摘要： Provided are a knocking determination device and a knocking control device for an internal combustion engine, with which a large amount of knocking can be detected quickly and with which knocking is easily determined. A knocking time window and a bandpass filter (BPF) are used (B1-B2) to extract a knocking frequency waveform signal from a knock sensor signal (Sg1), and integration is performed to obtain a first calculated value (B3). A reference time window and a BPF are used (B4-B5) to extract a reference frequency waveform signal from the knock sensor signal (Sg1), and integration is performed to obtain a second calculated value (B6). The average value of multiple instances of the second calculated value is obtained (B7), and the first calculated value is divided by the average value to obtain a signal-to-noise (S/N) ratio (B8). A multiplied value is obtained (B9) by multiplying the S/N ratio by a weighting coefficient, a moving average value for several of the multiplied values is obtained (10), and the moving average is used as a knocking indicator to determine knocking and to perform a control (B11-13).

摘要： The present invention relates to an ignition device for an idle stop & go system (ISG)-equipped vehicle using a liquefied petroleum gas (LPG) as a fuel. According to the present invention, an auxiliary LPG switch is separately installed. Said auxiliary LPG switch can sense the ON/OFF state of the LPG switch, drive a plurality of fuel cut-off solenoid valves, and be switched on/off together with the LPG switch. Therefore, the ON/OFF state of said LPG switch can be determined according to the second output voltage of the auxiliary LPG switch, and then ISG control can be implemented. After the fuel cut-off solenoid valves are driven by the relay's second voltage output by the auxiliary LPG switch, the fuel pressure in the fuel pipeline remains in the state before the idle stop to improve the starting performance of the engine at the time of restarting. In addition, in the case of an emergency, the LPG SW and the auxiliary LPG SW are simultaneously switched off, the fuel cut-off solenoid valves are quickly switched off and the fuel pump motor is also stopped so that the fuel supply can be cut off quickly and a secondary accident can be prevented in advance.

摘要： Variations in the air-fuel ratio among cylinders are specified as one cause of deterioration in exhaust emissions however the size of the variations in the air-fuel ratio among cylinders detected by the catalyst upstream sensor does not always match the margin of deterioration in exhaust emissions. The objective of the present invention is to detect the deterioration in the exhaust emissions caused due to variations in the air-fuel ratio among cylinders. Deterioration in exhaust emissions due to variations in the air-fuel ratio among engine cylinders is detected based on a means to calculate a specified frequency component A of the catalyst upstream sensor signal; a means to calculate a specified frequency component B of the catalyst downstream sensor signal; and the frequency component A and the frequency component B.

摘要： The invention relates to a method of controlling a vehicle powertrain including determining that a performance feature associated with the powertrain is outside of a desired performance range. A plurality of operation parameters that are associated with the powertrain are identified that have a relationship to the performance feature. An adjustment is automatically made to at least one of the identified operation parameters to thereby bring the performance feature closer to the desired performance range. Preferably, the relationship comprises a mathematical model that corresponds to how the operation parameters influence whether the performance feature is within the desired performance range, the method further comprising identifying an actuator failure associated with the powertrain; determining at least one of the operation parameters corresponding to the actuator failure; determining a value of the corresponding operation parameter that is indicative of the actuator failure; and using the determined value as a fixed value for the corresponding operation parameter in the mathematical model.
