Abstract: In a method for vehicle positioning, a positioning apparatus in a to-be-positioned vehicle obtains a global positioning system (GPS) position covariance of the to-be-positioned vehicle. When the GPS position covariance is less than or equal to a preset position covariance threshold, the apparatus obtains initial position information of the to-be-positioned vehicle and vehicle information of a surrounding vehicle. The apparatus determines a first position reckoning result of the surrounding vehicle based on the initial position information of the to-be-positioned vehicle and the vehicle information of the surrounding vehicle, and determines a second position reckoning result of the to-be-positioned vehicle based on the first position reckoning result.

Abstract: The present disclosure relates to vehicle positioning methods, apparatus, controllers, intelligent vehicles, and systems. One example vehicle positioning method includes obtaining a first relative pose between a first vehicle and a help providing object, obtaining a global pose of the help providing object, and calculating a global pose of the first vehicle based on the first relative pose and the global pose.

Abstract: Disclosed are a tube pure shear loading device and method. A first mandrel penetrates into a first half tube, and a second mandrel penetrates into a second half tube. The size of the first mandrel matches the size of the first half tube, and the size of the second mandrel matches the size of the second half tube. A first connecting portion of the first mandrel and a second connecting portion of the second mandrel are loaded, and a first protruding portion and a second protruding portion transmit a force to a to-be-tested tube, so that a material of a whole tube in the same plane as a right plane or a left plane of the first half tube and a left plane or a right plane of the second half tube is in a pure shear stress state.

Abstract: Disclosed are a method and a device for controlling refrigerant in an air conditioning system. The method includes: S1: comparing a superheat degree of each outdoor unit with an average superheat degree; S2: if the superheat degree of a present outdoor unit is higher than the average superheat degree, and a first different between the superheat degree of the present outdoor unit and the average superheat degree is greater than a present value, increasing a refrigerant amount entered into the present outdoor unit; and S3: if the superheat degree of the present outdoor unit is lower than the average superheat degree, and a second different between the average superheat degree and the superheat degree of the present outdoor unit is greater than the present value, decreasing the refrigerant amount entered into the present outdoor unit. Therefore, the refrigerant amount entered into each outdoor unit is adjusted from systemic overall perspective.

Abstract: In an air conditioning system of the present disclosure, the controlling module determines state of the indoor unit. If the indoor unit is under off state, the controlling module determines whether an indoor temperature is smaller than a preset temperature. If yes, the controlling module controls the indoor unit to heat according to a first heating temperature. If the indoor unit is under heating state, the controlling module sets a second heating temperature of the indoor unit to the first heating temperature, and controls the indoor unit to heat according to the first heating temperature. The first heating temperature is smaller than the second heating temperature. If the indoor unit is under cooling state, the controlling module sets a first cooling temperature to a second cooling temperature which is greater than the first cooling temperature, and controls the indoor unit to cool according to the second cooling temperature.

Abstract: The embodiment relates generally to a stamping or draw die used for forming a workpiece into a part or component using a first die shoe, a second die shoe and a punch wherein the punch draws the material into a cavity located in the second die shoe. The force is generated during the forming operation are often unbalanced which generates an uneven stress distribution on the component of the die assembly. By varying the position and angle of the guide surfaces located on the punch, first die shoe and second die shoe the stress can be distributed across a greater area of the respective die assembly component to reduce stress concentrations in a localized area and correspondingly reduce the potential for die failure.
