Abstract
A lamp system and method are provided. The system includes a swivel control section which is configured to control an irradiating direction of a lamp so as to follow a steering angle of a steering wheel of a vehicle, a filter section which is configured to change a following response of a change of the irradiating direction with respect to a change of the steering angle, and a filter control section which is configured to control the filter section to decrease the following response when an angular acceleration of the steering angle is greater than or equal to a reference value.
Claims8
A lamp system comprising:
- a swivel control section which is configured to control an irradiating direction of a lamp so as to follow a steering angle of a steering wheel of a vehicle;
- a filter section which is configured to change a following response of a change of the irradiating direction with respect to a change of the steering angle;
- and
- a filter control section which is configured to control the filter section to decrease the following response when an angular acceleration of the steering angle is greater than or equal to a reference value.
A method of controlling a deflection of an irradiating direction of a lamp, the method comprising:
- detecting a steering angle of a steering wheel;
- calculating an angular acceleration of the detected steering angle;
- comparing the calculated angular acceleration with a reference value;
- and
- decreasing a following response of the deflection of the irradiating direction with respect to the steering angle if the calculated angular acceleration is greater than or equal to the reference value.
