An invention relates to an electrically controlled braking system which is intended for use on a wheeled vehicle and has input means which can be actuated by a driver of the vehicle in accordance with the desired braking effect, two electronic control units, which operate independently of each other and each of which can be supplied with an electrical signal corresponding to the extent of actuation of the input means, which can be recorded by a sensor, a brake cylinder assigned to a wheel and a braking pressure modulator valve which is fluid-connected to the brake cylinder and has a first electric actuating element, which can be activated by a first of the two control units. To make the braking system very safe, the braking pressure modulator valve has a second electric actuating element which acts in the same direction when activated, as the first electric actuating element. The second electric actuating element can be activated by the second electronic control unit at the same time as the first electric actuating element is being activated by the first electronic control unit.
An electrically controlled braking system for a wheeled vehicle, comprising input means (33) which can be actuated by a driver of the vehicle in accordance with a desired braking effect, two electronic control units (25, 26), which operate independently of each other and each of which is suppliable with an electrical signal corresponding to extent of actuation of the input means (33), which is recordable by a sensor (35, 36), a brake cylinder (12) associated with a wheel of the vehicle, and a braking pressure modulator valve (13) which is fluid-connected to the brake cylinder (12) and has a first electric actuating element (18, 19), which can be activated by a first of the two control units (25, 26), and wherein, the braking pressure modulator valve (13) has a second electric actuating element (19, 18) which acts in the same direction, when activated, as the first electric actuating element (18, 19), and the second electric actuating element (19, 18) can be activated by the second electronic control unit (26, 25) at the same time as the first electric actuating element (18, 19) is being activated by the first electronic control unit (25, 26).
