Abstract
A valve timing control apparatus includes a driving-side rotating member, a driven-side rotating member, a fluid pressure chamber defined by the driving-side rotating member and the driven-side rotating member and divided into a retarded angle chamber and an advanced angle chamber by a parting portion, an angle detecting portion detecting a relative angle of the driven-side rotating member relative to the driving-side rotating member, a fluid control mechanism controlling a supply and a discharge of an operation fluid to and from the fluid pressure chamber, an acceleration operation quantity detecting mechanism detecting an acceleration operation quantity, and a control portion setting either a normal drive mode or an acceleration drive mode as a control mode relative to the fluid control mechanism based on the acceleration operation quantity, and controlling the fluid control mechanism so that the relative angle corresponds to a target angle determined based on the set control mode.
