Abstract
The invention relates to an injection mould (100) for producing a warning device (1) for monitoring a filling level of a container, in particular for a pressure medium container (2) of a hydraulic motor vehicle brake system, wherein the warning device (1) has an electrical interface unit (3), a filling level sensing unit (4) and an electronic signal processing unit (5) as well as a corresponding warning device and a method for manufacturing same. In order to produce multiple variants of warning devices (1) with a high level of functional safety more quickly, and with reduced costs and reduced expenditure on fabrication, the invention proposes that the injection mould (100) for producing a single-piece plastic housing (6) of the warning device (1) is constructed in a modular fashion with at least three mould components (10;11;12), wherein at least two of the mould components (10;11;12) are embodied as exchangeable inserts.
A method of detecting lanes includes the steps: capturing (S1) a camera image (K) of a vehicle environment by a camera device (2) of a vehicle (5); determining (S2) feature points (P1 to P15) in the camera image (K), which feature points correspond to regions of possible lane boundaries (M1, M2); generating (S3) image portions of the captured camera image (K) respectively around the feature points (P1 to P15); analyzing (S4) the image portions using a neural network to classify the feature points (P1 to P15); and determining (S5) lanes in the vehicle environment taking account of the classified feature points (P1 to P15).

A drum brake (1) for a motor vehicle has a pocket (9) for collecting abraded brake particles. The pocket (9) is accessible from the top via an opening (11). After the introduction of a suction means (13) into the opening (11), the abraded brake particles can be extracted by suction. As a result, pollution of the environment with abraded brake particles is avoided.
The invention relates to an electric drum brake for a rotatable element of a car, the drum brake having a brake drum and a braking surface connected thereto for conjoint rotation, and an electromagnet assembly, wherein multiple brake shoes can be pressed against the brake drum by means of the electromagnet assembly, and wherein the drum brake has a preloading assembly which preloads the electromagnet assembly into a position spaced from the braking surface.

Abstract
The invention relates to a pedal operating unit (100) having a brake pedal (102), which is mounted pivotably about a first pivot shaft (106), and a restoring mechanism, the restoring mechanism being designed to apply a restoring force to the brake pedal (102) in the direction of the rest position of the brake pedal when the brake pedal (102) is deflected out of its rest position. The restoring mechanism has at least one first restoring device (110) and one second restoring device (112). According to the invention, an increase in the restoring force is effected, in particular exclusively, by the first restoring device (110) over a first angle range of a pivot of the brake pedal (102) about the first pivot shaft (106), and an increase in the restoring force is effected, in particular exclusively, by the second restoring device (112) over a second angle range of a pivot of the brake pedal (102) about the first pivot shaft (106).
The invention relates to a method for error evaluation in position determination, comprising time-synchronous recording of first and second position values, wherein the second position values are recorded by a different measuring method than the first position values; forming a first and a second trajectory (A, B) from the first and the second position values respectively; forming differential vectors (D) between first and second position values recorded at the same time; parallel-shifting the second trajectory (B) along a displacement vector (s) such that the amounts of the differential vectors (D) are minimized on average; evaluating the faultiness of the position determination on the basis of one or more amounts of the differential vectors (D) created as a consequence of the parallel shift.
