BRAKE SYSTEMS FOR SUPERCARS AND HYPERCARS – PERFORMANCE AT THE HIGHEST LEVELS!
When the subject changes to supercars and hypercars, you can almost see the excitement in the eyes of car fans and engineers! Like no other vehicle category, supercars and hypercars combine visionary invention with complex engineering and absolute performance!
They simply contain the best of what is possible today – and show what the future definitely holds. And that claim applies to every single component, system and technology involved. There are also the special requirements of the automobiles of the future, including e-Mobility and autonomous driving.
We are proud to be able to meet these lofty demands with our Brake-by-Wire X-Boost brake system.
The X-Boost is installed at the firewall and contains three different modules:
Modul I: Pedal Interface
Unlike ordinary brake systems, the X-Boost has no hydraulic coupling between the brake pedal and the brake calipers during normal operation mode.
An integrated emulator controls and maintains consistent pedal feel during regenerative braking. The emulator can also of course be customized based on customer preferences.
Driver deceleration is picked up by sensors in the pedal interface, which detects travel, force and pressure. These signals are then translated into target torque for the traction motor and target pressure for the calipers, all generated by the internal pressure supply unit.
Modul II: Pressure Supply Unit (PSU)
The core of the X-Boost system is our highly efficient Pressure Supply Unit. Designed and manufactured in house, the EC motor drives a ball screw that translates the motor’s rotary motion into a longitudinal movement of the pressure piston. This generates braking pressure as well as enables precise and dynamic control due to minimum friction hysteresis.
Modul III: Hydraulic Control Unit (HCU)
The HCU contains the system’s valves and pressure sensors. The pressure sensors detect driver intent and control output pressure to the wheels. The valves enable a fast and safe switch between active and variable fall-back modes to ensure safe braking capability in any situation.

Autonomous driving makes ESC systems and electromechanical brake boosters even more important than before. LSP faces up to this trend and compares electromechanical brake boosters under consideration of an increasing degree of SAE automation. As a new development, the compact X-Boost brake booster is presented here, which is characterized by a very light and narrow design.
