Claims

[Scope of Claim for Utility Model Registration] (1) A vehicle speed sensor that detects vehicle speed, a steering angle sensor that detects the steering angle of a steering wheel, and the vehicle speed detected by the vehicle speed sensor and the steering angle detected by the steering angle sensor. The vehicle is characterized by comprising a control device that determines the angle of the headlight according to the angle and outputs a drive signal according to the angle, and an actuator that rotates the headlight rotatably attached to the vehicle body in accordance with the drive signal. Steering-linked headlight device. (2) The control device includes a prediction calculation means for predicting the traveling direction of the automobile according to the vehicle speed detected by the vehicle speed sensor and the steering angle detected by the steering angle sensor, and a traveling direction output from the prediction calculation means. 2. The steering-linked headlight device according to claim 1, further comprising: angle calculation means for determining the angle of the headlight by the angle calculation means; and drive signal formation means for forming a drive signal based on the output from the angle calculation means. (3) The control device sets a control prohibited area according to the vehicle speed detected by the vehicle speed sensor and the steering angle detected by the steering angle sensor, and determines whether a value based on both detected values exceeds the control prohibited area. 2. The steering-linked headlight device according to claim 1, wherein the headlight is controlled to be driven only when the steering wheel is turned. (4) The steering-linked headlight device according to claim 1, wherein the control device is configured to independently rotate only the headlight in the direction of travel of the vehicle determined by the steering angle detected by the steering angle sensor.
