Abstract:
1. An active eco pedal apparatus comprising: a pedal which is hinged to a vehicle body to be pushed by a driver, the pedal being returned to an initial position by a resilient restoring force when the pushing of the driver is released; an actuator including a voice coil motor (VCM) having a pair of coils which generate an electric field by a current supplied from an exterior, and a pair of magnets each having an N-pole and an S-pole interacting with an electric field generated from the pair of coils, in which two different basic moving forces Fa and Fb are created in the same direction by an electromagnetic field generated by action of the N-pole and the S-pole and the electric field, one repulsive force Fc is generated by the same polarity in the electromagnetic field generated by the action of the N-pole and the S-pole and the electric field and the electric field generated when the current flows through the pair of coils in opposite directions, and the one repulsive force Fc is added to the basic moving forces Fa and Fb to increase a magnitude of the basic moving forces Fa and Fb; and a holder which applies a resilient force to the actuator to restrain unexpected movement of the actuator when an eco mode is not activated, wherein the pedal is provided with an adjustor, and the adjustor is moved toward or away from a driver using power of a motor to adjust an interval of the pedal to the driver; and a rotary driving cable is connected to the motor, and adjusts the interval of a brake pedal using the power of the motor, as well as the pedal.
