Abstract: Techniques are described to enable a vehicle, such as an autonomous vehicle, to steer and/or apply brakes on a road when a failure condition occurs. An example method for autonomous driving operation includes receiving a reduced set of location information that describes a location of the autonomous vehicle on a road; receiving a reduced set of trajectory information where the autonomous vehicle is expected to be driven; determining a driving path information where the autonomous vehicle is expected to be driven; and in response to determining an occurrence of a fault condition: sending a first instruction to cause the autonomous vehicle to steer the autonomous vehicle using at least the driving path information and the reduced set of location information, and sending a second instruction to cause the autonomous vehicle to apply brakes.

Abstract: Disclosed are devices, systems and methods for a monitoring system for autonomous vehicle operation. In some embodiments, a vehicle may perform self-tests, generate a report based on the results, and transmit it to a remote monitor center over one or both of a high-speed channel for regular data transfers or a reliable channel for emergency situations. In other embodiments, the remote monitor center may determine that immediate intervention is required, and may transmit a control command with high priority, which when received by the vehicle, is implemented and overrides any local commands being processed. In yet other embodiments, the control command with high priority is selected from a small group of predetermined control commands the remote monitor center may issue.

Abstract: Devices, systems, and methods for redundant braking systems and architectures are described. An example method for controlling a vehicle includes receiving, by a braking system, a first set of commands generated by a primary brake controller and a primary vehicle control unit (VCU) comprising multiple processors, receiving a second set of commands generated by the primary VCU and a secondary brake controller, receiving a third set of commands generated by a secondary VCU and the primary brake controller, receiving a fourth set of commands generated by the secondary VCU and the secondary brake controller, and selecting, based on an arbitration logic, exactly one of the first, second, third, and fourth sets of commands to operate the braking system, wherein the primary VCU and the secondary VCU are configured in a master/slave architecture.

Abstract: The disclosed technology enables automated parking of an autonomous vehicle. An example method of performing automated parking for a vehicle comprises obtaining, from a plurality of global positioning system (GPS) devices located on or in an autonomous vehicle, a first set of location information that describes locations of multiple points on the autonomous vehicle, where the first set of location information are associated with a first position of the autonomous vehicle, determining, based on the first set of location information and a location of the parking area, a trajectory information that describes a trajectory for the autonomous vehicle to be driven from the first position of the autonomous vehicle to a parking area, and causing the autonomous vehicle to be driven along the trajectory to the parking area by causing operation of one or more devices located in the autonomous vehicle based on at least the trajectory information.

Abstract: Provided herein is a system and method for monitoring the health of a steering system of a vehicle. Methods can include: receiving location information and motion information associated with a vehicle; determining, from the location information, a map-matched road segment associated with the location information; establishing a geometry of the map-matched road segment based on map data of a map database; filtering the motion information associated with the vehicle to establish a baseline movement of the vehicle; determining, during the baseline movement of the vehicle, steering angle input received at a steering system of the vehicle; determining, from the steering angle input received at the steering system of the vehicle, a steering angle offset; and causing the steering angle offset to be applied to the steering system of the vehicle.

Abstract: Devices, systems, and methods for remote detection and ranging are described. In an embodiment, a remote sensing method includes obtaining data points that are spatially distributed and have respective intensity values, by performing a remote detection and ranging operation, determining a spatial autocorrelation of a set of data points, out of the data points, based on a difference in distances between data points in the data points, determining an intensity weight multiplier based on a reference intensity value of the data points and an average intensity value of the data points, and determining a quality score of the set of data points by applying the intensity weight multiplier to the spatial autocorrelation of the set of data points; and identifying, based on the quality score, whether the set of data points includes one or more data points that are created by a noise source.
