Abstract: A vision system for a vehicle includes a camera disposed at or proximate to an in-cabin portion of a windshield of the vehicle. The camera has a forward field of view to the exterior of the vehicle through the windshield of the vehicle. The camera is operable to capture image data. A control includes an image processor that is operable to process captured image data to determine lane delimiters present in the field of view of the camera. The control connects to a vehicle communication bus of the vehicle and receives vehicle data via the vehicle communication bus. Responsive at least in part to processing of captured image data by the image processor and to vehicle data received via the vehicle communication bus, the control determines a yaw rate. The control provides the determined yaw rate to a driver assistance system of the vehicle.

Abstract: A control system or method for a vehicle references a camera and sensors to determine when an offset of a yaw rate sensor may be updated. The sensors may include a longitudinal accelerometer, a transmission sensor, a vehicle speed sensor, and a steering angle sensor. The offset of the yaw rate sensor may be updated when the vehicle is determined to be stationary by referencing at least a derivative of an acceleration from the longitudinal accelerometer. The offset of the yaw rate sensor may be updated when the vehicle is determined to be moving straight by referencing at least image data captured by the camera. Lane delimiters may be detected in the captured image data and evaluated to determine a level of confidence in the straight movement. When the offset of the yaw rate sensor is to be updated, a ratio of new offset to old offset may be used.

Abstract: A vehicular vision system includes a camera disposed at an in-cabin side of a windshield of a vehicle. Responsive at least in part to processing of captured image data, the system determines a camera-derived path of travel of the vehicle along a road. Responsive at least in part to a geographic location of the vehicle, the system determines a geographic-derived path of travel of the vehicle along the road. Control of the vehicle along the road is based on diminished reliance on the determined geographic-derived path of travel when a geographic location reliability level of the determined geographic-derived path of travel is below a threshold geographic location reliability level. Control of the vehicle along the road is based on diminished reliance on the determined camera-derived path of travel of the vehicle when a camera reliability level of the determined camera-derived path of travel is below a threshold camera reliability level.

Abstract: A vision system of a vehicle includes a camera disposed at a vehicle and having a field of view forward of the vehicle and operable to capture image data. A vehicle-based GPS system is operable to determine a geographical location of the vehicle. A control includes an image processor operable to process image data captured by the camera. Responsive at least in part to processing of captured image data by the image processor to determine lane markings and responsive at least in part to the GPS system and responsive at least in part to map data mapping the road along which the vehicle is traveling, the control is operable to determine an enhanced estimation of the path of travel of the vehicle. The enhanced estimation may be based on reliability levels or weighting factors of the determined lane markings and the map data.

Abstract: A method for vehicular control includes providing a forward viewing camera, a yaw rate sensor, a longitudinal accelerometer, a speed sensor and a control system at the vehicle. While the vehicle is moving, an angular rotational velocity of the vehicle about a local vertical axis is determined, a yaw rate offset is determined, and a longitudinal acceleration is determined. A corrected yaw rate is determined responsive to the determined yaw rate offset of the yaw rate sensor and the determined longitudinal acceleration of the vehicle. The control system determines a projected driving path of the vehicle based at least in part on the determined corrected yaw rate. A hazard condition ahead of the vehicle in the projected driving path is determined at least in part responsive to detecting an object and to the projected driving path. The system automatically applies the brakes of the vehicle responsive to the determined hazard condition.

Abstract: A method for determining a corrected yaw rate for a vehicle includes receiving a first yaw rate input from a yaw rate sensor of the vehicle and determining if the vehicle is moving or stationary. If the vehicle is determined to be moving, the method includes determining a steering angle of the vehicle, and determining an offset correction value based at least in part on a determined speed of the vehicle and the determined steering angle. A yaw rate offset is determined based at least in part on the determined offset correction value and the received first yaw rate input. A second yaw rate input is received from the yaw rate sensor of the vehicle, and a corrected yaw rate value is determined based at least in part on the received second yaw rate input and the determined yaw rate offset.

Abstract: A process for determining a stationary state of a vehicle includes providing a camera and a control having an image processor. Vehicle data is provided to the control by an accelerometer of the vehicle and by at least one of (i) a transmission sensor of the vehicle and (ii) a speed sensor of the vehicle. A determination that the vehicle is stationary is made when at least one of (i) the control determines a jerk value that is approximately zero for a selected duration of time and the control receives vehicle data indicating that the speed of the vehicle was approximately zero for the selected duration of time and (ii) the control determines a jerk value that is approximately zero for a selected duration of time and the control receives vehicle data indicating that the transmission of the vehicle was in ‘Park’ for the selected duration of time.
