Abstract: A method for determining a switching point of a solenoid valve. A solenoid coil is energized to raise a solenoid armature to unblock a flow opening. For a signal profile characteristic of a current profile in the solenoid coil, multiple periods each different from one another and each having the same predefined temporal length are determined. Within each period, a minimal and a maximal value of the signal profile and associated points in time are ascertained and a product of a difference between the maximal and minimal value and a difference between the associated points in time are ascertained. On the basis of the points in time of the minimal and maximal value of that period, which corresponds to a maximal value of the product, the switching point is determined.

Abstract: A method for controlling at least one switchable valve, a brake impulse that slows down the valve movement being produced during the controlling of the at least one valve. At least one parameter of the brake impulse determines the position and/or the duration of the brake impulse. A parameter is modified, and the reaction of a measurement quantity or of a characteristic feature derived from the measurement quantity is evaluated.

Abstract: A method for controlling at least one switchable valve, a brake impulse that slows down the valve movement being produced during the controlling of the at least one valve, the position and/or the length of the brake impulse being specified as a function of a switching time of the valve, it being checked whether a characteristic feature occurs that indicates the switching time, and, upon occurrence of the characteristic feature, the position and/or the length of the brake impulse being adapted based on the position of the characteristic feature.
