A vehicular lane centering system is enabled responsive to speed of the vehicle exceeding a threshold speed and includes a camera and a processor. Based on processing of captured image data, the system determines position of a left lane delimiter and a right lane delimiter on the road. The system establishes a left safe zone delimiter based on the determined position of the left lane delimiter and a right safe zone delimiter based on the determined position of the right lane delimiter. With the system enabled, the system takes corrective action responsive to the vehicular lane centering system determining that the vehicle is at risk of unintentionally crossing the left safe zone delimiter or the right safe zone delimiter. When the system does not determine position of the left lane delimiter or the right lane delimiter for a first period of time, corrective action taken by the system is reduced.

Vehicular lane centering system

A lane centering system for use in a vehicle driving in a lane on a road includes a camera and a controller. Based on processing by a processor of image data captured by the camera, the controller determines position of a left lane delimiter on the road on a left side of the vehicle and position of a right lane delimiter on the road on a right side of the vehicle. The controller is operable to determine a target path for the vehicle based on processing of image data captured by the camera. The determined target path maintains the longitudinal centerline of the vehicle centered between the left lane delimiter and the right lane delimiter. The lane centering system may be enabled responsive to the vehicle speed exceeding a threshold speed, and may be disabled during a braking event of a collision mitigation system of the vehicle.

A lane centering system for use in a vehicle driving in a lane on a road includes a camera and a controller. Based on processing by a processor of image data captured by the camera, the controller determines the position of a left lane delimiter on the road on a left side of the vehicle and the position of a right lane delimiter on the road on a right side of the vehicle. The controller is operable to control a steering system of the vehicle that is configured to steer the vehicle. The controller is operable to determine a target path for the vehicle based on processing by the processor of image data captured by the camera. The determined target path maintains the longitudinal centerline of the vehicle centered between the left lane delimiter and the right lane delimiter.

Lane keeping system and lane centering system

A lane centering system for use in a vehicle driving in a lane on a road includes a lane delimiter detection device having a camera with a field of view that encompasses the road ahead of the vehicle. Based on processing of captured image data, a controller determines the positions of left and right lane delimiters on the road. The controller is operable to establish a target path for the vehicle that maintains the longitudinal centerline of the vehicle generally centered between the left lane delimiter and the right lane delimiter. The controller is automatically activated to control steering the vehicle along the target path when the speed of the vehicle is at or above a first speed level. When having activated control of steering, the controller automatically deactivates control of steering when the speed of the vehicle falls to at or below a second speed level.

A lane keeping system for a vehicle sets a safe zone in which the driver can drive the vehicle. If the system determines that the driver is at risk of leaving the safe zone, the system takes a corrective action, such as notifying the driver or applying a steering correction to the vehicle. The system adjusts the width of the safe zone depending on the driver's capability to stay within the safe zone. A lane centering system may be capable of autonomously steering the vehicle to remain within a lane. The lane centering system may include a controller that determines a target path for the vehicle depending on certain parameters. The controller may model each of the lane delimiters in a simplified form. This facilitates the determination of one of the target paths (the centerline of the lane). The simplified form may be a 3rd order polynomial equation.

The present invention relates to a navigation unit and base station used for determining location. A plurality of base stations are initialized to determine their location relative to each other. At the navigation unit, the time of arrival of at least one signal from each of the plurality of base stations is measured. From this, the location of the navigation unit relative to the plurality of base stations may be directly calculated using a closed solution. In one embodiment, a time of arrival technique is used and in another embodiment a time difference of arrival technique is used. Preferably an ultra-wide band frequency is utilized.

Target and base station for a navigation system

The present invention includes an artificial horizon device including a sensor unit with a movable platform, at least one actuator linked to the platform, and one or more sensors located on the platform for sensing the position orientation of the platform relative to an external mass or the motion of the platform. The horizon device also includes a processing unit signally connected to the sensors and the at least one actuator. The processing unit is adapted to receive signals from the sensors and send signals to the actuators to move the platform to a horizontal orientation. The horizon device also includes either a display unit comprising an indicator of a horizon line which substantially corresponds to the horizontal orientation of the platform or a secondary device.

A guitar pick having a planar and generally triangular main body with three sides. Two sides of the main body join in a rounded nose protruding outwardly from one side. A wing extends outwardly from the top of the main body so that at least a portion of the wing lies in a plane oblique to a plane of the main body. The wing may be curvilinear in shape or include plural planar sections.
