CNXMotion Expands Brake-to-Steer Technology with New Software Functions

Further leveraging technology building blocks from its parent companies, Nexteer Automotive and Continental Automotive, CNXMotion expands its Brake-to-Steer (BtS) technology with two new software functions that provide backup safety layers for all variants of Electric Power Steering (EPS) and Steer-by-Wire (SbW) systems and across all SAE levels of driving automation (levels 1 – 5).

CNXMotion’s BtS technology portfolio includes:

  • Driver Effort Support: SAE Levels 1-3 – NEW
  • Steer-by-Wire Support: SAE Levels 1-5 – NEW
  • Automated Driving Support: SAE Levels 4-5 (launched in 2020)

EPS systems are designed with multiple protective layers to ensure the steering safety net is always on. When paired with a traditional EPS system, BtS Driver Effort Support adds another safety layer and can provide up to an additional 25% reduction in torque. While steering traditionally manages the lateral control of a vehicle, BtS enables the braking and powertrain systems to contribute to lateral control to reduce steering efforts when necessary.

SbW replaces the mechanical steering connection between the hand wheel and road wheels with algorithms, electronics and actuators. In this type of steering system, the BtS SbW Support function adds another safety layer by translating the driver’s steering inputs into brake system control of the vehicle’s lateral motion.
