Abstract
A vehicle includes a driving motor; a driver electrically connected to the driving motor; and a controller electrically connected to the driver; wherein the controller is configured to control the driver to supply a driving current in which a first driving current for controlling a driving speed of the vehicle and a second driving current for generating vibration in the vehicle are overlapped, to the driving motor.
Claims20
A vehicle, comprising:
- a driving motor for driving the vehicle;
- a driver electrically connected to the driving motor;
- and
- a controller electrically connected to the driver;
- wherein the controller is configured to control the driver to supply a driving current to the driving motor,
- wherein the driving current includes a first driving current and a second driving current,
- wherein the driving motor is configured to receive the first driving current and control a driving speed of the vehicle,
- wherein the driving motor is configured to receive the second driving current and generate vibration in the vehicle, and
- wherein the controller is configured to determine a d-axis current value calculated based on a three-phase driving current of the driving motor and an electrical angle of a rotor provided in the driving motor, and control the vibration of the vehicle using the determined d-axis current value.

A method for controlling a vehicle including a driving motor, the method comprising:
- obtaining driving information of the vehicle including the driving motor for driving the vehicle;
- obtaining environmental information around the vehicle;
- and
- supplying, by a controller, a driving current to the driving motor,
- wherein the supplying the driving current to the driving motor includes:
- supplying, by the controller, a first driving current included in the driving current to the driving motor,
- receiving, by the driving motor, the first driving current and controlling a driving speed of the vehicle, and
- supplying, by the controller, a second driving current included in the driving current to the driving motor, and
- receiving, by the driving motor, the second driving current and generating vibration in the vehicle,
- wherein the supplying of the second driving current to the driving motor includes:
- determining, as the second current value, a d-axis current value calculated based on a three-phase driving current of the driving motor and an electrical angle of a rotor provided in the driving motor, and
- supplying a control signal for the vibration of the vehicle using the determined d-axis current value to the driving motor.
