Signal Detection For Balancing Cylinders In A Motor Vehicle

摘要

The present disclosure teaches method for balancing cylinders in a motor vehicle including an engine which has at least two cylinders. The method may include: determining a cycle period of a cycle of the engine and a number of cycles of the engine, determining a cylinder value function for each cylinder of the engine for each cycle indicative of acceleration of a crankshaft of the engine caused by the corresponding cylinder, carrying out a signal analysis for each cylinder value function, detecting an amplitude for each signal, forming an amplitude mean value for each cylinder, detecting irregular running of the engine on the basis of the amplitude mean values, and compensating for the detected irregular running of the engine.

1. A method for balancing cylinders in a motor vehicle
including an engine which has at least two cylinders, the method comprising:
determining a cycle period of a cycle of the engine and a number of cycles of the engine,determining a cylinder value function for each cylinder of the engine for each cycle, wherein the cylinder value function is indicative of acceleration of a crankshaft of the engine, which is caused by the corresponding cylinder,carrying out a signal analysis for each determined cylinder value function,detecting an amplitude for each signal analysis which is carried out,forming an amplitude mean value for each cylinder on the basis of the detected amplitudes of the respective cylinder,detecting irregular running of the engine, on the basis of the amplitude mean values which are formed, andcompensating for the detected irregular running of the engine.
