A Controller And Method To Correct A Combustionparameter During Transient Condition Of Anengine

Claims:1. A controller (110) to correct a combustion parameter during transient condition of an engine (116), said controller (110) configured to receive an input signal (202) for at least one input parameter, determine a transient condition based on a rate 5 of change of said input parameter, referred to as a primary signal (112), characterized by, said controller (110) adapted to generate a secondary signal (114) based on said primary signal (112), and 10 correct said combustion parameter based on said secondary signal (114). 2. The controller (110) as claimed in claim 1, wherein said at least one input parameter is selected from a group comprising a throttle position and an 15 engine speed. 3. The controller (110) as claimed in claim 1, wherein to generate said secondary signal (114), said controller (110) adapted to create said secondary signal (114), and values of which is set to 20 follow said primary signal (112) until a maximum value (204) of said primary signal (112) is reached during said transient condition, retain value of said secondary signal (114) for a configurable period of time, and filter value of said secondary signal (114) back to value of said 25 primary signal (112). 4. The controller (110) as claimed in claim 3, wherein said configurable period of time is calculated based on at least one of said input parameter and an engine temperature. 5. The controller (110) as claimed in claim 1, wherein combustion parameter is at least one selected from a group comprising an ignition angle, ignition time and injection quantity. 6. A method for correcting a combustion parameter during transient 5 condition of an engine (116), said method comprising the steps of receiving an input signal (202) for at least one input parameter, determining a transient condition based on a rate of change of said input parameter, referred to as primary signal (112), characterized 10 by, generating a secondary signal (114) based on said primary signal (112), and correcting said combustion parameter based on said secondary signal (114). 7. The method as claimed in claim 6, wherein said at least one input parameter is selected from a group comprising a throttle position and an engine speed. 8. The method as claimed in claim 6, wherein generating said secondary signal 20 (114) comprises creating said secondary signal (114), and following said primary signal (112) until a maximum value (204) of said primary signal (112) is reached during said transient condition, retaining said value of said secondary signal (114) for a configurable 25 period of time, and filtering value of said secondary signal (114) back to value of said primary signal (112). 9. The method as claimed in claim 8, wherein said configurable period of time 30 is calculated based on at least one of said input parameter and an engine temperature. 10. The method as claimed in claim 6, wherein combustion parameter is at least one selected from a group comprising an ignition angle, ignition time and injection quantity. , Description:The controller 110 configured to receive an input signal 202 for at least one input parameter, determine a transient condition based on a rate of change of the input parameter. A signal corresponding to the rate of change of the input parameter is referred to as a primary signal 112. The controller 110 characterized by, is adapted to generate a secondary signal 114 based on the primary signal 112, and correct the combustion parameter based on the secondary signal 114. The controller 110 is also referred to as Engine Management System (EMS) of the vehicle 100. The combustion parameter is at least one selected from a group comprising an ignition angle, ignition time and injection quantity. The controller 110 and the method improves the drivability of the vehicle. Figure 1
