Abstract: A method for operating a brake system. A brake request signal characterizing a brake request is generated by actuating a positioner system of an actuating circuit, and a setpoint brake pressure required in an active circuit is ascertained based on the brake request signal. An actual brake pressure is set in the active circuit according to the setpoint brake pressure using a pressure generation device by moving a displacement piston using an electric motor to actuate a wheel brake coupled with the active circuit. Under the condition that the brake request signal is constant over a predefined period of time, a pressure modulation is carried out, which includes setting the actual brake pressure in the active circuit to a value that is greater than the setpoint brake pressure, and lowering the actual brake pressure by moving the displacement piston using the electric motor until the setpoint brake pressure is reached.

Abstract: The present invention proposes a warning system that can be implemented in any kind of vehicle, in order to efficiently detect moving objects. The system utilizes at least one camera for a continuous imaging of the surroundings of the vehicle. Thereby, moving objects can be monitored. A computing unit is programmed to estimate a motion of any moving object based on a pixel motion in the camera image. If a dangerously moving object is detected, a warning unit can be used for issuing a warning signal. To take such a decision, the estimated motion of at least one of the moving objects can be correlated or compared to predetermined motion patterns.

A first image recording unit records a first image of the spatial area. The first image recording unit comprises an image sensor having a plurality of pixels. An evaluation unit determines a distance value for at least one spatial area point, which is located in the spatial area and is imaged on at least one pixel, by means of a propagation type measurement. The propagation type measurement suffers from a limited unambiguity range. Therefore, a test device is designed to check the distance value by means of a reference distance value determined from a second image of said spatial area.

A pixel failure is assumed if the actual noise factor misses a predetermined criterion defined by a reference noise factor. According to one embodiment, the reference noise factor is a dark noise factor. An electronic camera that operates in accordance with the above-described method is also disclosed.
