Disclosed in the present application are a method for generating a speed control model, a vehicle control method and an apparatus. The vehicle control method comprises: acquiring the current geographic location of a target vehicle and a target speed control feature corresponding to the current geographic location, the target speed control feature being a feature that affects the speed of the vehicle; inputting the current geographic location and the target speed control feature corresponding to the current geographic location into a speed control model to obtain the current target speed of the target vehicle, the speed control model being generated by training starting coordinates and ending coordinates of each preset lane segment in the map data, the target speed control feature and a speed control label in the preset lane segment; and controlling the target vehicle to drive according to the current target speed.

The invention provides a high-resolution QD pixelated light-emitting film and method for preparing same. The method includes: spin-coating a photoresist on a base; drying and exposing the base; coating a developer at a preset position on the base to obtain a photoresist pattern layer; depositing an insulating layer on the photoresist pattern layer by using silane; removing a photoresist pattern in the insulating layer; spin-coating a polyethylenimine solution on the insulating layer to obtain a PEI layer; and dropping a QD solution on the PEI layer to deposit a QD layer. The hydrophobicity of silane is used to implement dewetting to implement QD pixilation. A PEI solution is spontaneously deposited at the position of a photoresist pattern. Further, the QD solution is adsorbed into the PEI solution to obtain a high-resolution QD pixelated light-emitting film, thereby improving the film forming quality, and passivating surface defects of a QD layer.

Disclosed in the present disclosure are a method and an apparatus for determining a vehicle speed control model training sample. The method includes: a lane in map data is divided into a first lane area and a second lane area, and to-be-measured vehicle speed control features indicated by the two lane areas are different; the to-be-measured vehicle speed control features are determined as target vehicle speed control feature when a difference between a first empirical highest vehicle speed distribution and a second empirical highest vehicle speed distribution is greater than or equal to a preset difference threshold; and starting coordinates and ending coordinates of each preset lane section in the map data, and the target vehicle speed control features and a vehicle speed control label in the preset lane section are taken as a vehicle speed control model training sample.

An electronic device includes an enclosure, a display positioned with the enclosure and defining a front face of the electronic device, and a haptic actuator positioned within the enclosure. The haptic actuator includes a housing comprising a wall and a movable mass positioned within the housing and configured to move within the housing to cause the haptic actuator to produce a vibrational response. The vibrational response includes a first component within a frequency range and a second component outside of the frequency range and providing a haptic output portion of the vibrational response. The haptic actuator also includes a tuning feature incorporated with the wall and configured to reduce the first component of the vibrational response while substantially maintaining the haptic output portion of the vibrational response.
