Value, so that corresponding variation occurs for the gas pressure in actuator tank body 22, so that the actual load that engine 10 generates
Difference with the demand load of engine 10 is less than the second preset value.
If being appreciated that, the difference of location information is 10 °, and electronic control unit 11 can preset the difference of location information
Value is the corresponding relationship that the difference of the aperture of 1 ° of corresponding vacuum control valve is 1.8%, according to the difference of location information and vacuum control
The corresponding relationship of the difference of the aperture of valve processed be calculated location information difference be 10 ° of corresponding vacuum control valves aperture
Difference is 18%, if the target aperture of vacuum control valve is 50%, then electronic control unit 11 will adjust vacuum control valve
Target aperture change 18%, if the location information be greater than target position information, then vacuum control valve target aperture will
18% can be reduced, the practical aperture of vacuum control valve is 32%, that is to say, that when the aperture of vacuum control valve is 32%, hair
The actual load of motivation 10 and the difference of demand load are less than the second preset value.
Further, in the present embodiment, the method also includes following steps:
Step S130, the electronic control unit 11 the actual load and the engine 10 demand load not
Match and when the difference of the actual load and the demand load is greater than or equal to first preset value, according to the actual negative
Lotus exports the second control instruction to the pressure controller 21, so that the pressure controller 21 is according to second control instruction
The gas pressure in the actuator tank body 22 is adjusted, so that actual load and the engine 10 that the engine 10 generates
Demand load matching.
