Embodiment Construction

[0093] In the figures, the same reference numerals are used for components having the same or equivalent function and / or design. If the same parts are used several times in an embodiment, these parts are marked with the same reference numerals and an additional distinguishing letter a, b, c, . . . or A, B. The use of a reference number in the following description without distinguishing letters a, b, c, ... or A, B may refer to all parts with this reference number, or to only a single part or any number of these parts. If the same component or component group is used multiple times for an embodiment, only one of these components or component groups will be described in some cases. In this case, however, the other components or groups of components apply correspondingly.

[0094] figure 1 An electric braking system 1 is shown. The electric braking system 1 comprises four braking devices 2a-2d. The brake devices 2a-2d respectively comprise brake actuators 3a-3d respectively...

Abstract

The invention relates to an electric brake system (1) for a vehicle. The electric brake system (1) comprises electric brake devices (2). The electric brake devices (2) are powered and controlled by redundant capacitor-based power sources (9A, 9B) and redundant control circuits (16A, 16B). The capacitor-based power source (9A, 9B) can be integrated into axle modules (39A, 39B) located close to a vehicle axle (61A, 61B). The capacitor-based power sources (9A, 9B) are recharged by a hub generator, a regeneration power source (32).

Description

technical field [0001] The invention relates to an electric braking system for a vehicle, by way of example only, in particular a commercial vehicle, a vehicle propelled exclusively by electric energy and / or a hybrid vehicle propelled by electric energy and an internal combustion engine. The vehicle may be a bus, commercial vehicle, tractor, train and / or trailer. In this type of vehicle, in the electric braking system, the braking force is generated by at least one electric braking device. In an electric brake device, the contact force between brake elements, especially brake pads and brake discs, is controlled by an electric brake actuator. Background technique [0002] EP 1 302 371 A2 describes a known power supply system according to DE 197 55 050.9. In this power supply system, electro-motoric braking devices are powered by two redundant power supplies through a common power supply line. A redundant power supply ensures that the brakes can also be operated in the even...
