PolestarIPS Hydraulic Braking Architecture
Worldwide Patents Granted
Technology Readiness Levels 1 + 2 achieved.
Acquire the protected architecture, associated engineering work and the right to develop, license and enforce the acquired IP within its verified scope and territories.
A different route to braking
The disclosed architecture is intended to generate braking resistance through a transmission-integrated hydraulic mechanism rather than conventional wheel-end friction components.
Double-acting hydraulic cylinders react against a cam coupled to the transmission output shaft, converting rotational energy into hydraulic pressure.
The IP position addresses three related areas:
Hydraulic braking architecture Kinetic-energy recovery
Integral passive hydraulic anti-lock braking
A strategic opportunity
A route away from brake-wear particulate emissions;
Potential reduction of wheel-end braking hardware and unsprung mass, subject to vehicle-level engineering;
Hydraulic pathways for energy recovery and thermal management that merit quantified testing;
A protected position that can be evaluated across commercial vehicles, passenger vehicles, specialist transport and industrial motion control.

About the Inventor: Charan Nelms (Jim)
With over 30 years as an independent concept designer and inventor in the automotive sector, Jim Nelms has a proven track record of innovation:
- Q-Damper Multi-Adjustable Damping System: Debuted at the 1996 Racing Car Show (NEC Birmingham). Remains the gold standard, adopted by all Formula 1 teams and integrated into products by global manufacturers.
- The Quadrant: A range of adjustable shock absorbers that redefined vehicle dynamics.
- Other breakthroughs: crankless internal combustion engines, frictionless clutch systems, zero-displacement shock absorbers, hydraulic pumps/motors, and consumer innovations like anti-burn cooking vessels and interdental toothbrushes.
Jim’s expertise positions FBS as the next evolution in braking technology, building on his legacy of practical, high-impact inventions.
Technology Overview
FBS replaces conventional friction braking with a hydraulic cam-integrated system tied to the transmission output shaft. Here’s how it works:
- Core Mechanism: Double-acting hydraulic cylinders engage a cam on the transmission output shaft, pumping oil via hydraulic pressure.
- Handbrake Integration: Oil flows to a handbrake valve—ON locks the system (stops cam rotation, immobilising the vehicle); OFF routes oil to the master cylinder.
- Braking Action: Depressing the brake pedal restricts oil flow through the master cylinder, imposing hydraulic force on the cam. This retards the transmission shaft, slowing/stopping the vehicle proportionally.
- Variants:
- Hydraulic braking system.
- With an integral passive anti-lock braking system (ABS)—no computer needed.
- With Kinetic Energy Recovery (KER) for energy recapture.
Key Advantages of FBS
FBS isn’t just an alternative—it’s a superior solution, addressing critical pain points in traditional braking:
| Advantage | Benefit | Impact |
| Zero Particulates | No brake dust from pads/discs | Cleaner air; reduces cancer risks; complies with tightening emissions regs (e.g., EU CAFE standards). |
| Energy Recycling | Heat from braking supplements A/C, refrigeration (e.g., cargo vans), or generates electricity | Lowers carbon footprint, cuts fuel use by 5–10%, fights global warming and reduces carbon footprint. |
| Integrated Passive ABS | No electronic controllers; inherent lock prevention | Reliable in all conditions; cost savings on ECUs/sensors. |
| Weather-Independent | Unaffected by rain/snow | Enhanced safety; no fade like disc systems. |
| Lower Servicing & Costs | Fewer parts (no pads/discs to replace) | 30–50% cheaper over the lifecycle; easier servicing with low maintenance. |
| Dynamic ABS Integration | Seamless add-on capability | Customisable for high-performance vehicles. |
| Reduced Unsprung Mass | Lighter braking components | Improved steering, road holding, and efficiency (up to 2–5% better handling). |
