Method and device for error-compensated current measurement of an electrical accumulator

A method for error-compensated current measurement of an electrical accumulator, including: providing a time window-related estimated charge ascertained by a model-based estimator from operating variables of the accumulator and reflecting the estimated charge that has been withdrawn from the accumulator and supplied to the accumulator within the time window; and detecting the accumulator current supplied to the accumulator and withdrawn from the accumulator during the time window, with a current detection sensor. A zero crossing point in time (estimated charge is essentially zero) and a maximum point in time (the absolute value of the estimated charge essentially has a relative maximum or has a value which is greater than a minimum charge difference) are detected. A current measurement offset error is ascertained at the zero crossing point in time by comparing the estimated charge to the detected accumulator current. The accumulator current is ascertained according to the current measurement offset error, and a current measurement scaling error is ascertained at the maximum point in time by comparing the estimated charge to the detected accumulator current. The ascertained current measurement offset error is subtracted from the comparison result thus obtained, and the accumulator current is compensated for based on the current measurement scaling error. A related device for error-compensated current measurement is also described.

Method and device for the serial production of a vehicle assembly, bearing unit, vehicle steering wheel and horn module for a steering wheel assembly and steering wheel assembly

A method for series production of a vehicle assembly, especially an interior assembly, including a vehicle-side support, especially a vehicle steering wheel (12), and a component to be fastened at the support, especially a horn module (14), wherein a module-side bearing unit (22) consisting of at least two bearing members (46, 50) is assigned to the component and/or a support-side bearing unit (24) consisting of at least two bearing members (26, 28) is assigned to the support, and wherein one of the bearing members (28, 50) of the respective bearing unit (22, 24) has a contact surface (34, 58) and the other one of the bearing members (26, 46) has at least one bearing surface (38, 54) includes the step of individually orientating the two bearing members (26, 28, 46, 50) of at least one bearing unit (22, 24) relative to each other as a function of the actual dimensions of the support installed and/or the component installed, fastening the two bearing members (26, 28, 46, 50) orientated relative to each other, and fastening the component to the support. The position of the support and the component relative to each other is defined by at least one bearing unit (22, 24).

Method for improving curing forming quality of L-shaped composite material laminated plate

ActiveCN109624353AAvoid uneven pressureInhibition of microbucklingElastomerFiber
The invention discloses a method for improving a curing forming quality of an L-shaped composite material laminated plate. The method comprises the following steps that (1), an elastomer material is selected, and an elastomer buffer flexible film is manufactured according to the contour dimension of a component; (2) vent holes are uniformly formed in the elastomer buffer flexible film in the thickness direction after the elastomer buffer flexible film is formed; and (3) the L-shaped composite material component is prepared, a prepreg laminated layer is paved on a rigid die according to the paving ratio, the outer surface of the laminated layer is covered with the prepared elastomer buffer flexible film, and a vacuum bag pressing method or a drying oven is adopted for curing and forming according to the set temperature and pressure curves. According to the method, the pressure borne by a part with the curvature of the composite material component in the forming process can be balanced through the introduction of the elastomer buffer flexible film, fibers can be prevented from generating micro-bending in the forming process, fiber wrinkles are prevented from being generated on the surface of the composite material laminated plate, and therefore the surface quality of the composite material laminated plate is improved, and the stability of the outer side dimension of the compositematerial component with the curvature is ensured.
