Abstract
An apparatus of generating a sound of a vehicle includes a motor configured to generate a torque of a rotational component and a torque of a vibration component, based on a target driving current, a controller configured to generate the target current by synthesizing a first signal for generating the torque of the rotational component and a second signal for generating the torque of the vibration component, and determine the target driving current for driving the motor based on the target current, and a sound output device to generate a target sound due to the torque of the vibration component.
Claims19
An apparatus of generating a sound of a vehicle, the apparatus comprising:
- a motor configured to generate a torque of a rotational component and a torque of a vibration component, according to a target driving current;
- a controller connected to the motor and configured to generate a target current by synthesizing a first signal for generating the torque of the rotational component and a second signal for generating the torque of the vibration component, and to determine the target driving current for driving the motor according to the target current;
- and
- a sound output device coupled to the motor and configured to generate a target sound by the torque of the vibration component.
A method of generating a sound of a vehicle, the method comprising:
- generating, by a controller, a target current by synthesizing a first signal for generating a torque of a rotational component and a second signal for generating a torque of a vibration component;
- determining, by the controller, a target driving current for driving a motor according to the target current;
- and
- generating, by a sound output device, a target sound according to the torque of the vibration component among the torque of the rotational component and the torque of the vibration component, which are generated from the motor according to the target driving current.
