    摘要： An apparatus, system, and method are provided for a distributed function-specific buffer arrangement in a communication layer. A first module included in the layered communication architecture reserves a buffer in association with communicating a PDU. The buffer is included in a set of buffers allocated in association with the first module. The first module provides the PDU to a second module included in the layered communication architecture. Providing the PDU to the second module includes storing the PDU to the buffer and transferring ownership of the buffer to the second module. The second module accesses the PDU from a memory space associated with the buffer and releases the ownership of the buffer based on successfully accessing the PDU.

    摘要： The disclosure relates to a cockpit domain control device and a method for detecting a display error by using the cockpit domain control device. The cockpit domain control device includes an execution module and a verification module. The execution module is configured to receive a display request and provide a display configuration based on the display request. The verification module is in communication with the execution module, and the verification module is configured to: receive the display request, receive the display configuration from the execution module, and verify whether the display configuration is consistent with the display request, and if the display configuration is inconsistent with the display request, indicate that there is an error in the execution module. In the disclosure, a cockpit domain control device with an architecture that includs both an execution module and a verification module is used to monitor an error of a display system in a vehicle cockpit, thereby improving the driving safety of the vehicle.

    摘要： The disclosure relates to the technical field of safe driving, and provides a distracted driving detection method, a vehicle-mounted controller, and a computer storage medium. The method includes: A: receiving a facial image of a driver and an external scene image that are synchronously acquired; B: obtaining coordinates of a scene target in the external scene image by using an object detection algorithm, where the scene target is an object capable of providing risk perception for the driver; C: calculating coordinates of a gaze point of the driver in the external scene image based on the facial image of the driver and the external scene image; and D: determining, by comparing the coordinates of the gaze point with the coordinates of the scene target, whether the driver is in a distracted state. The vehicle-mounted controller includes: a memory; a processor; and a computer program stored on the memory and executable on the processor, where the computer program is executed to cause a distracted driving detection method to be performed.

    摘要： The disclosure relates to the field of computer technologies, and specifically provides a log subsystem, a log system, a vehicle log system, and a vehicle, to solve a problem of how to improve performance and flexibility of the log subsystem, reduce system resource occupation, and extend log data applications. To this end, the log subsystem of the disclosure includes a log generation module, a log processing module, and a log output module. Each module runs in a program process, so that system resource occupation is reduced, and performance of the log subsystem is improved. A log output unit designed based on two stages of buffers, two threads, and two modes of wake-up and wait can not only improve log output performance but also avoid causing additional system resource costs. In addition, cross-machine log fusion of log data in a plurality of log subsystems is implemented using another mature open source logging framework, so that a developer can obtain stronger data support, which is conducive to acceleration of system development.
