  • Publication number: 20160244069
    Abstract: A yaw rate estimation system for a vehicle includes a control receiving inputs indicative of (i) a first yaw rate determined by a yaw rate sensor of the vehicle, (ii) a second yaw rate derived from ABS wheel sensors of the vehicle, (iii) a third yaw rate derived from a lateral acceleration of the vehicle and (iv) a fourth yaw rate derived from a steering wheel angle, wheel angle and rate of change of steering wheel angle. The control is operable to process the inputs to estimate the yaw rate of the vehicle, with the estimated yaw rate derived from the inputs.

  • Patent number: 9340227
    Abstract: A lane keep assist system for a vehicle includes a forward facing camera and an image processor. The forward facing camera is disposed at a vehicle and has a forward field of view exterior of the vehicle. The image processor is operable to process image data captured by the forward facing camera. The lane keep assist system is operable to process image data to determine lane markers in the field of view and to determine a time to lane crossing value. The lane keep assist system determines a first time to lane crossing value via a first algorithm and a second time to lane crossing value via a second algorithm. The lane keep assist system is operable to apply a steering signal to adjust the steering of the vehicle at least in part responsive to the determined first and second time to lane crossing values.

  • Publication number: 20150291215
    Abstract: A control system of a vehicle includes an image sensor and a control having an image processor. The image sensor is disposed at the vehicle and has a field of view exterior and forward of the vehicle. The image processor is operable to process image data captured by the image sensor to determine a curvature of a road being traveled by the vehicle. Responsive at least in part to processing by the image processor of captured image data, the control is operable to determine tangents at locations along the determined curvature. Responsive to determination of the tangents, the control is operable generate an output to adjust the vehicle steering to guide the vehicle in a direction that generally corresponds to determined tangents at respective locations of the vehicle's path of travel along the curvature of the road.

  • Publication number: 20150002670
    Abstract: A trailering assist system for a vehicle includes a camera disposed at a vehicle, with the camera having a field of view rearward of the vehicle that encompasses a trailer that is being towed by the vehicle. The camera is operable to capture image data. A control of the system includes an image processor operable to process captured image data. Responsive to input of vehicle parameters and processing of captured image data by the image processor, the trailering assist system is operable to determine an estimated trailer angle and an estimated vehicle steering wheel angle. The control compares the estimated vehicle steering wheel angle to a measured or determined or actual vehicle steering wheel angle to determine an error value. The control is operable to generate an output when the error value is at or above a threshold level.

  • Publication number: 20140005907
    Abstract: An adaptive cruise control system for a vehicle includes a camera having a field of view forward of a vehicle and operable to capture image data. A traffic situation classifier, responsive to captured image data, determines a traffic condition ahead of the vehicle. A control is operable to process captured image data and, at least in part responsive to the traffic situation classifier, generate an output to accelerate or decelerate the vehicle to establish a desired or appropriate velocity of the vehicle based on the determined traffic condition and image data processing.

  • Patent number: 8373581
    Abstract: In a mobile control node system and method for a vehicle (630), the mobile control node (624) can interact, via a bi-directional radio link (642), with a transceiver processor unit (628) in the vehicle. The transceiver processor unit (628) is connected to a vehicle control system (120) and allows the mobile control node (624) to function as an input and output node on a vehicle control network (632), allowing remote control of the vehicle and providing functions such as remote or passive keyless entry. Additionally, the system provides a vehicle location function wherein the range and bearing between the mobile control node (624) and the vehicle (630) can be determined and displayed on the mobile control node (624).
