A computer-implemented method for testing a system for at least one requirement. The method includes: the requirement is received in machine-readable form, at least one first input variable is ascertained for the test of the system for the received requirement, a design of the system is simulated as a function of the ascertained first input variable, an output variable of the simulated system is ascertained and it is ascertained as a function of the output variable whether the system meets the requirement, it is checked whether the simulation meets a quality requirement, if the simulation meets the quality requirement and the system meets the requirement, it is checked whether a sufficient test coverage is reached for the requirement, if the sufficient test coverage for the requirement is reached, the test for the requirement is completed.

A method for monitoring a drive-by-wire system of a motor vehicle, including: temporally offset reading in of at least two input values of an input quantity of an operating element of the motor vehicle; ascertaining a change over time or rate of change over time of the input quantity from the at least two read-in input values; determination of a monitored quantity for the motor vehicle operation from the change over time or rate of change over time; selection of a monitoring function on the basis of the monitored quantity; monitoring of the monitored quantity for the ascertained motor vehicle operation by the monitoring function.

A method for determining whether an error is present or not in a motor vehicle, a discrete state, in which the motor vehicle is presently in, being ascertained with the aid of a state machine, a decision being made, depending on the ascertained discrete state, whether an error is present or not, whereby the states of the state machine include acceptable states and unacceptable states, then, if the ascertained discrete state is an unacceptable state, the motor vehicle is transferred into an acceptable state.

In a method for checking the plausibility of objects in driver assistance systems for motor vehicles is described, two measured variables are derived from position data from two object position-finding systems of the vehicle that operate independently of one another, for an object located by the two position-finding systems, one variable for each position-finding system, these variables representing one and the same physical parameter, and the two measured variables are then checked for consistency, which is characterized by the fact that the parameter is the time to collision of the vehicle with the object, which is calculated in advance.

A method for activating a two-stage switching valve including a first stage which has a small flow cross-section and a second stage which has a larger flow cross section, the switching valve being situated between a main brake cylinder and a hydraulic pump in a hydraulic brake system. The pressure equalization knock on opening the switching valve is substantially reduced by activating the switching valve in a first control phase via a control signal having a low amplitude, due to which only the first stage of the valve is first opened, and by activating the valve in a second phase via a control signal having a higher amplitude.

Electric motor, as well as a brush mount component () for positioning of carbon brushes with respect to a commutator () of an electric motor (), having at least one attachment means () for fixing the brush mount component () on a printed circuit board (), with an earth contact plate () being mounted on the brush mount component () and being designed symmetrically with respect to the arrangement of the carbon brushes (). A method for production of an electric motor such as this is also described.

A device for determining the saturation point of a vacuum brake booster having a vacuum chamber and a working chamber that are separated from one another by a membrane. The reaching of the saturation point can be recognized simply and precisely if the vacuum prevailing in the vacuum chamber is measured using a pressure sensor, and the output signal of the pressure sensor is evaluated by an electronic evaluation system that calculates the saturation point using a mathematical function, taking into account only the pressure prevailing in the vacuum chamber.
