Abstract: The present disclosure relates to apparatuses and methods for controlling a laser headlight of a vehicle. One example method includes obtaining first reference information, determining, based on the first reference information, that the vehicle has a collision risk or that a collision occurs to the vehicle, and generating first indication information that is used to turn off the laser headlight of the vehicle. The first reference information includes at least one of first map information, first information sensed by a roadside device, second information sensed by a sensing device on the vehicle, or first control information in the vehicle. When it is determined that the vehicle has a collision risk or that a collision occurs to the vehicle, the first indication information that is used to turn off the laser headlight of the vehicle is generated, so as to turn off the laser headlight.

Abstract: A controller may generate a packet, and send the packet to an electronic control unit. The packet includes a plurality of bits and control information. The plurality of bits may indicate whether the electronic control unit controls a plurality of objects (for example, actuators or functions) based on the control information. The plurality of bits are in a one-to-one correspondence with the plurality of objects. In this way, the electronic control unit associated with the plurality of objects can control the plurality of objects based on the control information.

Abstract: This application provides a method for training a neural network model and an apparatus. The method includes: obtaining annotation data that is of a service and that is generated by a terminal device in a specified period; training a second neural network model by using the annotation data that is of the service and that is generated in the specified period, to obtain a trained second neural network model; and updating a first neural network model based on the trained second neural network model. In the method, training is performed based on the annotation data generated by the terminal device, so that in an updated first neural network model compared with a universal model, an inference result has a higher confidence level, and a personalized requirement of a user can be better met.

Abstract: This application discloses a method for controlling traffic in a packet-based network. In the method, after receiving a control packet from a transmit end, an intermediate node between the transmit end and the receive end sends a control packet at the head of a first control queue based on a first duration, wherein the first duration is obtained based on a committed burst size (CBS) and a first committed information rate (CIR), and the intermediate node is configured to send a packet of a first transmit end to a first receive end in the packet-based network. After sending the control packet in the control queue, the intermediate node sends a first data packet set at the head of a data queue based on the sent control packet, wherein the first data packet set comprises C data packets, and C is an integer greater than or equal to 1
