  • Patent number: 11945321
    Abstract: Technologies and techniques for charging a high-voltage battery of an electric drive of a vehicle, in which electrical power is transmitted from a low-voltage on-board electrical system of the vehicle to the high-voltage battery, and, to aid starting of the vehicle, electrical power is transmitted from a separate external unit to the low-voltage on-board electrical system of the vehicle and is transmitted from the low-voltage on-board electrical system to the high-voltage battery. The present disclosure also relates to a related power transmission system.

  • Patent number: 11919414
    Abstract: The invention relates to a method involving a vehicle or an inductive charging station for positioning the vehicle on the inductive charging station, at least having the method steps: determining vehicle-specific first identification information; determining charging station-specific second identification information; transmitting the first identification information and the second identification information to a storage apparatus; receiving positioning information, assigned to the combination of first identification information and second identification information, from the storage apparatus.

  • Publication number: 20230303128
    Abstract: A driver assistance method by a control device is to receive driving environmental data from identically constructed motor vehicle sensor technologies of a first motor vehicle, as well as from at least one further motor vehicle, which drive on a set road section in an at least partially autonomous driving mode. Each motor vehicle may provide a road section model for each of the motor vehicles with an algorithm recorded in each respective motor vehicle. The control device examines the road section models and/or the algorithms for a feasibility of the at least partially autonomous driving mode for the first motor vehicle, evaluates the algorithms of each motor vehicle based on a comparison of the road models, and sets that algorithm, which satisfies the set feasibility criterion with the highest probability, as the target algorithm.

  • Patent number: 9739324
    Abstract: The invention relates to a brake lining assembly, particularly for drum brakes, comprising a brake shoe having an outer contour, a brake lining having an inner contour, and an intermediate layer having an outer contact region and an inner contact region. The intermediate layer is arranged between the brake shoe and the brake lining, and the intermediate layer is formed, as viewed radially with respect to an axis of rotation of the brake shoe, in such a manner that the inner contact region is matched in a form-fitting manner to the outer contour of the brake shoe in a circumferential direction of the brake shoe. The outer contact region is matched in a form-fitting manner to the inner contour of the brake lining along the circumferential direction.

  • Patent number: 8863916
    Abstract: A brake shoe, in particular a brake shoe for a drum brake, comprising a bridge unit and a brake pad unit, wherein the bridge unit comprises a bridge element with an at least partially arched geometry and a bridge-sided connecting portion, the brake pad unit comprises a brake-pad-sided connecting portion, and the brake-pad-sided connecting portion and the bridge-sided connecting portion are configured such that they positively engage each other at least in a certain area so that the positive engagement prevents, in at least one direction, the brake pad unit dislocating relative to the bridge element.
