摘要
A system and method for determining an estimation of actual cam phase angle of increased accuracy are based on an observed cam phase angle derived from a cam phase sensor and a predicted cam phase angle derived from a desired or commanded cam phase angle. The estimated cam phase angle is used in the electronic control unit in computing desired settings for engine variables which depend on cam phase angle.
