REAL-TIME TRACKING AND FILTERING OF ESTIMATED DRIVELINE RATIOS
A computer system (e.g., an on-board vehicle computer system) creates or updates a mapping of transmission gears and respective driveline ratios during operation of the vehicle. The system obtains a current engine speed and vehicle speed and calculates a current driveline ratio for the vehicle based on the current engine speed and vehicle speed. If the driveline is engaged, the system updates the mapping based at least in part on the current driveline ratio. Performing the update may include adding a new transmission gear or updating an existing transmission gear in the mapping, or removing a duplicate transmission gear from the mapping. Applications include cruise control, predictive cruise control, predictive shifting, and selecting a gear for a specific purpose (e.g., for descending a hill).

The disclosed vehicle control system verification device is equipped with a storage device that stores programs for verifying the safety of the logical architecture of a vehicle control system, and a processor that reads the programs from the storage device and verifies the safety of the logical architecture. On the basis of safety analysis result information that is supplied, the processor executes a process for verifying whether the logical architecture has logical functions corresponding to the safety analysis result.
Adaptive vehicle control
A controller includes a processor programmed to determine, for a vehicle, a first control input based on input data and first reference parameters. The processor is further programmed to operate the vehicle according to the first control input. Based on operating data of the vehicle for an operating condition, the processor determines a second control input for the vehicle. Operating the vehicle according to the second control input reduces a cost of operating the vehicle relative to operating the vehicle according to the first control input. The processor is further programmed to determine, based on the second control input, second reference parameters. The controller generates a third control input based on the second reference parameters and the input data. A cost of operating the vehicle according to the third control input is reduced relative to the cost of operating the vehicle based on the first control input.
Vehicle System and Method for Operating a Functionality, Designed for at Least Partially Automated Driving or Parking, in a Vehicle
A vehicle system has a first operating mode and a second operating mode. The first operating mode is configured to execute a functionality of the vehicle system in driving mode based on acquired sensor signals and to operate the vehicle in an at least partially automated manner through interventions in vehicle guidance based on the result of the executed functionality. The second operating mode is configured to change a degree of the effectiveness of the interventions in the driving mode and/or a degree of the effectiveness of an operation decoupled from the vehicle guidance, and, when executing a functionality of the vehicle system with a changed degree of the effectiveness of an intervention in the vehicle guidance and/or a changed degree of the effectiveness of an operation decoupled from the vehicle guidance, to acquire operating data of the vehicle and/or feedback data from the user of the vehicle.

The method further determines the information related to the lane change of the target vehicle based on the information related to the environment of the target vehicle using a machine-learning network. A weighting of the plurality of features of the environment of the target vehicle within the machine-learning network is based on the two or more weighting factors for the two or more groups of features.
Driving model generation device, driving model generation method, driving evaluation device, driving evaluation method, and driving support system
A driving model generation device is provided that enables driving evaluation according to a traveling situation of a vehicle. A vehicle is provided with a vehicle state detector, which detects a vehicle state quantity that changes according to a driving operation by a driver. A model generator generates a driving model, which is a reference related to a specific driving operation, based on the vehicle state quantity at the time the driver starts the specific driving operation and the vehicle state quantity at the time the specific driving operation is finished. A driving evaluator evaluates the driving skill of the driver by comparing the driving operation of the driver presented by a detection result of the vehicle state detector to the driving model generated by the model generator.
Motion Controller for Real-Time Continuous Curvature Path Planning
A system for controlling a motion of a vehicle from an initial state to a target state includes a path planner to determine a discontinuous curvature path connecting the initial state with the target state by a sequential composition of driving patterns. The discontinuous curvature path is collision-free within a tolerance envelope centered on the discontinuous curvature path. The system further includes a path transformer to locate and replace at least one treatable primitive in the discontinuous curvature path with a corresponding continuous curvature segment to form a modified path remaining within the tolerance envelope. Each treatable primitive is a predetermined pattern of elementary paths. The system further includes a controller to control the motion of the vehicle according to the modified path.
