    Abstract: A high-accuracy positioning method and a corresponding positioning system and positioning terminal are provided, and may be used in the field of intelligent vehicle technologies. In this positioning method, a real-time kinematics (RTK) positioning technology and a multi-receiver constraint MRC positioning technology are used to determine a location of a to-be-positioned target. In this positioning method, an RTK error correction model and an MRC error correction model may be preconstructed according to a big data technology. The RTK error correction model is used to provide a correction value for an original detection value obtained based on the RTK positioning technology. The MRC error correction model is used to provide a correction value for an original detection value obtained based on the MRC positioning technology. Then, the correction values are used to calculate the location of the to-be-positioned target.

    Abstract: An example method includes obtaining, by a first local traffic control unit (TCU), a traffic application type and first traffic information. The first local TCU can then determine an interaction coverage area based on the traffic application type and the first traffic information. The first local TCU can then determine a first area and send the traffic application type and the first traffic information to a global TCU, where a second local TCU is a local TCU adjacent to the first local TCU, where the first area is at least one overlapping area between a management area of a third local TCU and the interaction coverage area, and where the third local TCU is a local TCU not adjacent to the first local TCU.

    Abstract: A WLED driver and a drive control method. The WLED driver includes 2N2 switches, and each CS module includes 2N switches, where one end of each of N switches in the 2N switches is connected to an output end of an error amplifier, another end of each of the N switches is connected to a gate of each of N NMOS transistors, one end of each of remaining N switches is connected to a negative input end of the error amplifier, and another end of each of the remaining N switches is connected to a positive input end of each of N feedback resistors. After a control circuit generates a clock control signal group Φgroup. the control circuit controls switching actions of the 2N2 switches on a time-division basis according to the clock control signal group Φgroup.

    Abstract: A data input method and apparatus, and user equipment are provided. The method includes: when it is determined that an operation of a user on the user equipment UE is not performed in a preset display area, deliver an event corresponding to the operation to a first operating environment for processing, where the preset display area runs in a second operating environment of the UE, and the second operating environment has a higher security level than the first operating environment. This can better improve security of an event generated when the user operates a program that runs in a Normal World of the user equipment, and can directly operate an event that runs in the Normal World.
