Control apparatus and method of variable valve event and lift mechanism

In a variable valve event and lift mechanism that rotates a control shaft (16) by a motor to successively vary a valve event and a valve lift amount of engine valves (12), a VEL control unit integrally provided with an angle sensor (104) that detects a rotation angle of the control shaft, is disposed and a signal of a target rotation angle of the control shaft is output to the VEL control unit from an engine control unit, so that the VEL control unit feedback controls the motor.
