Abstract
A device for a hydraulic actuating system, e.g., a motor vehicle brake, a clutch or a gear selector, may include the following components arranged in one housing, forming a main module: at least one pressure supply device driven by an electric motor drive, and a valve arrangement comprising at least one solenoid valve. The device may further include an electrical control unit (ECU) and valve output stages and sensors. The main module may be electrically and/or hydraulically connected to at least one further system component, which system component may include and actuating device and a travel simulator.
Claims13
A drive and braking system for a vehicle with a central domain control architecture and further with two brake circuits, comprising:
- at least one traction motor configured to be operated as a generator to brake a wheel or an axle of the vehicle;
- a pressure supply device, driven by an electromotive drive and controlled by a controller, and configured to change pressure in the vehicle's two brake circuits, wherein the pressure supply device and the controller are comprised by a main module, wherein the controller has a redundant power supply with two on-board electrical systems of the vehicle, wherein an electronic circuit board of the controller has two three-phase feed lines, and wherein drivers for each three-phase feed line are configured galvanically separated;
- a superordinate control device, which is electrically connected to the controller of the pressure supply device and to the traction motor;
- wherein the superordinate control device is configured to control a brake function of the traction motor;
- wherein the system further comprises an additional module with an actuating device, wherein the main module and the additional module are connected to one another via an electrical data and/or control line and a hydraulic line;
- wherein a piston-cylinder unit with a single-circuit master cylinder is arranged in the additional module, a piston of which is adjustable by means of the actuating device;
- wherein the additional module is connectable via a valve arrangement to at least one brake circuit or to at least one hydraulic consumer.
A drive and braking system for a vehicle with a central domain control architecture and further with two brake circuits, the system comprising:
- at least one traction motor configured to be operated as a generator to brake a wheel or an axle of the vehicle;
- a pressure supply device, driving by an electromotive drive and controlled by a controller, and configured to change pressure in the two brake circuits, wherein the pressure supply device and the controller are comprised by a main module, wherein the controller has a redundant power supply with two on-board electrical systems of the vehicle, wherein an electronic circuit board of the controller has two three-phase feed lines, and wherein drivers for each three-phase feed line are configured galvanically separated;
- a superordinate control device, which is electrically connected to the controller of the pressure supply device and to the at least one traction motor, wherein the superordinate control device is configured to control a brake function of the at least one traction motor,
- wherein the system either:
- comprises an additional module with an actuating device, wherein the main module and the additional module are connected to one another via an electrical data and/or control line, without a hydraulic connection between the main module and the additional module, or
- does not have a brake pedal.
