Abstract
A brake system for a vehicle includes brake cylinders operated by pressurized fluid for actuation of brakes by means of pressurized fluid on at least one first axle of the vehicle. The brakes on at least one other, second, axle can be actuated exclusively electromechanically in response to an electrical braking request signal. The pressure of the pressurized fluid can be modulated indirectly or directly and the electrical braking request signal can be generated indirectly or directly in response to actuation of a brake pedal of a brake pedal device. A service brake function is provided by means of hybrid use of the brakes on the first axle(s) together with the brakes on the second axle(s). The brake cylinders operated by pressurized fluid are pneumatically operated brake cylinders. The pressure modulated by the brake pedal device is a pneumatic pressure, and the pressurized fluid is compressed air.
