Brake system, method for operating the brake system, and vehicle

A method for operating a brake system, the brake system being for electronically controlled braking of wheels on at least two main axles of a vehicle via wheel brakes of the brake system, the brake system including a plurality of wheel speed sensors and at least two control units for generating and outputting brake control signals, the at least two main axles and at least one additional axle having at least one of the plurality of wheel speed sensors disposed thereon for outputting wheel speed signals on a basis of determined wheel speeds of the wheels on the at least two main axles and of the wheels on the at least one additional axle, the wheel brakes on the at least two main axles being configured to be controlled on a basis of the brake control signals, the wheel speed sensors on the at least two main axles being connected to the at least two control units via main data lines such that each of the at least two control units is configured to receive the determined wheel speeds via the wheel speed signals for each wheel on the at least two main axles to which at least one wheel speed sensor is assigned, and, each of the wheel speed sensors on the at least one additional axle being connected only to one of the at least two control units via an additional data line, and each of the at least two control units being in turn connected to at least one of the wheel speed sensors on the at least one additional axle, the method comprising:

• generating and outputting the brake control signals via the at least two control units of the brake system;
• controlling the wheel brakes on the at least two main axles on a basis of the outputted brake control signals;
• outputting the wheel speed signals via the wheel speed sensors on the at least two main axles and on the at least one additional axle of the brake system, wherein the wheel speed signals are generated on a basis of the determined wheel speeds of the wheels on the at least two main axles and of the wheels on the at least one additional axle;
• receiving at each of the at least two control units the determined wheel speed via the output wheel speed signals for each wheel on the at least two main axles, to which at least one of the wheel speed sensors is assigned, and the at least two control units being configured to generate brake control signals on a basis thereof;
• and,
• receiving and processing via each of the at least two control units the determined wheel speeds of at least one of the wheels on the at least one additional axle via the output wheel speed signals, wherein each determined wheel speed of the wheel on the at least one additional axle is simultaneously received and processed only by one of the at least two control units.
