  • Patent number: 10458356
    Abstract: A vehicle control apparatus performs an in-excess determination control by monitoring a drive power in-excess indicator at a time when a temporary in-excess state occurs which indicates that a drive power excess amount exceeds a predetermined value. As such, when a vehicle-dynamic safety parameter fulfills a prescribed condition, the vehicle control apparatus lowers an indicator threshold for determining an excess drive power continuation time from an original value to a lowered value. As a result, the excess drive power continuation time is determined as exceeding the indicator threshold, which indicates that a drive power of a vehicle is in excess, and a fail-safe instruction signal output is brought forward from an original timing to an earlier timing. Therefore, when a degree of dangerousness of a vehicle behavior is estimated to be relatively high, a fail-safe action is promptly taken.

  • Patent number: 10190519
    Abstract: The invention relates to a control device for an internal combustion engine that includes a turbocharger, and an actuator that changes a turbocharging pressure by regulating exhaust energy for use in drive of the turbocharger. When a target torque is increased during execution of a lean burn operation, the control device switches an operation mode of the internal combustion engine from the lean burn operation to a stoichiometric operation. When the operation mode switching is performed in a turbocharging state, the control device determines whether a target torque is within a range of a torque realizable under the lean air-fuel ratio. When the target torque is within the range, the control device operates the actuator so as to keep the turbocharging pressure at a magnitude equal to or larger than a magnitude at a time point at which the operation mode is switched.

  • Patent number: 10094313
    Abstract: A variety of methods and arrangements are described for controlling transitions between firing fractions during skip fire or other dynamic firing level modulation operation of an engine. In general, actuator first transition strategies are described in which an actuator position (e.g., cam phase, TCC slip, etc.) is changed to, or close to a target position before a corresponding firing fraction change is implemented. When the actuator change associated with a desired firing fraction change is relatively large, the firing fraction change is divided into a series of two or more firing fraction change steps. A number of intermediate target selection schemes are described as well.

  • Patent number: 9982611
    Abstract: A variety of methods and arrangements for improving the fuel efficiency of internal combustion engines based on skip fire operation of the engine are described. In one aspect the skip fire decisions are made on a working cycle by working cycle basis. During selected skipped working cycles, the corresponding cylinders are deactivated such that air is not pumped through the cylinder during the selected skipped working cycles. In some implementations, the cylinders are deactivated by holding associated intake and exhaust valves closed such that an air charge is not present in the working chamber during the selected skipped working cycles.

  • Patent number: 9944280
    Abstract: A vehicle control system includes: multiple control units which controls operation of a vehicle including an internal combustion engine, a first electric motor connected to the internal combustion engine, and a second electric motor; and a network connected to the control units such that the control units perform communication with each other. The control units include a first control unit which controls the internal combustion engine, a second control unit which controls the first motor, and a third control unit which controls the second motor, and each detect abnormality in communication via the network among the control units. Upon detection of abnormality in communication between the second control unit and the other control units via the network, the first control unit stops operation of the internal combustion engine, and the third control unit performs control such that the second motor outputs power for the vehicle to travel.

  • Patent number: 9926826
    Abstract: An internal combustion engine is provided with a hydrocarbon feed valve arranged in an engine exhaust passage. When injection control for injecting hydrocarbons from the hydrocarbon feed valve for exhaust treatment is stopped, to prevent the hydrocarbon feed valve from clogging, hydrocarbons for preventing clogging are injected from the hydrocarbon feed valve when the engine is not discharging soot, that is, when the feed of fuel to the inside of the combustion chamber is stopped and, after hydrocarbons for preventing clogging are injected once, the injection of hydrocarbons for preventing clogging from the hydrocarbon feed valve is stopped until injection control for exhaust treatment is started.

  • Patent number: 9926868
    Abstract: A variety of methods and arrangements are described for controlling transitions between firing fractions during skip fire and potentially variable displacement operation of an engine. In general, cam first transition strategies are described in which the cam phase is changed to, or close to a target cam phase before a corresponding firing fraction change is implemented. When the cam phase change associated with a desired firing fraction change is relatively large, the firing fraction change is divided into a series of two or more firing fraction change steps—with each step using a cam first transition approach. A number of intermediate target selection schemes are described as well.
