GRAND BLANC, Mich., May 24, 2022 / PRNewswire / – Leveraging the technology components of its parent companies, Nexteer Automotive and Continental Automotive, CNXMotion expands its Brake-to-Steer (BtS) technology with two new software features that provide security layers for to all variants of the electrical direction. (EPS) and Steer-by-Wire (SbW) systems and 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

  • Support for automatic driving: SAE levels 4-5 (launched in 2020)

“These new Brake-to-Steer software features further enable security redundancies across all power steering applications and SAE driving levels without the cost and complexity of additional hardware,” he said. Greg Katch, General Manager, CNXMotion. “Our advanced Brake-to-Steer technology can help ensure that the safety net is always active by supporting driver effort and cable steering support, as well as automated driving support.”

Support for the effort of the steering brake driver

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

Brake cable steering support

SbW replaces the mechanical steering connection between the handwheel and the road wheels with algorithms, electronics and actuators. In this type of steering system, the BtS SbW support function adds another layer of security by translating the driver’s steering inputs into the control of the vehicle’s side-movement brake system.

Support for automatic steering brake control

Launched in 2020, CNXMotion’s original BtS feature pioneered the use of electronic braking as an additional layer of steering control for traditional, highly automated, autonomous vehicles (SAE levels 4-5). This BtS function got a Automotive news PACEpilot innovation to see in 2021.

“Brake-to-Steer’s expanded software features highlight how collaboration through our CNXMotion joint venture with Continental leads to innovation in motion control solutions and further enhances steering network security for at all levels of assisted and automated driving, “he said. Robin Milavec, President, Chief Technology Officer (CTO), Chief Strategy Officer (CSO) and Chief Executive Officer of Nexteer Automotive. “When combined with Nexteer’s advanced and industry-leading steering systems such as Steer-by-Wire or high-availability EPS, Brake-to-Steer offers OEMs a cost-effective and flexible way to add another layer of security and redundancy “.

Advantages of steering brake for drivers and OEM:

  • Value: Take advantage of the vehicle’s existing steering, braking and drive systems. The functions of the portable software can reside in an existing driver, eliminating the cost of any additional hardware.

  • Flexibility: Provides an additional layer of vehicle security and redundancy in all vehicles with EPS and SbW. The three functions of the BtS software cover all types of vehicles with or without a driver.

  • Security: Improves security with an extra layer of address redundancy.

“As the industry moves toward highly automated, autonomous vehicles, Brake-to-Steer’s advanced features enable critical safety features at all levels, enabling greater safety for all road users,” he said. . Lutz Kuehnke, Head of Security and Movement Business Area, Continental Automotive, North America. “CNXMotion’s Brake-to-steer technology offers a flexible and cost-effective way to achieve and prioritize safety needs by leveraging existing in-vehicle systems, such as Continental’s 1-box MKC1 brake control unit, and eliminating the need for additional components.
