Abstract:
The invention relates to a method for controlling a solenoid valve, especially in a motor vehicle. The inventive method is characterized by applying a first voltage (U_1) to a coil (21) of the solenoid valve (22) until a first point in time (t_1) and then applying a second voltage (U_2), having a smaller value. The first point in time (t_1) lies before the solenoid valve (22) has reached its final position.
