Hybrid electric vehicle and method of controlling the same to avoid collision thereof

A hybrid electric vehicle and a method of controlling the same are provided to avoid a collision thereof attributable to erroneous operation of an accelerator pedal. The method includes determining whether an accelerator pedal is erroneously operated in the situation in which an obstacle is detected to be present in the traveling path. In response to determining that the accelerator pedal is erroneously operated, the method includes switching the driving mode to a mode in which an engine is disconnected from a driving shaft and a motor generates driving force. The number of revolutions per minute (RPM) of the engine is then adjusted based on the extent to which the accelerator pedal is operated and the torque of the motor is adjusted based on a first vehicle speed and the distance to the obstacle.

MODULAR RADAR ELEMENT WIRELESS SYNCHRONIZATION
20230160998 · 2023-05-25 ·

The present disclosure is directed to a modular radar apparatus and to methods for using a modular radar apparatus. Two or more modules of the radar apparatus may each include a reference signal antenna where a synchronization signal generated at a first module may be sent to a second module via a pair of respective reference signal antenna. When the synchronization signal is received by the second module, that signal may be provided to a phase locked loop (PLL) to synchronize timing of the second module with the first module. The PLL or a multiplier circuit could then generate signals with timing synchronized to the synchronization signal yet at frequencies higher than the synchronization signal. This synchronized timing may allow transmitted radar signals to be synchronized in time with received reflected radar signals more accurately because effects of transmitting synchronization signals via wired interconnects between modules is eliminated.

Ground truth data may be too sparse to supervise training of a machine-learned (ML) model enough to achieve an ML model with sufficient accuracy/recall. For example, in some cases, ground truth data may only be available for every third, tenth, or hundredth frame of raw data. Training an ML model to detect a velocity of an object when ground truth data for training is sparse may comprise training the ML model to predict a future position of the object based at least in part on image, radar, and/or lidar data (e.g., for which no ground truth may be available). The ML model may be altered based at least in part on a difference between ground truth data associated with a future time and the future position.

The method includes: acquiring first orientation data sent by a UWB base station arranged on a target following apparatus and a following mode sent by a UWB beacon arranged on a target to be followed; processing, based on the following mode, the first orientation data to obtain second orientation data including a current distance between a target position and the UWB base station, and a second azimuth angle of a line where the target position and the UWB base station are located with respect to a current direction of a movement of the target following apparatus; and comparing the second orientation data with preset orientation data to obtain a comparison result, and controlling the target following apparatus to perform target following according to the comparison result.

Collision avoidance assisting apparatus

Disclosed is a collision avoidance assisting apparatus which can execute an automatic braking process and an automatic steering process for avoiding collision with an obstacle. When the magnitude of a steering angle exceeds a predetermined threshold, the collision avoidance assisting apparatus determines that a driver has an intention of avoiding the collision by a steering operation and stops the automatic braking process and the automatic steering process. However, in such a case, the automatic braking process and the automatic steering process may be stopped when the steering angle exceeds the threshold as a result of execution of the automatic steering process. In view of this, when both the automatic braking process and the automatic steering process are being executed, the collision avoidance assisting apparatus continues the automatic braking process and the automatic steering process even when the magnitude of the steering angle is greater than the predetermined threshold.
