A driving dynamics control system for an electric vehicle with a central domain control architecture, wherein the vehicle has at least one traction motor to accelerate and brake at least one axle of the vehicle, the driving dynamics control system comprising:
- at least one pressure supply device driven by an electromotive drive and controlled by a controller of the pressure supply device to supply pressure to at least one hydraulic circuit or one wheel brake, wherein the pressure supply device, the electromotive drive, and the controller of the pressure supply device are combined in one main module,
- and
- at least one superordinate control device having a domain or central processor with a redundant configuration,
- wherein the superordinate control device is electrically connected with the at least one traction motor of the vehicle and the controller of the pressure supply device,
- wherein the superordinate control device is configured to:
- control a brake function of the at least one traction motor of the vehicle, and
- control one or more of the following functions:
- brake force boosting, ABS, ESP, emergency braking, and/or distance control;
- and
- wherein the main module performs only pressure actuation functions when an ABS or ESP function is performed by the superordinate control device.
A driving dynamics control system for an electric vehicle with a central domain control architecture, wherein the vehicle has at least one traction motor to accelerate and brake at least one axle of the vehicle, the driving dynamics control system comprising:
- two pressure supply devices, each pressure supply device driven by a respective electromotive drive and controlled by a respective controller of the pressure supply device to supply pressure to at least one hydraulic circuit or one wheel brake,
- wherein the two pressure supply devices are disposed in two spatially separated main modules, with each main module including one of the two pressure supply devices with the respective electromotive drive and the respective controller of the pressure supply device,
- and
- at least one superordinate control device having a domain or central processor with a redundant configuration,
- wherein the superordinate control device is electrically connected with the at least one traction motor of the vehicle and both respective controllers of the pressure supply devices,
- wherein the superordinate control device is configured to:
- control a brake function of the at least one traction motor of the vehicle, and
- control one or more of the following functions:
- brake force boosting, ABS, ESP, emergency braking, and/or distance control.
A driving dynamics control system for an electric vehicle with a central domain control architecture, wherein the vehicle has at least one traction motor to accelerate and brake at least one axle of the vehicle, the driving dynamics control system comprising:
