server device, and a communication controller configured to transmit at least estimation information out of the estimation information which is used to estimate an environment in which the internal combustion engine is placed and information of a control map which is used to control the internal combustion engine to the server device using the first communicator; and the server device that includes a second communicator configured to communicate with the first communicator, and a processor configured to extract a second internal combustion engine unit having transmitted estimation information which is similar to the estimation information received from a first internal combustion engine unit out of the plurality of internal combustion engine units from the plurality of internal combustion engine units and to transmit the information of a control map received from the second internal combustion engine unit to the first internal combustion engine unit using the second communicator.

A Purge Control Solenoid Valve (PCSV) control method for preventing malfunction may include: starting-up by a starting motor a crankshaft of an engine, and opening PCSV by a duty-control, wherein in the starting-up step, the PCSV is opened to eliminate foreign substances stained on the PCSV.

A method for determining a corrected air mass flow value in an engine having an air mass meter in its intake. The method includes determining a cold start condition of the engine at a first time when there is no air mass flow in the intake tract, producing a reference signal by the air mass meter at the first time, and determining an air mass flow offset from the reference signal, producing a measurement signal by the air mass meter at a second time, which is not equal to the first time, which is in an operating period of the engine, determining an air mass flow value from the measurement signal, and determining a corrected air mass flow value from the air mass flow offset and the air mass flow value.

Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, the engine system may be installed in a hybrid vehicle, and, in response to a request to restart the engine while the vehicle is being propelled via motor torque only, the engine may be rotated unfueled via the motor torque at less than cranking speed while at least partially opening a valve disposed in a passage coupled between the first exhaust manifold and the intake passage. In another example, in response to the request to restart the engine, all exhaust valves of a second set of exhaust valves coupled to the second exhaust manifold may be deactivated.

A centrifugal separator includes a housing and a rotary vessel having an axis and being attached to the housing for rotation relative to the housing about the axis. Either: a) the rotary vessel has one or more magnetisable regions and the housing has one or more electromagnetic windings; or b) the rotary vessel has one or more electromagnetic windings and the housing has one or more magnetisable regions. The electromagnetic windings are selectively energisable to create a magnetic field to cause rotation of the rotary vessel.

Provided is a marine engine, including: an air controller configured to supply compressed air to a combustion chamber in an upstroke of a piston after a crash astern signal is output; a fuel controller configured to stop supply of fuel to the combustion chamber when the crash astern signal is output, and to resume the supply of the fuel after a backward rotation of a crankshaft; and a compression ratio controller configured to move a top dead center position of the piston toward an opposite side of a bottom dead center position of the piston when the crash astern signal is output, and the top dead center position of the piston is on the bottom dead center position side with respect to a predetermined position set in advance.
