  • Patent number: 11933627
    Abstract: A high-definition map building method includes determining a key node describing information about a key position of a lane attribute change, determining a key node layer based on a position of the key node and an attribute of the key node, and determining a high-definition map based on a navigation map and the key node layer. The navigation map provides road-level navigation information, and the high-definition map provides lane-level navigation information.

  • Patent number: 11541880
    Abstract: An information processing method, a server, and an intelligent mobile robot, so that when the intelligent mobile robot encounters a danger, the intelligent mobile robot exchanges information with the server to achieve a purpose of escaping from a scene to a safe place. The method includes: receiving, by a server, a danger alarm sent by an intelligent mobile robot, where the danger alarm is used to indicate that the intelligent mobile robot detects a dangerous event; determining, by the server, a safe position for the intelligent mobile robot, where the safe position is a position in which the dangerous event does not occur currently; and sending, by the server, an escape instruction to the intelligent mobile robot, where the escape instruction includes the safe position.

  • Patent number: 11294675
    Abstract: A method for accessing a memory of a multi-core system, a related apparatus, a system, and a storage medium involve obtaining data from a system memory according to a prefetch instruction, and sending a message to a core that carries the to-be-accessed data. Each segment of data is stored in an intra-core cache based on the prefetch instruction.

  • Publication number: 20210148988
    Abstract: Estimating a battery state of health (SOH) is described. The state of heath is estimated by obtaining a partial charge or discharge capacity of a target battery in a state of charge (SOC) interval of each of a plurality of SOCs. First dV/dSOC data is separately calculated for each SOC in an mth preset battery capacity based on the mth preset battery capacity and the partial charge or discharge capacity in the SOC interval of each SOC. A smallest overall dV/dSOC data deviation is determined from all overall dV/dSOC data deviations corresponding to M preset battery capacities. A preset battery capacity is determined corresponding to the smallest overall dV/dSOC data deviation as a retention capacity of an aged target battery. The retention capacity of the aged target battery is divided by a retention capacity of the target battery in a new battery state, to obtain the SOH estimate of the target battery.
