  • Patent number: 10457328
    Abstract: A safety system for a vehicle providing a road departure protection feature comprises a camera, mounted to the vehicle to provide a view of a driving direction of the vehicle, and an electronic control unit connected to the camera. The electronic control unit includes instructions for analyzing the image and comparing the roadway path to the predicted vehicle path. The electronic control unit determines a vehicle roadway departure is occurring when the predicted vehicle path differs from the roadway path by a predetermined threshold, and then determines at least one corrective action to return the vehicle path to the roadway path. The safety system sends instructions to apply at least one corrective action with at least an electronic stability control system.

  • Patent number: 9989606
    Abstract: An image dataset comprises multiple shots of imaging data acquired using a magnetic resonance imaging (MRI) scanner (10). The signal power of each shot of the image dataset is normalized (24) to a reference signal power to generate a power normalized shot representation having total signal power matching the reference signal power. A reconstructed image is generated (26) from the power normalized shot representations. Odd/even phase correction (22) may also be performed on the image dataset. The phase correction, normalizing, and generating operations are suitably performed by an electronic data processing device (20).

  • Patent number: 9845092
    Abstract: A maneuvering assistance system for a vehicle determines a scalar field representing the probability of collision with an object at locations proximate to the vehicle with a controller located within the vehicle. The probability of collision is determined based on information received indicative of vehicle motion and the proximity of the object to the vehicle, and the field of collision probability is then communicated as a visual representation to an operator of the vehicle.

  • Patent number: 9751561
    Abstract: A disclosed method of maneuvering a vehicle-trailer unit in reverse travel with a backing system includes, among other things, determining that the vehicle-trailer unit is backing up with an electronic control unit for the backing system. A current hitch angle is determined, which represents the relative angle between the vehicle and the trailer with the electronic control unit. A requested hitch angle rate of change versus distance traveled is calculated with the electronic control unit, wherein the requested hitch angle rate of change is based upon an input which provides a requested hitch angle rate of change signal value. A steering angle is calculated with the electronic control unit based upon the requested hitch angle rate of change, wherein the steering angle will allow movement of the vehicle-trailer unit in the reverse direction to obtain the requested hitch angle rate of change; and a request is sent to a steering system to provide the steering angle.
