ABSTRACT:
A hydraulic braking circuit comprises at least one brake fluid source (26, 36), a master cylinder (10), the outlets of which are connected to at least one sub-circuit comprising at least one brake motor (14, 16), and which is controlled by way of a pedal (12), and an electronic control unit (22). It also comprises a pressure generator (24), and an electrovalve (28, 30) which is arranged in each sub-circuit, so as to establish a connection, when at rest, between the outlets of the master cylinder (10) and the associated brake motors (14, 16) and, in the excited position, between the outlets of the generator (24) and the associated brake motors (14, 16), the control unit (22) being capable of simultaneously controlling the functioning of the pressure generator (24) and the excitation of the electrovalve (28, 30).
