Combustion engine angular position or velocity determination system in which incremental encoder wheel markings are compensated based on comparison of their positions and corresponding pressure measurements with ideal values
Combustion engine angular position or velocity determination system in which incremental encoder wheel markings are compensated based on comparison of their positions and corresponding pressure measurements with ideal values
Method for compensation correcting of the position of angle markers on the incremental wheel (2) of an angular position or velocity sensor (1-4) for a combustion engine is based on measurement of actual angle marker positions and measurement of cylinder pressures during the combustion cycle. Matching pressure and angle positions are stored in a look-up table and the angle values are compensated based on comparison with ideal angle and pressure values. The invention also relates to a corresponding system.
