Improved braking distance with IWM

Conventional ABS is limited by hydraulic bandwidth. In-wheel systems change that boundary.

At Chassis.tech, Tomaž Kompara presented our Reactive Dual-Stage ABS work: a braking architecture where the mechanical brake carries the low-frequency, high-power braking load, while the in-wheel system handles high-frequency slip control directly at the wheel.

The important point is not only shorter stopping distance, it is control authority.

In many EV braking strategies, regeneration is reduced or handed over to friction braking as deceleration rises or ABS becomes relevant. With our control approach, the vehicle can safely use up to 100% of the available regenerative torque while maintaining stable slip control.

That means braking performance, smoothness, calibration effort, and energy recovery no longer need to be treated as competing targets.

The videos clearly show the difference, up to 14% shorter stopping distance in wet conditions and up to 7% shorter stopping distance in dry conditions:
