The device includes at least one acceleration sensor provided to detect acceleration of a vehicle in at least one direction, a wheel speed sensor provided to detect a speed of a wheel, a lamp provided to emit light, a driving unit connected to the lamp to adjust a direction of light, and a controller configured to, when the vehicle is traveling, calculate a dynamic angle value of the vehicle with respect to a road surface while the vehicle is in acceleration or deceleration and calculate a first static angle value based on the dynamic angle value of the vehicle, and, when the vehicle is stopped, to calculate a second static angle value and a road slope value of a road on which the vehicle is positioned, and then control a direction of the light emitted forward of the lamp based on the first or the second static angle value.

A method is provided for operating a motor vehicle (100) having a headlight (1) with a projection module (2). The projection module (2) is moved into a projection position by a motor (3) to regulate a beam width of the headlight (1). The motor (3) is controlled to move the projection module (2) into the projection position and to reach a motor setpoint value. The motor setpoint value is stored in a non-volatile memory (4) of the headlight (1) and, when a voltage supply to the headlight (1) is activated following deactivation of the voltage supply, the projection module (2) is moved, starting from the stored motor setpoint value, into a leaving-home position so as to illuminate an environment adjacent to the motor vehicle (100). A headlight (1) and a motor vehicle (100) also are provided.

A headlight control apparatus sets a forward moving vehicle as a target vehicle, acquire a target longitudinal difference between a reference lateral line in a forward image and a target vehicle lateral line which defines a position of the target vehicle in a longitudinal direction in the forward image, acquire a target lateral difference between a reference longitudinal line in the forward image and a target vehicle longitudinal line which defines a position of the target vehicle in the lateral direction in the forward image, set a target lighting angle of the at least one headlight, depending on the target longitudinal and lateral differences, and adjust the lighting angle of at least one headlight to the target lighting angle.

A bank angle of a vehicle can be accurately calculated using yaw axis data and roll axis data, and based on the calculated bank angle, vehicle illumination optics can be controlled to maintain a pattern of distributed light from the illumination optics to be generally horizontal. The calculated bank angle may be zeroed when the yaw axis data equals zero. The improved pattern of distributed light from the illumination optics illuminates a more natural field of view for the vehicle driver during a bank.
