A method for electronically controlling a pneumatic brake system in a vehicle includes determining that a failure or a defect has occurred in electronic actuation of wheel brakes of the pneumatic brake system, and electronically actuating a pilot valve via a redundancy signal in response to determining that the failure or the defect in the electronic actuation has occurred so as to actuate the wheel brakes in a redundant electropneumatic manner. The redundancy signal is specified in such a manner that the pilot valve alternately turns for a pulse time into a second switch position and for a pause time into a first switch position. The pilot valve outputs, as a pilot pressure, a low pressure level in the first switch position and a high pressure level in the second switch position. The wheel brakes are actuated using a service brake braking pressure that is dependent upon the pilot pressure.
