VCT actuator end of stroke control method

In a VCT system (10a), a method uses a controller to automatically determine a state of a phaser (42) based on an identifier (50). The identifier (50) identifies a filtered signal (48) of the crank shaft (24) and cam shaft (22)and uses the same to identify the phaser state. A reset signal (52)is generated by the identifier (50) to reset the VCT system (10a), specifically to reset a control law (18) whereby the unnecessary information retained by the VCT system (10a) is cleared. Therefore, the controller is able to promptly and accurately determine (70) the phaser position and state.
