摘要： An active vision system includes an image capture device for capturing images in a region exterior of a vehicle and a headlamp control unit for controlling a vehicle headlamp beam for illuminating an environment exterior of a vehicle. The headlamp control unit is configured to selectively illuminate between making a path of travel of a road visible to a driver of the vehicle and making the region exterior of the vehicle visible for capturing images by the image capture device. The headlamp control unit utilizes a duty cycle for controlling a first cycle time that the headlamp beam illuminates the path of travel for making the road visible to the driver and for controlling a second cycle time that the headlamp beam makes the captured region visible for capturing images by the image capture device.

摘要： A system and method for controlling a vehicle sun visor that uses commonly existing onboard sensors and systems to provide all necessary inputs. The method uses GPS and solar almanac data to determine the location of the sun relative to the vehicle, driver side view mirror angle data to determine the position of the driver's eyes within the vehicle, and an existing outside light metering device to determine whether the sun is actually shining on the vehicle, and uses this information to calculate the optimum position of the sun visor. If a forward-looking camera is available on the vehicle, camera images can be used to improve the estimate of the sun position relative to the vehicle.

摘要： A system and method for automatically calibrating the aiming direction of a camera onboard a vehicle. The method uses GPS and solar almanac data to estimate the location of the sun relative to the vehicle, and compares this to the solar position in an image from the camera. The comparison is performed with an ongoing recursive calculation which yields an improved estimate of the sun position relative to the vehicle, while simultaneously calibrating the aiming direction of the camera. The aiming calibration data is used to improve the accuracy of the camera's images as used for all of the camera's other functions.

摘要： A linear actuator associated with an actuator system for a device includes a wire cable fabricated from an active material. The linear actuator couples to the device and to the moveable element. The active material induces strain in the linear actuator in response to an activation signal. The linear actuator translates the moveable element relative to the device in response to the induced strain. An activation controller electrically connects to the linear actuator and generates the activation signal. A position feedback sensor monitors a position of the moveable element.
