Abstract: A device for recording user operation data for a remotely controlled vehicle includes a memory configured to record user operation data. The user operation data is associated with a specific user of the remotely controlled vehicle and includes outgoing operation commands that affect operation of the remotely controlled vehicle. The outgoing operation commands is transmitted to the remotely controlled vehicle and received via a remote controller of the remotely controlled vehicle.

Abstract: A device for recording user operation data for a remotely controlled vehicle includes a memory off-board the remotely controlled vehicle and a housing receiving the memory. The memory is configured to record user operation data comprising outgoing operation commands that affect operation of the remotely controlled vehicle. The outgoing operation commands are received via a remote controller of the remotely controlled vehicle and transmitted to the remotely controlled vehicle. The housing is removable from the remote controller and more resistant to destruction than the rest of the remote controller.

Abstract: A system for controlling a motion of a vehicle includes a memory to store a set of analytical functions corresponding to a set of patterns of elementary paths. Each pattern represents a continuous path and each analytical function is determined for a corresponding pattern to provide an analytical solution for input states of the vehicle defining a continuous path connecting the input states by a sequential compositions of the elementary paths following the corresponding pattern. The system includes a path planner to select from the memory, in response to receiving an initial state and a target state of the vehicle, an analytical function corresponding to a minimum cost of the continuous curvature path connecting the initial state with the target state and to analytically determine parameters of the continuous curvature path using the selected analytical function and a controller to control the motion of the vehicle according to the parameters of the continuous curvature path.

Abstract: A data transmission processing method is provided for a communication device. The method includes calculating a packet-error-rate level parameter after a basic adjustment process, if it is detected that the basic adjustment process is performed on a modulation and encoding policy of a sending end during a data packet transmission process; obtaining the packet-error-rate change information by comparing a packet-error-rate level parameter before the basic adjustment process with a packet-error-rate level parameter after the basic adjustment process; and performing an upgrade adjustment process on the modulation and encoding policy that is adjusted by the basic adjustment process, if the packet-error-rate change information satisfies a preset adjustment processing condition.

Abstract: 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.
