Abstract: A vehicle control system including a spatial monitoring system includes on-vehicle cameras that capture images, from which are recovered a plurality of three-dimensional (3D) points. A left ground plane normal vector is determined for a left image, a center ground plane normal vector is determined for a front image, and a right ground plane normal vector is determined for a right image. A first angle difference between the left ground plane normal vector and the center ground plane normal vector is determined, and a second angle difference between the right ground plane normal vector and the center ground plane normal vector is determined. An uneven ground surface is determined based upon one of the first angle difference or the second angle difference, and an alignment compensation factor for the left camera or the right camera is determined. A bird's eye view image is determined based upon the alignment compensation factor.

Abstract: A controller processes data from one or more sensors of a subsystem of a vehicle. The processing includes smoothing the data and calculating a mean of the data. The controller identifies a transition point in the processed data where a moving average of the data is less than the mean by a predetermined amount indicating a trend. The controller selects a segment of the processed data subsequent to the transition point, detects the trend in the segment using regression, and extrapolates the detected trend to reach a predetermined fault threshold. The controller predicts a failure of the subsystem based on a slope of the extrapolated trend and provides an indication of the prediction based on the slope to schedule a service for the subsystem.

Abstract: A system in a vehicle includes a lidar system to transmit incident light and receive reflections from one or more objects as a point cloud of points. The system also includes processing circuitry to identify feature points among the points of the point cloud, the feature points being horizontal feature points reflected from a horizontal surface or vertical feature points reflected from a vertical surface. The processing circuitry processes the point cloud by obtaining a normal vector corresponding to each of the points of the point cloud. The normal vector includes a first component associated with a first dimension, a second component associated with a second dimension, and a third component associated with a third dimension.

Abstract: An automatic fault isolation and diagnosis system includes a cloud-based data system having multiple machine-readable troubleshooting procedures stored therein. A vehicle fault code is generated by one of multiple vehicle control devices of a vehicle platform. The fault code defines an issue with at least one system or component of the vehicle platform. A data transfer device within the vehicle platform receives the fault code and forwards the fault code to the cloud-based data system. The fault code is received and analyzed in the cloud-based data system to initially determine if the fault code is directed to and can be automatically corrected by one of the stored machine-readable troubleshooting procedures.

Abstract: A method of operating an electric power steering system installed on a vehicle. The electric power steering system includes a controller that receives a desired assist torque value and supplies a pulse-width modulation duty cycle to an electric motor. The method includes the step of controlling the electric motor to achieve a nominal value of power steering assist torque when the electrical power available to the motor is sufficient to achieve the nominal value of power steering assist torque. The method further includes the step of controlling the electric motor to achieve a reduced value of power steering assist torque less than the nominal value when the electrical power available to the motor is not sufficient to achieve the nominal value of power steering assist torque.

Abstract: A method of identifying a fault in a friction brake actuated by hydraulic brake pressure and configured to decelerate a vehicle road wheel includes detecting, via a first sensor, a vibration at the road wheel and communicating data indicative of the detected vibration to a controller. The method additionally includes detecting, via a second sensor, upon application of the hydraulic brake pressure, a hydraulic brake pressure variation and communicating data indicative of the detected hydraulic brake pressure variation. The method additionally includes comparing, via the controller, the data indicative of the detected vibration with a threshold vibration value and the data indicative of the detected hydraulic brake pressure variation with a threshold hydraulic brake pressure value. Furthermore, the method includes generating a sensory signal indicative of the brake fault when magnitudes of the detected vibration and the detected hydraulic brake pressure variation are greater than their respective threshold values.
