Disabled module 660 optionally disables AFM module 644 based on desired engine speed 664, thus forbids (proposing (present)) operating under AFM mode.Disabled module 660 can disable AFM module 644 when desired engine speed 664 is more than the second desired speed.Alternately, disabled module 660 can make AFM module 644 be activated when desired engine speed 664 is less than the second desired speed.Second desired speed can be equal to or different from that (being greater than) the first desired speed.The operating under AMF pattern can be made to be prohibited before one or more engine components are likely to be broken when engine speed 648 is more than the first desired speed equal to second desired speed of (or being more than) first desired speed.
Desired engine speed determines that module 668 determines desired engine speed 664.Desired engine speed determines that module 668 determines desired engine speed 664 based on GAP 608.It is only used as example, for given car speed, it is desirable to engine speed determines that module 668 can increase desired engine speed 664 when GAP 608 reduces (such as fourth speed is to third gear), and vice versa.
Desired engine speed determines that module 668 can be based further on vehicle rotating speed 672 to determine desired engine speed 664.It is only used as example, for the set-point of GAP 608, it is desirable to engine speed determines that module 668 can increase desired engine speed 664 when car speed 672 increases, and vice versa.Desired engine speed determines that module 668 can be for example with at least one in function and mapping (such as look-up table) to determine desired engine speed 664, and GAP 608 and car speed 672 are associated by least one in this function and mapping with desired engine speed 664.
Car speed determines that module 676 determines car speed 672.Being only used as example, car speed determines the wheel velocity that module 676 can be measured, the wheel velocity 680 such as measured with vehicle-wheel speed sensor 170 based on one or more, determines car speed 672.
With reference now to Fig. 7, it presents the flow chart describing to control the illustrative methods 700 of the operating under AFM mode.Control flow may begin at 704, and control flow determines whether to make electromotor 102 operate at AFM mode herein.If it is, control flow can continue to 708；If it is not, then control flow can terminate.Being only used as example, when engine speed 648 is less than the first desired speed, control flow can determine that and makes electromotor 102 operate at AFM mode.When engine speed 648 is more than the first desired speed, control flow can determine that and do not makes electromotor 102 operate at AFM mode.Being only used as example, the first desired speed can be about 3000
Rpm or additionally suitable rotational speed.Being only used as example, the first desired speed can be more than 2000 rpm.
At 708, control flow interrupts one or more cylinder to electromotor 102 supplies fuel, and the valve (inlet valve and exhaust valve) of one or more cylinder is maintained at make position.During AFM mode operates, valve is maintained at make position during running through each burn cycle by control flow, so that pumping loss minimizes.At 708, control flow additionally can disable spark to one or more cylinder.
At 712, control flow determines GAP 608 based on the GAP signal 452 using GAP sensor module 172 to produce.Control flow can show GAP 608 via DIC module 616.At 716, control flow determines desired engine speed 664 based on GAP 608.Control flow can be based further on car speed 672 to determine desired engine speed 664.Being only used as example, control flow can increase desired engine speed 664 when GAP 608 reduces and/or when car speed 672 increases.Control flow can reduce desired engine speed 664 when GAP 608 increases and/or when car speed 672 reduces.
At 720, control flow may determine that whether desired engine speed 664 is more than the second desired speed.If it is, control flow can forbid the operating under AFM mode at 724, and control flow can terminate.If it is not, then control flow can terminate.Second desired speed can be equal to or different from that the first desired speed.When AFM mode is disabled, valve rotation based on camshaft can return to open position rather than be maintained at make position.Fuel and spark are optionally provided to cylinder.Although control flow is shown as terminating, but Fig. 7 can be a diagram controlling circulation.
The extensively teaching of the disclosure can be implemented as various forms.Therefore, although the disclosure comprises particular example, but the true scope of the disclosure should not be so limited, because on the basis of those skilled in the art learn accompanying drawing, description and claims, other amendments will become obvious for a person skilled in the art.
