The embodiment of the application provides a kind of electronic hydraulic brake and electronic parking brake collaborative control method of unmanned vehicle, this method includes: when electronic hydraulic brake unit is used to brake vehicle, according to the current state signal of vehicle, it is judged whether vehicle enters effective zero speed state;When vehicle enters effective zero speed state, send clamping trigger instruction to electronic parking brake unit, to make electronic parking brake unit start to execute clamping action;In the whole process that electronic parking brake unit starts to execute clamping action to clamping force reaches target clamping force, electronic hydraulic brake unit maintains current brake pressure unchanged, to make vehicle keep still;When it is detected that the clamping force of electronic parking brake unit reaches target clamping force, electronic hydraulic brake unit starts to release pressure with preset pressure relief slope, until the brake pressure of electronic hydraulic brake unit drops to target pressure relief pressure.Using this method, smooth braking, accurate parking and reliable parking of vehicle are realized.

The utility model relates to the field of electrical engineering, in particular to an electric porcelain insulator electric detection assembly line device. The utility model provides an electric porcelain insulator electric inspection assembly line device, which comprises a rack, a plate chain type conveyor, placing dies, electric inspection equipment and the like, the plate chain type conveyor is arranged in the rack, a plurality of placing dies are connected to a plate chain of the plate chain type conveyor, and the electric inspection equipment is arranged on the upper side of the rack. Through the arrangement of the motor, the full gear and the missing gear, the output shaft of the motor drives the missing gear to rotate, and in the periodic meshing and separating process of the missing gear and the full gear, starting and stopping of the connecting shaft and the plate chain type conveyor are controlled, so that precise stepping conveying of a placement mold and an electric porcelain insulator on the placement mold is achieved; the automation degree of the detection process is effectively improved, it is ensured that each row of electric porcelain insulators can be accurately stopped under electric detection equipment, and reliable mechanical transmission guarantee is provided for efficient and accurate electric performance detection.

The invention discloses a two-wheeled vehicle garage buffer mechanism and a two-wheeled vehicle garage, and relates to the technical field of two-wheeled vehicle garages. The device comprises a bottom plate, a grating frame, a fence and a rain shelter are sequentially fixed to the top of the bottom plate, the grating frame is located on the inner side of the fence, controllers are fixed to the two sides of the fence, a sliding rail is arranged on the outer wall of the lower portion of the grating frame, and a plurality of sliding plates are slidably mounted in the sliding rail; driving assemblies are arranged in a plurality of grids of the grid frame, vehicle carrying plates are fixed to the moving ends of the driving assemblies and the outer walls of the sliding plates, and front wheel brackets are fixed to the tops of the vehicle carrying plates. Through the arrangement of the buffer device, under the action of the elastic force of the buffer spring corresponding to the U-shaped inclined plate, the buffer spring can effectively reduce the impact pressure of a vehicle on the U-shaped inclined plate and other parts of the garage, the damage and abrasion of the garage structure are reduced, and the service life of the garage is prolonged.

The application provides a precise parking auxiliary control method and device for an electric vehicle and a medium, and belongs to the technical field of wireless charging of electric vehicles. After detecting that an electric vehicle enters a parking place, a charging parking space matched with the charging system of the electric vehicle is screened, a parking instruction carrying target charging parking space information is received, and target charging parking space information, target center point coordinates at a standard parking position of the target charging parking space, and target edge angle point coordinates are sent to the electric vehicle. In the process of the electric vehicle driving into the target charging parking space position, current edge angle point coordinates and current center point information of the electric vehicle are acquired in real time, and it is determined whether the electric vehicle is parked in the middle position of the target charging parking space. If not, the steering angle of the electric vehicle is adjusted, the electric vehicle is controlled to enter the middle position of the target charging parking space based on the adjusted steering angle, precise parking is finally realized, and the charging efficiency of the electric vehicle is improved.
