Publication number: 20180229723Abstract: A computer system receives data sets for a driving maneuver at a location, such as data regarding a state of a vehicle, an external environment indicated by external sensors, and user feedback regarding the driving maneuver. Data sets may be collected from users having various demographic and behavioral attributes. Users may be selected using design of experiment (DOE) algorithms to cover a wide range of possible combinations. A stochastic response surface model (SRSM) is generated that relates sensor data (vehicle state and environmental) to user feedback regarding safety and comfort. The SRSM may be generated using Gaussian process regression (GPR) in order to model uncertainty. The SRSM is then used to generate a control model using an optimization under uncertainty (OUU) algorithm.Type: ApplicationFiled: February 15, 2017Publication date: August 16, 2018Inventors: Zhen Jiang, Yan Fu, Yuzhou Li

Publication number: 20180229768Abstract: A lane-keeping-assist system suitable for use on an automated vehicle includes a camera, a steering-actuator, and a controller. The camera detects a lane-marking of a travel-lane traveled by a host-vehicle. The steering-actuator controls a travel-direction of the host-vehicle. The controller is in communication with the camera and the steering-actuator. The controller determines a lane-width of the travel-lane and determines a centerline of the travel-lane based on the lane-marking. The controller further determines an offset-position of the host-vehicle within the travel-lane based on the lane-marking. The controller further determines a clearance between the host-vehicle and the lane-marking based on the offset-position. The controller further determines an adaptive-threshold based on the lane-width.Type: ApplicationFiled: March 9, 2017Publication date: August 16, 2018Inventors: Liang Ma, Michael I. Chia

Publication number: 20180229769Abstract: A steer torque manager for an advanced driver assistance system of a road vehicle and a method therefor. A driver-in-the-loop functionality determines when to hand over control to a driver. A wheel angle controller uses an advanced driver assistance system wheel angle request to produce an overlay torque request to be added to a torque request from an electrical power assisted steering. The steer torque manager controls the driver-in-the-loop functionality based on amplitude and frequency content of a torsion bar torque related signal which is filtered to attenuate an amplitude thereof at frequencies up to 2 Hz. The overlay torque request to be provided by the wheel angle controller is modulated based on a measure of driver activity derived from the filtered torsion bar torque related signal, where more recent values are weighted higher than older values, using a time window of 0.5-3 seconds.Type: ApplicationFiled: February 5, 2018Publication date: August 16, 2018Applicant: VOLVO CAR CORPORATIONInventors: Lars Johannesson MARDH, Malin HAGLUND
