Electrohydraulic Braking

Advanced ADAS features like adaptive cruise control and autonomous emergency braking require a braking system that offers both fast response times and smooth, precise modulation not achievable with conventional systems.

Our portfolio of ASIL-rated motor drivers and robust power management ICs enables the precise control of the electric motors and hydraulic pumps in EHB systems, ensuring dependable performance. To enable a seamless blend of driver-initiated and automated braking, providing the fast, smooth response necessary for both emergency situations and the nuanced control required for Level 2/3 autonomous driving features.
