Abstract: A flat spot-proof tire, and a vehicle. The flat spot-proof tire comprises a tread, a cap ply, a belt ply and a carcass. The rubber hardness of the tread is 68-78 Shore A. The cap ply is formed by nylon cords having linear density of 90-140 pieces per 100 mm. The belt ply is formed by steel cords, which comprise HT steel wires and/or SHT steel wires. The carcass is formed by polyester cords having linear density of 100-120 pieces per 100 mm. The flat spot-proof tire and the vehicle use suitable industrial rubber and polyester fiber material, have a specific size design and undergo an optimized inflation process after vulcanization such that the long-term flat spot effects of the tire can be mitigated, and the jitter of the vehicle during high-speed traveling can be reduced.

Abstract: A multi-way valve, related to the technical field of control valves, is used to solve the problem of large occupied space, complicated control, and high cost, because of the use of two driving devices for controlling a three-way proportional valve and a two-way proportional valve, where a driving device is connected to a first valve core in a transmission way, and the first valve core is provided with a first matching structure, and a second valve core is provided with a second matching structure that matches the first matching structure. In the first matching state, the first valve core rotates alone and the second valve core remains stationary; in the second matching state, the first valve core rotates to drive the second valve core to rotate synchronously.

Abstract: The present disclosure provides an identity recognition method, including: receiving registration information of a first user; binding a first login password to a first account corresponding to a post; receiving a login request sent by a user terminal; and responding to the login request, and sending data information of the first account binding with a first login password to the user terminal, to make the user terminal display the data information. The present disclosure further provides an identity recognition apparatus, system and a server. According to the identity recognition method, apparatus, system and the server, an account is set to have a corresponding relationship with a post, thus a successor of the post can browse historical-data information of the account corresponding to the post through the login password. Thusly, the user experience is good.

Abstract: A multi-way valve includes a valve seat and a valve core. The valve core is rotatably disposed in the valve seat, the valve seat is provided with a plurality of valve port groups, each valve port group includes a plurality of valve ports, the valve core is provided with communication structure groups corresponding to the valve port groups, respectively, and each of the communication structure groups further includes a plurality of communication structures arranged along a circumferential direction of the valve core. When the valve core is rotated to different rotation positions, valve ports in different valve port groups form different communication states. Only one valve core is required to make a two-way proportional valves, three-way proportional valve, and a four-way proportional valve achieve different communication states, with simple control, compact structure and low cost.

The method includes: obtaining a data set including a motor speed corresponding to a current time point, an actual current and an actual torque; determining a limit current at the current time point according to the motor speed; in response to the limit current being less than the actual current, determining a deviation value at the current time point according to the limit current and the actual current; determining a target requested torque based on the deviation value and the actual torque; and determining the bus current according to the target requested torque.

Abstract: A transmission system avoids activation of a sailing functionality in a vehicle. The transmission system is configured for automatic gear-shifting in an automatic mode and manual gear-shifting by a user in a manual mode. The transmission system includes a user input device configured for manually changing the operational mode between the automatic and manual modes. The transmission system includes a transmission control unit for determining a recommended gear in the automatic and manual modes. In the manual mode, an operating gear of the transmission system is detected by the transmission control unit. A change of the operational mode from manual to automatic by means of the user input device is detected, and if the detected operating gear in the manual mode when changing to automatic mode is lower than the recommended gear, the sailing functionality in the automatic mode is deactivated.

Abstract: An optical lens system for vehicle lighting includes a light guide with optical elements arranged as indentations in a light impacting surface of the lens body. The optical elements are configured with a truncated cone section arranged within the lens body in connection to the light impacting surface, and a rounded cap section arranged within the lens body in connection to the truncated cone section. A base surface of the rounded cap section is coincident with a top surface of the truncated cone section. The truncated cone section has an outer surface and a base surface, and the rounded cap section includes an outer surface. A cross-sectional transition between the outer surface of the truncated cone section and the outer surface of the rounded cap section is non-linear.
