Embodiments disclose a vehicle-mounted device upgrade method and a related device. The method may be applied to an intelligent vehicle, the intelligent vehicle includes a vehicle-mounted control device, and the method may include: receiving, by the vehicle-mounted control device, a first partial key sent by the communications device; restoring, by the vehicle-mounted control device, a first key by using the first partial key and a second partial key that is stored on the vehicle-mounted control device; and performing, by the vehicle-mounted control device, secure processing on a first upgrade file by using the first key, to obtain the securely processed first upgrade file, where the secure processing includes generating first message authentication code (MAC), and the securely processed first upgrade file includes the first upgrade file and the first MAC. According to this application, the vehicle-mounted device can be securely and efficiently upgraded.

Vehicle-mounted device upgrade method and related device

A self-driving safety evaluation method, including determining Rbased on a risk value of a vehicle in a shadow driving mode in a first measurement unit, where Ris a risk value of the vehicle in the shadow driving mode in a plurality of measurement units, and determining Rbased on a risk value of the vehicle in a self-driving mode based on a preset route in the first measurement unit, where Ris a risk value of the vehicle in the self-driving mode based on the preset route in the measurement units, where Rand Rare used to determine whether safety of the vehicle in the self-driving mode meets a requirement.

Self-driving safety evaluation method, apparatus, and system

A method and device for mitigating passenger-related item loss in a travel-for-hire context are disclosed. An item within a vehicle passenger region is identified, and the identified item is associated with an identified passenger. A presence of the identified item is detected within the vehicle cabin passenger region in response to detecting an exit of the identified passenger, and an announcement message is generated based on the presence of the identified item within the vehicle cabin passenger region.

Passenger-related item loss mitigation

A vehicle-mounted device upgrade method and a related device. The method may be applied to a vehicle-mounted system, a vehicle-mounted control device and one or more to-be-upgraded vehicle-mounted devices, and the method may include: obtaining, by the vehicle-mounted control device, a vehicle-mounted upgrade package, where the vehicle-mounted upgrade package includes a plurality of upgrade files, and each upgrade file is used to upgrade at least one to-be-upgraded vehicle-mounted device; performing, by the vehicle-mounted control device, security verification on the plurality of upgrade files; and sending, by the vehicle-mounted control device, a target upgrade file to a target to-be-upgraded vehicle-mounted device that is to be upgraded by using the target upgrade file, where the target upgrade file is an upgrade file on which security verification succeeds in the plurality of upgrade files. According to this application, the vehicle-mounted device can be securely and efficiently upgraded.

A driving intention determining method includes obtaining status information of traffic targets in a driving environment, where the traffic targets include a traffic target in a moving state and traffic targets in a static state, and status information of the traffic targets in a static state includes at least indication information of a traffic sign and road boundary information, determining a risk field of the driving environment based on the status information of the traffic targets in the driving environment, for any other vehicle in the driving environment, determining a driving track of the other vehicle in the driving environment based on the risk field, and determining driving intention of the other vehicle based on the driving track of the other vehicle in the driving environment.

Driving intention determining method and apparatus

A system for reducing analog noise in a noisy channel, comprising: an interface configured to receive analog channel output comprising a stream of noisy binary codewords of a linear code; and a computation component configured to perform the following: for each analog segment of the analog channel output of block length: calculating an absolute value representation and a sign representation of a respective analog segment, calculating a multiplication of a binary representation of the sign representation with a parity matrix of the linear code, inputting the absolute value representation and the outcome of the multiplication into a neural network for acquiring a neural network output, and estimating a binary codeword by component-wise multiplication of the neural network output and the sign representation.

System and a method for error correction coding using a deep neural network

A method and device for mitigating passenger-related item loss in a travel-for-hire context are disclosed. An item within a vehicle passenger region is identified, and associated the identified item with a passenger identified by a passenger identifier. A vehicle cabin inventory database is updated with an entry based on the identified item associated with the passenger identifier. A presence of the identified item is detected within the vehicle cabin passenger region when a passenger exit event occurs, and message data is generated including the entry that relates to the identified item based on the presence of the identified item within the vehicle cabin passenger region.
