A method of mitigates RF interference from an RF interferer. An RF signal is received at an RF transceiver during a time period. The RF signal that includes, for at least a portion of the time period, an interference signal having a cyclic transmission pattern with at least one deterministic feature. The received RF signal is analyzed in order to determine timing information for the at least one deterministic feature and the associated interference signal cyclic transmission pattern. Transmission of the RF signals from the RF transceiver are synchronized with the interference signal transmission pattern based on the determined timing information to mitigate interference between the RF signals and the interference signal.

The statistical analysis may include application of order statistic filtering.

Abstract
A brake boost assist system for use with a master cylinder of a motor vehicle braking system, includes an inductive sensing system. The inductive sensing system has sensing devices carried on an input member and an output member, where the input and output members are coupled to respective ones of an input rod and an output rod of the brake boost assist system. Movement of the input and output members relative to one another, and relative to a fixed element of the inductive sensing system positioned within the brake boost assist system, enables an accurate estimation of the distance of a pedal gap which separates faces of the input and output rods. The accurate estimation of the pedal gap distance enables a more accurate determination to be made of the braking force required for any given pedal stroke input by an operator of the vehicle during a braking action.

APPARATUS AND METHOD FOR DETECTING ALIGNMENT OF SENSOR IN AN AUTOMOTIVE DETECTION SYSTEM
In automotive detection systems, sensor alignment is important to proper operation of the system. A portion of automobile or vehicle 50 is equipped with detection system 10, including forward-looking detection sensor module 12C, illustrating misalignment of detection sensor module 12C. Vehicle 50 is moving with a vehicle velocity Vh. A target object 51, which is detected by detection sensor module 12C, can be present in the path of vehicle 50. However, due to misalignment error, target object 51 is detected as target object 53, which differs from the actual real target object 51. As a result, there exists a true target angle θref for the real target object 51 and a detected target angle θerr for the detected target object 53, where these angles are measured from a line 55 that extends from vehicle 50, in its forward direction, extending along the velocity Vh, which can be considered to extend along the detection boresight of the detection sensor module 12C. An automotive detection system includes a signal transmitter and a receiver, which generates receive signals indicative of reflected signals. A processor (i) receives the receive signals, (ii) processes the receive signals to generate detections of one or more objects in the region, each of the detections being associated with a position in a two-dimensional orthogonal coordinate system in a plane in which the sensor is moving, (iii) detects a pattern of detections in the two-dimensional orthogonal coordinate system by determining a quantity of detections having coordinates in a rectangular region within the two-dimensional orthogonal coordinate system, (iv) determines an angle of an axis of the rectangular region with respect to a reference direction in the two-dimensional orthogonal coordinate system, and (v) determines an angle of misalignment of the sensor from the angle of the axis of the rectangular region with respect to the reference direction. The detection system may be a radar system or a LiDAR system. Preferably, the processor filters the detections by limiting a quantity of detections in each of a plurality of two-dimensional grids within the two-dimensional orthogonal coordinate system.
The systems and methods of the present disclosure utilize an advantageous data transmission protocol, which facilitates determining and compensating for transmission delay between nodes in a communications network in order to correlate timing information across multiple nodes. According to the systems and methods presented herein, data may be transmitted from a first node to a second node, wherein the transmitted data includes each of (i) timing information (as measured by a first timing mechanism associated with the first node) characterizing a first set of data and (ii) a transmission time (as also measured by the first timing mechanism). A receiving time (as measured by a second timing mechanism associated with the second node) for the first set of data, may also be determined. Based on these parameters timing information characterizing the first set of data in the context of the second timing mechanism may then be determined.
In an embodiment, a localization module can provide coordinates of the vehicle relative to the Earth and relative to the drivable surface, both of which are precise enough to allow for self-driving, and further can compensate for a temporary lapse in reliable GPS service by continuing to track the car's position by tracking its movement with inertial sensors (e.g., accelerometers and gyroscopes) and RADAR data. The localization module bases its output on a geolocation relative to the Earth and sensor measurements of the drivable surface and its surroundings to determine where the car is in relation to the Earth and the drivable surface.

APPARATUS AND METHOD FOR MITIGATING INTERFERENCE IN AN AUTOMOTIVE RADAR SYSTEM
A system and method for mitigating interference in a frequency-modulated continuous-wave radar processing system is defined. Random inter-pulse jitter is implemented in a transmitted radar signal to prevent identification of false {racks due to interfering radar signals. Random intra-pulse jitter of time and/or frequency is implanted to create spreading of false targets and provide a method to distinguish false targets from true targets. Adjacent sensors in a multi-sensor radar" system are alternatingly configured to transmit either upward ramping or downward ramping frequencies to mitigate interference between adjacent sensors in the same radar system.
A system for characterizing a moving object performs a cluster trajectory orientation process associated wi th clusters of detected points in each of a set. of scans to estimate the heading of a non-point target. The cluster txajectory orientation process performs a principal component analysis on a corresponding position data matrix representing coordinates of the clusters of points for each of a set of scans and compares resulting eigenvec tors to a heading of the cluster averages to generate a heading estimate. The heading estimate is combined with velocity estimates from a point target based tracking process and a Doppler-azinnith profile process in a weighted combination based on target attributes to improve the accuracy and performance of the system.

Systems and methods are presented herein for improved cross-path detection between a host vehicle and a target object. In general, the cross-path angle may be determined by solving an optimization problem which minimizes variance, across multiple time points, of a perpendicular path distance at each time point between a trajectory of target object and a common reference position (across the multiple time points) for the host vehicle. Advantageously, a cross-traffic alert or other feedback may be triggered based at least partially on whether the target object is within a region of interest, wherein the region of interest is determined at least in part based on the estimated cross-path angle.
