The vehicle gateway module is programmed to transmit the machine-learning program to the vehicle control module; upon receiving the sensor data from the vehicle control module, store the sensor data; and upon establishing a connection with a remote server, transmit the sensor data to the remote server. | 2022-06-30 |
20220204016 | ENHANCED VEHICLE OPERATION - A computer includes a processor and a memory storing instructions executable by the processor to receive operating data including occupant data indicating one or more occupant actions to operate a vehicle and location data specifying a location of a vehicle during collection of the occupant data, assign the operating data to a respective set in a plurality of sets, each set including operating data collected during a different specified period of time from other sets, input the plurality of sets to a machine learning program trained to output an identification of a hazard at a specified location, the hazard being a roadway condition or an obstacle that changes operation of the vehicle from a default operation, output the hazard at the specified location from the machine learning program, and send a message to a vehicle including the hazard at the specified location. | 2022-06-30 |
20220204017 | Architecture For Variable Motion Control Envelope - The technology employs a variable motion control envelope that enables an on-board computing system of a self-driving vehicle to estimate future vehicle driving behavior along an upcoming path, in order to maintain a desired amount of control during autonomous driving. Factors including intrinsic vehicle properties, extrinsic environmental influences and road friction information are evaluated. Such factors can be evaluated to derive an available acceleration model, which defines an envelope of maximum longitudinal and lateral accelerations for the vehicle. This model, which may identify dynamically varying acceleration limits that can be affected by road conditions and road configurations, may be used by the on-board control system (e.g., a planner module of the processing system) to control driving operations of the vehicle in an autonomous driving mode. | 2022-06-30 |
20220204018 | VEHICLE CONTROL USING NEURAL NETWORK CONTROLLER IN COMBINATION WITH MODEL-BASED CONTROLLER - A vehicle control system for automated driver-assistance includes a model-based controller that generates a first control signal to alter an operation of a plurality of actuators of a vehicle based on a reference trajectory for the vehicle, and a present state of the vehicle and actuators. The vehicle control system further includes a neural network controller that generates a second control signal to alter the operation of the actuators of the vehicle based on a reference trajectory for the vehicle, and the present state of the vehicle and actuators. The vehicle control system further includes a combination module that combines the first control signal and the second control signal to operate the actuators based on a combined signal. | 2022-06-30 |
20220204019 | SENSOR CALIBRATION WITH ENVIRONMENT MAP - Methods, systems, and apparatus, including computer programs encoded on computer storage media, for sensor calibration with environment map. In some implementations, a three-dimensional surfel representation of a real-world environment is obtained. One or more surfels of the surfel representation having a particular classification of the different classifications are selected. Input sensor data from one or more sensors installed on an autonomous or semi-autonomous vehicle are received. The input sensor data is compared to the surfel representation to identify one or more differences between the observation and the surfel representation. At least one sensor of the one or more sensors is calibrated using the one or more differences between the observation and the surfel representation. | 2022-06-30 |
