摘要： Various embodiments include a method for controlling a motor vehicle having an internal combustion engine with a crankshaft and a drivetrain separable from the internal combustion engine using a releasable clutch comprising: propelling the vehicle in a first operating state in a predetermined range around a speed while the internal combustion engine is off and is separated from the drivetrain by the releasable clutch; sensing a braking operation while in the first operating state; predicting whether a power demand is expected within a predetermined time interval; and, if the power demand is expected, setting the crankshaft of the internal combustion engine in rotation, or increasing a rotational speed of the crankshaft in preparation for an engine restart.

摘要： A control system for a vehicle is provided, which includes a driving force source configured to generate torque for driving drive wheels, a steering angle related value sensor configured to detect a steering angle related value of a steering device, and a controller configured to control the torque to control the vehicle attitude based on the steering angle related value. The controller acquires a current traveling mode defining a response of acceleration or deceleration of the vehicle to an accelerator pedal operation. Based on the steering angle related value, when determined that a turning operation of the steering device in one direction is performed, the controller performs a torque decreasing control to add deceleration to the vehicle. When the acquired traveling mode is a high response traveling mode, the controller increases a reduction amount of the torque in the torque decreasing control more than in a low response traveling mode.

摘要： An internal combustion engine ignition device includes an ignition coil, an ignition plug, a main ignition circuit, and an energy input circuit. A first switching element of the main ignition circuit performs energization and interruption of energization to a first coil part of a primary coil to generate an induced electromotive force using a DC voltage. A second switching element of the energy input circuit performs energization and interruption of energization to a second coil part of the primary coil to keep a discharge current in a secondary coil within an intended range directly using the DC voltage, after the induced electromotive force has been generated. A soft-off circuit of the energy input circuit slows a turn-off speed of the second switching element. The energy input circuit is configured to, when decreasing a signal voltage added to a gate of the second switching element, execute a first decreasing stage of decreasing the signal voltage until it reaches the vicinity of a gate-source threshold voltage and a second decreasing stage of gradually decreasing the signal voltage in the vicinity of the threshold voltage.

摘要： Methods and systems are provided for multiplexing ignition signals in an engine system based on engine operating conditions, each cylinder of the engine system including a main chamber spark plug and a pre-chamber system. In one example, a method may include multiplexing spark signals to a first spark plug and a second spark plug, the first spark plug coupled to a pre-chamber of a first cylinder and the second spark plug coupled to a main chamber of a second cylinder. In this way, one ignition coil may be used to actuate two different spark plugs coupled to separate cylinders.

摘要： A method of controlling an engine is provided, the method including the steps of injecting main fuel by a fuel injector during an intake stroke or a compression stroke, providing a mixture gas containing fuel and air inside a cylinder, applying by an ignition device a high voltage between electrodes of a spark plug at a timing when the mixture gas is not ignited, detecting a parameter related to a current value of an electric-discharge channel generated between the electrodes, determining whether the detected parameter is within a range between a first threshold and a second threshold to determine a flowing state of a vortex inside the cylinder, injecting supplemental fuel by the fuel injector after the main fuel injection when the parameter is determined to be outside the range, and igniting the mixture gas by the ignition device using the spark plug after the supplemental fuel injection.

摘要： A power control method/process of an internal combustion engine employing a selective ignition delay, in which the process chooses, in real time, just before the ignition, whether the next cylinder should have its power reduced or not, in such a way that this choice at high speed, individualized by cylinder, guarantees a higher resolution in the power control, where the process has the following steps: vaporized air and fuel enters the combustion chamber of the cylinder; a piston compresses the air and fuel increasing their pressure; the ignition spark does not occur, keeping the gases in the combustion chamber unchanged; the inertia of the engine causes the piston to move, where the ignition spark occurs shortly thereafter, with reduced work generation; air and fuel still expanding are expelled through the exhaust valve.
